Effect of integrated nutrient management on productivity, nutrient uptake and economics of rainfed pigeonpea (Cajanus cajan) and blackgram (Vigna mungo) intercropping system

TL;DRAbstract

Field experiments were carried out during kharif season of 2008-09 and 2009-10 to study the effect of integrated nutrition on productivity, nutrient uptake and economics of rainfed pigeonpea [Cajanus cajan (L.) Millsp.] and blackgram [Vigna mungo (L.) Hepper] intercropping system. Pooled data shows that intercropping systems did not influence significantly on the grain, stover, biological yield and harvest index of pigeonpea and blackgram. Total uptake of N, P, K, S and Zn by pigeonpea were highest recorded with the sole pigeonpea (S1) which was comparable to normal intercropping system (S2) and significantly superior over paired intercropping system (S3). Further, pooled data revealed that normal intercropping system (S2) gave maximum values of gross return (Rupees 120 050), net return (Rupees 99 396), B:C ratio (4.8), pigeonpea equivalent yield (21.75 q/ha), land equivalent ratio (1.70), production efficiency (7.98 kg/ha/day) and economic efficiency (364.83 Rupees/ha/day) which was a
