ABSTRACT Many irrigation systems indicate failures with respect to their anticipated benefits. However, improvement of these schemes can be brought about through their rehabilitation. The aim of this study was to evaluate the performance of Igomelo rehabilitated irrigation scheme covering both the performance of irrigation water distribution systems and the roles of irrigators association.The scheme was divided into three reaches upper, middle and tail end. Three plots with maize, tomatoes ...
ABSTRACT This study was conducted in Kolero village in the Uluguru Mountain ranges to investigate the potential of conservation tillage on soil erosion control on steep slopes. Randomized complete block design was employed, zero and strip tillage conservation methods were practised versus the conventional shallow tillage in controlling soil erosion. The effect of using cover crops namely; lablab and cowpea were also investigated. The main crop was maize. The study area has an average slope ...
ABSTRACT Declining water resources, low rice yields and a widening gap between current rice demand and production in Zanzibar necessitates a change from the current rice production system to a more efficient system of production such as the system of rice intensification (SRI). In an attempt to evaluate the efficacy of SRI practice and determining the optimum spacing and transplanting age of seedlings for better grain yield, productive tillers and water productivity, a field experiment in a R...

ABSTRACT This study was conducted at one of the estates in Kilimanjaro Plantation to assess the performance of the drip irrigation system on coffee yield. Climatic, plant and soil factors were used for the calculation of monthly crop water and irrigation requirements and results compared with actual performance of the irrigation system. Further evaluation of the system performance was carried out using catch cans. The experiment was carried out on a 3-year-old coffee cultivar N39 at 3m spacin...
