The experiment pertaining to the present investigation was carried out in the laboratory of the Department of
Seed Science and Technology, Bangladesh Agricultural University (BAU), Mymensingh. The experiment
was conducted during the period from September, 2016 to November, 2016. Three vegetables and 3 varieties
of each vegetable viz. Country bean (IPSA-1, BARI-4 and Noldog); Brinjal (Debgiri, Uttara and Singhnath)
and Tomato (Raton, Ruma VF and Jalali) were selected for conducting the experiment. Seed samples were
collected from different seed companies’ viz. Ispahani Agro limited, Krishan Agro Service, Lal Teer Seed
Company limited and Supreme Seed Company limited. Collected seed samples were categorized by dry
inspection as apparently healthy seed 55 to 69%. It had been recorded that the collected seed samples
contained discoloured seed (10 to 18%), shriveled seed (10 to 22%), other seed (0.00 to 4%) and inert matter
(1.0 to 7.0%). The highest number of apparently healthy seed (69%) was recorded from variety Ruma VF
(tomato) of Krishan Agro Service and the lowest (55%) from Noldog (country bean) collected from Supreme
Seed Company limited. The highest percentage of pure seed was found in Noldog (country bean) 97%
collected from Supreme Seed Company limited and the lowest in Ruma VF and Jalali (tomato) 91% collected
from Krishan Agro Service.
Key words: Vegetable seeds, Seed Company, healthy seed, seed purity.
In recent time Food Security, Poverty alleviation and Sustainable Agriculture became talk of the society,
talk of the people and talk of the seminars. These topics are now addressed by Global leaders, Economists,
Social reformers, Politicians and Civil Society. All these topics are aiming to one point that is-“Production
of more food”. To get more produce, good seed is the must and cannot be compromised under any
circumstances (Anam, 2009). Among the Agricultural inputs, seed is the most vital input that play key role
in increasing the yield of the crop. 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. Health of seeds can be affected by direct infection of pathogens or
through contamination of seeds by pathogenic propagules as contamination in, on or with the seeds or as
concomitant contamination (Rahman et al., 2002). Infection of seed by pathogenic organism and presence
of propagules of pathogen in a seed lot is vitally important because infected seeds/seed lot may fail to
germinate, cause infection to seedlings and growing plants. For good crop, good seed is essential which
indicates that the seed should be pure, viable and healthy (Khanom, 2011). The government of Bangladesh
has considered the seed sector as high priority area. Although the seed system is at a very rudimentary
stage, a total of 5 lakh tons of seeds including the seeds of cereals and other crops per year is required, out
of which only 18% seeds are produced by different seed organizations with care but almost regardless of
the health status. The rest 82% of the seeds retained by the farmers remain uncertified with unknown
quality and outside the supervision of Seed Certification Agency (Fakir, 2000). Ten different types of fungi
have been reported from 16 vegetable crop seeds collected from different shops of Mymensingh Sadar
(Hossain and Purnima, 2011). In fact, this is actually an alarming situation in the country. The lack of high
quality seeds and the prevalence of the seed borne organisms are the main constraints in maintaining the
crop production (Fakir, 2000). Use of quality seeds can alone meet the loss. The lack of high quality
healthy seeds and the prevalence of seed borne diseases are among the main constrains for Bangladesh in
