A finalidade deste trabalho foi avaliar um termo-higrômetro digital para manejo de irrigação utilizando a equação Hargreaves, que utiliza medição da temperatura do ar estimativa evapotranspiração referência (ETo), comparando-a com Penman-Monteith FAO56, nas condições climáticas município Monte Alto - SP. O verificado no LIAP (Laboratório instrumentação, automação e processamento) FCAV/UNESP – C...

Evapotranspiration (ET) is a key variable in the hydrological cycle and it directly impacts surface balance its accurate assessment essential for correct water management. ET difficult to measure, since existing methods direct estimate, such as weighing lysimeter or eddy-covariance system, are often expensive require well-trained research personnel. To overcome this limit, different authors dev...

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...

So far, various methods have been presented for determining reference crop evapotranspiration in different parts of the world. The most popular and prestigious of them are probably the combined methods of Penman family, modified Blany-Criddle, Hargreaves - Samani and thornthwaite. Due to lack of lysimeter data in many parts of Iran, presenting an equation according to the regional condition wit...

ABSTRACT DMulching contributes to the maintenance of soil moisture at reasonable levels for crop growth. It influences water demand and irrigation time. The aim this study was estimate evapotranspiration root uptake by ‘BRS Princesa’ banana cultivar through a simple approach using some components balance within zone in bare mulched irrigated drip micro sprinkler systems. experimental design com...
