In Telangana, nineteen FLDs were conducted in maize crop with target yield of 60q/ha to popularize the use of fertilizers through STCR fertilizer prescription equation. The mean initial nutrient status in these locations was 177 kg N, 53 kg P2O5 and 288 kg K2O ha-1. On an average, the fertilizer requirement based on STCR approach for this crop was found to be 161 kg N, 65 kg P2O5 and 74 kg K2O/ha. Use of fertilizer prescription equation for maize based on soil test indicated that an amount of N, P2O5 and K2O in the range of 111 to 212, 43 to 98 and 31 to 114 kg ha-1 to be used by farmers to achieve 60 q of maize /ha. However, the farmers realized yield in the range of 50 to 60 in these locations with a mean 56 q/ha due to soil test based fertilizer use. The mean economic gain variation due to change in fertilizer use and yield between use of STCR equation and farmers own method worked out to be Rs 5,885/ha.
