Estimation of Actual Evapotranspiration, Water productivity, and Irrigation Efficiency of Wheat Fields in Surface and Sprinkler Irrigation Systems Using Remote Sensing
In arid and semi-arid regions, water resource management and optimization of applying irrigation water are particularly important. For optimization of applying irrigation water, the estimated values of actual evapotranspiration are necessary for avoiding excessive or inadequate applying water. The estimation of actual crop evapotranspiration is not possible in large areas using the traditional ...
متن کاملsugarcane irrigation scheduling by combining remote sensing data and swap model in mirza-kuchak-khan sugarcane agro-industry, ahwaz, iran
irrigation scheduling means applying the right amount of water at the right time. in this research, thecurrent irrigation scheduling implemented in the mirza-kuchak-khan sugarcane agro-industry farmslocated in ahwaz was compared with the actual sugarcane crop water requirement using swapmodel. due to lack of field measured data, the swap model was calibrated and evaluated usinglandsat 7 etm+ im...
متن کاملwater and nitrogen application levels for the optimum tomato yield and water use efficiency
this study was conducted to determine the effects of different water and nitrogen application levels on drip-irrigated tomato plants. the amount of water usage was based upon the pan evaporation from a screened (class “a”) evaporation pan. the treatments consisted of two irrigation intervals (i1= 5 days and i2= 10 days), three plant-pan coefficients (kcp1= 0.50; kcp2= 0.75 and kcp3= 1.00) and t...
متن کاملvalidation of aquacrop model for simulation of winter wheat yield and water use efficiency under simultaneous salinity and water stress
introduction: fao aquacrop model (raes et al., 2009a; steduto et al., 2009) is a user-friendly and practitioner oriented type of model, because it maintains an optimal balance between accuracy, robustness, and simplicity; and it requires a relatively small number of model input parameters. the fao aquacrop model predicts crop productivity, water requirement, and water use efficiency under water...
متن کاملMaize response to water, salinity and nitrogen levels: yield-water relation, water-use efficiency and water uptake reduction function
Water, salinity and nitrogen are the major factors affecting maize production in arid and semi-arid areas. The objectives of this study were to investigate the effects of different water, salinity and nitrogen levels on yield-water relationships, water use, water productivity (WP), water use efficiency (WUE) and water uptake reduction function by maize hybrid SC-704 in a semi-arid area and ...
