Multiannual data (2016–2018) from 12 weighed lysimeters (four soil types with textures ranging sandy loam to silt loam, three replicates) of the TERENO SOILCan network were used evaluate if evaporation (E) rates could be predicted weather using FAO Penman–Monteith (PM) method combined water flow simulations Richards equation. Soil hydraulic properties (SHPs) estimated either texture ROSETTA ped...

A study was conducted to determine the water demand of wheat crops in area around Tonna Pumping Canal. It used 2017-2018 climate data need for CROPWAT. Reference crop evapotranspiration (ETo) determined using FAO Penman Monteith method. When considering crops, four stages growth were considered: early stage, development mid-maturity, and late-maturity stages. Crops planted 2017 rabi season yiel...

El trabajo se desarrolló con el objetivo de comparar los valores evapotranspiración obtenidos a partir cuatro métodos indirectos empíricos en localidades interés agrícola la provincia Holguín. Fueron utilizados datos medios mensuales las estaciones meteorológicas La Jíquima, Guaro, Pinares Mayarí y Velasco. Los aplicados fueron Hargreaves, Hargreaves Samani, Thornthwaite Blaney-Criddl...

coriandrum sativum l. is one of the most important plants compared to the other herbs and medicinal plants as a planted covered area in kermanshah province. for a suitable irrigation management programming, the awareness of crop coefficient and water requirement in different plant stages is essential. the ratio of actual evapotranspiration to reference crop evapotranspiration is defined as crop...

Crop coefficient for cherries was evaluated by measure the water consumption in Michigan State to find its variation with time as plant growth. coefficients value (Kc) were predicated University (MSU) and also Food Agriculture Organization (FAO) according consume of through season. In this paper crop are modified accordingly actual measurements soil moisture content. Actual evapotranspiration (...

Abstract. Canopy stomatal conductance is commonly estimated from eddy covariance measurements of the latent heat flux (LE) by inverting Penman–Monteith equation. That method ignores sensible (H) and instead calculates H implicitly as residual all other terms in site energy budget. Here we show that canopy more accurately calculated (EC) both LE using flux–gradient equations define underlie equa...

In the current investigation, evaporation and transpiration potential were also estimated by means of FAO Penman- Monteith evapotranspiration estimation method and Deviation from Optimum Percentage (DOP) technique by climatic elements (min-max temperature, relative humidity, wind speed and radiation) during at least 10 years statistical period regarding sunflower phenological conditions in Kurd...

The FAO 56 Penman–Monteith equation (PM) is considered the most accurate method for estimating reference evapotranspiration (ETo). However, PM requires a large amount of data that not always available. Thus, objective this study to improve Hargreaves–Samani (HS) estimates in Peruvian Altiplano (PA) by calibrating radiation coefficient KRS. results show modified HS (HSM) ETo at validation after ...
