Abstract
The objective of the study was to evaluate the effect of Nitrogen and
biofertilizer on the morphophysiological traits and yield performance of
mungbean. The experiment was conducted in research field of the Department of
Crop Physiology and Ecology, Hajee Mohammad Danesh Science and Technology
University, Dinajpur, during the summer season from February to June 2011.
Five mungbean varieties viz. BARI Mung-2, BARI Mung-3, BARI Mung-4,
BARI Mung-5 and BARI Mung-6 and three fertilizer viz. nitrogen (urea),
biofertilizer, and a control were used as treatment. The experiment was laid out in
Randomized complete Block Design (RCBD) with three replications. Experiment
showed that most of the morphophysiological characters, such as plant height,
shoot dry weight, root dry weight, leaf dry weight, total dry matter, number of
nodule plant”',leaf area increased significantly due to application of nitrogen. The
above parameters were the maximum when the mungbean varieties were treated
with nitrogen followed by biofertilizer. Yield and yield contributing characters
such as number of flowers plant’, number of pods plant”, pod length (cm), pod
dry weight (g/plant), number of seeds pod", 100 seed weight, seed yield (g/plant),
seed yield (kg/ha), Harvest index(%) etc. were increased significantly by the
application of nitrogen and biofertilizer over the control. But abscission (%) was
decreased significantly due to application of nitrogen and biofertilizer. BARI
Mung-5 performed better than other 4 varieties in respect of plant height, root dry
weight, leaf dry weight, total dry matter, leaf area, pods plant’, pod length (cm),
pod dry weight (g/plant), number of seeds pod’, 100 seed weight, seed yield
(g/plant), seed yield (kg/ha).The variety BARI Mung-5 and BARI Mung-6 had
higher harvest index (%) than BARI Mung-4, BARI Mung-3 and BARI Mung-2.
The maximum seed yield was found in BARI Mung-5 with nitrogen and
minimum seed yield was found in BARI Mung-2 in control.
Description
Bangladesh is a agrobased country with land and very high population. Due to our
huge population we have to produce more food in our limited land. To meet the
increased demand of food, farmers are growing more cereal crops. Due to the high
population pressure, the total cultivable land is decreasing day by day for housing.
So, at present the cultivation of pulse has gone to marginal land because any one
does not want to use his fertile land in pulse cultivation. Pulse cultivation is also
decreasing because of its low yield & low production. Besides this long term
cereal crop cultivation also affects soil fertility and productivity which could be
overcome by growing pulses.
