Abstract: Nutritional management of Okra yellow vein mosaic disease (OYVMD) was practiced to suppress the use of chemicals against disease. This viral disease resulted in heavy yield losses all over the world. In current research four okra varieties namely Indian rachna, Desi bhindi, Sabzpari, and Rama Krishna were grown in randomized complete block design (RCBD). Data were recorded at seven days interval for disease incidence of OYVMV that ranged between 25-50% (Table 2). Maximum disease incidence was shown by sabzpari with 50%, while the lowest disease incidence was recorded on Indian rachna with 25%. No variety showed immune response against the disease. Five treatments including 1% silicon, 1.5% silicon, 2% multi-nutrients, and 2% garlic extract including control with ten replications were implemented with the interval of 15 days after the appearance of first disease symptoms. Data was recorded fortnightly according to disease rating scale. Among these, multi-nutrients and garlic extract gave best results in minimizing the disease incidence up to 7.42% and 9.05% respectively. These two treatments also reduced the disease severity up to 1.23 to 2.00%. Silicon had negative impact on disease management as compared to other treatments. Impact of environmental factors including maximum temperature, minimum temperature and relative humidity on disease development in relation to treatments was also observed. Maximum temperature and relative humidity significantly favored the disease development but minimum temperature had no effect on the disease development. Therefore, better care should be adopted to avoid the pathogen at high temperature and humidity.
