摘要：Chemical fertilizers have played a vital role in the success of India's green revolution and consequent self-reliance in food-grain production. Fertiliser consumption in India has been increasing over the years and today India is one of the largest producers and consumers of fertilisers in the world. The analysis of growth is usually used in economic studies to find out the trend of a particular variable over a period of time. The necessary secondary data about consumption of NPK in Karnataka were collected from Directorate of Economics and Statistics, Karnataka for the year 1989-90 to 2015-16 and was estimated using the compound annual growth rate function. The results of CAGR (Compound Annual Growth Rates) in consumption of nitrogen fertilizer revealed that the consumption of NPK (Nitrogen-Phosphorus-Potassium) fertilizer witnessed significant growth during period-I (1989-90 to 1996-97) compared to period-II (1997-98 to 2009-10) and period-III (2010-11 to 2015-16). In the overall period, the growth in consumption of NPK fertilizer from 1989-90 to 2015-16 was noticed positive across all the divisions which were highest annum in Kalburagi division (24.74%) followed by Belagavi (24.50%), Mysuru (21.32%) and Bengaluru (20.53%). Higher growth was noticed in the Kalburagi division and has less variability as compared to other divisions.
