P. R.Item Crop water productivity of an irrigated maize crop in Mkoji sub-catchment of the Great Ruaha River Basin, Tanzania(Elsevier, 2006-09-16) Igbadun, Henry E; Mahoo, Henry F; Salim, Baanda A; Tarimo, Andrew K. P. R.Crop water productivity (CWP) is a quantitative term used to define the relationship between crop produced and the amount of water involved in crop production. It is a useful indicator for quantifying the impact of irrigation scheduling decisions with regard to water management. This paper presents CWP quantified from field experimental data. Three fields were cultivated to maize under irrigation during the 2004 dry season in a traditional irrigation scheme in Tanzania. The maize crop was irrigated at eight different seasonal water application depths: 400, 490, 500, 510, 590, 600, 610 and 700 mm, in two of the three fields, and at five water application depths: 400, 590, 600, 610 and 700 mm in the third field. The variation in seasonal water application depth was achieved by skipping the weekly irrigation once after every other irrigation at some pre-defined stages of the crop growth. CWP were computed in terms of …Item Pathways for increasing agricultural water productivityMolden, David; Oweis, Theib Y; Pasquale, Steduto; Kijne, Jacob W; Hanjra, Munir A; Bindraban, Prem S; Bouman, Bas AM; Mahoo, Henry F; Silva, Paula; Upadhyaya, Ashutosh
