A field experiment was conducted at the Division of Agronomy, Indian Agricultural Research Institute, New Delhi during 1983‐84 and 1984‐85 to study the effect of lentil residues on the yield and response of succeeding rice to nitrogen. Lentil residues benefitted the succeeding rice and gave longer and heavier panicles, more grains per panicle, higher 1000‐grain weight and higher grain and straw yield of rice as compared to fallow. Rice responded well to applied nitrogen both in the absence and presence of lentil residues. The effect of lentil root residues and root residues plus incorporation of lentil straw was equivalent to 11 and 33 kg N ha −1 when 60 kg N ha −1 was applied to rice; the corresponding values being 54 and 60 kg N ha −1 when 120 kg N ha −1 was applied to rice.
