At present and more so in the future, irrigated agriculture will take place under water scarcity. Insufficient water supply for irrigation will be the norm rather than the exception, and irrigation management will shift from emphasizing production per unit area towards maximizing the production per unit of water consumed, the water productivity. To cope with scarce supplies, deficit irrigation,...

Surface irrigation is the dominant method of on-farm irrigation in Egypt as well as world wide. Furrow watering is considered as one of the main types of surface irrigation. Most of the cultivated crops are grown under such type of watering. The principal advantage of furrow irrigation is the less irrigated area comparing with that under basin irrigation which equaled total cultivated acreage. ...

To improve the management of irrigation district is a key to develop water-saving agriculture. Based on the basic principles of water-saving irrigation, and using the method of Modified Penman Monteith and water balance equation, The system of irrigation management and decision support based on WEBGIS was developed,which is according to the soil moisture, crop growth status, meteorology change ...

Plastic mulch and drip irrigation are commonly used in high intensity vegetable production regions such as Florida. Drip irrigation can be much more efficient than sprinkler irrigation since only the root zone of the cropped area is irrigated. However, improper irrigation management can lead to wasted water and leaching of soluble chemicals such as nitrate. In this project, several irrigation t...

Drip irrigation can reduce water and fertilizer use; however, the frequency of topdressing required for drip wheat in Huang-Huai-Hai region is still unclear. Through two continuous season field experiments, yield related traits under traditional surface (border irrigation) three fertilization frequencies (DF2, DF3, DF4, that was, twice, or four times same way during growth period) cultivars (Ji...

Many factors affecting irrigation model, including irrigation water volume, crop water requirement, production function of irrigation water, rainfall, soil water balance, water sensitive index in different stages of crop growth, the grain market price, irrigation water price, minimum yield, irrigation cost etc are considered. Then a multi-constraints and non-linear optimization irrigation model...
