todays, productivity and efficiency of irrigation have been in the center of the many water-related issues. by using sprinkler irrigation systems in addition to watering easier and automatic, that is a device for raising water application uniformity and efficiency which ultimately will save water consumption and production increase. in this study, four fixed irrigation systems of khorramabad ci...

center pivot irrigation system is used as a modern irrigation method in different parts of iran. unfortunately due to lack of proper design and hydraulic shortcomings of the system in several agricultural lands in iran, the efficiency of the center pivot irrigation system is low or unacceptable. low system efficiency results in non-uniformity of water distribution along the lateral and on the c...

introduction: designing and management of sprinkler irrigation systems depend on the situation and location of its implementation and often rely on professional and long-term tests (9). having a good irrigation system depends on knowledge of the relationship between soil, water, plants, irrigation scheduling, the required amount of irrigation water to the water-holding capacity of soil, climate...

evaluating the performance of irrigation systems by providing the possibility of increasing irrigation efficiency in those systems is an important factor in the field of water resources management. in this study, the performance of three systems were evaluated, including linear move sprinkler irrigation systems in maize, sugar beet and alfalfa fields of magsal agro-industrial company which is l...

The performances of drip irrigation systems used by farmers engaged in tomato cultivation were measured the study. For this purpose, technical performance some villages Ankara province Ayaş district Central Anatolia Region was measured. To measure systems, 4 lateral points on each manifold and dripper selected. In study, Application Efficiency (Ea) 29,5-63,6%, Uniformity Coefficient (CU) 81,4-9...

the scarcity of irrigation water and decrease of water resources are the most important limiting factors in crop production in countries such as iran. thus, studying the optimum use of water and increasing water use efficiency are essential to the agricultural sector. the use of a low pressure hydroflume has been suggested to replace traditional surface irrigation methods. the aim of this resea...
