dc.description.abstractThe present investigation entitled “Studies on effect of Gibberellic acid and Naphthalene acetic acid on fruit quality and yield of apricot ( Prunus armeniaca L . ) under hilly conditions ”was carried out in Fruit orchard, College of Horticulture, V. C. S. G. Uttarakhand University of Horticulture and Forestry, Bharsar, during 2015- 2016. In this study the different concentration of GA3 and NAA at different time with Randomized Complete Block Design and three replications.The different parameters for this concentration, at different time of spray were recorded to evaluate the best concentration of GA3 and NAA at different time of spray. Concentration of GA3 10 ppm + NAA 10 at full bloom stage ppm had maximum fruit set, fruit yield, size, weight and days taken to ripening (60.59 %, 26.33 kg, 2.14 cm x 2.61 cm, 22.33 g and 75 days) was recorded. While in pea stage the concentration of GA3 15 ppm + NAA 10 ppm had maximum fruit set, yield, size, weight, volume and days taken to ripening (66.64 %, 25.66 kg/tree, 2.85 cm x 2.99 cm, 28.1g, 31.36 cm3/fruit and 79 days) was recorded. And in chemical parameters highest titrable acidity (1.18%) content was recorded in control. The highest total sugar and non reducing sugar (21.11 % and15.69%) and ascorbic acid content (12.11 %) was recorded in GA3 15 ppm + NAA 10 ppm at pea stage. Hence, the different concentrations of GA3 and NAA at different time of spray varied in their quality and yield characteristics. The treatment GA3 10 ppm + NAA 10 ppm at full bloom stage and treatment GA3 15 ppm + NAA 10 ppm was the best concentrations of GA3 and NAA at pea stage where good quality fruit and good yield of apricot were observed.en_US
