The effect of different nutrient management practices on the performance of both rice and blackgram crop grown in rice-blackgram utera cropping sequence was studied in an on-farm trial carried out in five different villages of Tangi block in the Khurda district of Orissa during three consecutive crop growing season of 2001-02, 2002-03 and 2003-04. The highest grain yield (38.4 q ha^-1) of rice as well as the highest seed yield (5.87 q ha^-1) of blackgram was recorded in the treatment where additional 20 kg ‘P₂O₅’ of blackgram was applied to rice as basal along with the recommended dose of fertilizer. The highest net return (Rs. 15,618) and benefit : cost ratio (2.28) were also recorded from the same treatment plots.
