Abstract

Nutrient deficiencies are the most important problems influencing maize production in the mid and low altitude sub-humid agro-ecologies of Ethiopia due to limited use of commercial inputs and lack of soil fertility enriching rotations or fallows. Due this on-farm study of blended NPS fertilizer for maize was executed in Dugda District, East Shewa Zone of Oromia, during the main cropping seasons of 2018-2019. The main objective of the study was to assess the effect of of blended NPS fertilizer levels on yield and yield components of Maize variety (MHQ 138) and to determine economically appropriate level of blended NPS fertilizer for optimum maize crop production in Dugda District. The treatments were arranged based on already determined Phosphorous critical (Pc) and phosphorus requirement factor (Pf) and consisting of 100% Pc from TSP (Triple supper phosphate) fertilizer, 100%, 75%, 50%, 25% Pc from blended NPS fertilizer and control (no fertilizer application). Applied Phosphorus = (Critical P - Po)* Pf. Whereas Pc= 10 ppm and Pf = 4.68 ppm. The experiment was laid out in randomized complete block design (RCBD) with three replications. Inter and intra row spacing was 0.75 x 0.25m respectively. The results of the study showed that, different levels of phosphorus critical from blended NPS and TSP fertilizers did not significantly (p <0.05) influenced ear height, number of rows per ear and thousand kernels weight of maize crop in study area. However, plant height, biomass yield, grain yield, harvest index and cob weight were highly significantly (p <0.01) influenced by different levels of phosphorus critical from blended NPS and TSP fertilizers. The highest (2008cm) plant height, the highest (6123kg ha-1) grain yield, and the highest (52.67kg ha-1) cob weight were recorded by application of the highest 100% Pc (168kg ha-1) while the highest (20.14 tone ha-1) biomass yield and the highest (32.77%) harvest index were recorded by 100 pc TSP and 75% PC NPS respectively. The economic analysis showed that for a treatment to be considered as worthwhile to farmers (100% marginal rate of return) application of 100 Pc NPS (168 kg NPS ha-1) is profitable which gave the highest (35073 Birr) net return with acceptable (102%) marginal rate of return and recommended for farmers in Dugda district and other areas with similar Agro-ecological conditions.
