Abstract
Intercropping pigeon pea with various other crops reduced weed growth by 75%. The crop-weed balance in the intercrop system was influenced by many factors such as crop species and variety, plant population, crop geometry, soil types and herbicides. Among the various intercrops maize, cowpea [Vigna unguiculata] and pearl millet [Pennisetum americanum] showed an initial weed-smothering effect while groundnut was effective at later stages of crop growth. Weed growth in the compact type of pigeon pea (HY3A) was substantially higher than in the spreading type (ST1). Within the intercrop system, row arrangement did not influence weed infestation but the increase in population pressure resulted in considerable decreases in weed DM weights. Among the different herbicides evaluated in various systems, alachlor at 1 kg/ha in maize + pigeon pea caused initial toxicity to pigeon pea while prometryne, terbutryne and ametryne proved promising in sorghum + pigeon pea.
