AbstractThis study examined the effects of alley cropping of Acacia senegal (L.) Willd. on growth and yield of groundnut (Arachis hypogaea L.), millet [Pennisetum glaucum (L.) R. Br.], and sesame (Sesamum indicum L.). The field experiments were conducted in North and South Kordofan, Sudan, in a 15-year-old A. senegal plantation. The results indicated that A. senegal trees had a beneficial effect on crop performance and yield at both experimental sites. Crop growth and yield were increased in the alley-cropping system. The highest yield increase was observed with sesame (56%) in South Kordofan. It is hypothesized that the beneficial effect was mainly due to the more favourable soil nutrient and water status under canopies, compared to that in the open field. The findings of the present investigation indicated that alley cropping, as a form of agro-forestry, is a feasible farming practice in North and South Kordofan.
