Economic Returns of Integrated use of Poultry Manure and Inorganic Fertilizers on Maize Yield in Akure, Nigeria
- Dada B. F.; Ewulo B. S.
- An experiment was conducted to determine the economic returns of the use of poultry manure and inorganic fertilizer for maize (TZB-SR) cultivation at the Teaching and Research Farm of the Federal University of Technology, Akure. The treatments consisted of two level of poultry manure 0 and 5 t ha-1, three levels of urea 0, 50 and 100 kg ha-1 and three levels of phosphorus 0, 30, and 60 kg ha-1 at both early and late season maize cultivation. The resultant eighteen treatment combination ratio was used as the basis for evaluating economic returns. Poultry manure was applied by broadcasting two weeks before planting. Single Supper Phosphate was placed in planting hole and covered with a thin layer of soil before planting the maize seed. Urea fertilizer was applied in ring form to the base of the plant immediately after thinning. Three maize seed were planted per hole at 75 x 25 cm spacing and later thinned to one at two weeks after planting. The total grain yield (t ha-1) was determined at harvest. Total variable costs (TVC), Total revenue (TR) for all sales from the crop were determined. Gross margin (GM) analysis was carried out and Cost of Response of fertilizer input (CRFI) determined. The result showed total variable cost as highest for 0 PM + 100 U + 60 SSP and 5 PM + 100 U + 60 SSP combining ratio in both the early and late season cultivation, 5 PM + 100 U + 30 SSP combining ratio has the highest yield of 4.12 t ha-1 for early season maize cultivation and highest yield of 2.99 t ha-1 for late season maize cultivation, it also has the highest Total Revenue (TR) of N288,400 and N209,300 at the early and late season maize cultivation respectively, the highest Gross Margin (GM) and Cost of Response of fertilizer input (CRFI). 5PM + 100 U + 30 SSP combining ratio was recommended for maize cultivation.
