Sustainable resource management coupled to resilient germplasm to provide new intensive cereal-grain-legume-livestock systems in the dry savanna.
TLDR
Two sustainable farming systems that greatly enhance the productivity and sustainability of integrated livestock systems have been developed and implemented in the dry savanna of Nigeria and economic analysis of these systems shows already an increase of 50–70% in the gross incomes of adopting farmers compared to those still following the current practices, mainly continuous maize cultivation.
Population size, distribution, and symbiotic characteristics of indigenous Bradyrhizobium spp. that nodulate TGx soybean genotypes in Africa
TLDR
The group IV isolates represent a unique subgroup of indigenous bradyrhizobium that can sustain high soybean yields when available in sufficient population densities and has the potential to compromise the selection pressure anticipated from the indigenous Bradyrhzobium spp.
Improvement in Grain and Fodder Yields of Early‐Maturing Promiscuous Soybean Varieties in the Guinea Savanna of Nigeria
TLDR
Grain yield showed a positive and highly correlation coeffi cient (r = 0.75) correlation with fodder yield, implying that high biomass could serve as an indicator of good yielding ability.
Nitrogen fixation and N contribution by promiscuous nodulating soybeans in the southern Guinea savanna of Nigeria
TLDR
Assessment of symbiotic N2 fixation and response to inoculation and N contribution of three IITA promiscuous and two Brazilian soybean lines grown in the field at Mokwa (southern Guinea savanna) for two years found that soybean growth led to a net contribution of an average of 18 kg N ha-1 to soil N.
The contribution of nitrogen by promiscuous soybeans to maize based cropping the moist savanna of Nigeria
TLDR
The differential mineralization and immobilization turnover of maize and soybean residues in these soils may be important and N contribution estimates in longer term rotation involving legumes and cereals may be difficult to quantify using the 15N labelling approaches.
Persistence and effectiveness of rhizobia nodulating promiscuous soybeans in moist savanna zones of Nigeria
TLDR
A relationship between rhizobia cell counts and promiscuous soybean responses is indicated, which may be used to indicate under which conditions inoculation will be beneficial to a farmer.
Effectiveness of rhizobia nodulating recent promiscuous soyabean selections in the moist savanna of Nigeria
TLDR
The ability of soybean to nodulate with a wide range of indigenous bradyrhizobia strains has been used in a breeding programme since 1997 in Nigeria, but the degree of effectiveness depended on the plant genotype and field sites.
Characterization of resistance to Aphis glycines in soybean accessions
TLDR
Growth-chamber experiments were conducted to determine and characterize host-plant resistance among several soybean accessions, confirming Dowling and PI 71506 as strong sources of resistance to A. glycines and suggesting these accessions may also be valuable to soybean breeding programs as sources of Resistance.
A Land Management Based Approach to Integrated Striga hermonthica Control in sub-Saharan Africa
TLDR
An integrated programme that replaces traditional bush fallow rotation with non-host nitrogen-fixing legume rotations, using cultivars selected for efficacy in germinating S. hermonthica seeds, is outlined.
