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 کاملEstimation of Potential Evapotranspiration and Crop Coefficient of Wheat at Rupandehi District of Nepal
This study is carried out to estimate the potential evapotranspiration (PET) and crop coefficient (Kc) for Wheat, BL 3235 variety. A lysimeter is installed to estimate PET at the experimental farm of Agricultural Research Center of Bhairahawa, which is located in western part of Nepal. The Blaney-Criddle formula is used to estimate the Kc for wheat. The estimated values of PET and Kc for wheat ...
متن کاملEstimation of Potential Evapotranspiration and Crop Coefficient of Maize at Rupandehi District of Nepal
This study was conducted to determine the potential evapotranspiration (PET) of maize, the crop coefficient (Kc) under full water requirement as well as the cause of decrease in maize yield. It was determined that the seasonal PET of maize is about 486.6 mm. The Kc under full water supply was found to be: 0.11, 0.35, 1.51 and 0.34 for initial, development, midseason and the late season stages r...
متن کاملEvapotranspiration Estimation Using Soil Water Balance, Weather and Crop Data
The rise in water demand for agriculture, industry, domestic, and environmental needs requires sagacious use of this limited resource. Since agriculture (mainly irrigation) is the major user of water, improving agricultural water management is essential. Efficient agricultural water management requires reliable estimation of crop water requirement (evapotranspiration). Evapotranspiration (ET) i...
متن کاملSteady and Unsteady Simulation of Lower Bari Doab Canal using SIC Model
Irrigation canal simulation models are representations of physical irrigation systems in computer which can be calibrated to simulate and optimize the actual canal hydraulics and operational conditions. This paper presents hydraulic simulation of canal reaches and structures of Lower Bari Doab Canal for effective canal management and operations to improve the performance of an irrigation system...
