Abstract:
Agricultural University (SAU), during October 2013 to February 2014, to study the effect
of different levels of Zinc (Zn) and Boron (B) fertilization on the grain yield of wheat
(BARI Gom-26). The experiment included four levels of Zn viz. 0, 0.02 %, 0.04 % and
0.06% Zn which were applied as foliar application and four levels of B viz. 0, 0.5, 1.0
and 1.5 kg ha
-1
which were applied as soil application. The experiment was laid out in a
randomized complete block design with three replications. The results revealed that yield
and yield contributing characters were influenced significantly by levels of zinc and
boron. The tallest plant (80.26 cm) and the highest grain yield (2.73 t ha
) were obtained
from Zn
treatment (0.04 % Zn). In contrast, the shortest plant (77.73 cm) and minimum
grain yield (2.30 t ha
2
-1
)
were observed when Zn was not applied (Zn
treatment). On the
other hand, plant height (80.02 cm) and grain yield (2.79 t ha
-1
0
-1
) were the highest when B
treatment (1 kg B ha
-1
) was imposed. The shortest plant height (76.85 cm) and the lowest
grain yield (2.35 t ha
-1
) being recorded from the control treatment B
. All the yield and
yield contributing characters were significantly affected due to the interaction effects of
different levels of Zn and B. Among the interactions, the tallest plant (83.56 cm) and the
highest grain (3.27 t ha
-1
) were obtained from combined treatment Zn
0
2
B
.On the contrary,
the lowest performances for all the studied crop characters were observed from the
treatment combination Zn
0
B
0
2
where Zn and B were not applied. The results showed that
grain yield of wheat increased with increasing levels of both Zn and B up to Zn
2
2treatment (0.04 %)
and B
2
treatment (1.0 kg ha
-1
) , respectively. The effect of B was more
prominent than with Zn on different yield components and yield of wheat.
