ABSTRACT
A field experiment of hedgerow intercropping of pigeonpea with rice and mungbean followed by blackgram and groundnut, respectively, as alley crops was conducted to determine the effect of hedgerow crop on the yield of alley crops, the productivity of hedgerow crop and its contribution to the alley crops. Alley cropping of rice-blackgram and mungbean-groundnut crop sequences with 1.5 and 2.5 m hedgerow distance of pigeonpea along with sole cropping sequences were evaluated. Grain yield of all crops were affected by hedgerow intercropping systems. Significantly highest rice equivalent yields and gross returns were obtained by hedgerow intercropping systems with 2.5 m hedgerow distance for both the crop sequences in both 1995 and 1996. The highest gross margin and the highest benefit-cost ratio (BCR) were resulted from hedgerow intercropping at 2.5 m distance with rice-blackgram crop sequence and the system was found profitable.
