dc.description.abstract | A pot experiment was conducted in the screen house of Kwara State University, Malete, Nigeria to compare the effect of sources of nitrogen fertilizers on soil chemical properties on two maize varieties (SUSWAM and LNTP-Y), growth and dry matter yield as well as its residual effect. The treatments comprised of control, poultry manure, granular urea, prilled urea and neem coated urea at 100 and 110 kg N/ha respectively, each replicated three times and fitted into a completely randomized design (CRD). Growth and yield parameters taken were; plant height, number of leaves, stem girth and dry matter yield. Moreover, the results showed that application of neem coated urea and poultry manure at 100 and 110 kg N/ha respectively significantly (p< 0.05) increased the growth and yield parameters of the both maize varieties when compared with other fertilizer treatments at first and second planting. Application of poultry manure at 110 kg N/ha had a significant and additive effect on soil nutrients after harvesting of SUSWAM and LNTP-Y maize varieties at first and residual planting followed by neem coated urea at 100 kg N/ha. Therefore, neem coated urea at 100 kg N/ha and poultry manure at 110 kg N/ha could serve as a fertilizer for the production of maize variety and soil amendment. | |
