Abstract
An experiment was conducted in the research laboratory of the department of
Agricultural Chemistry, Hajee Mohammad Danesh Science and Technology
University, Dinajpur, during March 2011- March 2012 to study the effects of
aqueous leaf extracts of some herbal plants on the germination and seedling
growth of vegetables. The treatments were T, -Water or control,T,;-Aqueous
extract of basak,T,= Aqueous extract of ulot komal,T;=Aqueous extract of neem,
T, = Aqueous extract of bel,T;-Aqueous extract of akando and Ts=Aqueous
extract of horitoki. The experimentwas laid out following CRD with three
replications. Cucumber, lady’s finger and yard long bean were selected.
Significantly the fastest 50% germination occurred with horitoki (Ts = 4.33 days)
followed by T, T3, Ty and T; where as the slowest 50% germination occurred with
control (Tp =6.33 days). At 20 DAS, 25 DAS and 30 DAS the highest shoot length
was recorded in case of seed treated with horitoki leaf extract (44.27 cm, 62.17 cm
and 83.10 cm, respectively). Horitoki showed the best result (8. 67 cm) whereas
control showed the lowest root length (5.73 cm) followed by seed treated with
basak leaf extract
Description
Agrochemicals research in recent years has advanced immensely in
discovering very active and safe chemicals and also integrating
chemicals discovered to project the shape of things to come and show
that the discovery of agrochemicals today is no longer a trial and error
business but a real science combing advances from many different
disciplines. There is so much hope and optimism in the agrochemical
field world wide. The research effort yielding this new high potency,
safe agrochemicals have indeed become very complex. The random
approach of synthesizing a large number of compounds and discovering
an active one is no longer cost effective.
