| dc.description | Mustard (Brassica campestris L.) is the important oil seed crop of
Bangladesh. It grows all over the country and meets up a major part of our
edible oil. Its total production is 887 thousand metric tons in 376 thousand
acres of land (BBS:2010). Among the different varieties Daulat, BD-7809,
BARI-9, BD-7134, BD-7137, SS-75, etc. are very popular. Although it is an
important crop of Bangladesh, diseases of this crop attain very little
attention. The yield of this oil seed is too low in Bangladesh compared to
the developed countries of the world. Every year huge amount of edible oil
is imported from different countries with considerable amount of foreign
currency. Thus, there is a great need for increasing the yield of mustard in
our country. Among the various constraints different seed-borne diseases
play an important role in reducing the yield of mustard. Seed-borne diseases
cause enormous losses to our crops (Fakir, 1982) as seed acts as reservoir of
virulent pathogens (Neergaard, 1979). | en_US |
| dc.description.abstract | Mustard seeds were collected from farmers’ level in different locations of
Bogra and Sirajgong districts to study the health status, quality, germination
percentage and to investigate the effectiveness of using plant extracts and
Provax 200wp as seed treatment. The experiment was conducted at Hajee
Mohammad Danesh Science and Technology University during the period of
July 2010 to February 2011. The seed samples were tested following dry
inspection and blotter method. Apparently healthy seeds were highest (75%) at
BD- 7137 and lowest (50%) at variety Daulat. In blotter test among 11 mustard
varieties the highest number of germination was recorded from the seeds of
BD-7137 (87.33%) and the lowest was recorded from Daulat and BARI-8
varieties (50.67%) after 7 days of incubation. Different seed-borne fungi such
as Alternaria spp., Aspergillus flavus, Rhizopus stolonifer, Fusarium
oxysporum, Bipolaris spp. and Curvularia lunata were found associated with
the mustard seeds. Percent germination and percent seed borne infection of
fungal pathogens were different with treatment of different plant extracts and
provax 200wp. Percent germination was observed highest in Provax 200 wp
seed treatment (80%). Garlic plant extract was found most effective among
three treatments for increasing the germination percentage as well as for
controlling the associated fungal pathogens in mustard seeds. Prevalence of
different fungi varied from variety to variety. Minimum infection was found
when seeds were treated with garlic clove extract in variety BD-7137 of
mustard. | en_US |
