Potential N (SN) and P (SP) supplies, N and P utilization efficiencies and fertilizer recovery rates for the northern Guinea Savanna (NGS) agro-ecological zone of Nigeria were derived from data collected on farmers fields, and used as input in the QUantitative Evaluation of the Fertility of Trop...

Assessment of nutrient deficiencies in maize in nutrient omission trials and long-term field experiments in the West African Savanna
Two crop rotation cycles were evaluated to determine the effect of cropping systems and N
fertilization on the yield and efficiency of N in maize. Maize was grown on plots which had previously
supported monocrops of two genotypes each of soybean (TGx 1448-2E and SAMSOY-2) and cowpea
(IT 96D-724 a...

Grain legume rotation benefits to maize in the northern Guinea savanna of Nigeria : Fixed-nitrogen versus other rotation effects
Nutrient depletion is a major constraint to crop production for moist savanna soils, and inputs of nutrients are required to overcome this constraint. The impact of sole and combined applications of organic inputs (OIs) [fresh tree prunings, Pueraria phaseoloides (Roxb.) Benth. residues, and manu...
