| ABSTRACT This study’s objective was to assess the response and effectiveness of irrigation management systems for the production of bell pepper with different agricultural substrates, under protected conditions. The current study was conducted in a greenhouse located in Juazeiro, BA, in the northwest of Brazil. The experiment design was completely randomized in a split-plot system, with two irrigation treatments as the main plots (the drainage lysimeter and the Piché evaporimeter) and two substrates in each sub-plot (coconut fiber and pinus bark), with 5 replications per treatment. Harvest was conducted from 86 to 151 days after transplanting, and the following characteristics were evaluated: total, marketable and unmarketable yields, production per plant,... |

| Based on research presented in “Institutional Alternatives in African Smallholder Irrigation: :Lessons from International Experience with Irrigation Management Transfer (IWMI Research Report 60)” by Tushaar Shah, Barbara van Koppen, Marna de Lange, Madar Samad, and Douglas Merrey. An international review of IMT experiences shows that for transfer to work, the irrigation system must be central to a wealth-creating agriculture within which IMT makes good economic sense to farmers. This is not the case in a majority of Africa’s smallholder schemes. Making IMT work in this context means addressing a number of challenges: smallholder dependency resulting from years of state intervention in farm operations and management, farmers’ inability to depend on... |

| Nutrient losses in furrow irrigation runoff potentially increase when soils are amended with manure. We evaluated the effect of tillage, water soluble polyacrylamide (WSPAM) and irrigation management on runoff water quality during the first furrow irrigation on a calcareous silt loam soil, which had received 45 Mg/ha (dry wt.) dairy manure applied in the fall. In Exp. 1 the amended soil was rototilled and irrigated that fall; furrow inflows were either treated with 10 mg/L WSPAM injected into furrow inflows only during furrow advance (Fall-WSPAM), or were untreated (Fall-Control). In Exp. 2 the first irrigation on the amended soil was delayed until the following spring and treatments included rototilled WSPAM (Spring-WSPAM) and untreated rototilled... |
