Effect of different nutrient management practices in rice (Oryza sativa L.) -blackgram (Vigna mungo L.) utera cropping sequence

摘要

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 'P_2O_5' 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.
