A layer of harvest residues from the previous crop can reduce wasteful evaporation from the soil surface and thereby increase the efficiency of use of limited water resources for agricultural production. The practice of harvesting sugarcane green and leaving crop residues in the field, as opposed to burning the residue, has been re-adopted in many sugarcane industries worldwide. However, a bett...

Abstract Optimization of water use for irrigation will only be possible with the adjustment management, which is directly related to correct estimate actual evapotranspiration crop. The present study aimed evaluate different mathematical approaches used in estimating a new soybean cultivar (BRS 7581RR) subjected deficit conditions. For this, ETa estimated by FAO56 Dual, Jensen and Hermann, Aqua...

The standardized FAO56 Penman-Monteith model, which has been the most reasonable method in both humid and arid climatic conditions, provides reference evapotranspiration (ETo) estimates for planning and efficient use of agricultural water resources. And sensitivity analysis is important in understanding the relative importance of climatic variables to the variation of reference evapotranspirati...

Modified Bellani plate atmometer has been offered as an alternative and simpler technique to combination-based equations to estimate evapotranspiration ~ET! rate from green grass surface. However, there is a lack of information on its’ accuracy in humid climates. The evaporation rate sEAd from one type of atmometer marketed under the brand name ETgage® ~or ETG! with a Number 30 green canvas cov...

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...
