Abstract
Black plastic, cassava peel, and giant star grass and guinea grass straw soil mulches were compared for field-grown vegetables under varying rates of nitrogen (N) fertilization. Black plastic mulch was most effective in weed control and resulted in more crop growth and higher fruit yield. Low weed control and a high incidence of fungal disease with cassava peel depressed yields, thus rendering cassave peel unsuitable for mulching. There was no advantage in applying fertilizer N beyond 80 kg N ha−1, irrespective of mulching or the type of mulch.
