Abstract

Field experiments were conducted for two consecutive rabi seasons of 2009 & 2010 in seven randomly selected farmer's fields covering both East and West Godavari Districts of Andhra Pradesh to compare the performance of System of Rice Intensification (SRI) over recommended practice and farmers practice of transplanted rice. The results revealed that SRI practice proved to be superior over the recommended practice as well as traditional farmers practice. SRI matures early by 3-4 days with higher tiller to panicle conversion ratio (83.1%), higher spikelet fertility (82.9%), panicle weight, grain yield (6.95 to7.34 t ha-1),straw yield and gross returns with 21.5 to 26.1% water saving, respectively, in both the years of experimentation.
