TREND OF FERTILIZER CONSUMPTION IN TELANGANA
AbstractOver the last three decades, N, P, K and total NPK and its per hectare consumption in Telangana observed an increasing trend. The absolute NPK consumption was increased by 4.6 times while per hectare consumption was increased by 4.3 times. The NPK per hectare consumption was 51 kg/ha during 1985-86 which increased to 221 kg/ha during 2014-15. The per hectare nitrogen consumption was more compared to phosphorous and potassic fertilizers during the study period. The CAGR of total NPK consumption was 5.25 per cent for the period of 30 years (1985-2015). The coefficient of variation of per hectare consumption of total NPK consumption was 36.58 per cent for the study period. The CAGR and coefficient of variation in consumption of K overtime was more than N and P. The ratio of per hectare consumption of N: P: K was 9:4:1 and 10:3:1 during 1985-86 and 2014-15 respectively. The per hectare fertilizer consumption in Telangana has deviated from the recommended doses for efficient use of fertilizer.
