Experiment was conducted in a Screen House in the Department of Biological Sciences, Ahmadu Bello University Zaria. The objective was to compare the effect of poultry manure (Layer and Broiler) on the growth and potential yield of cowpea plant using one level of the manures (55g/g).The experiment was laid out in a randomize complete design and replicated three times. The result shows that Cowpea plants grown in soil mixed with Layer manure produced significantly (p<0.05) higher number of leaves, stem diameter, taller plants compared with the plants grown with soil mixed with Broiler manure and those grown in only loamy soil. Similar results were also observed for Stem dry weight, Leaf dry weight, number of pods and pod dry weight. These results suggest that differences in nutrient composition of manure could result to differences in growth and yield parameters. And that Layer manure could produce better growth and probably more yield on Cowpea than Broiler manure.
In conclusion, this study have showed differences in nutrient composition between Layer manure and Broiler manure, and these differences have translated into differences in growth and yield of Cowpea. The study suggests that optimum performance in terms of growth and yield for the variety of Cowpea used in this study may be best achieved using Layer manure than Broiler manure.
