چکیده
In this work, a two-source decoupling model called "STSEB" (Simplified Two-Source Energy Balance) is applied, whose purpose, through local information on air temperature, meteorology, topography, as well additional data in situ, to calculate the crop evapotranspiration multispectral and thermal images obtained from drone.The foregoing, with purpose of classifying priority irrigation areas plot almond trees being able compare results current planning water treatments by means precision agriculture instruments. At end it was possible determine that there an accuracy 75% between treatment plan administrators one application remotesensing techniques.

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...

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 Crop Evapotranspiration of Cotton using Remote Sensing Technique
Crop coefficient values are used to estimate crop evapotranspiration (ETc) for determining irrigation scheduling. Many important crop biophysical properties such as Percentage Vegetation Cover and Leaf Area Index can be estimated from remotely sensed Vegetation Index, in order to quantify real time vegetation growth dynamics. The objective of this study was to understand the effectiveness of ba...
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...
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...
