Abstract:
An experiment was conducted at the experimental field of the Department of
Agronomy. Sher-c-Bangla Agricultural University. Dhaka to evaluate the
effect of nitrogen and weed managements on mungbean
(Vigna rac/iala L)
during the period from March 2007 to June 2007. Different managements of
nitrogen (0. 20 kg N hi' at vegetative, 20 kg N hi' at vegetative and
flowering) and weeding (No weeding, one weeding at vegetative, two weeding
at vegetative and flowering stage) were integrated. Results showed that
application of 20 kg N hi' as basal + 20 kg N ha
4 with one weeding at
vegetative stage showed significantly higher values of all growth parameters
like number of leaflets (24.27 at 20 DAS and 24.27 at 40 DAS), leaf area
(23.27cm2 at 20 DAS and 102.17 cm
2
at 40 DAS), leaf dry weight (0.30, 6.99
and 10.61gm at 10, 17 and 24, DAS respectively) and shoot dry weight (2.76
and 4.69 gm at 17 and 24 DAS. respectively). This treatment also produced
significantly more number of branches (1.67), pods plant
1 (17.83) and seed
yield
hi'(1982.05
kg). Mungbean yield was attributed to shoot dry weight,
pods plani' and I 000-seedweight and shoot dry weight.
