Note: Pr.: Predicted, Ob.: Observed, %D: Percentage deviation
The result reveal that shows among the station, over all predictability were ranging from -5.8 to 55.8, but higher percentage deviation was observed at Hisar and Rewari station as compared to the Sirsa and Karnal, which might be due to variability in the wheat seed disease infection and point value used in the analysis. The prediction and deviation percentage quit higher in the semi-arid agroclimatic condition of western Haryana. The results showed that these regression models predicted the Sirsa and Karnal station for the karnal bunt disease in the state within the acceptable limit (Table 5). Over prediction and higher percentage deviation were observed in the Rewari and Hisar condition, respectively. Model showed more deviation (model over and under predicted) for year 2013-14 and 2014-15 may be due to rainfall amount received above the normal from 6 to 11th SMWs. The results showed that these regression models predicted the Karnal bunt disease in the state within the acceptable limit for the year 2016-17 & 2017-18, except Sirsa station (Table 5).
