Abstract
Four treatments viz. curaterr solution, standard (S) leaf extracts of neem
(Azadirachta indica), marigold (Tagetes erecta) and dhalkalmi (Ipomoea
fistulosa) with a control were tested against root-knot of brinjal caused by
Meloidogyne javanica. Among the treatments, curaterr solution gave superior
result followed by neem leaf extract (S) in plant growth as they had increased
length of shoot and root as well as fresh weight of shoot and root and yield
correspondingly with the lowest galling incidence. Better effect on plant
growth characters with lower galling incidence observed with marigold leaf
extract (S). Dhalkalmi leaf extract (S) was found effective in suppressing the
nematode activities as evident with moderate growth of plants. Negative
correlations between gall number with shoot and root length, shoot and root
weight and fruit weight indicate the positive response of the treatments on
brinjal against root-knot nematode (Meloidogyne javanica).
Description
Brinjal (Solanum melongena L.) is one of the most common, popular and cheap
vegetable grown throughout the all seasons in Bangladesh and mostly available
in winter season. It ranks as one of the top most vegetable in the tropics on the
basis of production and economic importance. It is highly productive and
usually finds its place as the poor man’s crop. It has food and nutritive value; in
100g of edible part of brinjal which contains carbohydrate 2.2 g, protein 1.8 g,
fat 2.9 g, vitamin 5.20 mg, iron 0.9 mg, calcium 28.0 g, water 92.4 g, ash 1.3 g,
kilocalorie 42.0 wg, carotene 850 mg (Meah,2003).
