| dc.description | Radish (Raphanus sativus.L) belonging to the family Cruciferae is a popular
and widely grown vegetable in Bangladesh as well as in the different part of
the world. It has different uses as dish item like vegetable, green leaf, salad,
pickle and sauce. Rashid(1976) sited that a hundred gram of edible root
contain 1% protein,4% CHO,15 calories, negligible vitamins A, 0.3 mg
thiamin, 0.03 mg niacin, 25 mg vitamin C, 30 mg calcium and 1 gm iron. At
present China, India, USA and Turky are holding the position 1°, — 3" and
4" respectively for radish seed production. In Bangladesh radish is cultivated
in an area of 23.48 thousand hec. of land with a production of 85.42 thousand
metric ton. The average yield of radish is 1.47 mt/ha, which is very low in
Bangladesh (Anon. 2004). Radish is the third most important vegetable crop
next to potato and egg plant, fifth most important as vegetable seed crop next
to Onion, Amaranth, egg plant and Chilies in respect of total acreage (44000
ha) and first most important seed crop in respect of actual consumption (577
ton annually) for 140 million inhabitants of Bangladesh (Anon. 1997). Now a
day this crop is cultivated all the year round. At present 445 tons of radish
seed are produced in 44000 hectors of land in the country. Total requirements
of radish seed in Bangladesh are above 700 tons for vegetable purposes
(Anon. 1997). About the total requirement 48 % is locally produced by
government, NGO, s and some seed companies and rest 52% is imported
from abroad (Anon. 2005). The cultivation of radish as seed crop has
become very popular with some of the vegetable growers of the Dinajpur and
Rangpur region of Bangladesh. Seed production of radish is very specific in
its climatic requirements. The high yielding radish varieties popularly
cultivated in Bangladesh are of biennial type that does not produce good
seeds in our field conditions. A tropical annual type variety named Tasaki
was developed by the Bangladesh Agricultural Research Institute is capable of producing seeds abundantly under the local conditions. (Rashid ef al.
1985).Enough high quality healthy radish seed is not at all available in the
country. The average seed yield of the crop is below 0.5 t/ha whereas if the
modern technology is followed seed yield will be increased 2.5t/ha in our
country. Thus the seed yield of the crop in the country is relatively much
lower even though very favorable environment prevail every year, a huge
amount of radish seed is imported from outside of the country with
considerable amount of foreign currency. | en_US |
| dc.description.abstract | In total 45 seed samples of radish cv. Tasaki mula were randomly collected from
40 farmers of four upazillas (Birgonj, Kaharol, Badargonj and Taragonj)
comprising 10 farmers from each of the upazilla and five companies (Molla seed
company, Supreme seed company, Lal teer seed company, Metal seed company
and Alamgir seed company) were collected from Dinajpur local seed market
during the period of April to September 2007 for testing their quality and health
status. In field study, the field emergence of farmer’s seed samples ranged from
53.70-61.40% and company’s seed samples were found 50.50-73.00%. The plant
stand of farmer’s seed samples was found 37.20-44.40% and in company’s seed
samples were found 33.50-58.00%. In laboratory study, the germination
percentages were recorded 64.92-77.95% in farmer’s seed samples and 42.50-
85.00% in company’s seed samples. In case of apparently diseased seed 22.20-
64.00% were recorded in farmer’s seed samples and 22.07-39.75% in company’s
seed samples. The vigor indexes were recorded 917.32-1220.70 in farmer’s seed
samples and 531.68-1395.70 in company’s seed samples. The highest percentage
of Alternaria infected seed was observed 25.30% in Taragonj upazilla’s seed
sample and the lowest 22.40% in Birgonj upazilla’s seed samples, where the
highest 22.50% Alternaria infected seed was recorded in Molla seed company’s
seed sample and the lowest 17.25% was recorded in supreme seed company’s seed
sample. Finally it may be concluded that, company seed samples were superior in
quality than farmer’s seed samples regarding all parameters. | en_US |
