Title : Predicting Late Blight Severity of Potato Based on Weather Parameters in the Jammu Province

Abstract :

Epidemiological studies conducted during rabi 2018-20 revealed that weather parameters viz., maximum temperature, minimum temperature, maximum relative humidity, minimum relative humidity and rainfall were responsible for the development of late blight of potato. The primary infection of the disease initiated at 50th Standard Meteorological Week (SMW) with maximum infection rate of 0.108 on 3rd SMW. Correlation analysis showed that maximum temperature had significantly positive correlation with the intensity of late blight of potato, whereas, minimum relative humidity had significantly negative correlation. Stepwise multiple linear regression equations for two years (2018-20), revealed that the maximum temperature, maximum and minimum relative humidity and rainfall were responsible for 95.93 contribute in the disease.
