Abstract: A field experiment was conducted at the Horticultural Research Farm, Department of Horticulture, B. A. College of Agriculture, Anand Agricultural University, Anand during the years 2015-16 & 2016-17 with a view to study the “Effect of Pruning and Plant Growth Regulators on Fruit Yield and quality of Guava (Psidium guajava L.) cv. Allahabad Safedaâ€. The results pertaining to fruit yield and quality parameters with respect to pruning, significantly maximum shelf life (8.51, 8.57 and 8.54 days), the highest TSS (11.43, 11.46 and 11.44 0Brix), total sugar (7.78, 7.84 and 7.81 %), reducing sugar (5.13, 5.18 and 5.16 %), non-reducing sugar (2.52, 2.53 and 2.52 %), vitamin C content (179.79, 180.28 and 180.04 mg/100 g pulp) and minimum physiological weight loss (9.87, 9.17 and 9.52 %), the lowest acidity (0.75, 0.77 and 0.76 %) were recorded under 25 % shoot pruning during the years 2015-16, 2016-17 and in pooled analysis, respectively. In different plant growth regulator treatments maximum shelf life (8.64, 8.80 and 8.72 days), minimum physiological weight loss (9.19, 8.94 and 9.06 %), TSS (11.71, 11.72 and 11.74 0Brix), total sugars (8.06, 8.11 and 8.09 %), reducing sugar (5.25, 5.30 and 5.27%), non-reducing sugar (2.67, 2.68 and 2.67 %), minimum acidity (0.74, 0.76 and 0.75 %), vitamin C (181.54, 181.64 and 181.59 mg/100 g pulp) were recorded with GA3 150 mg/l during the years 2015-16, 2016-17 and in pooled analysis, respectively.
