Enhancing Water and Soil Resources Utilization via Wolfberry–Alfalfa Intercropping

Plants
The impact of the intercropping system on the soil–plant–atmosphere continuum (SPAC), encompassing soil evaporation, soil moisture dynamics, and crop transpiration, remains an area of uncertainty.

Evapotranspiration and water-use efficiency of chilli crop (Capsicum annum L.) in arid environment

Journal of Agrometeorology, 2011
Lysimetric studies on chilli crop Capsicum annum L. cv. Haripur and Raipur) were conducted at Jodhpur during three kharif seasons viz., 2006, 2007 and 2008 to determine evapotranspiration requirements during different growth stages under three ...

Evapotranspiration Partitioning in Selected Subtropical Fruit Tree Orchards Based on Sentinel 2 Data Using a Light Gradient-Boosting Machine (LightGBM) Learning Model in Malelane, South Africa

Hydrology
The accurate estimation of evapotranspiration (ET) and its components are vital for water resource management and irrigation planning. This study models tree transpiration (T) and ET for grapefruit, litchi, and mango orchards using light gradient ...

Estimation of crop water requirements: extending the one-step approach to dual crop coefficients [PDF]

Hydrology and Earth System Sciences, 2015
Crop water requirements are commonly estimated with the FAO-56 methodology based upon a two-step approach: first a reference evapotranspiration (ET0) is calculated from weather variables with the Penman–Monteith equation, then ET0 is multiplied by a ...

New Approaches to Irrigation Scheduling of Vegetables

Horticulturae, 2017
Using evapotranspiration (ET) data for scheduling irrigations on vegetable farms is challenging due to imprecise crop coefficients, time consuming computations, and the need to simultaneously manage many fields.

Parameterizing the modified water cloud model to improve soil moisture data retrieval using vegetation models

Hungarian Geographical Bulletin, 2020
The objective was to parameterize a modified water cloud model using crop coefficients (A and B). These crop coefficients were derived from Landsat-8 and Sentinel-2 data. Whereas the coefficients C and D are of soil parameters.

Are Crop Coefficients for SDI Different from Those for Sprinkler Irrigation Application?

, 2020
Highlights Crop coefficients for SDI scheduling for grain corn should be reduced by ~10% from those used for sprinkler irrigation. FAO 56 methods to calculate crop coefficients for surface drip irrigation under full-cover plastic mulch were applicable to
