Abstract: A field experiment was carried out during kharif 2014 at Research Farm of Tirhut College of Agriculture, RPCAU, Pusa, Bihar to study the effect of summer legumes on yield and nutrient uptake of succeeding direct-seeded rice (Oryza sativa L.) under different nitrogen levels. Rice crop sown after incorporation of dhaincha recorded significantly higher grain, straw yields and nutrient uptake than crop seeded after mungbean, urdbean and fallow. Grain and straw yields increased significantly with increasing levels of nitrogen but significantly increase was recorded only upto 100% RDN further increase in nitrogen levels fail to produce significant effect on grain and straw yields. Application of 150% RDN recorded significant increase in nutrient uptake by rice crop than lower levels of nitrogen.
