摘要：The study was undertaken to determine the production of Brinjal and to compare the financial profitability between IPM and Non-IPM Brinjal growers in the study areas. The study areas covered two intensive vegetables growing districts namely Comilla and Narsinghdi. The sample was 100 farmers taking 50 from each district. Among the farmers, 50% considered as pesticide users and 50% IPM users. Apart from descriptive statistics, Probit regression model and Cobb-Douglas production function was used in order to analyze the data. The findings of the study suggested that cost of brinjal production was higher for Non IPM farmers compared to IPM farmers. The average yield for the IPM and non-IPM farmers was found 38.7 ton per hectare and 45.9 ton per hectare respectively. Findings also suggested that IPM farmers had cost advantage compared to Non IPM farmers in the study areas. Among the explanatory variables of probit regression, coefficient of experience was found positive and significant while coefficient of distance to market and family size were negative and significant. Cobb-Douglas production function analysis suggested that the coefficient of human labour and cowdung had positive and significant effect on the yield of Brinjal. On the other hand irrigation and fertilizer had negative effect on the yield. This may be due to the fact that farmers may over using the irrigation and fertilizer in the Brinjal field. Lack of technical knowledge and effectiveness of pheromone trap for all insects was the major drawback for IPM adoption. The study recommends undertaking more training and research activities to overcome the problems of IPM technology for Brinjal.
