ABSTRACT

Three vegetables and 3 varieties of each vegetable viz. seeds of Country bean (IPSA-1, BARI-4 and Noldog);
Brinjal (Debgiri, Uttara and Singhnath); and Tomato (Raton, Ruma VF and Jalali) were taken under testing to
know the seed emergence efficiencies of available vegetable seeds in Mymensingh Sadar upazila of
Bangladesh. To carry out the study during the period from September, 2016 to November, 2016 experimental
vegetable seeds were collected from four different seed companies such as Ispahani Agro limited, Lal Teer
Seed Company limited, Krishan Agro Service and Supreme Seed Company limited. The seed emergence

efficiencies were determined in the laboratory of the Department of Seed Science and Technology and Eco-
friendly Plant Disease Management Laboratory; Bangladesh Agricultural University (BAU), Mymensingh in

respect of moisture content, 1000-seed weight and seed germination percentage. The moisture content varied
significantly from one to another, while minimum (8.34%) and maximum (12.60%) records were made in
Jalali (tomato) and IPSA-1(country bean), respectively. In respect of 1000-seed weight, minimum 1000-seed
weight (0.70g) was found in variety Ruma VF (tomato), but maximum 1000-seed weight (1130g) was
recorded in BARI-4 (country bean). In case of germination of vegetables seeds of normal seedlings of
different seed companies ranged from 50.00 to 66.00%. The highest percentage of normal seedlings was
found 66.00% in variety Ruma VF (tomato) collected from Krishan Agro Service and the lowest 50.00% in
variety BARI-4 (country bean) collected from Ispahani Agro limited.
Key words: Vegetable seeds, seed moisture, seed germination, variety.
Introduction
Bangladesh is predominantly an agriculture based country with more than 149 million peoples living on
14.84 million hectares of land. Population is expected to increase to 200 million by 2050. Agriculture is
still the largest employment sector and it accounts for 32% of its gross domestic product (GDP) and
absorbs 63% of the country’s labor force (Winberger and Genova, 2006). The performance of this sector
affects the overall economic growth. Crops share about 23% of total GDP. The net cropped area is about 14
million hectares and the cropping intensity is more than 180%. ‘Vegetables’ constitute a potential and
important group of crops in Bangladesh. Vegetables are important for their low cost of production, short
duration of production and high nutritive value. In 2013-2014 about 926 (‘000’) acres of land were under
vegetable cultivation in Bangladesh and production was 3365 (‘000’) tons (BBS, 2014). But it is the matter
of concern that about 200 different seed-borne pathogens including more than 100 fungi have been reported
to cause diseases in different vegetable crops in the world (Richardson, 1990). Sultana (2009) estimated
eight seed borne fungi associated with the seeds of Bottle gourd, Sweet gourd, Snake gourd, Ridge gourd,
Cucumber, Wax gourd and Sponge gourd collected from BADC and other seed company. She found that

only Aspergillus spp. was highly prevalent in all the crop seeds ranging from 1.6-14%. A total of 18 seed-
borne fungal pathogens have been reported from the seeds of four selected crops, of these; 10, 4, 2 and 2

fungal pathogens have been found associated with the seeds of Spinach, Bottle gourd, Indian spinach and
Red amaranth, respectively at home and abroad (Fakir et al., 1991 and Islam, 2005). It is unquestionable
that proper disease control measures should be taken for the production of quality seeds. Healthy or
pathogen free seeds are considered as the vital factor for desired plant population and good harvest. Seeds
of vegetables are more vulnerable to attack by pathogens and quickly deteriorate in storage. Seed health, an
essential component of seed quality is important for seed germination; seedling vigour and plant stand in
