A Temporal Analysis of Growth in Fertilizer Consumption vis-àvis Food Grain Production in Rajasthan, India

The present investigation pertaining to the growth of fertilizer consumption and food grains production in Rajasthan was conducted during 2017-18. This study was based on time series data, which was collected from 1967–68 to 2014–15. The results of the present investigation revealed an increasing trend in fertilizer consumption and food grains production from 1967-68 to 2014-15 in Rajasthan. Total fertilizer consumption in Rajasthan significantly increased at the rate of 13.82 percent per annum during the post-green revolution phase-I. The consumption of N significantly grew by 14.26 percent per annum, that of P and K increased by 12.24 percent and 12.71 percent, respectively. Food grains production also increased by 2.41 percent per annum. In the post-green revolution phase-II, a growth rate of total fertilizer consumption increased at the rate of 9.96 percent, N significantly grew by 7.88 percent, P increased by 17.09 percent; whereas, K decreased by 0.94 percent per annum. However, food grains production was increased by 1.57 percent per annum. The analysis of post-reform period pointed out that the total consumption of composite fertilizers, N, P, and K significantly increased at the rate of 4.49 percent, 4.32 percent, 4.79 percent, and 7.21 percent, respectively. Food grains production also registered a significant growth rate of 3.71 percent per annum. In the entire period of study (1967–68 to 2014–15), total consumption of fertilizers had increased at the rate of 8.35 percent per annum. While the consumption of N grew by 8.08 percent per annum, that of P and K increased by 9.60 percent and 4.95 percent, respectively. Food grains production was increased by 2.78 percent per annum.
