The study aimed to estimate the Crop Water Requirement of Soybean plant under sprinkler irrigation system at Nasho Sector, Rwanda. Experimentally, covered total area 30mx60m give 1800m2. It means that each plot contained 10m width versus 60m height with one installed movable sprinkler. While for water collection from nozzles, catch cans were used collect discharge rate. After pumping sprinklers...

Crop coefficients are a widely used and universally accepted method for estimating the crop evapotranspiration (ETc) component in irrigation scheduling programs. However, uncertainties of generalized basal crop coefficient (Kcb) curves can contribute to ETc estimates that are substantially different from actual ETc. Limited research with corn has shown improvements to irrigation scheduling due ...

Both developing and developed countries have problems with availability of water to increase agricultural productivity. The importance of improving water efficiency in agriculture has been the subject in many research papers. The usual approach to limit water consumption in agriculture at the district and farm level is to apply water quotas. These quotas may be either for the whole season or fo...

the three practical steps that are need to be taken by government agencies in order to increase irrigation efficiency include economic motivation for optimization of water use, modification of existing irrigation systems in the short term and modernization of traditional methods in the long-term plan. the present research aims at identifying farmers' knowledge regarding irrigation and water iss...
