Identification of Appropriate Maturation Stages and Postharvest Treatment for Tomato Fruits of the "Pearson" Variety for Local and Distant Markets

This study was conducted under ambient conditions at the research farm of the Agriculture Faculty at Kabul University, Afghanistan. The objectives were to identify suitable harvesting maturity stages for tomato crop that will result in adequate shelf life of tomato fruits for local and distant markets. The results indicated that fruits of the turning color stage treated with 6 % CaCl2 solution had the best quality and highest shelf life (17.5 days) compared to other treatments. Based on the significant main effect, the 15.38 and 14.17 days’ highest shelf life was recorded for tomatoes of H1 (turning color stage) and D1 (dipped in 6 % CaCl2 solution), respectively. The TSS ( o Brix) and PLW (%) were increased till the end of storage life, but the tomato fruits’ firmness (g cm-2) decreased. Hence, the lowest values were noted as 4.79 and 4.74 (0 brix) TSS and 3.31 and 2.93 (%) PLW, but the highest firmness of 932.50 and 854.17 (g cm-2) were recorded for fruits of H1 (turning color stage) and D1 (dipped in 6 % CaCl2 solution), respectively. The turning color, pink color and light red color stage fruits of the Pearson variety are recommended to be harvested and considered for distant market, local market and immediate use, respectively. And the 6 % CaCl2 solution could increase shelf life and maintain tomato’s quality.
