Abstract
Seed perform a vital role in agricultural sector for crop production as well as seed business. Scarcity of healthy seed hinder not only the crop production but also the quality of seed. Storing of healthy seed with proper storing condition is one of the suitable methods to maximize production however, healthy seed also lose its quality during seed storage. Seed remains viable for long time if the seed stored by maintaining seed moisture content, storage temperature with storage container. So, this experiment was carried out to observe the quality parameters of jute seed during long term storing. To find out the storage effect an experiment was conducted on march, 2020 at seed laboratory, Jute Agriculture Experimental Station, Jagir, Manikganj, Bangladesh during the period of January 2016 to March, 2020. Plastic pot was used in this experiment as a storage container to store jute seeds. Three tossa jute (C. olitorius L.) varieties viz., O-795 (V1), O-9897 (V2) and OM-1 (V3) were used in this study. Result revealed that storage period and jute variety showed significant effect on different seed quality parameters. The highest seed germination, field emergence, seed vigour and the lowest 1000-seed weight, moisture content were recorded in T5 (2019-20) treatment. On the other hand, the lowest seed germination, field emergence, seed vigour and the highest 1000-seed weight, moisture content were recorded in T1 (2015-2016) treatment. Furthermore, seed germination, field emergence, seed vigour was negatively but 1000-seed weight was positively correlate with moisture content. Results revealed that extended storage period caused the decreasing seed quality and seed can be stored for three years in plastic container without hampering the seed quality.
Highlights
Seed quality can be deteriorated in various ways and storage period is one of them (Anderson, 1970; Wang et al, 2018)
The effect of storage periods was evaluated on tossa variety (Corchorus olitorius) seed quality
Percentage of seed germination and field emergence as well as seed vigour was higher in T4 and T5 treatments and lower in T1 treatment
Summary
Jute grows abundantly in Bangladesh having best quality of fiber in comparison with that of India (Zakaria and Sayed, 2008). Jute and jute products earn a lot of foreign currency and jute alone contributes about 5.5% to the GDP in Bangladesh national economy (Sikder et al, 2008). For the foreign earning, jute is called golden fiber of Bangladesh. In 2016 2017, about 8.39 million tons of jute fibre were produced from 10.89 million acre of land and covered about 2.80% of the total cropped area (BBS, 2018). It has been reported that jute covers almost 6.0 billion of taka as export materials in the fiscal year 2018-2019 (Akter et al, 2020). Jute crop significantly improves the soil fertility and soil quality by adding organic matter to the soil through the decomposition of dropped leaves and plant debris (Islam and Ali, 2017). Jute and jute goods have been recognized as being ecofriendly to the environment globally (Abdullah, 2002)
