Citrus marketing in Punjab: constraints and potential for improvement.
Sharif, Muhammad ; Farooq, Umar ; Malik, Waqar 等
I. INTRODUCTION
Pakistan is blessed with the agro-ecological environment conducive to the production of nearly thirty types of fruits of which citrus,
mango, dates, guava, apple, melons and banana are relatively more
common. The market value of these fruits produced during 2002-03 is
estimated at about Rs 73 billion, which is roughly 6.73 percent of
agriculture value added in the year [Pakistan (2004)]. During the same
period, Pakistan earned nearly 5 billion rupees from fruit exports,
representing 9 percent of total export earnings from all raw
agricultural commodities. Citrus is the largest grown fruit in Pakistan.
The market value of citrus produced in 2002-03 was Rs 10.6 billion
[Pakistan (2004)]. Within the citrus family, Kinnow is the largest
planted specie.
Besides income, citrus is also significantly contributing to
employment generation through the various activities ranging from
production to domestic and international marketing activities. Assuming
that all the Kinnow produced in Punjab is domestically marketed, the
employment generated from Kinnow production and marketing is estimated
at about 23.48 million labour-days or full time round the year jobs for
more than 75 thousand people (about 57 thousand in production and
remaining in marketing sectors) during 2001-02. In per capita terms, the
annual availability of citrus fruits is nearly 12.5 kilograms of which
Kinnow makes up about 8 kilograms [Sharif (2004)].
About 94 percent of the citrus area is located in the Punjab
province. The area and production of citrus in Punjab have grown at the
rates of 5.6 percent and 4.7 percent per annum, respectively during
1980-81 to 1990-91. However, subsequently during the period 1991-92 to
2001-02, this pace could not be maintained. The growth rate fell to 1.08
percent and 1.06 percent per annum, respectively [Sharif (2004)], The
low level of growth in citrus production during the 1990s indicates that
the incentives for the farmers to increase production remained
depressed. This also implies that domestic citrus market is not
generating signals for encouraging investment in citrus production. It
is, therefore, imperative to examine the citrus marketing system in the
country along with the constraints faced by various stakeholders, the
underlying objective of the present study.
The specific objectives of the present study were:
* To identify the present citrus marketing channels and estimate
the margins of different market intermediaries;
* To identify the socio-economic and technical constraints to
citrus marketing functionaries; and
* To suggest recommendations for improvements in domestic marketing
systems.
II. REVIEW OF LITERATURE
Kohls and Uhl (1980) defined marketing as "The series of
activities involved in making available services and information which
influence the desired level of production relative to market
requirements, and the movement of product (or commodity) from the point
of its production to the point of final consumption". This includes
physical handling and transport, initial processing and packing to
simplify handling and reduce wastage, grading and quality control to
simplify sales transactions and meet different consumers'
requirements and holding over time to match concentrated harvest seasons
with the continuing demand of consumers.
Traditionally, market efficiency has been examined by applying the
correlation coefficient technique [see Lale (1971)]. But this approach
has been widely criticised on the grounds that a high correlation
coefficient between two markets does not necessarily mean that these
markets are well integrated in the sense that efficient performance of
traders prevails, which ensures that agricultural products move between
markets in a quick response to price differences that exceed transport
costs. Alexander and Wyeth (1992) pointed out that correlation
coefficient results would be misleading when the data include trends or
cycle, but these problems can be resolved by use of a detrended data
set. (1) Concerns about using correlation analysis with poor data sets,
however, are unavoidable no matter what technique is used [Khuskh
(1997)].
The review of literature revealed that like other developing
countries, in Pakistan, marketing functions are performed in a
traditional way and markets for agricultural products may not function
efficiently. There are generally great differences between prices paid
by consumer and those received by producers [Toaha (1974); Qureshi
(1974); Sattar, et al. (1976); Siddiqui (1977, 1979); Memon (1978); Khan (1980); and Mohy-ud-din (1991)]. On the other hand, very little research
has been done on domestic marketing of fruits and vegetables, therefore,
highly inadequate to guide the policy-makers. What so ever is available
is briefly summarised in Tables !. It is generally perceived that
marketing agents exploit producers and consumers by charging high
margins on their investment [All (2000)]. However, these perceptions
might be false because: (i) marketing margins in the off-season are
lower than margins in the peak season; (ii) price variability is
generally lower at the retail or wholesale level than at the farm gate;
(iii) negative correlation between prices paid by agents and marketing
margins implies that when agents pay higher prices, they have to reduce
their margin, mainly by reducing their profit. However, no rigorous
analysis is available on the rate of return on investment made by
marketing agents.
