Cv. PBNC-1 was conducted during 2016- 2017, at Instructional-cum-Research Farm, ·nepatiment of Horticulture, College of Agriculture, Latur, VNMKV, Parbhani with object to study the effect of plant growth regulators on growth, yield and quality of chilli var.PBNC-1. The experiment consists of eight treatments consisting viz. NAA@ 25 and 50" ppm, GA3@ 10 and 20 ppm, 2,4-D@ 5 and 10 ppm, Ethephon@ 50 and 100 ppm, Paclobutrazol@ 10 and 20 ppm, CIPA@ 20 and 40 ppm, Alar@ 50 and 100 ppm and control ( water spray). The experiment was laid out in Randomized Block Design with three replications. The observations on srowth attribute~ viz. height of.plant, number of branches per plant, spread of plant and stem girth, : Effect on flowering viz. days required to first flowering, days required to 50% flowering and days to first harvesting.: effect on fruits viz. length of fruit, diameter df fruit, pericarp thickness, fruit stalk length, weight of seed per fruit and seed recovery percentage.: effect on quality viz. fruit colour, fruit shape, fruit texture and seed colour.: effect on yield attributes viz. number of fruits per plant, weight of fruit per plant, yield per plot and yield per hectare.: effect on insect pest incidence were recorded. Significantly maximum height of plant (83 .13cm), number of branches . 2 per plant (19.07), spread of plant (793.67cm ) and stem girth (4.38cm) were recorded by the foliar application ofNAA@ 25 and 50 ppm, respectively. The minimum days to first flowering, days to 50% flowering and days 0 to first harvesting recorded by foliar application of Ethephon@ 50 and 100 ppm. The maximum length of fruit, diameter of fruit, pericarp thickness, fruit stalk length, weight of seed per fruit and seed recovery percentage were obtained by application ofNAA@ 25 and 50 ppm. The minimum incidence of insect and pest recorded by application of2, 4-D@ 5 and 10 ppm. Present investigation indicated that, the highest yield ( q/ha) and B: C ratio with good quality of chilli fruit should be obtained by foliar application of NAA@ 25 and 10 ppm.EnglishThesis
