Growth and Yield Performance of Cowpea (Vigna unguiculata L) Under Different Organic Mulch Materials
A study was conducted on growth and yield of cowpea (Vigna unguiculalta L) under different mulch materials on an Alfisol in the Teaching and Research farm of Ambrose Alli University, in Ekpoma, Nigeria. Mulch materials increased the soil pH, organic carbon, total nitrogen, available phosphorus and carbon exchange capacity of the soil over control. At 3 and 6 weeks after planting, cocoa husk and empty fruit bunch recorded significant higher plant height, leaf area and number of leavers of cowpea plant over cassava peels and control.
