Abstract:
To determine the impact of foliar spraying plant growth regulators and micronutrients on the physio-chemical analysis of acid lime (Citrus aurantifolia Swingle) cv. Ganganagar Lime-1, the investigation was conducted in 2020–2021 at the experimental orchard, Department of Fruit Science, Banda University of Agriculture and Technology, Banda. The experiment was set up in RBD (Randomize Block Design) having 10 treatments with 3 replications which were treated with different concentrations of growth regulators and micronutrients. Among the plant growth attributes, the maximum initial fruit set (75.04%) and final fruit set (53.66%) were observed with the treatment T₁₀ - GA₃ (75 ppm) + NAA (100 ppm) + ZnSO₄ (1%) + FeSO₄ (1%). Whereas the maximum number of seeds / fruit (6.10) were recorded similar with the treatment T₄ - (GA₃ 75 PPM + ZnSO₄ 1%) and T₁₀ - GA₃ (75 ppm) + NAA (100 ppm) + ZnSO₄ (1%) + FeSO₄ (1%) and the highest Rind thickness (mm) (1.98) reported with the treatment T₂ - GA₃ (75 ppm) + NAA (100 ppm). The other fruit quality attributes like maximum total sugars (1.66%) and reducing sugars (0.88%) were also recorded with the treatment T₁₀ - GA₃ (75 ppm) + NAA (100 ppm) + ZnSO₄ (1%) + FeSO₄ (1%). The spray of GA₃ (75 ppm) + NAA (100 ppm) + ZnSO₄ (1%) + FeSO₄ (1%) can be advised to farmers and researchers to achieve maximum fruit yield and good fruit quality in Ganganagar Lime-1 cultivar of acid lime based on the results of foliar spray of plant growth regulators and micronutrients on growth, fruit yield, and quality of acid lime under Bundelkhand region of Uttar Pradesh.
