Abstract:

To develop fertilizer prescription equation for rice, a field experiment was conducted on an inceptisol of farmer’s field at Arachikuppam village, Puducherry during 2015 by using integrated plant nutrient management system on the basis of STCR approach. The rice grain and straw yield was significantly increased with the soil test values and fertilizer doses of N, P and K. Based on the experiment, the nutrient requirement for producing 1 quintal of rice grain was 1.46 kg of N, 0.60 kg of P2O5 and 1.12 kg of K2O, respectively. The percent nutrient contribution from soil was 20.18, 21.39 and 19.52, from fertilizer 39.04, 39.39 and 70.97 and from organic manure 23.06, 30.40 and 55.03 for N, P2O5 and K2O respectively. By using the basic parameters the soil test based fertilizer adjustment equations for specific targets of rice grain yield of 7.0 and 8.0 t ha-1 have been calibrated based on the targeted yield concept. These fertilizer prescription equations developed for Rice (var.) White Ponni can be used to estimate fertilizer doses formulated for the range of soil test values and desired yield targets under NPK alone and IPNS ( NPK plus FYM).
