Abstract:
A field experiment was carried out at the Agricultural Farm of Sher-e-Bangla
Agricultural University, Dhaka, during November 2017 to April 2018 to study
the effect of different levels of potassium and boron on morpho-physiology and
yield of tomato. The experiment consisted of two factors: Factor-A viz. K
(0
kg K ha
-1
), K
1
(60 kg K ha
-1
) and K
2
(100 kg K ha
-1
) and Factor-B viz. B
(0 kg
B ha
-1
), B
1
(0.5 kg B ha
-1
) and B
2
(1.0 kg B ha
-1
). The experiment was laid out
in a Randomized Complete Block Design (RCBD) with four replications. The
total treatment combinations were nine (9) and the planting material was BARI
Tomato-14. Results revealed that potassium (K) and boron (B) individually as
well as in combination showed significant variation among the treatments for
most of the parameters. Different doses of K showed significant influence on
the plant height and number of leaves plant
-1
at 50 and 70 DAT, number of
flower cluster plant
-1
, fruit diameter, single fruit weight, number of fruits
cluster
-1
, number of fruits plant
-1
, fruit weight plant
-1
and fruit yield (t ha
).
Boron application failed to show significant effect on plant height, number of
leaves plant
-1
,SPAD value, fruit length. In addition, B showed significant
effects yield contributing characters such as number of fruits plant
, fruit
diameter, fruit weight plant
-1
and fruit yield (t ha
-1
).In terms of combination
of K and B, the maximum plant height (54.60 cm) and number of leaves plant
(15.35) were achieved from the treatment combination of K
2
B
. The together
application of K
2
and B
increased the highest fruit yield of tomato which are
consistent the different morphological and yield contributing characters of this
study. Therefore, it is concluded that K in combination with B could increase
fruit yield of tomato under the climatic and adaphic condition of Sher-e-Bangla
Agricultural University (SAU).
