Abstract:
The experiment was conducted at the farm of Sher-e-Bangla Agricultural University, Dhaka,
Bangladesh during the period from January, 2018 to July, 2018 to find out the effect of Calcium
(Ca) and Sulphur (S) on the morpho-physiological characters and yield of mung bean. BARI mug6,
high
yielding
variety
was
used
in
this
experiment
as
the
test
crop.
The
tallest
plant
was
recorded
as 34.05 cm, 47.42 cm and 52.27 cm from T
6
(100 ppm Ca +100 ppm S), T
(100 ppm Ca) and
T
5
ii
1
(100 ppm Ca +50 ppm S) at 30 DAS, 45 DAS and 60 DAS respectively. The highest number of
leaves per plant (6.67, 8 and 9.07 respectively) were recorded from the treatment of T
(100 ppm
Ca + 50 ppm S), T
1
(100 ppm Ca) and T
(100 ppm Ca). The highest number of branches per plant
(0.80, 1.20 and 1.60 respectively) were observed from T
1
5,
T
2
and T
. The highest days to flowering
(32.3) was observed from T
0
2
. The highest SPAD values at 30 DAS was 49.50 for T
, at 45 DAS
was 69.88 for T
2
and at 60 DAS 72.74 for T
2
. The highest leaf area (132.49 cm
) was obtained
from T
3
(50 ppm S). The highest number of flowers per plant (40.36) was observed from T
(200
ppm Ca + 50 ppm S). The highest number of pods per plant (28.33) was observed from T
(200
ppm Ca + 50 ppm S). T
(200 ppm Ca + 50 ppm S) treated plants took the minimum number
of days to first ripening of fruit and to 50 % maturity of fruit and T
7
(100 ppm Ca + 50 ppm S)
treated plants to 100 % maturity of fruit 49.33, 67.00 and 70.66 days respectively. The highest no.
of fertile seed was observed as 145.40 for T
0
5
. The highest weight of 1000 seeds (51g) was
recorded from T
(100 ppm Ca + 50 ppm S). The highest seed yield 1615.13 kg/ha was gathered
from T
5
5
(100 ppm Ca + 50 ppm S). Whereas the minimum yield 1041.31 kg/ha given by T
(no
treatment) which was statistically similar with 1122 kg/ha of T
(50 ppm S). The highest harvest
index 62.86% was gathered from T
8
3
(200 ppm Ca + 100 ppm S) which was statistically similar to
61.65% recorded from T
(100 ppm Ca + 50 ppm S). Whereas the minimum harvest index 51.04%
given by T
1
5
(100 ppm Ca) . It can be concluded from the above study that application of the
treatment T
(100 ppm Ca+ 50 ppm S ) was found to be the most suitable combination for the
higher performances of mung bean.
