Abstract
Abstract Short duration legumes such as cowpea (Vigna unguiculata) urdbean (Vigna mungo) and mungbean (Vigna radiata) intercropped with pigeonpea suppressed weed flora by 20–45% over sole pigeonpea (unweeded check) and proved more productive under rainfed conditions. Intercropping under uniform row planting pattern (pigeonpea rows at 60 cm with one row of intercrop in between) was more efficient in weed suppression as well as in total productivity compared with paired row planting at 40/80 cm distance. Unchecked weeds caused yield loss of 678 kg/ha in sole pigeonpea which was compensated by intercroppping mungbean. This postulates that one can overlook weed control in rainfed pigeonpea without any economical loss if mungbean is intercropped. This information is of immense significance in view of high cost of weed control measures.
