Field experiments were conducted during rainy seasons of 1987 to 1989 at Regional Agricultural Research Station, Palem to determine the cost effective and economic integrated weed management in pigeonpea-groundnut intercropping system. The results revealed that less weed mass, higher yields of pigeonpea grain and groundnut pods, betterweed control efficiency and higher returns were obtained in weed management system involving hand weeding twice (15 and 30 DAS) followed by hand hoeing (30 and 42 DAS). The next best treatments were pendimethalin 1.0 kg/ha and f1uchloralin 1.0 kg/ha each followed by hand hoeings.(30 and 42 DAS).
