Abstract

A field trial was conducted for the two Kharif seasons of 1969 and 1970 to study. the nutritional requirement of two rice varioties-1. R. 8 and Jaya under 3 levels of nitrogen (100, 200 and 300 kg N/ha) and 3 levels of phosphorus (50, 100 and 150 kg P₂Os/ha). The result indicated that rates of nitrogen and phosphorus influenced the grain yield signifi- cantly, during both years. The rice variety Jaya outyielded I. R. 8 significantly. The highest yield was recorded with the application of 211.64 kg N/ha whereas the optimum dose was worked out to 166.83 Kg N/ha, Application of phosphorus varying from 50 to 100 kg POs/ha improved the grain yield significantly,
