Influence of preharvest fruit bagging on yield and economics of grape cv. crimson seedless

Abstract

This investigation entitled “Influence of Preharvest Fruit Bagging on Yield and Economics of Grape cv. Crimson Seedless” was carried out during 2024-2025 at Sector No. 70, Grape Orchard, Main Horticultural Research and Extension Centre, University of Horticultural Sciences, Bagalkot. The experiment consisted of twelve treatments, each replicated three times, involving different types of fruit bags to assess their influence on yield and quality attributes of grapes. The trial was laid out in a randomized completely block design (RCBD). Bagging was imposed when the berries attained a size of approximately 6-7 mm, and all bags were removed one week prior to harvest. Among the various treatments, the use of white non-woven polypropylene bags was found to be the most effective, recording the highest bunch volume, bunch weight, berry diameter, berry weight and berry length, along with maximum net returns. Overall, fruit bagging significantly improved yield and economic gains of Crimson Seedless grapes compared to the unbagged control.
