KANWAR, H.S.MANOHAR, LAL2016-11-152016-11-152013http://krishikosh.egranth.ac.in/handle/1/85688ABSTRACT The present investigations entitled “Studies on planting density and training on seed production of bell pepper (Capsicum annuum L.) under protected conditions were carried out using cv. Solan Bharpur. The experiment was laid out in Randomized Block Design (Factorial) in the field and in Completely Randomized Block Design (Factorial) in Laboratory with four replications of each treatment combination in both the experiments at Seed Technology and Production Center, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during Kharif 2012. The treatment combinations comprised of three planting densities (S) viz., S1 (45x15 cm), S2 (45x30 cm) and S3 (45x45 cm) and four training levels (T) viz., T1 (single shoot), T2 (two shoots), T3 (three shoots) and T4 (four shoots). The observations were recorded in the field on plant height (cm), days to ripe fruit harvest, powdery mildew severity, ripe fruit weight (g), ripe fruit length (cm), ripe fruit width (cm), number of ripe fruits/plant, ripe fruit yield per plant (Kg), number of seeds/fruit, per cent seed recovery, seed yield/plant (g), seed yield/m2 (g), seed yield/ha (Kg), 1000 seed weight and benefit: cost ratio. While the observations recorded in the laboratory were germination (%), seedling length (cm), seedling dry weight (mg), seedling vigor index-I & II. Analysis of variance showed significant differences among the treatment combinations for all the characters studied except percent seed recovery. The combination S2T2 (plants spaced at 45x30 cm and trained to two shoots) was found superior over all other treatments in terms of economic characters such as total fruit yield/plant, seed yield (per plant, per m2 and per hectare) and benefit: cost ratio. The treatment combination S3T1 (plant spaced at 45x45 cm and trained to single shoot) performed best for many fruit and seed characters but it gave lower seed yield and was uneconomic. Therefore, planting density 45x30 cm in combination with two shoot training system i.e. S2T2 can be recommended for commercial seed production of bell pepper.enplanting, yields, fruits, spacing, biological phenomena, sowing, vegetables, pepper, developmental stages, research methodsseed production , bell pepper (Capsicum annuum L.)Thesis
