The complimentary effects of a native rhizobia strain (SAMFIX 286), lime and single superphosphate (SSP) as components of ISFM were evaluated on the biomass, nodulation and N2 fixation of cowpea (Vigna unguiculata L.). Lime was applied at the rate of 250 kg (Ca(OH)2) ha−1, while SSP was applied a...

Availability of knowledgeable personnel and improved laboratory capacity for assessing commercial agricultural products
The use of microbial inoculants and less expensive sources of plant nutrients such as foliar fertilizers are ways to practice low-input agriculture, especially in sub-Saharan Africa where smallholder farmers’ soil nutrients are depleted. However, the application of microbial inoculants and foliar...

Effects of commercial microbial inoculants and foliar fertilizers on soybean nodulation and yield in northern Guinea savannah of Nigeria
The adaptability of cassava to low fertile and marginal soils facilitates its production in subsistent agriculture. As a result, smallholder farmers rarely apply fertilizers. The current yield gap is therefore very large, calling for application of fertilizers and soil amendments to improve its p...

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...

Three inoculation trials with soybean, cowpea and groundnut were conducted on Eutric Cambisols (EC) and Rhodic Nitisols (RN) in a greenhouse. Five rhizobial inoculants: MAR 1495, TSBF Mixture, Legumefix, HiStick and IRJ 2180A were tested on each crop to determine their response to soil type and a...
