An Agrocentric Analysis of Regional Rain Patterns as They Relate to a Rained Cotton Cropping System on the Southern High Plains of Texas

open access: yesAgriculture, 2017
Rain is the major limiter of cotton yields on the Southern High Plains of Texas. Rain can be analyzed in terms of its effect on the crop. An “agro-centric rain” analysis assesses the amounts and timing of rain events within a defined management system ...

Temporal Downscaling of Crop Coefficient and Crop Water Requirement from Growing Stage to Substage Scales

open access: yesThe Scientific World Journal, 2012
Crop water requirement is essential for agricultural water management, which is usually available for crop growing stages. However, crop water requirement values of monthly or weekly scales are more useful for water management.

Reference evapotranspiration of screenhouse‐grown crops

open access: yesActas del III Workshop en Investigación Agroalimentaria. WiA 3.1
The reference evapotranspiration Eref was measured under three screenhouses and compared to outside Eref. The reduction with respect to outside Eref was quantified by means of two factors, rad and adv. rad was found to depend linearly on transmittance (), and adv on wind ratio (). A model was proposed for screenhouse Eref based on outside weather

Prediction Accuracy for Projectwide Evapotranspiration Using Crop Coefficients and Reference Evapotranspiration

open access: yesJournal of Irrigation and Drainage Engineering, 2005
The Imperial Irrigation District is a large irrigation project in the western United States having a unique hydrogeologic structure such that only small amounts of deep percolation leave the project directly as subsurface flows. This structure is conducive to relatively accurate application of a surface water balance to the district, enabling the ...

Estimation of Evapotranspiration ETc and Crop Coefficient Kc of Wheat, in south Nile Delta of Egypt Using integrated FAO-56 approach and remote sensing data

open access: yesEgyptian Journal of Remote Sensing and Space Sciences, 2012
Crop water requirements are represented by the actual crop evapotranspiration. Estimation of crop evapotranspiration (ETc) and crop coefficient using remote-sensing data is essential for planning the irrigation water use in arid and semiarid regions ...
