| dc.description | Tomato (Lycopersicon lycopersicum L.) is one of the most important
and popular vegetables in Bangladesh. It is an important vegetable for its
special nutritive value and its wide-spread cultivation. It ranks the second in
importance to potato in the tropics on the basis of production and economic
importance. In Bangladesh 18.5 thousand hectares land is under its cultivation
and the total production is 122 thousand metric tons per annum approximately
(BBS, 2006). Tomato is grown as winter vegetables in an area of 8817 ha and
the production of tomato in our country is only 7.9 ton/ha (Anon, 1981),
whereas its production in Taiwan is 102 thousand metricton in a year (2002-
2003).Tomato is favored by its diversified use like salad, juice, pickle and other
preserved items. It contains high nutritional values with 1.98 g protein, 320 IU
vitamin-A, 1.8 mg iron and 31mg vitamin-C in 100g edible tomato (Bose,
1986). It is equally preferred from the richest to the poorest people of our
country due to its good taste and easy availability. But its total production in
Bangladesh is low as compared to other tropical country (FAO, 1988).In a
survey Sam (1979) noted that tomato is affected by root-knot nematodes
(Meloidogyne spp.) throughout Bangladesh causing appreciable yield loss. A
loss estimate study conducted under inoculated condition showed that about
40% yield of tomato was reduced due to incidence of root-knot disease (Anon.,
1981). As vegetable crops, the popularity of tomato is increasing day by day in
our country. Now-a-days many of the amateur gardeners are growing
horticultural crops like tomato in their roof gardens as a hobby and to bring
solvency in their family to some extent. But the production is limited because
tomato is attacked by some soil-bone diseases specially root-knot nematode
(Meloidogyne incognita). The common species of root-knot nematodes in
Bangladesh are Meloidogyne javanica, Meloidogyne inconita, and
Meloidogyne graminicola. More than 37% yield reduction of tomato due to | en_US |
| dc.description.abstract | Standard extracts of Bashak (Adhatoda vasica) and Pineapple (Ananas
sp.), Pineapple (A4nanas sp.) and Mustard oil cake (Brassica campestris),
Mustard oil cake (Brassica campestris) and Neem (Azadirachta indica), Neem
(Azadirachta indica) and Dholkalmi (/pomoea fistulosa), Dholkalmi (Jpomoea
fistulosa) and Marigold (Tagetes patula), Marigold (Tagetes patula) and
rhizome of Ginger (Zingiber officinale) and all standard extracts along with a
control were tested against root-knot of tomato caused by Meloidogyne
javanica. Among the treatments, Bashak leaf extract and Pineapple extract
gave superior result as it had increased shoot and root length as well as fresh
weight of shoot and root correspondingly with the lowest galling incidence and
development of L2, L3, Ly and adult female stage of Meloidogyne javanica in
tomato. Better effect on plant growth characters with lower galling incidence
and development of the nematode was observed with Pineapple extract and
Mustard oil cake followed by Mustard oil cake and Neem leaf extract. Lower
effect of plant growth characters was found with Neem leaf extract and
Dhoikalmi leaf extract followed by Dholkalmi leaf extract and Marigold leaf
extract. Marigold leaf extract and rhizome extract of Ginger as well as all
standard extracts were also found effective compared to control. All extracts
performed better in root dipping method than any other extracts used in seed
treated method. Negative correlations between gall number with shoot and root
length, shoot and root weight as well as positive correlations between gall
number with eggmassess, L, and adult female under different treatments
indicated the supcrior cffcct of the treatment as cnvisaged with the lowcr
galling followed by the suppressive activities of the nematode. | en_US |
