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...

En el invernadero se evaluó la efectividad de las cepas preseleccionadas de B. japonicum (CIAT 199,209,3778,3874 y 3876) de la recomendada (CIAT51) y una de Rhizobium spp (CIAT 3779). En el suelo Fluventic Haplustoll, de reacción casi neutra, se presentó respuesta altamente significativa a la ino...

The development of innovative rice products is a way to exploiting and adding value to low-grade African rice varieties. To this purpose, rice-based pasta was enriched with flours from soybean and orange-fleshed sweet potato, that are common ingredients in the African tradition. Four different fo...

The dynamics of deforestation in the Brazilian Amazon are complex. A growing debate considers the extent to which deforestation is a result of the expansion of the Brazilian soy industry. Most recent analyses suggest that deforestation is driven by the expansion of cattle ranching, rather than so...

High population growth and consequent pressure for food is driving agriculture towards greater intensification in West Africa. However, due to inadequate use/availability of farm manure and fertilisers, there is a continuous decline in soil fertility and overall crop productivity. This trend must...

Background and aims Incorporating soybean (Glycine max) genotypes with a high nitrogen fixation potential into cropping systems can sustainably improve the livelihoods of smallholder farmers in Western Kenya. Nitrogen fixation is, however, often constrained by low phosphorus (P) availability. The...

In order to determine the improved soybean varieties that if recommended to the farmers would have a high probability of adoption, a farmer participatory approach was used to evaluate 12 soybean varieties at full podding in five locations (Oyani, Riana, Kasewe, Akiites, and Mabole) in western Ken...

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...

Crop promotion is critical for market creation and rural growth in Africa. How to achieve this for crops, other than major staples (e.g., maize) and traditional export crops (e.g., tea), remains a problem since most African countries tend to focus policy attention to major staples and traditional...
