摘要

Appropriate fertilization practices based on actual limiting nutrients and crop requirement for a given crop is economic and judicious use of fertilizers for sustainable crop production. In view of this, a study was conducted at Kejo and Ongobo farmers' fields, located at GobuSeyo District of East Wollega Zone of Oromia region in 2011 to evaluate the effects of blended fertilizers for maize production. The five treatments used for the field experiment were control (without fertilizer), recommended NP, recommended NP + Cu + Zn, blended fertilizer and blended fertilizer + Cu+ Zn. The treatments were laid out in RCBD design with four replications. The results of the study revealed that the analysis of variance among fertilizers types showed significant differences (P ≤ 0.05) on almost all the maize characters tested. However, applied Cu and Zn to either of the recommended NP fertilizers or blended fertilizer showed no significant difference on maize agronomic characters and yield except leaf area. The shortest mean days to 50% tasseling (85.25), silking (87.25) and maturity (154.25) of maize were obtained from blended fertilizers with Cu and Zn, whereas the longest days were recorded for the control plot. The maximum mean grain yield (8399.7 kg ha~(-1)), stover yield (8553.1 kg ha~(-1)) and total biomass yield (16867.7 kg ha~(-1)) were recorded for blended fertilizers with Cu and Zn, whereas the lowest mean grain yield (2824.8 kg ha~(-1)) were recorded for control. Blended fertilizers had improved grain nutrient uptakes and agronomic efficiency of maize. It was also apparent that much of the nutrients applied were assimilated by the grain than that achieved by the stover. The result of the study showed that blended fertilizers increased maize productivity compared to the previously existing NP fertilizers in the country and appropriate fertilization practices can improve the current situation.
