How Does Storing Containers on Farmers Stored Boro Rice Seed Affect the Seed Qualities?

摘要

The experiment was conducted at Laboratory of Plant Pathology, Bangladesh Agricultural University (BAU), Mymensingh and Seed Pathology Centre, BAU, Mymensingh during 2010 to 2014 to investigate the effect of storing containers on moisture content, germination percentage, seedling vigor, apparently healthy of seeds and infection of rice stored seeds. The rice seed samples of cv. BR14, BRRI dhan28, BRRI dhan29 and Guti were collected from 36 farmers belonging to the individual villages at Ishwarganj Upazila under Mymensingh District. Four types of storing containers were used by farmers own selves following traditional practices. Storing containers were gunny bag lined with polythene, bamboo bin lined with polythene, gunny bag and earthen pot locally called motka. The highest percentage of moisture content was in gunny bag (14.32%) and the lowest in gunny bag lined with polythene(12.59%) similarly best germination was in gunny bag lined with polythene (78.04%) and worst in motka (65.16%) consequently maximum vigor index was shown in gunny bag lined with polythene (1756) and minimum in motka (1458). The experiment also found the highest percentage of apparently healthy seeds in gunny bag lined polythene (55.01%) and lowest in motka (46.42%).Sequentially maximum seed borne fungi infection occurred in gunny bag (28.98%) and minimum infection in bamboo bin lined with polythene (22.70%). The result of the experiment evidently proved that polythene sheet was the key indication to protect the quality of seeds. On the other hand, the earthen pot or motka was the worst material to deteriorate the quality of seeds during storing time.
