Abstract:
The present investigation was undertaken with the view of determining the "effect of humic acid and zinc sulphate on quality and post-harvest life 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. Results obtained, among all the treatments, T6 (Humic acid 40 ml/l + ZnSO4 0.5%) was the most effective and it recorded significantly the maximum shelf life (16.14 days) the lowest physiological in weight (8.36%) spoilage % (3.55%) and average seed content (8.97). The foliar application of humic acid and zinc sulphate significantly affected quality parameters, viz., TSS (oBrix), ascorbic acid (mg/100 ml of juice) and juice content (%). Among all the treatments, the T6 treatment was the most effective and recorded significantly the maximum TSS (8.27 oBrix), ascorbic acid (37.70 mg/100 ml) and juice content (46.73%), while treatment T1 (Control) recorded significantly the maximum acidity (8.21%). Similarly, 10 days after harvest, the same treatment T6 had the highest TSS (8.50 oBrix), ascorbic acid (34.37 mg/100 ml), and juice content (46.73%), while treatment T1 (control) had the highest acidity retention (8.14%).
