Effect of summer legumes on growth and yield of succeeding direct-seeded rice (Oryza sativa L.) under different nitrogen levels

Abstract

A field experiment was conducted at Research Farm of Tirhut College of Agriculture, RPCAU, Pusa, Bihar during kharif 2014 to assess the effect of summer legumes on growth and yield of succeeding direct-seeded rice (Oryza sativa L.) under different nitrogen levels.Rice sown after incorporation of dhaincha recorded significantly higher plant height and yield indices i. e. number of tillers, and panicle m-2, length of panicle and grains panicle-1 than crop sown after fallow. However, grain and straw yields were significantly higher when rice was seeded after dhaincha than crop seeded after mungbean, urdbean and fallow. Plant height, yield indices, garin and straw yields increased significantly with increasinglevels of nitrogen but significantly increase was recorded only upto 100% RDF further increase in nitrogen levels fail to produce significant effect on these parameters. The crop seeded after incorporation of green manure crops recorded significantly higher grain yield upto RDF. However, crop seeded after fallow recorded significantly higher grain yield upto 150% RDF.
