Abstract
A greenhouse experiment was carried out to study the effects of cattle manure and poultry litter on the avialability of major and minor nutrients to cowpea [Vigna unguiculata (L.) Walp.]. Rates of manure and litter were 20, 40,60,80 and 100 metric tones ha-1. Tissue analysis were made for different nutrients. The aviallability and content of macro- and micro-nutients and heavy metals were increased by application of manure, as was determined by plant tissue analysis studies. As a result dry matter yield and yield components were also significantly affected by manure application. In general, nutrient avialability in cowpea was much affected by application of cattle manure and poultry.
