Abstract:
An experiment Was conducted at the experiment field of the Department of
Agronomy. Sher-e-Bangla Agricultural University: I)haka to evaluate the
ciThet of nitrogen and irrigation managements on the yield attributes and yields
of mungbean
(V/gnu rat/ia/a lj.) cv.BARI mung-5 during the period from
March 2006 to May 2006. The trial comprised often treatments such as T1

as a pulse crop showed a lag phase in early growth stage (up to 40 DAS) while
increase of growth parameters like number of leaves, leaf dry weight and steam
dry weight per plant very slow. Thus, initiation of flowers (35 DAS) caused
low dry matter production. Application of 30 kg N ha'' as basal with one
irrigation at first flowering stage (35 DAS) improved the growth parameters
significantly. This greater dry matter eventually supported the plant to produce
more number of branches and pods per plant. which resulted with maximum
seed yield per plant (5.53 g) or per hectare (1.65 ton). A Iiinctional positive
relationship was observed among number of branches per plant. pods per plant.
