Abstract:
Pea (Pisum sativum L.) is the third most widely grown grain legume worldwide, commonly called as matar in Hindi and belongs to family leguminaceae. The values of Correlation coefficients among disease intensity and minimum temperature, maximum temperature, relative humidity and sunshine hours and wind velocity were -0.51, -0.60, -0.35, -0.30, 0.92 and -0.50, -0.60, -0.37, -0.30, 0.90 in protected and unprotected environments respectively. The trend of correlation was almost similar in all cultivar of pea only wind velocity showed positive correlation with all tested cultivars. The values of Correlation coefficients among disease intensity and minimum temperature, maximum temperature, relative humidity and sunshine hours and wind velocity were 0.35, 0.49, -0.57, 0.10, -0.83 and -0.24, 0.75, -0.67, 0.47, -0.17 in protected and unprotected environments respectively. The trend of correlation was almost different in all cultivars of pea except maximum temperature which showed positive correlation with all tested cultivars.
