| dc.description.abstract | Field experiment entitled “Spatio-temporal progression of yellow wheat rust in relation to weather in NW India” was conducted during rabi seasons of 2015-16 and 2016- 17 at different locations of NW India, at HAU, Hisar. The first appearance of yellow rust on 9th Jan. (2nd SMW) in Yamuna Nagar during 2015-16 and during 2016-17 the yellow rust was observed on 29th Dec. (52 SMW) in Gurdaspur station.. Disease severity was higher (70%) during rabi 2015-16 as compared to 2016-17 (60%). The maximum temperature, minimum temperature and Vapour pressure deficit were positive significant correlated whereas morning and evening relative humidity were negatively correlated with disease severity of yellow rust and rainfall had non significant correlation with disease severity. The variability in disease severity can be explained from 72 to 96 percent by minimum temperature and maximum relative humidity. The spectral indices viz., NDVI, VI, NRI and NPCI were negatively correlated with disease severity and DWSI and PSRI were positively correlated with disease severity of yellow rust at all the locations.The best fit model based on spectral indices explained the variability in disease severity of yellow rust up to 98 percent by NDVI and DWSI at Jammu, 74 percent at Gurdaspur, 94 percent at Yamuna Nagar, 95 percent at Dhaula Kuan, 97 percent at Ambala, and 92 percent at Karnal, and 99 percent at Hisar, respectively. | en_US |
