  • Effects of Sprinkler Irrigation System and Water Use Efficiency (WUE)
    International Journal of Modern Agriculture, Volume 10, No.1, 2021 ISSN: 2305-7246 Effects of Sprinkler Irrigation System and Water Use Efficiency (WUE) Gaurav Kumar1 1 Department of Agriculture, Sanskriti University, Mathura Uttar Pradesh-281401, India. Corresponding author: N. N. Saxena Department of Agriculture, Sanskriti University, Mathura Uttar Pradesh-281401, India. Abstract Although the population of Egypt is over ninety million, It is unable to fulfill the food requirements as enough amount of water is not available for sufficient production of crops. In order for recognizing and implementing the steps to minimize water usage and improving the crop production techniques, this research is carried out into the farm fields of farmers in 2009 and 2010, 2010 and 2011 to evaluate the effectiveness and economy feasibility of the sprinkler irrigation system for the growth of the wheat crops. In the National Researches Centers and Development Station in Nubaria, two field studies were performed. Under sprinkler irrigation method the water related characteristics of the crops like wheat have been readied in the region. Treatments composed of two irrigation sprinklers, set sprinklers (S1) and the lateral hand motions (S2), and 3 levels of irrigation (IF1: only once in a whole week; IF2: only twice in the whole week, IF3: three times in a whole week). Also, the highest amount of net profit occurred under strong defined sprinkler irrigation scheme and irrigation size. The suggested sprinkler method and irrigation schedule for each case for winter wheat in the Nubaria is solid set sprinkler (S1) and three-fold irrigations per week (IF3). The method of sprinkler irrigation is most general method of adaptation of irrigation water that normally falls as rainfall.

  • Tips for Irrigation Sprinkler Systems Tune-Up Checklist
    Town of Lincoln Water Department Tips for Irrigation Sprinkler Systems Tune-Up Checklist __________________________________________________________________ There is no better time than spring to make sure your automatic sprinkler system is ready for another season of efficient lawn and garden watering. Here are a few simple steps that will go a long way towards saving water and money. The most important thing to remember when turning on your sprinkler system is to turn on the water slowly. You can create a huge water hammer if you are not careful. A water hammer is a high-pressure surge that occurs when a valve is first opened. An initial pressure surge can result in pipe bursts and damaged valves. When restoring water to your sprinkler system, open the main water valve slowly to allow pipes to fill with water in a gradual and controlled manner, thus preventing a water hammer and costly damage. Always open the system shutoff valve slowly to let the system pressurize gradually. 1. Starting your sprinkler system while the ground is still frozen can result in damage to the pipes. Use a shovel to make sure that the soil is frost-free 12 inches deep. If it is still solid as a rock, then wait another week and test it again before starting the sprinkler system. 2. Run a check of the irrigation controls and programs. Make sure the date and time is correct, and that the settings are appropriate for your landscape’s watering needs. Keep a copy of your watering schedule nearby. 3. Check for debris that may block the flow of water from the sprinkler heads.

Irrigated areas will increase in forthcoming years, while fresh water supplies will be diverted from agriculture to meet the increasing demand of domestic use and industry. Furthermore, the efficiency of irrigation is very low, since less than 65 % of the applied water is actually used by the crops. Worldwide water management in irrigated and rain-fed agriculture is becoming more and more complex to overcome the expected water scarcity stress. The sustainable use of irrigation water is a priority for agriculture in arid areas. So, under scarcity conditions and climate change considerable effort has been devoted over time to introduce policies aiming to increase water efficiency based on the assertion that more can be achieved with K e yw or ds less water through better management.
