Popis: The investigation was carried out at the experimental orchard, Department of Fruit Science, Banda University of Agriculture and Technology, Banda during 2020-21. The experiment was planned in RBD having 10 treatments with 3 replications consisting of different combinations of plant growth regulators and micronutrient spray on acid lime cv. Ganganagar Lime – 1 to improve the yield of good quality fruits. Among the plant growth characteristics, the maximum increment in trunk girth (3.55 cm) were recorded with the treatment T8 - GA3 (75 ppm) + ZnSO4 (1%) + FeSO4 (1%) and maximum leaf area (24.56 cm2) were observed with the treatment T9 NAA (100 ppm) + ZnSO4 (1%) + FeSO4 (1%). Whereas the maximum yield (10.01 kg/plant) and minimum fruit drop (22.85 %) were observed with the treatment T10 - GA3 (75 ppm) + NAA (100 ppm) + ZnSO4 (1%) + FeSO4 (1%). The fruit quality characteristics like maximum average fruit weight (28.39 g), fruit length (41.26 mm), fruit width (40.51 mm), TSS (7.2 ºBrix), ascorbic acid (30.20 mg/100g) and juice percentage (52.73 %) were also recorded with the treatment T10 - GA3 (75 ppm) + NAA (100 ppm) + ZnSO4 (1%) + FeSO4 (1%). While, the maximum titratable acidity (6.81 %) were recorded with the treatment T9 - NAA (100 ppm) + ZnSO4 (1%) + FeSO4 (1%). The growth, yield and fruit quality of acid lime improved a lot as compared to untreated plants and the spray of GA3 (75 ppm) + NAA (100 ppm) + ZnSO4 (1%) + FeSO4 (1%) was recorded as the best treatment for the plants.
