Abstract

Different fertilizer treatments were applied to local rice varieties under SRI (system of rice intensification) against conventional management practices at ARI Mingora Swat during 2010-2011 using RCBD with split plot arrangement. The results show that under the SRI practices, rice varieties performed well and the plant parameters such as number of panicles plant-1, number of tillers plant-1, plant height, panicle length, grains panicle-1, biological yield, grain yield, harvest index, 1000-grain weight and plant dry weight were significantly improved under the SRI method as compared to traditional method. Combined fertilizers (NPK and Zn) enhanced rice yield significantly, which can be attributed to positive effect on yield components. Rice variety, Fakhre Malakand out performed under SRI management practices with combined application of fertilizers. It was concluded that SRI is the best management practice for rice cultivation as water availability is most likely to be a major constraint in the immediate future.
