Abstract

In this paper, observations on sorghum (Sorghum bicolor)/pigeon pea (Cajanus cajan) and pearl millet (Pennisetum typhoides)/groundnut (Arachis hypogaea) intercrop systems are highlighted, with particular reference to weed growth as affected by a few selected biophysical factors. With increase in density of a sorghum/pigeon pea system, there was a rapid decrease in weed dry weights. The inclusion of additional "smother" crops like cowpea (Vigna unguiculata) and mung bean (V. radiata) minimized weed infestation. These crops could replace 1 hand weeding without affecting the main crop yields. In the pearl millet/groundnut system, the row arrangement of 1 pearl millet with 3 groundnuts resulted in optimum weed supression and maximum intercrop advantage
