Observational Stations, year data use and site characteristics
For Karnal were used data cropped seasons for Hisar, Karnal, Rewari and Rewari were used for development of multiple regression models, those parameters were significant influence after taking the statically analysis. The collaborative experiments were performed between Department of Plant Pathology and Agricultural Meteorology, CCS HAU, Hisar. The Karnal bunt diseases in percentage (%) analyzed and weather parameters and its analysis performed by Department of Agril. Meteorology. The frequency or number seasonal analyzed Karnal bund diseases were use (n) number were varies according the data availability and diseases severity was found during the course of study.
