Correcting Midseason Crop Coefficients for Climate

Journal of Irrigation and Drainage Engineering, 2015
AbstractIt is well known that crop coefficients are not necessarily transferrable from one location to another, for a variety of reasons.

CROP COEFFICIENTS IN SIMPLIFIED HYDROPONIC SYSTEMS

Acta Horticulturae, 2006
This study was carried out during the spring growing season of 2003 in order to determine tomato crop evapotranspiration and to develop crop coefficients under different irrigation treatments in open and closed systems. The experiment was conducted in a non-heated plastic covered greenhouse.

Crop coefficients of major crops in South India

Agricultural Water Management, 1994
Abstract Crop coefficients (Kc) were estimated for cotton, sorghum and millet for tropical South India based on lysimeter measured actual evapotranspiration (ET) and reference crop ET computed by the modified Penman method. The estimated crop coefficients were 0.46, 0.70, 1.01, and 0.39 in the four crop stages for cotton.

Crop Coefficients: A Literature Review

Journal of Irrigation and Drainage Engineering, 2016
AbstractRecently presented climate change scenarios include increasing demand for water, due to both increase in temperature and variations in precipitation pattern.

Crop coefficients for peanut evapotranspiration

Agricultural Water Management, 1988
Abstract Meteorological and soil moisture data were collected from field sites in Caddo County, Oklahoma, during the 1984 and 1985 irrigation seasons. Analysis of alfalfa (Medicago sativa L.) water use data enabled calibration of the modified Penman equation for reference crop evapotranspiration ( et ).

Crop Coefficients for Drip-irrigated Processing Tomatoes

2004, Ottawa, Canada August 1 - 4, 2004, 2004
Efficient management of drip irrigation systems requires reasonable estimates of crop evapotranspiration (ET), normally calculated as the product of a crop coefficient and a reference crop ET. However, a review of literature revealed mid-season crop coefficients of processing tomatoes to range from 1.10 to 1.25.

Crop Coefficients of Some Selected Crops of Andhra Pradesh

Journal of The Institution of Engineers (India): Series A, 2015
Precise information on crop coefficients for estimating crop evapotranspiration (ETc) for regional scale irrigation planning is a major impediment in many regions. Crop coefficients suggested based on lysimeter data by earlier investigators have to be locally calibrated to account for the differences in the crop canopy under given climatic conditions ...
