Effect of Poultry Manure Application Rate on the Growth and Yield of Cowpea under two Growing Season

- Poultry manure contains appreciable amounts of nutrients required by plants. It decomposed in the soil, releasing for plant uptake. A field experiments were conducted at the School of Agriculture and Food Sciences experimental research site to determine poultry manure rate and season that gives optimal yield in cowpea. The experimental was carried out using Randomized Complete Block Design (RCBD) in a split plot arrangement, replicated three times. The rates of well decomposed poultry manure levels (0 t ha-1, 5 t ha-1, 10 t ha-1, and 15 t ha-1) was the main plot treatment in both dry season and raining season. Plot size was 4m X 3m (8m2), with a total experimental area was 125.5m2 (20.5 m x 11 m) with a planting spacing of 50 cm x 20cm in both season. However, cowpea growth and yield was significantly by poultry manure rate and season planted. Application of 15t/ha. Produced significantly (≤0.05) taller plants, more leaves, thicker stem, and broader leaves and pod yield/ha, grain yield/ha and biomass than either 0 or 5t/ha. Cowpea grown during the dry season with constant irrigation produced better cowpea growth and yield than planting in the raining season. Therefore, for optimal growth and yield of cowpea, it is appropriate to apply 15t/ha especially during the second planting season.