Regarding the marketing margins (Rs/kg) of different
intermediaries, producers earned a margin of 0.95-5.00, contractors as
1.55-8.75, commission agent as 0,09-1.37, wholesalers 0.82-2.5 and
retailers as 1.3-6.25. The lowest margins were in banana and highest for
mango. The lowest variation in marketing margins per unit quantity
handled was at producers' ends and highest at contractors. In case
of vegetables, the producers were found earning a margin (Rs/kg) of
3.06-14.02, commission agents as 0.28-0.82, wholesalers as 0.73-1.75 and
retailers as 1.06-2.93. The lowest margins were obtained in case of
onion and highest for tomato (Table 1). This may be attributed to the
element of high perishability in case of tomatoes.
III. METHODOLOGY
This paper is based on primary data collected from a survey of
citrus producers, market intermediaries and fruit markets in citrus
production and consumption areas. A purposive stratified random sampling
approach was used. Since the scope of the study is countrywide,
therefore, the universe becomes all the domestic markets of Pakistan.
Punjab, being the main producer of citrus fruit is the population of
this study. In Punjab citrus orchards are particularly located in
Sargodha, R. Y. Khan and T. T. Singh Districts. Being the largest citrus
growing district in the province and largest number of citrus exporters
located in Sargodha, this district was selected. Following the same
criteria, Sargodha and Bhalwal tehsils were further chosen for the
formal survey, Three villages were randomly chosen from selected
tehsils. Further, 10--12 citrus growers per village were randomly chosen
for interview. Contractors, commission agents and wholesalers dealing in
citrus and the retailers from different localities of the area were also
interviewed.
Before conducting the formal survey, a weeklong informal survey was
carried out for getting first hand information to prepare different sets
of questionnaires. This exercise provided an opportunity to understand
the existing production, marketing and export methods prevailing in the
study area. During the informal survey, the interviews were conducted
with group of producers, market intermediaries, and citrus exporters
etc. Based on this preliminary information sampling frames for each
category of sample respondents were prepared and questionnaires were
refined. Formal interviews were conducted with the following samples:
Producers 125; contractors 25; commission agents 20; wholesalers 44 and
retailers 41. Regarding group of the data, the contractors were grouped
into A, B and C types based on the investments made. The commission
agents, wholesalers, retailers were classified into less and more
experienced. Marketing margin analysis, deconstructing marketing margin,
profitability and market integration analyses were conducted to analyse the data. For details of these analyses, [see Sharif (2004)].
IV. RESULTS AND DISCUSSION
IV.1. Citrus Marketing System in Punjab
Citrus marketing system in Punjab contains marketing channels and
citrus contracting system. The brief description of both categories is
narrated below.
(a) Citrus Marketing Channels
Agricultural marketing channels are the routes followed by the
agricultural commodities before reaching in the hands of final
consumers. The Figure I depicts the existing citrus marketing channels
in a typical fruit-marketing scenario. The existing citrus marketing
channels have been identified and their contribution in citrus marketing
is briefly discussed as under.
Majority of citrus producers (95 percent) sold the harvesting
rights in their orchard at the flowering stage to the contractors. In
contracting business, there are no fixed criteria for entry and exit
into the business. However, contracting of citrus orchards is not an
easy job. The established contractors possess a wide knowledge in
orchard management and marketing practices. At the time of contracting
an orchard, several factors like age and health of the orchard,
flowering intensity, citrus variety, distance from metal road, road
quality, availability of transport facilities and transport cost
involved need to be contemplated. It was noticed that experienced
contractors more accurately estimate orchard output based on
appreciation of the natural environment and disease incidence. The
sample citrus contractors were having more than 13 years experience in
the business.
