Effect of foliar application of plant growth regulators and micronutrients on growth and yield of acid lime cv. kagzi (Citrus aurantifolia swingle)

Treatmentwith ZnSO₄ 0.5% + FeSO₄ 0.5% produced significantly maximum height of the tree (3.45, 3.73 and 3.98 m at 4, 6 and 8 month after first spray), East West canopy spread (3.44, 3.76 and 4.04 m at 4, 6 and 8 month after first spray), South North canopy spread (3.40, 3.70 and 3.97 m at 4, 6 and 8 month after first spray). Yield attributing characters like fruit volume (47.90 cc), fruit diameter (4.54 cm), fruit weight (47.40 g) and fruit yield per tree (46.38 kg) significantly increased under the treatment of GA₃ 50 mg/l. In case of number of fruits per tree, treatment with NAA200 mg/l significantly increased the number of fruits per tree (1020.33).
