Effect of Compound (NPSB) Fertilizer Type on Yield and Nutrient use Efficiency of Maize (Zea mays L.) at Beko Village in Yeki District, Southwest Ethiopia

Farmer in different parts of Ethiopia uses a similar type fertilizer and amounts that are below the crop requirements, even low soil fertility which limits production general. To solve over-blanket application over agroecology Ethiopian Soil Information System (EthioSIS) mapped recommended types for specific location. A NPSB where Beko village, but rate this was not studied so far. So, field experiment conducted to determine nutrient use efficiency maize during 2018 cropping season. total eight treatments with four replications were laid out factorial randomized complete block design. Treatments control (zero fertilizer), previously blanket nitrogen phosphorus (92 N+ 69 P2O5) kg/ha, 150 +100 urea K2O 200 + 100 250 +150 kg/ha kg/ha. Data statistically analyzed by statistical analysis system (SAS) mean treatment differences compared least significant (LSD). An variance indicated influenced plant height, ear length, cob number ears per plant, thousand seed weight, harvest index, shelling percentage as Nitrogen Phosphorus (NP) grain above-ground dry biomass except urea. Application gave highest yield (8828.2 kg/ha). improved NP. The N (64.75 kg/ha) obtained from urea, while lowest (23.89 NP fertilizer. As economic is study area.
