Water shortages are a continuing reality for today’s irrigated agriculture especially in the arid US southwest where cotton (Gossypium hirsutum L.) is an important crop. Decreasing water availability region coupled with high requirements inducing conservation practices, including adoption of subsurface drip irrigation (SDI) and deficit management. A 3-year study (2016, 2017, 2018) was conducted...

Crop models are important for understanding and regulating agroecosystems. Although the CERES-Wheat model is an tool winter wheat research, it has some limitations under water stress conditions. To narrow gap, this study aimed to improve performance of in arid semi-arid regions based on experimental data from 2012 2014. The Priestley–Taylor (PT) FAO56 Penman–Monteith (PM) equations were used ca...

Politicians and the general public are concerned about climate change, water scarcity, constant reduction in agricultural land. Water reserves scarce many regions world, negatively affecting productivity, which makes it a necessity to introduce sustainable resource management. Nowadays, there is number of commercial IoT systems for irrigation scheduling, helping farmers manage save water. Howev...

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...

introduction saffron (crocus sativus l.) is a subtropical plant mostly cultivated in south khorasan and khorasan razavi provinces, iran. total saffron production is about 200 ton all over the world, and since it is native to iran, the country has an important role to produce saffron. in recent years, drought showed a significant effect on water resources in birjand, south khorasan. due to lack ...

Rice culture is one of the most important crops in world, being consumed cereal grain (755 million tons 2020). Since rice usually produced under flooding conditions and water performs several essential functions for crop, estimating its needs essential. Remote sensing techniques have shown effectiveness monitoring use crop fields. An estimation from satellite data a challenge, but could be very...

The accurate estimation of reference evapotranspiration (ETref) is a crucial component for modeling hydrological and ecological cycles. goal this study was the calibration 32 empirical equations used to determine ETref in three classes temperature-based, solar radiation–based, mass transfer–based evapotranspiration. based on measurements taken between years 1990 2019 at 41 synoptic stations loc...
