Abstract:
The experiment was carried out in a typical soil of Sher-e-Bangla Agricultural
University, Dhaka, during the period from November 2019 to March 2020 to study
the Influence of Boron Application Methods on Morpho-physiological Attributes and
Yield of Wheat (Triticum aestivum L.). The experiment was laid out Randomized
Complete Block Design (RCBD) with three replications. The treatments were T
0
:
Control, T
1
: Soil application of 2 kg/ha B, T
2
: Seed priming, T
3
: Foliar spray at
primordial stage, T
4
: Foliar spray at booting stage, T
5
: Foliar spray at primordial and
booting stages, T
6
: Foliar spray at grain filling stage. The rate of Boron for soil
application was 2 kg/ha B from boric acid (17% B), the rate for each foliar spray was
0.4% boric acid solution and seed priming was done by soaking wheat seeds into
0.1% boric acid solution. Data were recorded on different growth, yield and yield
contributing parameters. Most of the parameters showed significant difference among
the treatments. Results indicated that the highest plant height (94.467 cm), maximum
total no. of tiller hill
-1
(3.7000), longest length of flag leaf (23.393 cm), highest
breadth of flag leaf (2.6267cm), longest spike length (12.887 cm), maximum no. of
total grain spike
-1
(68.867), maximum no. of filled grain spike
-1
(67.733), maximum
spikelet fertility (%) (98.353), maximum thousand grain weight (52.667 g),
maximum total Grain weight ha
-1
(2.8945 t ha
-1
), maximum straw yield (3.2611 t ha
)
were found in T
5
treatment (Foliar spray at primordial and booting stages, 0.4% boric
acid). Maximum leaf no. plant
-1
(12.783) were found in T
1
treatment (Soil application
of 2 kg/ha B). And, highest the SPAD value (51.063), no. of effective tillers plant
were (2.6667) found in T
6
treatment (Foliar spray at grain filling stage, 0.4% boric
acid). Once more, the highest no. of in-effective tiller hill
-1
(0.1733), un-filled grain
spike
-1
(2.1900) was recorded from T
0
treatment (Control).
