| 1 | Comparative Evaluation of Organo-Mineral Fertilizer (OMF) and Mineral Fertilizer (NPK) on Yield and Quality of Maize (Zea mays (L) Moench) |
The continuous use of sole mineral fertilizer in tropical soil has been associated with reduced crop yield, increased soil acidity and nutrient imbalance. The combination of both organic and mineral fertilizers (Organi-mineral fertilizer -OMF) has been found to be a better fertilizer management for these soils. An experiment was therefore carried out to compare the effect of mineral fertilizer NPK 15:15:15 and a local OMF on yield and quality of maize (Zea mays). OMF at these rates of 3.0 and 1.5 t/ha, NPK 15:15:15 at 300 kg/ha and the control (no fertilizer application) were used to plant maize (SUWAN -1-DMR-SR-W) on the field in a randomized complete block design replicated three times. Data collected on plant growth and yield parameters were subjected to statistical analysis using Duncan Multiple Range Test and a simple economic analysis. Performance of maize as a result of the treatments in the order of 3.0 t/ha OMF>1.5 t/ha of OMF>300 kg/ha NPK 15:15:15 >control with grain yields of 6.52, 6.06, 5.40 and 2.02 t/ha respectively. since there was no significant difference (p<0.05) between the grain yields resulting from 3.0 t/ha and 1.5 t/ha of OMF, the use of 1.5 t/ha Pacesetter's OMF grade A was therefore judged more economic than at 3.0 t/ha for tropical soils with similar nutrient status and agro-ecology. | Adeoye, G.O., AdeOluwa, O.O., Oyekunle, M., Sridhar, M.K.C., Makinde, E.
