Abstract:

The field study was conducted for two consecutive years in the Dore Bafeno and Meskan districts of the central rift valley of Ethiopia, to determine optimum rates of NPS and Urea fertilizers for better maize yield and economic profitability. The experiments were comprised the fourteen treatments: (150 kg ha^-1NPS + 150 kg ha^-1Urea), (200 kg ha^-1NPS + 150 kg ha^-1Urea), (250 kg ha^-1NPS + 150 kg ha^-1Urea), (300 kg ha^-1NPS + 150 kg ha^-1Urea), (150 kg ha^-1NPS + 250 kg ha^-1Urea), (200 kg ha^-1NPS + 250 kg ha^-1Urea), (250 kg ha^-1NPS + 250 kg ha^-1Urea), (300 kg ha^-1NPS + 250 kg ha^-1Urea), (150 kg ha^-1NPS + 350 kg ha^-1Urea), (200 kg ha^-1NPS + 350 kg ha^-1Urea), (250 kg ha^-1NPS + 350 kg ha^-1Urea), (300 kg ha^-1NPS + 350 kg ha^-1Urea), control and Recommended NP (92N 69 P₂O₅) and laid out in a randomized complete block design with three replication. At the Dore Bafeno site, the pooled mean analysis results showed that the application of 250 kg ha^-1NPS fertilize plus 250 kg ha^-1. Urea gave the maximum above-ground biomass (17259.0kg ha^-1) and grain yield (6738.7kg ha^-1). While at the Meskan site, the combined use of 200 kg ha^-1NPS fertilize with 250 kg ha^-1Urea produced the greater grain yield (6964.1 kg ha^-1) and above ground biomass (17053.2 kg ha^-1). In sites, however, the unfertilized plots gave the minimum grain and above ground biomass yields. Like agronomic performance, the application of 250 kg ha^-1NPS fertilize plus 250 kg ha^-1Urea and 200 kg ha^-1NPS fertilize with 250 kg ha^-1Urea revealed the maximum net benefit value of 84147.4 ETBha^-1 and 88376.7 ETB ha^-1 for Dore bafeno and Meskan sites, respectively. Therefore, the combined application of 200 kg ha^-1 NPS with 250 kg ha^-1 Urea fertilizers and 250 kg ha^-1 NPS with 250 kg ha^-1 Urea fertilizers were the best treatments for Dore bafano and Meskan sites, respectively.
