Nowadays, more than 155.7 thousand km of irrigation networks are operated by WUA, farms and clusters. 95% were built commissioned in the 80s last centuries. The parameters canals, 70-80s XX century, set for cotton alfalfa irrigated agriculture during growing season 170-210 days. Irrigation have been designed this crop rotation scheme. Since 1993, scheme has changed to cotton-wheat. began operat...

Upper Blue Nile Basin, Ethiopia. This study was conducted at the Koga Irrigation Scheme in upper basin (Ethiopia) to investigate influence of irrigation activity on groundwater system. Representative samples six shallow wells irrigated fields and four adjacent non-irrigated (rain-fed agricultural lands) were selected. Dipmeter hand GPS (GARMIN 60) used for monitoring water table depth fixing lo...

The remotely sensed data from an unknown location is transmitted in real time through internet and gathered in a PC. The data is collected for a considerable period of time and analyzed in PC as to assess the suitability and fertility of the land for establishing an electronic plantation in that area. The analysis also helps deciding the plantation of appropriate plants in the location identifi...

-Water plays an important role in everyday’s life. Agriculture is a backbone of our country and it uses 85% of available fresh water for irrigation. Irrigation is the method of supplying the water to the plants artificially. In India, Farmers follow different irrigation systems to cultivate the crops. The different types of irrigation methods include sprinkler irrigation, drip irrigation, surfa...

In both Australia and Swaziland large areas of sugarcane rely on irrigation to produce a viable crop or to improve rainfed productivity. Matching water supply to crop demand is essential for productivity and sustainability in any irrigation scheme. Historically Class-A pan evaporation was used as a basis for determining sugarcane water demand or evapotranspiration (ETc). ETc is now frequently o...

The recognized inefficiency of many irrigation systems, set up in developing countries in the past years, forced the attention to be focused on the investigation of the causes of such a failure. The diagnostic analysis, an investigation process which aims at revealing problems, causes and effects related to the relevant actors involved in the system, has been applied to the Chambo irrigation sy...

Agricultural systems pose many challenges and problems that can be formulated as optimization problems. Among these major challenges are crop selection and irrigation planning. That is, to decide on the proper set of crops to be cultivated and a proper irrigation scheme. Such decisions are made to achieve a certain objectives that typically include the maximization of net profit and/or the mini...
