Predicting Crop Yields with the Agricultural Reference Index for Drought

A generic agricultural drought index, called A gricultural R eference I ndex for D rought ( ARID ), was designed recently to quantify water stress for use in predicting crop yield loss from drought. This study evaluated ARID in terms of its ability to predict crop yields. Daily historical weather data and yields of cotton, maize, peanut and soybean were obtained for several locations and years in the south‐eastern USA . Daily values of ARID were...
