Present and Future Water Requirements for Crops

2016
In this chapter, ETo values were calculated for three studied governorates using Penman-Monteith equation, and then water requirements for the studied crops were calculated. Furthermore, the effect of climate change on ETo values were calculated after comparing between RCPs scenarios developed from four AR5 global models and its four RCPs scenarios ...

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 ...

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 ...

Water Requirement of Rice Crop in Madras

Madras Agricultural Journal, 1965
A brief review of the irrigation experiments on rice conducted in Madras Stato is prosented. These experiments dealt with four aspects of the water requirement of rice i.e., intensity, frequency and quantum of irrigation water and the duty of water for rice crop in project areas.

TOWARDS ONE-STEP ESTIMATION OF CROP WATER REQUIREMENTS

Transactions of the ASABE, 2006
This article provides theoretical analyses that facilitate the use of the Penman-Monteith equation to make a one-step estimate of crop water requirements. Reluctance to using a one-step estimate results from two outstanding issues, both of which are addressed.

Crop Water Requirements and Irrigation Efficiencies in Egypt

2017
Water scarcity is the major factor that limits the ambitious hopes to expand and increase the agricultural area to meet the present gap between food production and consumption. In areas like Egypt, located in an arid/semiarid region, where vegetation water requirement represents an important fraction of the total water consumption, the pressure of ...
