WebVegetable crop water requirements range from about 6" of water per season for radishes to 24" for tomatoes and watermelons. Precise irrigation requirements can be predicted based on crop water use and effective precipitation values. Lack of water influences crop growth in many ways. Its effect depends on the severity, duration, and time of ...
WebCrop water requirements (ETm) are between 800 and 1600 mm/growing period depending on climate and length of growing period. The variation in water requirements in each cutting interval for alfalfa is similar to that during the total growing period from sowing to harvest for other crops. The kc value is about 0.4 just after cutting, increasing ... WebCrop water requirements (CWR) are defined as the depth of water (millimeters) needed to meet the water consumed through evapotranspiration (ETc) by a disease-free crop, growing in large fields under nonrestricting soil conditions, including soil water and …
Webthe research on crop water requirements was conducted in the southeast, and few in the east-central parts of the state and other regions.
