Nitrogen (N) has been gradually depleted from West African soils and now poses serious threats to food production. Many ways of increasing N supply (e.g. judicious use of inorganic fertilizers and nitrogen-fixing plants) have been tried in West African farming systems. Herbaceous and woody legume...

Striga hermonthica a major biotic constraint to cereal production can be controlled by trap crops. Soybean cultivars vary in ability to stimulate suicidal germination of the weed. An experiment was conducted to select soybean (Glycine max) varieties with the ability to stimulate germination of S....

Determination of water requirement for crops in resource limited areas is challenging, yet worsened by the common assumption that all crop varieties within a species have similar water requirements. The objective of the study was to indirectly determine crop evapotranspiration of soybean variet...

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...

Recurrent selection programs can be manipulated by varying either the extensiveness of testing used to identify superior lines or the number of intermating generations conducted among the superior lines between cycles of selection. The research was conducted to compare the performance of soybean ...

Six experiments with sorghum, soybean, and the weed purple nutsedge were conducted in the screenhouse of the Centro Internacional de Agricultura Tropical (CIAT), Palmira, Colombia. The objective was to determine if purple nutsedge produced inhibitors which affect crop growth and to study the effe...

Two new ‘legumoviruses’ (genus Begomovirus; family Geminiviridae) naturally infecting soybean (Glycine max L. Merr.) in Nigeria were molecularly characterized. Based on characteristic symptoms in soybean, the two viruses are provisionally designated as Soybean mild mottle virus (SbMMV) and Soybea...
