This investigation aimed to study the effect of foliar applications of Silicon, Boron and Calcium- ETDA alone or combinations at different berry development stages to determine their effects on growth parameters, shelf life, yield and quality in table grapes under tropical conditions of India. The experiment was carried out at The experimental trial was carried out onClone 2A Seedless grapes grafted on Dogridge rootstock in the Maharashtra Rajya Draksh Bagaitdar Sangh, vineyard for the year (2016-2017). Pune (18.32 °N and 73.51°E) has tropical wet and dry climate with an average temperature ranging between 20 to 28 °C.The result obtained proved that all parameters such as vegetative growth, total chlorophyll content, leaf area m2,bunch weight, berries weight, berry diameters, berry size, TSS acidity were improved while compared with untreated control. The Si, Ca- EDTA and B treated vines recorded minimum fresh weight loss % and longer shelf life compared with alone and untreated control. The Si, Ca – EDTA + B treated leaves rachis and petiole had the highest Si, Ca- EDTA and B content uptake. Therefore, Si, Ca-EDTA + B foliar sprays increased and retained yield, quality, berry firmness, visual quality, and nutrient content, prolonged shelf life was noted in the study.
