Abstract:

The effect of pre-harvest spray of salicylic acid, calcium chloride and calcium nitrate on guava (Psidium guajava L.) cv. Allahabad Safeda studied to assess the impact on yield and quality of guava. Pre-harvest spray of calcium chloride 1.5 per cent and 1 per cent enhanced the fruit growth at 15 days after spray (DAS) and at harvest over control. Among the treatments, spraying of calcium chloride @ 1.5 per cent registered the maximum number of fruit per tree (103.33), fruit weight (162.47 g), fruit volume (164.47 ml), circumference (21.16 cm), firmness (1.83 kg/cm2), specific gravity (0.988 g/ml), yield (16.78 kg/ tree), titrable acidity (0.62 per cent), ascorbic acid (226.15 mg/g) and shelf life (10.33 days) over control (T7).
