Does nitrogen matter for legumes? Starter nitrogen effects on biological and economic benefits of cowpea (Vigna unguiculata L.) in Guinea and Sudan Savanna of west Africa por Nurudeen, A.R., Larbi, Asamoah, Kotu, Bekele Hundie, Tetteh, F.M., Hoeschle-Zeledon, I.

“…The hypothesis that application of starter nitrogen (N) fertilizer to cowpea may increase grain and fodder yields and profitability was tested in the Guinea and Sudan savanna zones of northern Ghana. Two cowpea varieties (Apagbaala: grain-type and Padi-Tuya: dual purpose) and three N fertilizer rates (0-30-30, 15-30-30 and 30-30-30 N-P2O5-K2O kg/ha) were evaluated using a 2 × 3 factorial treatments arrangement in a randomized complete block design with three replicates. …”

Diagnosis of crop secondary and micro-nutrient deficiencies in sub-Saharan Africa por Wortmann, Charles S., Kaizzi, K.C., Maman, N., Cyamweshi, A., Dicko, M., Garba, M., Milner, M., Senkoro, C., Tarfa, B., Tettah, F., Kibunja, C., Muntholi, M., Nalivata, P., Nkonde, D., Nabahungu, L., Ouattara, K., Serme, I.

“…The r2 values for relationships between soil test, foliar test and RYR results were < 0.035 with little complementarity except for soil test Zn and B with cassava (Manihot esculenta L. Crantz) RYR in Ghana, and foliar Zn with cereal RYR in Uganda. Positive RYR is powerful diagnostic information and indicative of good profit potential for well-targeted and well-specified SMN application. …”