The commission agent is an important functionary in agricultural
marketing. All the sample fruit commission agents (local and other
markets of Pakistan) extended short-term loans to the contractors. With
the onset of harvesting season, the contractors start bringing the
produce for sale to them. The contractors do not receive all the sale
revenues from the commission agents as he is already under debt, rather
gradually settle the accounts. However, the commission agents do
provides some money to them to meet the expenses like second and third
installments for orchard owners, transport, payment to the labour and
packing material, etc. At the end of the season, the contractors finally
settle the season's account with the commission agents and become
eligible for making deals in the next season with the citrus producers.
Local and other country markets' commission agents found handling
51 percent and 40 percent of the total production, respectively (Figure
I). The sample commission agents had about 17 years of professional
experience.
[FIGURE 1 OMITTED]
The wholesaler usually purchases fruit from the commission agents
through open auction and sells to the retailers and consumers. After
purchasing the produce, he brings the produce on his yard where some
grading, standardisation, and cleaning is done. Local and other
provinces' wholesalers found handling 45 percent and 30 percent of
the total production. The sample commission agents had 13 years of
professional experience.
Two types of retailers (i.e., stallholders and hawkers) were found
in citrus marketing. Hawkers sell the fruit in baskets or hand pushed
carts and are usually mobile. The stallholders have shop in the consumer
markets, colonies and roadside markets etc. Both local and other country
market retailers bought 10 percent of the produce from commission agent
(Figure I). The sample retailers were having 12 years of professional
experience, Consumers of the citrus fruits are industrial buyers and
households. Industrial buyers include processing factories that purchase
from contractors directly from citrus orchards.
(b) Citrus Contracting System
As already discussed, most of the citrus output is mainly marketed
through contractors and majority of the citrus orchards have been
contracted soon after the fruit formation. Just after the fruit
formation completed, the contractors visit the area and make contract
with the orchard owners (both with whom they have business in the past
and new ones). The contract price is decided on the basis of age, health
and past performance of the orchard, availability of canal water, fruit
formation, variety, transport cost involved and the past dealing record
of both owner and contractor.
Finally, the producer also has his own rough estimates and its
value in the market. Citrus growers normally decide on a contract after
meeting 6 to 7 contractors. Majority (89 percent) of growers selected
the contractor who offered the highest price for their orchard and (42
percent) selected contractors who have a good reputation in respect of
timely payment. This provides evidence that both price and non-price
factor plays role in selecting a contractor. Many factors lead citrus
growers to contract out citrus harvesting rights. The most important
reason reported was lack of marketing knowledge. This needs to be
interpreted broadly. It was observed that commission agents do not
extend short-term loans to growers to enable them to manage their
orchard and to buy inputs and packing material in time, which is mainly
because majority of the pre-harvest contractors directly take output to
other markets of the country. The second most important reason reported
that commission agents do not want to transfer market price information
to producers and provide other facilities such as, accommodation and
telephone access at the market place. Therefore, producers have very
little information about the marketing of their produce, and face a
number of barriers to active participation in the process. The third
reason reported by the growers is that they are growing other crops, at
the time of harvesting of citrus. The sowing and harvesting operations
of other rabi and kharif crops entail enough of their time, therefore,
they do not have much time to manage all these activities, and prefer to
sell an orchard to a contractor. Only 10 percent of citrus growers
reported urgent cash needs as a reason to contract the orchard (Table
2).
IV.2. Marking Marginal Analysis
The marketing margin analysis revealed that overall citrus prices
at retail level are almost three times higher than what is received by
the producer. The major jumps in citrus prices were observed from
producer to contractor and from wholesaler to retailer (Table 3). The
earlier intermediary brings produce from farm to market and later
carries it from market to at/near the door-step of the consumer.
(i) Absolute Cash Margin Analysis
The absolute cash margin analysis shows that contractors receive
the largest margin (89 percent) (Table 3). This may be because they bear
the highest costs and most risk among all marketing agencies.
Contractors lease the citrus orchards at the time of flowering. If we
consider the risk factors like high product variation, bad weather,
insect attack and disease incidence, high transport costs, output
spoilage during transportation, then this margin may not be very high.
The losses occurred at farm as 9 percent, contractor as 5.35 percent
(i.e. picking 3 percent, packing 2 percent, and transportation 0.35
percent) [Sharif (2004)]. The second intermediary earning highest profit
(25 percent of purchase price) is the retailer. The retailer normally
buys a quantity easily disposed in one day. The investment is relatively
low but there is a risk that it may be impossible to sell the whole
quantity. The retailer also has no proper opportunity to ascertain the
quality, quantity, size, and colour of layers filled in the crates by
the wholesaler. The absolute cash margins of all intermediaries found
increasing as the citrus production season proceeds towards its end.
