The prevailed weather conditions were evaluated to take the long term
average during the 6 to 12 SMWs at four studied location of the state,
Haryana which was depicted in the Table 3. The results reveal that the
long period average in the respective weekly based weather parameters
analyzed and resulted i.e. rainfall amount varies 1.9 to 13.5 mm and 0.3
to 0.7 day, pan evaporation 2.3 to 5.8 mm, average wind speed 1.4 to
5.58 kilometer per hour, relative humidity highest and lowest obtained
(morning 69 to 92.8 % & evening 34 to 52 %) and temperature
influenced as maximum 20.8°C to 32.2 °C & minimum 6.3 °C to 15.6 °C
from 6th to 12 SMWs in the respective stations of
state, Haryana which depicted in the Table 3. The 6thto 12th SMWs weather parameters values ranged play
significant the conducive condition against for the multiplication &
development of karnal disease in the wheat seeds for the respective
locations (Table 3). The analyzed results were also seem to the waiting
period of wheat leaves, higher days of foggy weathers condition and
minimum temperature (especially during night time) quit warmers side or
warm night, that were increased the chances of infestation. The
significant parameters use to developed the regression models and then
used for the prediction of karnal bunt disease depicted in the Table 4.
