The research was carried out for a period of 3 weeks on the storability of tomatoes at three different stages of ripening (i.e. matured green stage, half ripe and fully ripe). They were sub divided into two equal sets each, one was kept at room temperature (between 28-300C) in the laboratory as the control while the second set stored in the ECS at a temperature between 19-230C. Parameters like percent rot, physical appearance and percent weight loss were assessed at 3 days interval, Tomatoes stored in the ECS had lower reduction in weight while remaining fresh but with higher percent rot. Tomatoes stored at room temperature recorded higher weight loss while recording lower percentage rot with a bad appearance. The matured green tomatoes were better during storage in both Harvesting of tomatoes at a matured green stage and storing in the ECS prolongs the shelf life of the tomatoes.
