Determination of crop-coefficients and estimation of evapotranspiration of rapeseed using lysimeter and different reference evapotranspiration models

open access: yesJournal of Agrometeorology, 2020
Accurate estimation of evapotranspiration of rapeseed is essentially required for irrigation scheduling and water management. The present study was undertaken during 2015-16 and 2017-18 in ICR Farm, Assam Agricultural University, Jorhat to determine ...

Shoot water content and reference evapotranspiration for determination of crop evapotranspiration [PDF]

open access: yesAfrican Crop Science Journal, 2017
Determination of water requirement for crops in resource limited areas is  challenging, yet worsened by the common assumption that all crop varieties within a species have similar water requirements. The objective of the study was to  indirectly determine crop evapotranspiration of soybean varieties, using reference evapotranspiration and shoot water ...

Prediction Accuracy for Projectwide Evapotranspiration Using Crop Coefficients and Reference Evapotranspiration

open access: yesJournal of Irrigation and Drainage Engineering, 2005
The Imperial Irrigation District is a large irrigation project in the western United States having a unique hydrogeologic structure such that only small amounts of deep percolation leave the project directly as subsurface flows. This structure is conducive to relatively accurate application of a surface water balance to the district, enabling the ...

Determination of Evapotranspiration and Crop Coefficient for Tomato by Using Non-Weighing Lysimeter in Semiarid Region

open access: yesAir, Soil and Water Research
Providing an accurate amount of water to crops based on their requirements is the primary objective of irrigated agriculture. The crop evapotranspiration and coefficient of tomato were measured using non-weighing lysimeters.

Effects on Net Irrigation Water Requirement of Joint Distribution of Precipitation and Reference Evapotranspiration

open access: yesAgriculture, 2022
To establish the uncertain influence that the joint distribution of precipitation and reference evapotranspiration has on net irrigation water requirement, a Copula function–Monte Carlo method (CFMC) was proposed to calculate the probability of ...

Estimation of Reference Crop Evapotranspiration in Northwest China [PDF]

open access: yesEarth Sciences, 2020
Based on the daily meteorological data from 1956 to 2011 in Northwest (NW) China and the Penman-Monteith (PM) equation, the regional reference crop evapotranspiration (ET0) is estimated. The ET0 variations in time series and spatial distributions are analyzed.
