| dc.description | Chilli (Capsicum annum L.) is one of the most popular and important
spices crops in Bangladesh. In Bangladesh 55,000 acres land is under its
cultivation and total production is 2,94,000 t. per annum approximately (BBS,
2008). Nutritive value of Chilli is high as it contains 1.29 mg protein, 11 mg
calcium, 870 I. U. vitamin-A, 17.5 mg ascorbic acid, 0.06 mg thiamine and 0.03
mg riboflavin and 0.55 mg niacin per 1.008g edible fruit (Joshi and Singh,
1975). It is not only important crop in Bangladesh but also widely distributed all
over the world. The soil and climate of Bangladesh are very favourable for the
cultivation of Chilli, but the crop cultivation is hampered by the attack of several
species of nematodes (Timm and Ameen, 1960). Moreover, the nematode
population in the soil of Bangladesh is increasing day by day (Chowdhury,
1976). Plant parasitic nematodes especially root-knot nematodes are associated
with many solanaceous crops especially with Chilli (Deshmukh e7 a/.1988.
Anwar, 1977, Qmar et al.1985). The soil and climatic condition of Bangladesh
has made her a real abode for nematodes. It is reported that 15 genera of plant
parasitic nematodes are associated with commercial crops in Bangladesh, where
Meloidogyne spp. are more abundant and widespread (Timm and Ameen, 1960).
Among the different types of diseases caused by nematodes, the root-knot
caused by Meloidogyne spp. is the most serious one having worldwide
distribution. Root-knot nematode is an economically important disease to the
growers in Bangladesh. The common species of root-knot nematode in
Bangladesh are Meloidogyne javanica, Meloidogyne incognita and Meloidogyne
graminicola. They attack wide varieties of field, fruit and vegetable crops
causing considerable damage to the crop. They may occur independently or in
association with fungal or bacterial pathogens (Singh, 1973). | en_US |
| dc.description.abstract | Five treatments viz. BAU-Biofungicide (7richoderma spp.), Kharazora
(Teinostachynum griffithii), Upotlangra (Aschyranthus aspera) and Satodron
(Leucas aspera) along with a control were tested against root-knot of Chilli
caused by Meloidogyne javanica. Among the treatments, BAU-Biofungicide and
satodron leaf extract gave superior result as it had increased shoot and root
length, fresh weight of shoot and root as well as number of fruit and fruit weight
correspondingly with the lowest galling incidence in Chilli. Better effect on plant
growth characters and yield with lower galling incidence and development of the
nematode was observed with Kharazora and Upotlangra leaf extract compared to
control. Negative correlations between gall numbers with shoot and root length,
shoot and root weight as well as number of fruit and fruit weight under different
treatments indicated the superior effect of the treatments as envisaged with lower
galling and the suppressive activities of the nematode. | en_US |
