Estimation 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 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 Reference Evapotranspiration Using Artificial Neural Network Models and the Hybrid Wavelet Neural Network
Estimation of evapotranspiration is essential for planning, designing and managing irrigation and drainage schemes, as well as water resources management. In this research, artificial neural networks, neural network wavelet model, multivariate regression and Hargreaves' empirical method were used to estimate reference evapotranspiration in order to determine the best model in terms of efficienc...
متن کاملestimation of reference evapotranspiration in greenhouse by artificial neural network
nowadays artificial neural networks (anns) are being applied in several problems of water engineering where there is no clear relationship between effective parameters on the estimation of phenomenon. this research was used to measure aerodynamic data inside and outside greenhouse for estimating reference evapotranspiration in greenhouse by using anns. ann was used with perceptron multilayer st...
متن کاملEstimation Of Reference Crop Evapotranspiration Using Fuzzy State Models
Daily evapotranspiration (ET) rates are needed for irrigation scheduling. Owing to the difficulty of obtaining accurate field measurements, ET rates are commonly estimated from weather parameters. A few empirical or semi–empirical methods have been developed for assessing daily reference crop ET, which is converted to actual crop ET using crop coefficients. The FAO Penman–Monteith method, which...