(ii) Share in Consumer's Rupee
In this analysis, the consumer's one rupee expenditure on a
particular commodity is divided between the producer and other marketing
agencies in percentage terms. Overall, the producers' share was 35
percent followed by contractors and retailers obtaining 32 percent and
20 percent, respectively. The producers' share in early season was
estimated as 44 percent and 27 percent at the end of the season. The
percent share of commission agents and wholesalers was also declining.
For the rest of the intermediaries, it was increasing towards the end of
the season. The percent share of retailers in consumer rupee was more
than double during late season than the mid-season (Table 4). This is
perhaps because of high probability of quality deterioration due to high
temperature in late season particularly. The results are similar to the
results reported by Khushk and Smith (I 996) in mango marketing in Sindh
province of Pakistan.
(iii) Marketing Costs
The marketing costs using the actual expenses incurred were
computed at each stage of the marketing chain. Overall, the marketing
costs of the contractors were the highest and of commission agents as
the lowest (Table 5).
The researcher in collecting the marketing costs from the market
agencies encountered a few problems. These problems are: (a) lack of
available written records with the growers and other market
intermediaries. If available, it was out of reach from the research
workers. Therefore, crosschecking was applied in order to reduce the
margin of error; (b) the respondents were hesitant answering many
questions related to costs and profit margins in their business. Hence,
it involved a lot of time and effort on the part of the research worker
to gain a fair degree of confidence of respondents and hence to obtain
from them the required information.
(iv) Profit Margins
A further indicator calculated is the percentage profit margin
defined for each intermediary as the net profit margin divided by the
absolute cash margin expressed as a percentage. The absolute cash margin
was already calculated by subtracting the price paid by a specific agent
from the price received by the same agency. The estimated percentage
profit margins of each marketing intermediary are presented in (Table
6). The grower received highest profit margin (71 percent) followed by
retailer (62 percent). The other marketing agencies including
contractors, commission agents and wholesalers received 38 percent, 44
percent and 47 percent respectively. Assessment of whether or not the
values found for the indicators presented here show that citrus
marketing system is fair and efficient is difficult to judge.
IV.3. Deconstructing Marketing Margin Analysis
The purpose of deconstructing marketing margin is to know what
component of marketing activity is important or absorbing the greater
share of consumer rupee (Table 7). It was found that at contractor
level, the profit margin, marketing costs and transport costs are the
major elements of the gross margin earned. At commission agent level,
expenses on business management and profit are major components. At
wholesaler level, the profit margin and material cost constitute major
part of the price difference. At retailer level, the profit margin,
opportunity value of labour and transport cost are the main elements in
the distribution of gross margins earned. It can be concluded that the
highest profit margins are fixed/earned by the contractors and
retailers. Their transport expenditures are also very high.
It can be concluded that (i) profit absorbed most of the marketing
margin; (ii) retailers receives the highest gross returns and rate of
return are highest in comparison with other marketing agents; (iii) the
highest rate of wastage occurs at the level of contractor. Efforts are
required to control the post harvest losses through making improvements
in packing material.
IV.4. Profitability Analysis
The profitability analysis is carried out for different market
intermediaries and presented in the following subsections.
(i) Profitability of Citrus Contractors
The summary of contractors' costs indicates that the net
profits of "A" type contractors are considerably higher than
of "B" and "C" types. (2) "A" type
contractors have higher market share due to large capital investment,
strong bargaining position and low operating costs. Comparable with the
one available example from literature in Pakistan, the returns earn by
mango contractors appear quite high, but not exceptionally high as
fairly high level of risks are also involved. An average Return On
Capital Employed (ROCE) was 16 percent for nine months, or 1.78 percent
per month, also appears attractive compared to interest earn on bank
deposit accounts, currently within the range of 12-14 percent per annum
in Pakistan. The results indicate that on average, citrus contractors
earned about Rs 50,000/month (Table 8), which is reasonably good for the
services provided.
