Impact of Future Climate Change on Regional Crop Water Requirement—A Case Study of Hetao Irrigation District, China

Water (Switzerland), 2017
Water shortage is a limiting factor for agricultural production in China, and climate change will affect agricultural water use. Studying the effects of climate change on crop irrigation requirement (CIR) would help to tackle climate change, from both ...

Crop Water Requirement and Utilization Efficiency-Based Planting Structure Optimization in the Southern Huang-Huai-Hai Plain

Agronomy, 2022
Optimizing planting structure that balances both high yield and water resources shortage is essential for developing efficient water-saving agriculture. To provide insights about the relationship between planting structure optimization and water resource

Crop water requirements of cotton

The Journal of Agricultural Science, 1958
1. Attention is drawn to the enormous variations in yield experienced in commercial cotton growing under rain-fed conditions. Yields at Namulonge have ranged from 161 to 1163 lb./acre.2. In seeking an explanation of this enormous variation past and present fertilizer trials in Uganda have failed to show that much of this variation is due to nutrient ...

Water Requirements for Major Crops

2015
The objective of this chapter was to calculate water requirements for four crops: wheat, maize, rice and sugarcane grown in 17 governorates in Egypt under current climate and under the A1B climate change scenario in 2040. The BISm model was used to calculate crop coefficient water depletion from root zone.

The water requirement of the mushroom crop

Scientia Horticulturae, 1974
Abstract Experiments are described in which it was attempted to quantify the water requirement of the mushroom crop for maximum yield. The amount of water applied was positively correlated with crop weight from about the second week of cropping and increasing the amount of water applied reduced the drying of the compost and casing during cropping ...

Calculation of Evapotranspiration and Crop Water Requirements

2016
Reference ET (ET0) is defined as the ET of short grass with full soil cover, and an unlimited supply of water and nutrients. In the absence of water deficit, the ET of any crop may be calculated as the product Kc x ET0, where Kc is the crop coefficient, which depends on crop related factors (leaf area, roughness) and ET0, the reference ET (grass ...

Weighing Lysimeters for the Determination of Crop Water Requirements and Crop Coefficients

Applied Engineering in Agriculture, 2006
Weighing lysimeters are accurate instruments to measure crop evapotranspiration. Three weighing lysimeters, consisting of undisturbed 1.5- ×2.0-m surface area by 2.5-m depth cores of soil, were constructed and installed at the Texas Agricultural Experiment Station in Uvalde, Texas. Two lysimeters, each weighing approximately 14 Mg, were located beneath

Crop water requirements model tested for crops grown in Greece

Agricultural Water Management, 2000
Abstract A model for estimating crop water requirements throughout crop development is presented. The model assumes horizontal uniformity and treats the two-component system of canopy and soil along the lines of Shuttleworth and Wallace (1985) . Incorporated in the model is a 3-layer soil water budget allowing evaluation of the soil surface and ...
