S. Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.) during 2015. The hot water seed treatment comprised of different ranges of temperature (47-49, 50-52 and 53-55 °C) and different duration of time (30, 45 and 60 min.). Under in vitro conditions, the hot water treated seed with temperature (50-52) °C for 30 minutes (T2D1) showed maximum germination (90.75 %), seedling length, seedling dry weight, seed vigour index-I, seed vigour index-II and lower seed microflora (%) as compared to untreated seed (control). In nursery condition, the hot water treated seed same temperature (50-52) °C for 30 minutes (T2D1) showed maximum values w.r.t. total emergence (87.78 %), seedling height, seedling dry weight, seed vigour index-I, seed vigour index-II and lower damping-off incidence as compared to control with 52.88 % post emergence damping-off and 23.33 % virus incidence. Under protected condition the hot water treated with this temperature (50-52) °C for 30 minutes (T2D1) showed maximum values w.r.t. plant height, average fruit length, number of fruits per plant, fruit yield per plant and fruit yield per ha. This treatment also resulted minimum days to first marketable picking, maximum harvest duration and less resulted incidence of diseases like anthracnose, cercospora leaf spot, wilt and virus as compared to control. Hot water seed treatment at (50-52) °C for 30 minutes (T2D1) proved effective in increasing growth, yield and reducing the incidence of diseases like damping–off, anthracnose, cercospora leaf spot and viruses in bell pepper cultivar Solan Bharpur. However, further studies are needed to standardize the required temperature for controlling other seed borne microflora to extend the wide use of hot water seed treatment for production of healthy crop of bell pepper.en<h1>You have exceeded your usage quota.