(ii) Profitability of Commission Agents
Overall the ROCE was higher than the rate estimated for the
contractors. It was found that net profit is directly associated with
the duration of experience, This implies that more experienced
commission agent perform business in a highly profitable manner as
compared with their counterpart as their ROCE was 23 percent higher
(Table 9). Compared to other studies, Sial and Anjum (1990) found that
returns to capital for commission agents ranged between 64 percent and
104 percent in Rawalpindi market. They concluded that commission agent
is the most established intermediary in the marketing chain.
(iii) Profitability of Wholesalers
Their profit margin varies with the quality of the fruit and price
prevailing. Overall the return on capital employed was estimated as 86
percent, in early and late seasons, the amount of profit per kg is
relatively higher as compared with the midseason. It was found that the
operational costs of wholesalers are relatively higher as compared with
other market intermediaries. This is mainly because the volume of
business involved is relatively smaller in size and they also have to
face some losses due to commodity deterioration. The more experienced
wholesalers were earning relatively higher profit (Table 10).
(iv) Profitability of Retailers
It was found that retailers had lower variable costs than the
wholesalers and commission agents, The returns on capital invested were
highest for retailers than all market intermediaries. Like wholesalers
and commission agents, the percent returns on capital found positively
associated with the duration of professional experience. It was also
found that except their own labour, they hardly employ any other labour
for assistance in business activities (Table 11).
IV.5. Market Integration Analysis
To assess the market efficiency, analysis of correlation
coefficient of wholesale prices of citrus in the selected markets of
Punjab has been carried out. Initially, an autoregressive process has
been used to see the dynamic process of price changes in two spatially
separated markets, then, first differences of logarithms of raw price
data are undertaken. After that log price data were smoothed and
difference smoothed because, this offers an immediate interpretation of
the data, In this analysis only one lag has been used, because one lag
is sufficient to understand the behaviour of price changes in the
markets. Then we look at the coefficients of the autoregressive process
to understand how price changes in one market are related to the price
changes in another market.
The correlation coefficients of citrus price level (raw and
smoothed) and price difference (raw) of selected markets of Punjab under
study are presented in (Table 12). The correlation coefficients of price
level are quite high, for the inter- and intra-market relationship.
According to the rating system proposed by Kinnear and Taylor (1987),
correlation values of r>0.80 indicate that there is a strong degree
of association of price between markets (3); if r is <0.80 and
>0.05, price relationship between markets is moderate to strong; and
if r is below 0.4; the price relationship between markets is week. The
correlation coefficients are tested for significance with the help of
t-tests. The results of correlation coefficients based on price from
citrus producing markets are integrated and prices are completely
transmitted from source market to citrus consumption markets.
Alternatively, results for the second measure based on price
difference (smooth) indicate that citrus markets are partially
integrated and price changes in citrus producing market are not fully
and immediately transmitted to citrus consumption markets of the country
but correlation coefficients are still greater than 0.8, meaning they
are still fully integrated.
(i) Market Integration Tests
The conclusion based on correlation coefficient of price level
alone will be misleading therefore, more advanced integration tests have
been carried out, which has the ability to explore various aspects of
the price movement between the regional markets. As mentioned earlier
correlation coefficient analysis itself is not sufficient to conclude
that markets are integrated. Further investigation is needed to assess
the market integration in Pakistan. The performance of various markets
of Punjab in relation to Sargodha market was tested and reported in
Table 13. This model suggests that prices at Lahore, Faisalabad and
Multan would change as price at Sargodha market changes. The coefficient [[beta].sub.1] would measure the degree of integration between two
markets; [[beta].sub.1] would be equal to 1 if the two markets were
fully integrated (or the two markets would be fully integrated if
[[beta].sub.1]-1=0); and the value of [[beta].sub.1] between 0 and 1
implies that markets are partially integrated. The fully integrated
markets would suggest that markets were performing well as the changes
in the prices in the base market were fully transmitted to other markets
as was required under perfect competition. A partially integrated market
suggests that price changes in one market do not fully transmit to the
other market because of imperfection between the two markets. Please
note that the intercept would be positive and would represent the
transshipment cost. The coefficient [[beta].sub.0] would measure the
change in the transshipment cost during the difference period
considered. The positive value of [[beta].sub.0] implies that
transshipment cost increased during the lagged period.
