A Study on the Rice Storage Systems and Loss Estimates in the BRRI Regional Station, BARIsal

Abstract/ Executive Summary:

The investigation was started at the moisture contest of 12, 12.5 and 10.9 percent for BR3, BR14 and BR16 variety respectively. The germination percentage of those varieties were 39, 88 and 89 respectively. However, the results showed that viability of seed was reduced from 89 to 82% of BR3 in gunny bag, 88 to 14% of BR14 in drum and 89 to 79% BR16 in drum. The viability of BR 14 was drastically decreased due to high initial moisture content and high grain mass relative humidity. The insect infestation followed the traditional normal curve.

Keywords: Seed viability, Storage Structure, Gunny bag, Drum, Insect infestation, Moisture content

Location: Barisal

Start Date: 01-07-1989

End Date: 30-06-1990

Program Area: Farm Mechanization

Commodity: Farm machineries

Objectives:

To define and describe the existing storage practices and procedures operating at the station
To determine the storage losses
To identify the storage problems
To recommend possible solutions

Methodology:

The post harvest operations and the storage systems of Barisal regional station was investigated. It has a concrete threshing floor and a small shed for post harvest operations. The store building consists of three rooms of which one is used for storage of research seeds, the next room is used for storage of other seeds and mixed paddy. The third room is used for fertilizers and implements.Usually threshing is done by the pedal thresher or beating followed by animal treading. Winnowing is done by hand operated winnower or by manually operated ‘kula’. The cleaned paddy dried on the concrete floor and is stored in gunny bags or small metal drums inside the storage building. Seed viability, moisture content and insect infestation were recorded for different storage structure.

Achievement/Findings:

i) The storage system of this regional station was not proper and scientific. ii) Proper ventilation system should be provided. iii) regular cleaning of store is needed for better storage management. iv) Proper storage bins, drums, dole, etc should be introduced for seed storage.
