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).
