dc.descriptionThe investigation was carried out to evaluate the effectiveness of different combination of GA3 and pruning on Assam lemon. It was carried out on 5 years old trees of uniform size at the Fruit Research Farm, Department of Fruit Science, College of Horticulture and Forestry, Pasighat, Arunachal Pradesh in the year 2015-2016. The experiment was laid out in Factorial Randomized Block Design with 10 treatments replicated 5 times. The treatments tried were, G1P1-GA3 50 ppm single spray + 15 cm shoot pruning, G1P0-GA3 50 ppm single spray + No pruning, G2P1-GA3 100 ppm single spray + 15 cm shoot pruning, G2P0-GA3 100 ppm single spray + No pruning, G3P1-GA3 50 ppm double spray + 15 cm shoot pruning, G3P0-GA3 50 ppm double spray + No pruning, G4P1-GA3 100 ppm double spray + 15 cm shoot pruning, G4P0-GA3 100 ppm double spray + No pruning, G0P1-No GA3 + 15 cm shoot pruning, G0P0-No GA3 + No pruning,en_US
dc.description.abstractExperimental fallout revealed that the imposition of different treatments and had a significant effect on growth, flowering, yield and quality parameters of the fruit. Highest increase in plant height (29.20 cm), yield per tree per season of winter (5.28 kg), yield per plant (10.19 kg), yield per ha (11.32 t), fruit weight (121.92 g), fruit length (10.14 cm), fruit juice of winter (48.20 ml), TSS of summer (7.40 0Brix) and winter (7.50 0Brix), ascorbic acid of winter (49.94 mg/100g) and total sugar of winter (2.00%) were recorded by G1P1, i.e., (GA3 50 ppm single spray+15 cm shoot pruning) it also lowers titratable acidity of winter (3.67%). Whereas G3P1 i.e., (GA3 50 ppm double spray+15 cm shoot pruning) recorded highest canopy spread (0.73 m3), number of fruitlets per branch (6.95) and it increases fruit juice of summer (45.20 ml), reducing sugars of winter (1.79%), ascorbic acid of summer (43.32 mg/100g), chlorophyll content (0.51 mg/100 g) as well as lowering titratable acidity of summer (3.66%). Wherein G4P1 i.e., (GA3 100 ppm double spray+15 cm shoot pruning) postponed harvesting to (207.80) days though non significantly. Nevertheless, fruit breadth and shelf life had a non significant increase over control. Thus, the experiment concluded that the treatment combination G1P1 i.e., (GA3 50 ppm single spray+15 cm shoot pruning) is most promising with results to meet the objectives of the experiment.en_US