Considering the integration of Sargodha-Faisalahad markets, the
null hypothesis that intercept term is equal to zero is rejected which
indicates that there have been changes in the transshipment cost between
Sargodha and Faisalabad markets even on weekly basis. On the other hand,
the null hypothesis that the coefficient of variable [DELTA]Ps is equal
to unity is rejected implying that both markets are partially
integrated.
Taking up the case of integration between Sargodha and Lahore
markets, the null hypothesis that intercept term is equal to zero is
rejected which indicates that there have been changes in the
transshipment cost between Sargodha and Lahore markets even on weekly
basis. On the other hand, the null hypothesis that the coefficient of
variable [DELTA][P.sub.s] is equal to unity is rejected implying that
both markets are partially integrated.
Regarding the integration of Sargodha-Multan markets, the null
hypothesis that intercept term is equal to zero is rejected which
indicates that there have been changes in the transshipment cost between
Sargodha and Multan markets even on weekly basis. On the other hand, the
null hypothesis that the coefficient of variable [DELTA][P.sub.s] is
equal to unity is accepted implying that both markets are fully
integrated.
IV.6. Socioeconomic and Technical Constraints to Citrus Marketing
It is observed that most of the contractors have no information
about trade situation in various markets. They either relies on the
traditional sources like fellow contractors or the prices told to them
by the commission agents of various markets on telephone. Such
information is always partial and sketchy. In citrus, pricing mechanism
depends upon the time, type and location of the market under
consideration. The producers have no information about prices in markets
other than their local market. For the prices, contractors totally rely
on their lending commission agents. During auction, since very little
grading (4) has been made by the contractor before presenting the output
in the market for auction, therefore, the level of auction price
received depend upon the proportions of best and worst quality fruit (in
terms of freshness, size and appearance) present in the lot. Hence, the
lack of finance is one of the major constraints on the part of the
producers and contractors.
Secondly, in the marketing chain the deconstruction of marketing
margin analysis revealed that retailers are receiving highest gross
returns and the returns on capital invested are also highest in
comparison with other marketing agents. This is mainly attributed to the
grading performed by him before selling to the consumers. His percent
profit margin is also considerably increases in the late season because
the proportion of good quality mature fruit in the purchased lot
increases during late season, although prices are also high during this
period.
Thirdly, the supply of citrus (Kinnow) is relatively high in the
months of January-February. The cold store facilities are least used in
domestic citrus marketing because cold weather is prevailing during
these months. The contractors try to obtain higher prices by delayed
plucking of fruit while on the other hand, this late plucking affects
flowering for the following season. On the other hand, producers are
interested in vacating their orchard as soon as possible. This creates
clashes of interests between producers and contractors. The lack of cold
store facilities also an underlying cause of high post harvest losses at
contractor level as incidence of frost and some other disease may result
huge financial loss. In the study area, the cold storage facilities for
citrus fruits are only available with the citrus processing factories,
which use it for chilling purposes before shipping it for export.
V. CONCLUSIONS AND RECOMMENDATIONS
in citrus, the duration of contract is almost one year. More than
90 percent citrus producers sold harvesting rights of their orchards to
contracts. The producer share in consumer rupee was 35 percent, tbllowed
by contractor as 32 percent and retailers as 20 percent. The
deconstructing marketing margin analysis shows that profit absorbed most
of the marketing margin. The estimates on the returns to capital
invested (ROCE) came to be 16 percent for contractors, 82 percent for
commission agents, 86 percent for wholesalers, and 164 percent for
retailers, in this way, retailers received the highest gross return and
rate of return was highest than other marketing agents. The highest rate
of wastage occurs at the level of contractors. The market integration
analysis using the weekly price data for last two decades shows that
Sargodha market is relatively better integrated with Faisalabad and
Lahore than Multan as the coefficient for price at source market was
greater than unity. However, the statistical test of integration
revealed that the Lahore and Faisalabad markets are poorly integrated
with Sargodha.
(i) Potential for Improvement in Domestic Citrus Marketing
From the analysis of domestic citrus marketing and the problems
faced by various market intermediaries, it is clear that the major
obstacle in the smooth functioning of domestic marketing process is the
lack of practicing grading and standardisation. Due to lack of this
grading and standardisation, various intermediaries are getting more
than their due margins. The undue share is because of monopoly in the
market by commission agent, and small scale of market retailers are
operating with him. The improvements in the marketing infrastructure
(e.g. roads, availability of transport and cold stores, uniform
standardised grades etc.) will make the marketing of citrus more
competitive by ensuring due shares of the intermediaries for the
services rendered.
