Promiscuous soyabean varieties have potential to contribute significantly to income generation, food security and soil N budgets on smallholder farms. One of the major factors limiting this potential is farmers preference to allocate nutrient resources to food security cereal crops on the most f...


Zingore, ShamieMurwira, HKDelve, Robert J.Giller, Ken E.[Variable grain legume yields, responses to phosphorus and rotational effects on maize across soil fertility gradients on African smallholder farms]Variable grain legume yields, responses to phosphorus and rotational effects on maize across soil fertility gradients on African smallholder farms

Canavalia ensiformis, Crotalaria grahamiana, Dolichos lablab, Mucuna pruriens, Tephrosia vogellii and Tithonia diversifolia were evaluated as potential species for soil fertility replenishment in on-farm adaptive trials, farm visits and field days in Tororo District, eastern Uganda. Farmers used ...


Nyende, PDelve, Robert J.[Farmer participatory evaluation of legume cover crop and biomass transfer technologies for soil fertility improvement using farmer criteria, preference ranking and logit regression analysis]Farmer participatory evaluation of legume cover crop and biomass transfer technologies for soil fertility improvement using farmer criteria, preference ranking and logit regression analysis

Amidst the economic backdrop of resource-poor farmers, combined research and extension efforts in developing countries have focused on developing and promoting potentially adaptable and economically acceptable agronomic technologies that suit farmers situations. Practices like improved fallows w...


Delve, Robert J.Huising, JeroenBagenze, P[Target area identification using a GIS approach for the introduction of legume cover crops for soil productivity improvement : A case study eastern Uganda]Target area identification using a GIS approach for the introduction of legume cover crops for soil productivity improvement : A case study eastern Uganda

Knowledge of soil spatial variability is important in natural resource management, interpolation and soil sampling design, but requires a considerable amount of geo-referenced data. In this study, mid-infrared spectroscopy in combination with spatial analyses tools is being proposed to facilitate...

Delve, Robert J.Probert, ME[Modelling nutrient management in tropical cropping systems]Modelling nutrient management in tropical cropping systems

The increasing attention paid to local soil knowledge results from a greater recognition that farmer knowledge can offer many insights into the sustainable management of tropical soils and that the integration of local and technical knowledge systems helps extension workers and scientists work mo...
