Abstract:
The present investigation was undertaken with the view of determining the impact of humic acid and zinc sulphate on preharvest fruit drop and fruit growth of acid lime (Citrus aurantifolia Swingle). The experiment was carried out in a completely randomized design with three repetitions and seven treatments comprised of foliar application at pea stage of humic acid alone or with a combination of zinc sulphate. The foliar application of humic acid and zinc sulphate had a significant effect on preharvest fruit drop and fruit growth of acid lime. Among all the treatments, T₆ (Humic acid 40 ml/l + ZnSO₄ 0.5%) was the most effective, and it recorded significantly lowest fruit drop (16.16%), the maximum fruit volume (33.55 cc), fruit weight (34.20 g), fruit diameter (4.34 cm), number of fruits per plant (1641.33) and fruit yield (56.13 kg/plant).
