Masso, C.Mitiku, G.Shimber, T.Abaidoo, R.C.Mungai, N.Yusuf, A.A.Mhaiki, K.Tumuhairwe, J.B.[Availability of knowledgeable personnel and improved laboratory capacity for assessing commercial agricultural products]Availability of knowledgeable personnel and improved laboratory capacity for assessing commercial agricultural products

The growing population and the increasing food demand in sub-Saharan Africa require comprehensive land use intensification. Land scarcity and soil degradation are some consequences that necessitate enhanced land use management by using remote sensing data. This study presents the analyses of aeri...

Soybean is a relatively new crop to most African smallholder farming communities. Cultivation is expanding rapidly because of its perceived potential to enhance soil fertility through biological nitrogen fixation and its source as food and cash. High N2, fixation in promiscuous soybean genotypes ...

Abaidoo, R.C.Sanginga, NteranyaOkogun, J.A.Kolawole, G.O.Tossah, B.K.Diels, J.[Genotypic variation of soybean for phosphorus use efficiency and their contribution of N and P to subsequent maize crops in three ecological zones of West Africa]Genotypic variation of soybean for phosphorus use efficiency and their contribution of N and P to subsequent maize crops in three ecological zones of West Africa

Plants growing in acid soils suffer both phosphorus (P) deficiency and aluminum (Al) toxicity stresses. Selection of genotypes for adaptation to either P deficiency or Al toxicity has sometimes been unsuccessful because these two soil factors often interact. Two experiments were conducted to eval...

A field study of cowpea, soybean and maize was made at Ibadan, Nigeria, to determine the uptake of mineral nutrients and quantities removed in crop residues and seed. Concentrations of N, the major cations (K, Ca, Mg and Na) and major anions (P, S and Cl), and the micronutrients (Fe, Mn, Zn and C...

The cultivation of soybean is increasing in the savannas of Nigeria due to its widespread use in the food and feed industry. Production is, however, constrained by low soil phosphorus (P) levels in northeast Nigeria. This study evaluated four soybean varieties for their response to three rates of...


Kamara, A.Y.Abaidoo, R.C.Kwari, J.Omoigui, L.O.[Influence of phosphorus application on growth and yield of soybean genotypes in the tropical savannas of northeast Nigeria]Influence of phosphorus application on growth and yield of soybean genotypes in the tropical savannas of northeast Nigeria

Root colonization by arbuscular mycorrhiza (AM) enhances nutrient acquisition by plants and could benefit the production of yam (Dioscorea spp.). The variation in AM colonization in yam genotypes was evaluated in two experiments at four locations (Ibadan, Onne, Abuja and Ubiaja) in different agro...

Field data have suggested that under P-deficient conditions, legumes supplied with phosphate rock (PR) increase P acquisition by a subsequent maize crop compared to direct application of PR to maize. This study assessed the mechanism of this positive rotational effect in terms of soil P availabil...

To identify interventions which reduce health risks of consumers where highly polluted irrigation water is used to irrigate vegetables in West Africa, scientists worked over 5 years with farmers, market traders and street food vendors in Ghana. The most promising low-cost interventions with high ...
