The trial objectives were to determine the agronomic and economic benefits of growing maize at three cropping densities (29,260, 44,444, and 59,260 plants/ha) and three NP rates (control, 40N+40P205 and 80N+80P205 kg/ha) using a compound fertilizer NPK 20:20:0. The test crops were local maize (Ababari) and hybrid maize (H512). A split-split plot in a randomized complete block design with three replications at each site was used. The results showed that there was no significant difference in the grain yield of the two maize varieties in 1994. In 1995, Ababari significantly outyielded H512. Effect of density on the grain yield was not significant across all sites. Fertilizer application at the rate of 40kg NP/ha significantly (p=0.05) increased maize grain yield and was more profitable than the higher rate of 80kg NP/ha. There were no significant interactions between the main factors.Collection: CIMMYT Publications Collection
