Tobacco is an important cash crop which is affected by different diseases in different stages of life cycle. For the control of these diseases different pesticides are used. In the present study, Speight G-28 of FCV (Flue Cured Virgin) was grown in the experimental beds to evaluatethe effect of different fertilizers (i.e., Di Ammonium Phosphate, Ammonium Nitrate, Nitrophas, Super Phosphate, FYM and control) on the incidence of damping-off disease in tobacco nursery. Results showed the maximum disease was occurred in FYM (Farm Yard Manure) treated beds followed by super phosphate and the minimum disease were reported in DAP (Di Ammonium Phosphate) treated beds and followed by Nitrate. FYM was the primary source of infection causing damping-off disease. It was known that for the control of damping off disease there were many factors which were correlated to each other e.g. temperature, moisture, and soil nutrient. It was also observed that no seedlings were emerging in bed containing urea fertilizer due to ammonia gas formation which suppresses the seeds to germinate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
