Abstract:
An experiment was carried out at the Sher-e-Bangla Agricultural university fbirn:
Dhaka
to
investigate the nodulation, growth and yield of mungbean and blackgram as affected
by
fertilizer materials during the period from March 2007 to June 2007. The trial
comprised
of two crops and five fertilizer treatments such as C3
mungbean
and C
hlackgram, F1
= no fertilizer (control). F, = chemical fertilizer (NPKB), F.I =
inoculum. F4
cowdung, F=
PKI-
inoculum. The experiment was laid out in a split plot design with three
replications where two craps were assigned in the main plot and five fertilizer materials as the
sub-plot. Plant height. nodulation. root length. root dry weight. total dry matter production,
number of branches plant". pods plant", number of seeds pod',lOOO-seeds weight, shelling
percentage, seed yield. stover yield, biological yield and harvest index were tested for
different treatments. Results revealed that inoculum and PK+ inoculum influenced
significantly on the growth, yield parameters and yield
of
mungbean and blackgram. Plant
height, root length, number
of
branches plant" and pods plant
'
were higher in blackgram than
mungbean.
Number of nodules plant'. total dry matter production, pod length. number
of
seeds pod" and yield were higher in mungbean than blackgram. inoculum alone or in
combination with PK increased plant height. total dry matter production, leaf area index.
number of branches plant", number of seeds pod' and yield. The highest seed yield (1.59
ha") was given by mungbean with inuculum treatment that
was similar to mungbean
with PK+inoculum (1.43 t hi') and chemical
fertilizer
(NPKB) (1.33 t ha") and
blackgram with inoculum
(1.35
t ha"). The higher dry matter eventually supported the
plant to produce maximum number of
branches and pods per plant, which resulted in
maximum seed yield.
