Abstract

The field-grown cultivar NAUDA-1 showed associations with a number of meteorological characteristics based on weekly assessments of anthracnose intensity. Significant positive connections were found in the correlation matrix between sunshine hours (0.5286) and maximum temperature (0.0094). On the other hand, there were notable negative connections found with wind speed (-0.8334), rainfall (-0.4883), relative humidity (-0.8108), and minimum temperature (-0.9339). The development of anthracnose was significantly influenced by the combination of these meteorological conditions. The variables that showed the greatest influence in positively influencing the intensity of anthracnose were the maximum temperature and the number of sunshine hours. Furthermore, in comparison to other metrics, the maximum temperature, relative humidity, and number of sunshine hours were found to be significant factors in the development of disease. This emphasises how intricately meteorological patterns interact to affect the anthracnose development in cv. NAUDA-1.
