Temporal Downscaling of Crop Coefficient and Crop Water Requirement from Growing Stage to Substage Scales
Crop water requirement is essential for agricultural water management, which is usually available for crop growing stages. However, crop water requirement values of monthly or weekly scales are more useful for water management. A method was proposed to downscale crop coefficient and water requirement from growing stage to substage scales, which is based on the interpolation of accumulated crop ...
متن کاملDetermination of Crop Water Use and Crop Coefficient of Two Hybrids of Sunflower (Euroflor and Sirna) under Drip-Tape Irrigation System
The purpose of this study was to measure daily and seasonal evapotranspiration and daily crop coefficient of two common varieties of sunflower (Sirna and Euroflor) via drip-tape irrigation system. For this purpose, the sunflower water use was determined by daily monitoring of soil moisture at the depths of 10, 20, 30, 40 and 60 cm, and the crop evapotranspiration (ETC) was measured using volume...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
determination the crop coefficient and water requirement of lentil, using water balance method (case study: khorram abad)
introduction evapotranspiration is one of the most important elements of hydrological cycle which is required for water resource management and design of irrigation systems. crop evapotranspiration (etc) can be measured by the lysimeter using water balance equation. it also can be estimated by multiplying reference evapotranspiration (eto) and crop coefficient (kc). considering the importance o...
متن کاملThe Use of a Meteorological Station Network to Provide Crop Water Requirement Information for Irrigation Management
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...
