Abstract
The present research work was conducted at the field laboratory, Department of
Agronomy, Hajee Mohammad Danesh Science and Technology University (HSTU),
Dinajpur during the period from April, 2018 to June, 2018 to study the effects of
different concentrations of NAA (0 ppm, 50 ppm, and 100 ppm) on growth and yield of
three mungbean varieties (BARI Mung-6, BARI Mung-7, and BARI Mung-8). The
experiment was laid out in two factors complete randomized design (CRD) with three
replications. All the collected data were statistically analyzed and the mean differences
among the treatments were compared by Duncan's Multiple Range Test (DMRT). The
results revealed that significant variations existed between the varieties in respect of
morphological characteristics and yield contributing characters like plant height, leaf
area, plant water relations, number of pods plant-1
, number of seeds pod-1
, 1000-seed
weight, seed yield, biological yield and harvest index. BARI Mung-7 produced the tallest
plant (82.00 cm), the largest leaf area (0.78 cm2
), the best plant water relations (74.57),
the maximum number of pods plant-1
(21.19), the highest number of seeds pod-1
(11.78),
1000- seed weight (295.3), the seed yield (0.65 t ha-1
), the biological yield (0.94 t ha-1
)
and harvest index (41.33%). BARI Mung-7 and 100 ppm of NAA concentration in their
combination ware recorded the tallest plant (89.77 cm), maximum stover yield (0.66),
largest leaf area (0.85 cm2
) and best of plant water relation (77.38). At the combination
of BARI Mung-7 and 50 ppm were recorded highest number of seeds pod-1
(12.23),
maximum number of pods plant-1
(29.81), highest 1000- seed weight (350.4), total seed
yield (0.85 t ha-1
) and biological yield (0.98 t ha-1
). Present study indicates that V2 (BARI
Mung-7) and N2 (50 ppm) in their combination produced the highest values for
maximum parameters. Thus, NAA (50 ppm) would be successfully used for commercial
mungbean production.
