Abstract:
The experiment was carried out in a typical rice growing soil of Sher-e-Bangla
Agricultural University, Dhaka, during the period from 24
th
July to 24
November
2014 to study the effect of zinc and boron on the growth and yield of T. Aman rice
(BRRI dhan34). The experiment was laid out into Randomized Complete Block
Design (RCBD) with three replications. Two factors were comprised with study
viz. factor A: B
0
= 0 kg B ha
-1
, B
1
= 2 kg B ha
-1
and B
2
= 4 kg B ha
and Factor B:
Zn
0
= 0 kg Zn ha
-1
, Zn
1
= 2 kg Zn ha
-1
and Zn
2
= 4 kg Zn ha
-1
. Data were recorded
on different growth, yield and yield contributing parameters. Most of the
parameters showed significant difference among the treatment. Results indicated
that the highest straw weight ha
-1
(8.07 t) was recorded from B
1
Zn
; the number of
total tiller hill
-1
(19.81) and effective tiller hill
-1
1
-1
th
(14.53) were received from B
.
Again, the highest panicle length (25.28 cm), filled grain panicle
-1
(143.60), total
grain panicle
-1
(161.40), grain weight ha
-1
(5.72 t ha
-1
) and harvest index (45.77 %)
were recorded from B
2
Zn
2
.
The highest plant height (132.30 cm), non effective
tiller hill
-1
(5.55) and un-filled grain panicle
-1
(56.52) were achieved from the
treatment combination of B
1
Zn
2
, B
0
Zn
2
and B
0
Zn
respectively. The treatment
combination B
2
Zn
2
0
performed better for increasing the yield of T. Aman rice and
improved the nutrient status of post harvest soil of AEZ 28.
