An experiment entitled “Effect pre harvest spray of different forms of calcium (CaCl2, Ca(NO3)2, CaSO4 each at 1 and 2%) on post-harvest quality of guava cv. Allahabad Safeda was conducted under randomized block design during the period of July, 2018 to January, 2019 at Fruit research station, Sangareddy, SKLTSHU, Telangana. The different levels of calcium had significant influence on the quality parameters. Various physical parameters like fruit length(cm), fruit diameter (cm), fruit weight (g), fruit firmness (kg/cm2), shelf life (days), PLW(%), spoilage(%) and bio-chemical parameters like TSS (æ Brix), ascorbic acid (mg/100g), titrable acidity (%), total sugars (%), reducing sugars (%), non- reducing sugars (%) and Brix: Acid ratio were recorded. Among different forms of pre-harvest sprays of calcium, Ca(NO3)2 @ 2% has recorded significantly the highest total soluble solids (11.39 æ B), ascorbic acid (159.49mg/100g), total sugars (9.00%), reducing sugars (5.23%), non-reducing sugars (3.78%), TSS: Acid ratio (31.08), fruit firmness (10.03kg/cm2), shelf life (8.51days) when compared to control. The same treatment recorded minimum acidity (0.37%), PLW (11.63%) and spoilage percentage (62.86%). Ca(NO3)2@ 2% emerged as best treatment to improve the quality attributes of guava cv. Allahabad Safeda.
