“…There was no significant difference for fruit pH as a function of foliar application of calcium sources (Tables 1, 2, and 3). Similar behavior was verified for tomatoes of the Santa Cruz group that received foliar application of a calcium silicatebased fertilizer during their production phase (Coutinho et al, 2020). The pH of the pH of the fruit had increased with storage time, regardless of whether the plants were sprayed with foliar fertilizers (Tables 1, 2, and 3).…”

The objective of this study was to evaluate the post-harvest quality of Sweet Grape tomatoes, with and without nutritional deficiency, subjected to sources and frequency of application of foliar fertilizers based on Ca. Two experiments were conducted with storage of the fruit in different climate chambers: 25 and 11 ºC. The experiments were conducted in a randomized block design with subdivided plots. The Ca sources used via foliar fertilization were allocated to the plots: calcium chloride and calcium acetate at a concentration of 0.3% Ca, and deionized water. In the sub-plots the frequencies of foliar fertilizer application (7 or 14 days) were allocated. The sub-sub-plots received the periods of fruit evaluation during storage (0, 9, 18, and 27 days).In each experiment and evaluation period, firmness, pH, soluble solids content, and titratable acidity of the fruit were determined. In both plants that received adequate and low Ca supply in the nutrient solution. Foliar fertilizer applications increased initial fruit firmness, regardless of the frequency of application, enabling longer storage time at both temperatures. There were no differences between the treatments in the evaluations referring to the taste of the fruits during the storage periods.

“…Ripening significantly degrades the cell wall components by means of enzymatic activity such as polygalacturonase and pectin methylesterase, which leads to softening of fruit tissue [29,30]. However, calcium in fruits tissues has an inhibitory effect on the activity of polygalacturonase, which retards the ripening process [31,32].…”

Postharvest quality maintenance of tomatoes is very crucial because of its perishable nature. Calcium, directly involved in the physiological process and enzymatic activities, thereby helps in maintaining the postharvest quality. Increasing calcium concentration reduces respiration and ethylene production in succession; it increases the shelf life and quality of tomatoes. Hence, a field experiment was conducted with different sources and levels of Ca, namely, calcium sulfate, calcium nitrate, calcium silicate, poultry manure, and press mud applied at 0, 20, 40, 60, and 80 kg Ca ha −1 . Ripened tomatoes were harvested from each plot. Eight fruits were selected randomly from every treatment and divided into destructive and nondestructive samples, arranged in a factorial completely randomized block design for conducting a storage study. Shelf life, ascorbic acid, lycopene, beta-carotene, and polygalacturonase were analyzed at a 5-day interval up to 15 days. The results revealed that the effect of calcium sources had significant (p ≤ 0.05) impacts on fruit quality. The tomatoes harvested from poultry manure retained the highest shelf life (15 days) at 80 kg Ca ha −1 and the highest ascorbic acid content (37.5 mg 100 g −1 ) at 60 kg Ca ha −1 . However, the lowest lycopene (2.86 mg 100 g −1 ), beta-carotene (1.81 mg 100 g −1 ), and lesser polygalacturonase activity (1.99 kj m −2 ) were obtained with poultry manure at 80 kg Ca ha −1 . From the results procured in this experiment, it was inferred that the application of poultry manure at 80 kg Ca ha −1 was found to be effective in improving the quality attributes of hybrid tomato as it imparts multiple essential nutrients along with calcium.
