Striga hermonthica (witch weed) infestation and low soil fertility are two major constraints to maize production in western Kenya. The low inherent soil fertility and poor crop management practices result in subsequent ...

Soybean is a good source of protein and calories and therefore important for food security. Soybean yields in western Kenya stand at 0.6 t ha-1 season-1against a potential of 3 to 3.6 t ha-1 season-1. This has been attributed ...

Poor soil responsiveness to fertilizer application is an emerging problem whose cause is yet to be well understood. This was the basis for a study in Western Kenya to unravel the underlying physical characteristics of these ...

Climate change is a fundamental threat to food security, development and the fight against poverty. Identification of strategies to alleviate its impacts on agriculture is essential. One such strategy is making future ...

Maize (Zea mays) and soybean [Glycine max (L.) Merr] grain yields in smallholder farms of western Kenya are persistently low, particularly in soils that respond poorly to fertilizer application. A multi-locational trial ...

Phosphorus deficiency remains a key constraint to cowpea productivity in Kenya. In addition, there exist conflicting results about the effect of leaf harvest on cowpea yield. Therefore, an on-farm and greenhouse study was ...

The use of promiscuous soybean varieties and commercial inoculants has been shown to increase production and improve soil fertility. However, most cropping systems are characterized by indigenous bradyrhizobia whose ...
