ABSTRACT

An experiment on intercropping of potato, bushbean and edible poded pea with wheat at different row ratios was conducted in the irrigated upland ecosystem to study the agronomic and economic productivity and advantages of intercropping as compared to sole cropping. Intercropping of potato with wheat at 2:5 row ratio gave significantly higher wheat equivalent yield (WEY), higher land equivalent ratio (LER), higher gross return and benefit cost ratio followed by the same intercropping at 3:8 row ratio. On the other hand, competitive ratio was lower when potato was intercropped with wheat at the 3:8 row ratio followed by the same intercropping at 2:5 ratio. On an average intercropping of potato with wheat at 2:5 row ratio indicated the advantage of intercropping than those of other tested crops at different row ratios and sole cropping.
