this study was carried out to determine the best rotation with using plants as wheat, soybeans, canola and tomatoes for field planting area of 35 hectares, in 15 kilometers northwest of galikesh in 2010. to this end, by using the cropwat software, appropriate model was selected in terms of net profit and performance (output per unit of water used), in irrigated and rain fed conditions. accordin...

measuring sensitivity of hydraulic structures is considered as an approach for evaluation of water projects performance, due to lower distribution efficiency in irrigation and drainage project schemes. sensitivity analysis approach for irrigation structures is one of flow analysis methods which are developed in recent years in order to measure the behavior of flow in hydraulic structures in an ...

Abstract Rapid urbanization, pollution, and increasing water consumption together with climate change necessitated to process of more effective measurement, management, decision mechanisms on regional resources. The concept footprint (WF) is a parameter that has been introduced the scientific literature in recent years similar ecological carbon footprints. WF any field or product refers total v...

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...

A study on evapotranspiration for wheat was conducted in the two-year Rabi season crop from November, 2017 to April, 2018 and April 2019 at Gaya District, Bihar. Spatio-temporal information actual (ETa) helps users better understand evaporative depletion establish links between land use, water allocation, use. The Surface Energy Balance Algorithm Land (SEBAL) adopted employing essential adaptat...

Agricultural production is an activity of high economic and environmental risk, nowadays especially. Handling of widening scientific knowledge and up-to-date technological appliances needs rethinking of foregoing theory and practice; according to some researchers, total paradigm change is needed. The “sustainable development” theory of Agenda 21 made up by the Rio Summit (1992) means long-term ...
