Open publisher page 3 citations

Abstract

An experiment was conducted to find out grain yield and nitrogen uptake by hybrid rice under different planting dates and N levels during 2007 and 2008. The hybrid rice planted on July 1 or July 15 had significantly higher grain yield and N uptake. Delayed planting between August 1 and August 16 significantly reduced the grain yield to the extent of 21.1% and 36.4%, respectively compared with planting of July 1. Number of effective tillers, grains panicle−1, test weight, grain yield, N concentration and uptake by grain and straw increased significantly with increasing levels of N from 60 to 120kg ha−1.
