“…The Ca-pectate concentration was positively correlated with the titratable acidity (TA) (Table 3). Some authors have reported an increase in TA with Ca application which can influence the Ca concentration in fruit (El-Masri et al, 2021;Santhosh et al, 2021;Khakpour et al, 2022). El-Masri et al ( 2021) observed an increase in TA in table grapes berries after Ca application with different sources of fertilizers.…”

The cultivation of fruit trees is influenced by abiotic factors such as nutritional management. However, fertilizers are used in large amounts in vineyards, resulting in excess nutrients that can cause stress and reduce fruit quality. Calcium (Ca) is one of the most used nutrients in vineyards due to its effects on fruit quality. However, excess of Ca interferes with the distribution of Ca compounds in fruits, being a form of abiotic stress. The aim of this study was to evaluate the influence of the nutritional balance of table grape orchards on calcium nutrition and fruit quality. Nineteen table grape orchards were selected in the Submédio São Francisco Valley in 2019 and 2020 crops. The nutritional diagnosis was performed using the integrated diagnosis and recommendation system (DRIS) and the average nutritional balance index (NBIm) was calculated. The concentration of Ca-pectate, Ca-total, berry firmness, soluble solids, titratable acidity, soluble solids/titratable acidity ratio and dry matter were determined in the fruits. The nutritional diagnosis identified excess Ca in the orchards. The correlation between Ca-pectate and the average NBIm was negative, indicating that the Ca-pectate concentration is higher in vines that are more nutritionally unbalanced. However, the Ca-total in the fruit was not correlated with Ca-pectate. Ca-total and Ca-pectate were not correlated with berry firmness. Calcium nutrition is complex and highlights the importance of associating the assessment of nutritional balance with Ca in fruit quality to optimize the nutritional management of the grapevine.

“…Additionally, the study did not look at the storage characteristics of the fruit or the impact of the Ca application on the firmness after storage, so the current results offer new information over this previous study as they show that the application of Ca+ai increased fruit firmness for up to 9 WAH. Another study looked at different calcium sources (calcium sulfate, calcium nitrate, calcium silicate, poultry manure and pressmud), which were all applied at rates up to 80 kg ha −1 calcium [16], which can be compared to the rate of 0.91 kg ha −1 used in this study. Their findings showed that the highest fruit firmness over 15 d monitoring postharvest was obtained from the 80 kg ha −1 calcium as poultry manure.…”

“…Other work assessed the source of calcium with calcium sulfate, calcium nitrate, calcium silicate, poultry manure and pressmud (sugarcane processing waste product) being used at application rates up to 80 kg ha −1 calcium. Poultry manure resulted in the greatest fruit firmness after harvest with the calcium sulfate, calcium nitrate and calcium silicate all resulting in similar firmness levels [16].…”

Tomato (Solanum lycopersicum L.) had almost 190 million tonnes produced in 2021. Tomato fruit suffer losses of up to 50% during harvest and transport, which causes financial hardship, reduces the amount of food available and causes environmental harm. Calcium plays an important role in cell wall strength. This work assessed the use of a calcium transport stimulant (MCAS) to increase the firmness of tomato fruit in the laboratory and the foliar application to tomato plants. Then, handling damage was simulated. In the laboratory, the calcium with MCAS significantly increased the fruit firmness compared to the untreated and calcium without MCAS, which were not significantly different. When calcium with MCAS was applied to tomato plants foliarly before harvest, the calcium with MCAS-treated fruit were significantly firmer than the untreated or calcium without MCAS-treated fruit for up to 10 weeks after harvest, and this was achieved by applying only 0.91 kg ha−1 calcium. Finally, when fruit were exposed to a simulated drop, the calcium with MCAS-treated fruit remained firmer than the undamaged fruit or dropped fruit with calcium without MCAS. Calcium with MCAS could significantly increase the fruit firmness and increase the shelf-life of tomatoes while applying less calcium.
