Effect of Balanced Fertilizers and Lime Rate on Maize (Zea mays L) Yield in Omo Nada District, Southwestern Oromia, Ethiopia

Declining of soil nutrients is among the factors that lead to low crop yields in Sub-Saharan Africa including Ethiopia. The experiment was conducted to verify and demonstrate the beneficial effect of lime and balanced fertilizer application rate in improving the yield of Maize on acid soils of Omo Nada district. The experiment comprised seven treatments namely; Control, NPS, NPSB, NPSB with 100% recommended rate of Lime, NPSB with 75% recommended rate of Lime, NPSB with 50% recommended rate of Lime and NPSB with 25% recommended rate of lime were laid out in Randomized Complete Block Design (RCBD) replicated across ten farmers’ fields. Data analysis was conducted on grain yield data to detect variation among treatments. Partial budget analysis was also done to determine the economic feasibility of treatments. The results revealed that there were highly significant differences (P < 0.01) among treatments in their effect on grain yield of maize. Accordingly, NPSB with full recommended lime gave significantly superior yield of maize (in sites. This treatment increased the mean grain yield over the control by 27.26 qt/ha yields advantages. Application of lime alone did not increase the yield of Maize in all sites suggesting that the soil were severely depleted of essential nutrients. The result of partial budget analysis data also showed that the highest net benefit and marginal rate of return (466%) was obtained from NPSB with full recommended lime. Finally, the highest biological and economical yield of Maize was obtained from NPSB treatment applied at 100 kg/ha and full recommended rates of lime. Results suggest that nutrient depletion can be mitigated in the area through using of lime; hence longer-term productivity of smallholders can be sustained.
