Estimativa da Evapotranspiração de Referência Padrão (Penman-Monteith FAO 56): Uma Abordagem com Dados Meteorológicos Limitados [PDF]

Nativa, 2016
A agricultura irrigada é uma atividade que demanda grandes volumes de água. Neste sentido, o conhecimento das necessidades hídricas das culturas (evapotranspiração da cultura, ETc) assume fundamental importância no volume de água a ser aplicado. A ETc pode ser estimada a partir da evapotranspiração de referência (ETo) e do coeficiente da cultura (Kc ...

Diversification and intensification of irrigated maize‐based cropping systems under Mediterranean conditions

Agronomy Journal, Volume 118, Issue 1, January/February 2026.
Abstract Under Mediterranean irrigated conditions cover cropping (CC) and double cropping (DC) are diversification/intensification strategies that can increase grain yield and resource use efficiency of the traditional winter fallow‐maize (Zea mays L.) system.

Estimation of Monthly FAO Penman-Monteith Evapotranspiration in GIS Environment, through a Geometry Independent Algorithm

Agriculture and Agricultural Science Procedia, 2015
AbstractThe purpose of this study was to implement the monthly FAO Penman-Monteith evapotranspiration estimation method in a GIS environment, given the importance of spatial estimation of the evapotranspiration in the rational management of water resources and also the lack of easily applicable methodology in GIS environment.

Effects of barley‐pea intercropping on soil carbon, crop productivity, and grain quality in a low‐input temperate agroecosystem

Agronomy Journal, Volume 118, Issue 1, January/February 2026.
Abstract Intercropping has the potential to help adapt arable agriculture to climate change, but its effects on soil carbon and crop production in temperate agroecosystems remain uncertain. This study examined the effects of temperate intercropping systems on soil carbon and crop productivity.

Sensitivity of FAO Penman–Monteith reference evapotranspiration (ETo) to climatic variables under different climate types in Nigeria

Journal of Water and Climate Change, 2020
AbstractUnderstanding the impact of changes in climatic variables on reference evapotranspiration (ETo) is important for predicting possible implications of climate change on the overall hydrology of an area. This study aimed to determine the effects of changes in ETo with respect to changes in climatic variables.

Estimation of Reference Evapotranspiration using the FAO Penman-Monteith Method for Climatic Conditions of Poland

, 2011
Evapotranspiration is the combination of soil evaporation and crop transpiration. Weather parameters, crop characteristics, management and environmental factors affect evapotranspiration. Reference, potential and actual evapotranspiration are distinguished. These terms are commonly used, although some differences of their definitions can be found among

FAO crop coefficient and plant‐available water: Do soil and plant hydraulic properties matter?

Agronomy Journal, Volume 118, Issue 1, January/February 2026.
Abstract How to ensure that “the availability of soil water does not limit plant growth or transpiration?” Determining the so‐called crop coefficient (Kc) relies on this assumption of optimal or non‐limiting soil water conditions, which, in turn, is understood as the soil water content at field capacity, a parameter with, de facto, no relation to ...
