dc.description.abstractThe present investigation was carried out to study the “Impact of plant growth regulators on growth, yield and quality of guava (Psidium guajava L.) cv. Hisar Safeda in winter season” in the Department of Horticulture, CCS Haryana Agricultural University, Hisar during 2021-22. The experiment comprised of ten different foliar treatments with three replications and were laid out in randomized block design (RBD) to assessed the effect of plant growth regulators on growth, yield and quality of guava. The results revealed that all the plant growth regulator treatments at different concentrations had significantly influenced yield, fruit development and quality parameters over absolute control. Among different treatments, for yield parameters, T6 (NAA at 100 ppm) performed better in terms of fruit set (56.73 %) whereas, T9 (GA3 at 100 ppm) observed better for fruit retention (59.85 %), fruit drop (40.17 %), no. of fruits per plant (364.52) and yield (65.49 kg/plant). Furthermore, for fruit development parameters, T9 (GA3 at 100 ppm) was found better in terms of diameter of fruit (7.23 cm), length of fruit (7.20 cm), average fruit weight (179.67 cm), average seed weight (3.21 g), fruit volume (179.22 cc). Moreover, for quality parameters, T6 (NAA at 100 ppm) performed better in terms of TSS (14.53 oB), acidity (0.31 %), TSS/Acid ratio (46.87) and sugar content i.e. total sugar (7.84 %), reducing sugar (4.63 %) and non-reducing sugar (3.21 %) while, T9 (GA3 at 100 ppm ) recorded better for pectin content (0.98 %), firmness of fruit (6.08 kg/inch) and ascorbic acid content (196.59 mg/100g pulp). However, parameters i.e. specific gravity and days to maturity were observed non-significant means all the treatments at different concentration were not significantly influenced these traits.en_US
