Abstract:
A pot experiment was carried out at the net house of the Dept. of Agronomy, Sher-eBangla
Agricultural University, Dhaka during the period from November 2015 to
March 2016 to study the effect of boron (B) application at seedling and tillering stages
on the grain yield of two wheat varieties. The experiment consisted of three levels of
boron viz. 0, 0.50 and 1 kgBha
-1
and two wheat varieties viz. BARI Gom 23 and
BARI Gom 24. The effect of B on different plant characters, yield components and
yield of wheat was found significant. The tallest plant (53.17 cm) was found when the
crop was fertilized @ 0.5 kgBha
-1
which was statistically identical with 1 kgBha
and
the shortest plant height (39.56 cm) from control at 40 days after sowing in tillering
stage. The highest seed weight plant
-1
(10.67g) was found in BARI Gom 24 at tillering
stage with the application of boron @ 0.50 kgha
-1
. The highest 1000 grain weight
(46.62 g) was found by applying B @ 0.5 kgha
-1
and the second highest 1000 grain
weight (40.82 g) was found from control. The production of highest straw yield was
(6.15 tha
-1
) in 1 kg B ha
-1
might be due to the fact that B tends primarily to encourage
vegetative growth. The highest biological yield (10.53 tha
-1
) was found in BARI Gom
24 with the dose of 0.5 kgha
-1
, whereas the BARI Gom 23 showed 9.43 tha
. The
highest biological yield (7.92 tha
-1
) and the lowest (6.94 tha
-1
) were found in tillering
and seedling stage, respectively.
0.5 kgBha
-1
The highest harvest index (43.62%) was observed in
which was statistically similar (41.82%) with 1 kgBha
-1
and the lowest
(39.94%) was found from the control. The BARI Gom 24 showed the maximum
harvest index (44.10%) with the application of 0.5 kgBha
-1
, whereas BARI Gom 23
showed the nearest result (43.14%).
