Enhancing the quality of stored rice seeds and grains using hermetic storage grain bag in Assam, India

Post-harvest losses (PHL) are a major concern, particularly in rice, with estimates ranging from 10 to 30% throughout its value chain. Effective seed storage is crucial for minimizing these losses, which are primarily caused by inadequate drying, adverse storage conditions, and pest infestations. Hermetic storage has emerged as a significant alternative to traditional storage methods. This study aimed to compare the effectiveness of two storage methods—gunny bags and super grain bags over six storage periods (from initial to five months) at two locations (Dikhowmukh in district Sivasagar and Khanamukh in district Jorhat) in Assam, India. The experiment was laid with a completely randomized design. Moisture content, germination percentage, and live and dead insect counts were recorded after the completion of each successive month for a period of five months. The observations were recorded considering the ambient temperature, external humidity, and temperature. Results indicated that storage methods significantly influenced all parameters, while storage duration influenced only insect counts. Super grain bags maintained lower moisture levels, improved germination rates by 11.2%, and reduced insect infestation and broken grain percentages compared to gunny bags. The findings suggest that super grain bags are a superior option for paddy seed storage, effectively reducing PHL and enhancing seed quality.
