Abstract

An experiment entitled entitled “Effect of pre harvest sprays of calcium compounds and bagging on post harvest quality of summer season guava (Psidium guajava L.) Cv. Allahabad Safeda” was carried at Jookal village in Jayashankar Bhupalpally district during the year 2022-2023. The experiment was carried out with Factorial Randomized Block Design (FRBD) with 15 treatments and three replications with 2 factors. Factor one consists of sprays viz., S1- CaCl2 @ 1 %, S2- Ca(NO3)2 @ 1 %, S3- CaSO4 @ 1 % and factor two consists of bagging materials viz., B1- Muslin cloth bag, B2- Non woven bag, B3- Brown paper bag, B4- Blue polyethylene bag, B5- No bagging (Control).The experiment results revealed that pre harvest sprays of calcium compound Ca(NO3)2 @ 1 % and bagging with muslin cloth bag resulted in maximum fruit quality parameters such as TSS (13.33 °Brix), total sugars (15.55 %), reducing sugars (5.72 %), non reducing sugars (9.83 %), ascorbic acid content (196.99 mg /100g of pulp), pectin content (1.28 %) and minimum titratable acidity (0.28 %).These findings highlight the importance of different spraying of calcium compounds and bagging materials on fruits that controls fruit flies,pests ,diseases and improves the post harvest quality of fruits.

Conclusion

Among the pre harvest sprays of calcium compounds, significantly maximum TSS, total sugars, reducing sugars, non reducing sugars, ascorbic acid content, pectin content and minimum titratable acidity was recorded in S2- Ca(NO3)2 @ 1 %. Among bagging materials, significantly maximum TSS, total sugars, reducing sugars, non reducing sugars, ascorbic acid content, pectin content and minimum titratable acidity was recorded in B1- Muslin cloth bag. In interaction effect of pre harvest sprays of calcium compounds and bagging, significantly maximum TSS, total sugars, reducing sugars, non reducing sugars, ascorbic acid content, pectin content and minimum titratable acidity was recorded in S2B1 - Ca(NO3)2 @ 1 % + Muslin cloth bag . It is concluded that pre harvest sprays of calcium compounds and bagging on quality parameters viz., total soluble solids, total sugars, reducing sugars, non reducing sugars, ascorbic acid content, titratable acidity and pectin content was observed best with the treatment Ca(NO3)2 @ 1 % + Muslin cloth bag. The experiment concluded that different sprayings of calcium compounds and bagging materials improve the post harvest quality of fruits.
