Abstract:
Background and Objective: The high post-harvest losses of grain ranging between 35 and 46% are attributed to the adverse weather conditions that favour growth of a number of insect pest and mites harmful to stored products, which reducing the quantity and/or quality of the stored products. Thus, this study aimed to evaluate the effect of packages types and grain treatments on storage efficacy and germination and seedlings parameters of rice during different storage periods (3, 6, 9 and 12 months after harvesting). Materials and Methods: A laboratory experiment was conducted at Agronomy Department Laboratory of Seed Testing, Faculty of Agriculture, Mansoura University, Egypt. The experiment was arranged in a factorial experiment in randomized complete block design with four replications. Results: Increasing storage periods of rice grain from 3, 6, 9 and 12 months after harvesting significantly affected storage efficacy character (insect infestation percentage), germination parameters (final germination, abnormal seedlings, sold and rotten grains percentages) and seedling parameters (root and shoot lengths, seedlings dry weight and seedling vigor index). The best results of storage efficacy, germination and seedlings parameters of rice recorded when sealed stored in metal packages, followed sealed stored in polyethylene, then unsealed stored in light cloth and lastly unsealed stored in paper packages. The lowest percentage of insect infestation and maximum values of germination and seedling parameters were obtained from fumigation rice grains before storage with phosphine at the rate of 5 tablets/m3. Conclusion: This study concluded that fumigation rice grains before storage in metal packages with phosphine.
