Climatic Influences on Crop Water Requirements

Journal of the Irrigation and Drainage Division, 1957
Until recent years scientists knew very little about crop water requirements, rates at which different plants used water and particularly how climate influenced the water use rates of plants. In the past decade, however, water requirements of plants as influenced by climate have received considerable study and experimentation.

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 ...

Crop Water Requirement and Water Use Efficiency

2010
Irrigation water is a scarce factor in many regions. Therefore, crop water requirement has to be calculated, and irrigation systems have to be designed carefully.Knowledge of the evapotranspiration inside the greenhouse is important for successful plant growth, calculation of irrigation water consumption, and possible and economical rainwater ...

Water Requirements for Prevailing Cropping Pattern

2017
The objective of this chapter was to calculate water requirements for the prevailing cropping pattern in the five agroclimatic zones of Egypt. Weather data were collected for 2014/15 growing seasons to calculate water requirements for the studied cropping pattern for the five agroclimatic zones. BISm model was used to calculate ETo.

Crop Water Requirement and Irrigation Scheduling

2010
With increasing scarcity and growing competition for water, judicious use of water in agricultural sector will be necessary. This means that exact or correct amount and correct timing of application should be adopted. In addition, it will need more widespread adoption of deficit irrigation, especially in arid and semi-arid regions.

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.

Review on Crop Water Requirements in Ethiopia

Research and Innovation
Agriculture in Ethiopia, which is predominantly dependent on smallholder rain-fed production systems, remains highly vulnerable to climatic variability, recurrent droughts, and increasing water scarcity. Accurate estimation of crop water requirement (CWR)- the volume of water required to satisfy crop evapotranspiration (ETo) for optimal growth is ...

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 ...

Crop Water Requirements of Mature Blueberries in Florida

World Environmental and Water Resources Congress 2007, 2007
Climate-specific measures of crop water use of mature blueberry plantings could offer growers improved irrigation management. In contribution to improved irrigation management practices for Florida blueberry growers, this paper presents a crop coefficient for mature Southern highbush blueberry plants. Measures of crop water requirements were made using
