this study was conducted to evaluate the impact of deficit irrigation and growth stages on yield and yield components of potatoes and water use efficiency. a field experiment was conducted at shahrekord agricultural research station over three years of crop seasons using a randomized complete block design with three replications. plots were assigned to five levels of deficit irrigation treatmen...

abstract due to limited water resources and occurrence of recent droughts, the use of new management and planning methods for optimal irrigation scheduling of agricultural crops is inevitable. present of appropriate mathematical and dynamic relationship between yield, evapotranspiration and water use efficiency parameters is the first and most important step in the optimal management of irrigat...

Under surface irrigation, particularly in clay soils cut-off technique is considered as one of the most practical way in saving irrigation water that traditional farmers could be easily implemented. Such farming way is processing through find out the optimum length of irrigation run at which watering should be stopped instead of irrigation till the tail end of the furrows or borders. Such proce...

Despite of the water use increment for other sectors than agriculture, the water use for irrigation is the main water consumer in global scale. However, irrigation has been pressured by the civil society to improve water use efficiency in agriculture, to prevent water scarcity for human population that grows continuously, mainly in developing areas of the planet. On the other hand, the irrigati...

To minimize movement of tritium into surface waters at the Mixed Waste Management Facility at the Savannah River Site, tritiumcontaminated groundwater released to the surface along seeps in the hillside is being retained in a constructed pond and used to irrigate forest acreage that lies over the contaminated groundwater. Management of the application of tritium-contaminated irrigation water ne...

sugarcane, which has high water requirements, is grown in khuzestan province (iran). climate and optimizing the use of water is very important to sustainable cultivation of sugarcane. studies of water requirements for sugar cane in khuzestan show that in parts of sugarcane agro-industry, the water applied is more than the actual water requirement of the plant. the present study was conducted to...
