Abstract
Stripe rust caused by Puccinia striiformis f. sp. hordei is most important foliar disease of barley causing severe loss in favourable conditions. Stripe rust occurs in epidemic form in cool and moist regions. The epidemiological factors influence the incidence and severity of the crop diseases. The present study is an attempt to assess the role of weather parameters on stripe rust of barley disease development. The experiment was conducted on susceptible barley variety RD 2035 grown under five different dates of sown conditions at Rajasthan agricultural research institute, Durgapura (Jaipur) during 2016-17 and 2017-18. The weather factors (temperature, relative humidity, rainfall and sunshine hours) imparted an important role in the progression of stripe rust. Significant variations in AUDPC were observed among the crop planted at five different dates and the partial correlation was indicated that the weather factors positively correlated with the disease severity in all the planting dates. In the multiple linear regressions, the coefficient of determination was ranged from 0.59-0.77 which shows 59-77 per cent disease severity under influence of six meteorological factors. The normal sown crops were more vulnerable to stripe rust as compared to early and late sowing crops.
