Abstract/ Executive Summary:

Storage of rice is crucial postharvest operation. Traditional rice storage structures vary over local resources, climate and culture in Bangladesh. This study was carried out to investigate the efficacy of diversified rice storage structures at farmer’s level. Household survey was conducted through face to face interview of farmers using developed pretested questionnaire. Rice samples were also collected to test the quality of stored rice. Six different types of traditional structures namely Dole, Steel drum, Plastic bag, Plastic drum, Gunny bag and Motka for rice storage were identified. Maximum insect infestation in stored rice was observed in Dole followed by Motka, Plastic Bag and Plastic drum. This may be due to upper surface of Dole was open. Germination capacity went down to 68% in Plastic bag, 55% in Motka, and 80% in Plastic drum. Rice storage in Plastic drum was found effective in terms of insect infestation and germination capacity in comparison with other traditional storage structures Motka, Dole and Plastic bag. Therefore, Plastic drum can be an alternative option in rice storage.

Program Area: Postharvest and Agro-processing

Commodity: Rice

Objectives:

To identify existing storage technologies at farm level and determine efficacy of those for rice storage.

Methodology:

Location: The experiment was carried out to identify the existing paddy storage structures and determine the efficacy of those collecting stored rice samples from the selected site of Phulpur, Mymensingh district. Phulpur is located at 24.9500°N, 90.3500°E of Mymensingh district. Household selection: Twenty five household was surveyed to identify traditional storage structures used by farmers through pretested questionnaire. Ten farmers were selected to evaluate rice stored in traditional storage technologies at farmer’s houses at each villages of Phulpur upazilla in Mymensingh district, Bangladesh. Four village of this site was Nagua West, Nagua East, Chalk Nagua and Fatepur at Phulpur, Mymensingh. Insect infestation: Rice sample of 250 g was collected from the top layer of farmer’s storage technologies (10- 15 cm) by a sampler and kept in polythene bag with an identification card and tied with a thread. The samples were separately selected from farm households from each area for the study. For easy identification and counting, samples were kept in deep freeze (2-4⁰C) for few minutes to make insect immobile. Then total number of insect was counted for each sample. Different prevailing insects were identified based on their respective identifying character. Germination test: Germination (%) of stored rice was determined on sand media in plastic box following the International Seed Testing Rules (ISTA, 1999). Germination capacity was calculated by the following formula: Germination % = Number of normal seedlings/400 × 100.

Achievement/Findings:

In Bangladesh, a fraction of population suffers food insecurity due to poverty, natural hazard, manmade calamity and unemployment of a group of people. A safe storage system of rice is important for ensuring food security especially for the people who are fully dependent on agriculture. Rice is generally stored by the farmers to meet their own consumptions throughout the year and seed for next sowing season. Six types of traditional rice storage structures were identified used by the farmers at Mymensingh District. Highest insect infestation of stored rice was found in Dole whereas the least amount of insect infestation was observed in Plastic drum after five months of storage followed by plastic bag. It might be due to persistence of high moisture content and high level of oxygen. Due to open upper surface and porous behavior of Dole, favors of growth insects more than that in other structures. After five months of storage average germination capacity was fall down to 73%, 55% in Dole and Plastic bag, respectively but it was within seed standard (80%) in Plastic drum. Among the different storage structures, Plastic drum is the best storage structure for rice storage. Therefore, Plastic drum can be an alternative option in rice storage.
