Abstract:
A field experiment was conducted at Sher-e-Bangla Agricultural University Farm, Dhaka during
the period from April 2017 to July 2017 to study the response of mungbean (BARIMung-6) to
zinc, boron and molybdenum application.The single factor experiment was consisted with eight
treatments viz., T
1
= Control, T
2
= Zn 2.0 kg ha
-1
, T
3
= B 1.5 kg ha
-1
, T
4
= Mo 1.0 kg ha
=
Zn+B, T
6
= Zn+Mo, T
7
= B+Mo and T
= Zn+B+Mo.The experiment was laid out in Randomized
Complete Block Design (RCBD) with three replications. Results showed that plant height,
number of branches plant
-1
8
, pod length, number of pods plant
-1
, number of seeds pod
, grain
yield, stover yield, biological yield, harvest index and available phosphorous and exchangeable
potassium content of post-harvest soil was significantly influenced by zinc, boron and
molybdenum application.Among the different treatments T
(2kg Zn+1.5 kg B+1 kg Mo)
treatment produced tallest plant (44.40 cm), highest number of branches plant
8
(9.5), maximum
number of pods plant
-1
(13.0), maximum length of pod (9.60 cm), maximum number of seeds
pod
-1
(10.00), highest 1000 grain weight (50.80g), highest grain yield (1.40 t ha
) and maximum
harvest index (52.84%).This combination also exhibited highest pH (6.05), organic matter (1.39
%), total nitrogen (0.092%), available phosphorous (23.45 ppm) and exchangeable potassium
content (0.24 meq/ 100 gm soil) of post-harvest soil. On the other hand, T
(Control) treatment
produced lower values in all cases except stover yield and harvest index. From the growth, yield
and post-harvest soil analytical reports, it is apparent that the combination of 2kg Zn+1.5 kg B+1
kg Mo (T8) was suitable for mungbean cultivation
