Abstract
An experiment was conducted to assess the seed and seedling quality of onion stored in metal container (Tin), polythene bag and cloth bag at room temperature. Seed quality assessment included seed moisture content, germination percentage, thousand seed weight and seedling quality regarding pathogen percentage, knee and root length per seedling and total dry weight per seedling. Among the three containers, moisture content of the seeds of tin pot and polythene bag were increased significantly to 10.33 and 9.97 %, respectively from initial moisture content of 9.40 %. Seed moisture content of cloth bag also increased from initial moisture content of 9.40 to 11.8 0%. Germination percentage decreased gradually from 85 to 67 % in the seeds of cloth bag. But slow decrease of germination from 84 to 76 % was observed in the seeds of tin pot and 84 to 82 % of polythene bag seeds. The lowest thousand seed weight (3.16g) was recorded in metal tin pot at 15 days after observation and the highest (3.35 g) in cloth bag at 60 days after observation. The highest knee length (6.67 cm) was recorded in metal container (tin) at 15 days after observation and the lowest (4.30 cm) in cloth bag at 60 days after observation. The highest root length (29.40 mm) was recorded in polythene bag at 30 days after observation and the lowest (20.70 mm) in cloth bag at 15 days after observation. The highest percentage of pathogen (6%) infected seed was recorded in cloth bag at 60 days after observation and the lowest (2.0%) infected seed in metal container (tin) and polythene bag at 30 days after observation. The highest value for total dry weight (0.057 mg) was recorded in metal container (tin) at 45 days after observation and the lowest value (0.033 mg) in cloth bag at 15 days after observation. From the results it may be concluded that metal tin container is the most effective one for long period of storage than polythene and cloth bag storage.
