Abstract

Sapota is grown in a variety of tropical and subtropical climates around the world. It is delicious, nutritive and it is primarily cultivated for fresh consumption. Sapota has a very short postharvest life due to its highly perishable nature. Proper pre- and postharvest treatments are essential to extend the shelf life and improve the quality of sapota. Hence the present investigation was conducted “To develop a process for uniform ripening and enhancing the shelf-life and quality of Sapota” at the Horticultural College and Research Institute (HC & RI), TNAU, Coimbatore to find out the influence of pre and post harvest chemical treatments on physical characteristics of sapota fruit (var. PKM-1). The experiment was laid out in Factorial Randomized Block Design with three replications. Among seven different pre harvest treatments, the treatment which comprised of 2% Potassium sulphate has recorded the highest fruit length (9.9 cm), fruit girth (15.2 cm), pulp weight (115.40 g), fruit

Potassium sulphate; Ethephon; Pre-harvest spray, growth regulator, sapota, physical and quality characters of sapota.

Conclusion

On the basis of present studies the pre-harvest treatment with 2% potassium sulphate combined with post harvest treatment of ethephon solution @ 1500 ppm +25 μ LDPE bag with O2 @ 5% & CO2 @ 10% at 11oC (T4P1S1) has increased the fruit firmness (3.9 kg/cm2), TSS (21.8°Brix) and shelf life (13 days) and decreased physiological loss in weight (1%) and acidity (0.1%). Sapota is one of the important fruit crops in India. Places like Gujarat, Maharashtra, Karnataka and Tamil Nadu share the maximum part in terms of production. Therefore, proper management practices before and after the harvest of the crops should be suggested to the farmers which helps to increase in shelf life and quality of sapota fruits.
