 ABSTRACT

The survey was conducted during Rabi seasons of 2015-16 and 2016-17 at different locations of NW India, at HAU, Hisar. Yellow rust severity was recorded at 15 days intervals. Disease severity was higher (70%) during Rabi 2015-16 as compared to 2016-17 (60%) during both years (Pooled data). The maximum temperature, minimum temperature and Vapour pressure deficit were positively correlated whereas morning and evening relative humidity were negatively correlated with average disease severity and rainfall had non significant correlation with disease severity. The variability in disease severity can be explained from 83 to 99 percent by minimum temperature and maximum relative humidity.