The contractors also have some clash of interest. For example,
contractors will not invest on land improvement because it will generate
benefits in the long run when he might not be there. This signifies the
need for educating citrus contractors on management practices, so that
no friction should arise in their relations with the orchard owners.
This will lead to joint effort in increasing productivity and quality of
the output produced. Another underlying reason is the lack of
competition among commission agents. The commission agents are sitting
in the markets since ages. This is because few new fruits and vegetable
markets are opened in the country over the past three decades. These
commission agents have their own contractors with whom they perform
business by extending informal loan to them for booking the orchard with
the producer. In this way, the commission agents can have crude idea
about the volume of business that would definitely take place through
them.
(ii) Recommendations
After summarising the findings and discussing the potentials for
improvement, it seems appropriate to suggest various recommendations for
the overall development of citrus marketing in the country.
* Efforts are required to control post harvest losses through
making improvement in packing material during citrus marketing and
provision of incentives for establishing cold stores in the area.
* The financial institutions are desired to reformulate the laws
and regulations to ease out the loaning process in order to alleviate the financial constraints of producers particularly.
* The Department of Agricultural and Livestock Products Marketing
and Grading (DALPMG) is suggested to disseminate the marketing related
information to all stakeholders in more effective manner by establishing
an MIS.
Comments
The study on "Domestic Citrus Marketing System: Constraints
and Potential for Improvement" is an effort towards searching ways
for increasing net income of farmers and decreasing per unit cost. It
synchronizes with the advice of various agricultural experts who, in the
light of AoA's of WTO, have been advocating for the last several
years, for becoming efficient in order to compete in the international
markets. Citrus is the largest grown fruit Pakistan with annual market
value over Rs 10 billion. Thirst of the study is on marketing channels;
marketing margins and some socio-economic and technical constraints in
marketing of citrus fruit.
The study was directed in the citrus growing area of Punjab. Sample
size of 125 respondents is large enough to draw logical conclusion.
Results of the study indicate that in case citrus, growers are
being robed by marketing intermediaries. Farmers share in consumer
rupees is only 35 percent.
The study has not explicitly mentioned the universe of the study
and description of the universe also need elaboration so that readers
can better appreciate the results of the study in the backdrop of the
universe of the study. The study is silent about the review of
literature. In the past several studies have been taken with similar
objectives on fruits and vegetables. Their results are more less in the
same range. Authors need to clearly pinpoint if there is anything new in
their methodology.
The study has given the sample size but sampling procedure and
sampling design are missing. Authors may like to add a few more
sentences about this.
The study has rightly pointed out that marketing intermediaries are
getting the lion's share from farmer's earning. The same has
been pointed out times gain by various studies over the past four
decades but market intermediaries are still lingering on. In fact, they
are also playing some use role, e.g. providing of credit facilities,
logistic facilities and bearing of risks. If we realy want to displace them we need create viable alternative arrangements.
The title of the study--Marketing System is very broad but the
objectives have been narrowed down to a couple of points. Marketing
system also covers storage, packing and packages, grading, transporting
and marketing intelligence, etc. These have not been touched in the
study, Authors may like to refine their title in light of objectives of
the study.
On the whole the study has been directed towards a crucial
researchable issue, It is rich and comprehensive. Methodology is good,

(1) When detrended approach is used, testing stationarity of a
variable is necessary, which can be done with the help of a unit root
test [Charemza and Deadman (1993)].
(2) Contractors having contracts higher than Rs 2 million were
classified as A type contractors, those having contracts below Rs 1
million were put under category C, and the remaining ones were placed in
category B.
(3) For example, a high and significant correlation coefficient of
0.9 (r = 0.9) indicates that 0.9 percent [why 0.81 when the coefficient
is 0.9] of price variation in one market is associated with price
variation in another market.
(4) The export quality citrus fruits are usually separated and
supplied to Kinnow processing factories in the area, however, no
reliable evidence was available on the proportion of such fruit is taken
out before shipping to domestic markets.
