dc.description.abstract | Water production functions (wpf) giving the relation between crop yield and water application under furrow irrigation on a clay loam soil in the semi-arid region in Kenya (Perkerra) were derived for maize and onion. Due to deep percolation the functions were found to be curvilinear. The seasonal yield response factors Ky, giving the relationship between evapotranspiration deficit and yield depression for maize and onion for the area was computed as 1.21 and 1.28, respectively. Analytical analysis using the derived wpf for maize and existing conditions in an irrigation system located in the area confirmed that if rainfall is significant, deficit irrigation will be more attractive, and at a certain point, it is profitable to cultivate all available area. | en_US |
