Abstract

A study was under taken to evaluate the response of maize + legume intercropping system (I.C.S.) under additive series to different weed control practices. Soybean, blackgram and greengram were used as intercrops with weed control methods viz., pre-emergence (PE), pendimethalin and alachlor each @ 1.0 kg/ha, hand weeding at 20 DAS. Blackgram and greengram as inter crops reduced the weed density and weed dry matter. Alachlor recorded higher weed control efficiency. Introduction of different rainy season legumes did not affect the yield attributes and yield of maize but significantly increased maize equivalent yield. All weed control treatments resulted in significant enhancement in maize yield attributes and yield. Weed control through alachlor @ 1.0 kg/ha recorded higher maize equivalent yield. Higher net returns and benefit: cost ratio were obtained in maize + greengram intercropping system
