Study on the effect of pre harvest sprays of calcium chloride and organic acids on yield and shelf life of grape (Vitis vinifera L.) cv. thompson seedless

A study titled effect of pre harvest sprays of calcium chloride and organic acids on yield and shelf life of grape (Vitis vinifera L.) cv. Thompson Seedless was conducted on 2023-2024 at Grape Research Station, Rajendranagar, Hyderabad. The research aimed to access the effect of calcium chloride and organic acids on yield and shelf life of grape (Vitis vinifera L.) cv. Thompson Seedless. The experiment followed a Randomized Block Design (RBD). Notably the study found that pre harvest sprays of fruits with calcium chloride T₂ - CaCl₂ @ 1.0% recorded highest berry length (19.55 mm), berry diameter (14.25 mm), number of berries per bunch (102.3), average berry weight (2.23 g), average bunch weight (205.80 g), number of bunches per vine (55.67) and yield (11.46 kg/vine) compared to other treatments. The results on physical parameters revealed that, among all the treatments T₂ - CaCl₂ @ 1.0% recorded lowest physiological loss in weight on 1st day (0.96%), 3rd day (3.59%), 5th day (9.04%), 7th day (15.92%), 9th day (27.92%) of storage and lowest decay (%) on 1st day (0%), 3rd day (2.18%), 5th day (6.47%), 7th day (14.93%), 9th day (29.33%) of storage. Among all the treatments T₂ - CaCl₂ @ 1.0% recorded highest shelf life (8.00 days). From this study it can be concluded that among all the treatments T₂ - CaCl₂ @ 1.0% recorded significantly highest berry and yield parameters, lowest physiological loss in weight and decay (%) and highest shelf life (days).
