Growing soybean varieties with high residue yield may help to sustain the soil organic matter (SOM) content when recycled. Replicated field trials were conducted in four Guinea savanna sites in Nigeria to study the dry matter partitioning in six soybean genotypes and evaluate them for biomass pro...

The symbiotic performance of promiscuous soybeans depends upon the population size, effectiveness and survival of indigenous or introduced rhizobia in the field. A pot experiment was conducted using soils collected from 13 farmers' fields located in two agroecological zones (northen and southern ...

Phosphorus fertilizer was applied at two rates to four soyabean varieties of different duration to maturity at four sites. The P rate had no significant (p > 0.05) interaction with site or variety. TGx1670-1F, one of the two late varieties, had the highest levels of total P (11 kg/ha) and apparen...
