Evapotranspiration is an important parameter to evaluate soil water deficit and use efficiency, especially in locations with irregularly distributed precipitation. The aim of this study was assess the daily actual evapotranspiration (ETa) estimated by Thornthwaite Mather balance adapted for crops (ThM) dual Kc method crop coefficients optimized from inverse modeling adjustment suggested FAO-56 ...

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...

Agro-hydrological models have increasingly become useful and powerful tools in optimizing water and fertilizer application, and in studying the environmental consequences. Accurate prediction of water dynamics in such models is essential for models to produce reasonable results. In this study, detailed simulations were performed for water dynamics of rainfed winter wheat and barley grown under ...

The accurate estimation of reference crop evapotranspiration (ETO) plays an important role in guiding regional water resource management and content research. In order to improve the accuracy ETO prediction regions with missing data, this study used partial correlation analysis method select factors that have a large impact on as input combinations construct models for typical stations semi-ari...

Bu çalışmada, Akdeniz iklim koşullarında yetiştirilen kinoanın su-verim ilişkileri, bitki su tüketimi ve katsayılarının (Kc) belirlenmesi amaçlanmıştır. Araştırma drenaj tipi lizimetre sisteminde, kumlu tın bünyeli toprakta, 2017 yılında, Titicaca (Q-52) kinoa (Chenopodium quinoa Willd.) çeşidinde yürütülmüştür. Araştırmada tam sulama (TS), sırasıyla %75, 50 25 oranında kısıntılı (KS75, KS50, K...

The rapid decline of groundwater resources in South Asia due to excessive irrigation during dry season requires awareness optimal on-field water requirements. Such information is currently provided on farmer cellphones through an operational Irrigation Advisory System (IAS). To minimize the cost sending such advisory texts farmers while maximizing impact IAS sustainability, we integrated Gravit...

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...

Drought is one of the most severe natural disasters worldwide, but with a particular emphasis in sub-humid and semi-arid climates. Several indices have been created to appropriately identify drought’s characteristics variability. The main objectives this study consisted analyzing behavior different applied northeast Algeria comparing them across long-term data set (1961–2014). SPI RDI at 9-mont...
