Abstract
Current a field trial was conducted at the University Commercial Crops Farm, University of Agriculture, Makurdi, Nigeria in 2014 and 2015 cropping seasons to evaluate yield response of sorghum to two manure sources. The study consisted of four levels of poultry manure (0, 2.0, 3.5 and 5.0) t/ha, and organic NPK® (0, 0.2, 0.4 and 0.6) t/ha and control. The treatments were laid out in a 4 × 4 factorial in Randomized Complete Block Design (RCBD) and replicated three times. The soil samples were collected processed and analyzed for soil nutrients before and after planting. The result of crop data collected indicated a significant increase in crop yield with manure application over control. The highest grain yield was obtained from organic NPK® at 0.6 t/ha. Soil pH, OM, N, P and CEC of the soil were improved by manure application indicating a positive effect of its continuous use as a soil amendment.
