Abstract: |
Declining maize yields in the Guinea Savanna ecological zone of Ghana call for effective nutrient management strategies that increase maize productivity and profitability among small- holder farmers. Field trials were conducted during 2016 and 2017 in three locations in northern Ghana to evaluate the agro- nomic effectiveness of one-time application of multi-nutrient fertilizer briquettes for maize production. The treatments were: (i) farmer practice (FP); (ii) NPK fertilizer briquettes applied at the recommended N, P, and K rates (100%-Briquette); (iii) 75%-Briquette; (iv) modified farmer practice (MFP) with N, P, and K applied at the recommended rate (100%-MFP); (v) 75%- MFP; and (vi) control, with no fertilizer applied. The farmer practice involved surface broadcasting the granular N, P, and K fertilizer at the recommended rate. The MFP involved subsur- face incorporation of the granular fertilizer into the soil. Across all three locations and in both years, maize grain yield result- ing from the treatments followed this order: 100%-Briquette > 100%-MFP = 75%-Briquette > 75%-MFP > FP > control. Despite the greatest grain yields resulting from the 100%-Bri- quette treatment, the greatest gross profit margin of 0.46 was obtained with the 75%-Briquette treatment, followed by the 100%-Briquette treatment (~0.43), 100%-MFP (~0.39), 75%- MFP (~0.24), and FP (0.03). From the combined results, we conclude that the one-time application of multi-nutrient fertil- izer briquettes could be an efficient fertilizer management strat- egy to increase maize yields and profitability for smallholder farmers in the Guinea Savanna zone. This presents a real strat- egy for improved productivity across diverse agroecologies for food security among smallholder farmers. |
