Abstract

Climatic data of areas where chickpea (Cicer arietinum) is grown were analyzed by stepwise discriminant analysis to identify parameters that allow a discrimination of locations with and without occurrence of Ascochyta blight (caused by Ascochyta rabiei). A discriminant function was computed, based on mean daily temperature in month 1 of the vegetation, mean precipitation in month 2, average precipitation per rainy day in months 1 and 2, and mean number of rainy days in months 1 and 2 (.)
