Abstract:
A field experiment was conducted during October 2019 to March 2020 in the farm of
Sher-e-Bangla Agricultural University to study the effects of plant vitalizer (HB-101) on
growth, yield and nutrient content of tomato. The experiment consisted of two factors:
Factor A: two tomato varieties viz. V
1
: BARI tomato-2 and V
: BARI tomato-15 and
Factor B: 5 levels of HB-101 plant vitalizer viz. PV
0
2
: control (0 ml PV L
: 1 ml PV
L
-1
, PV
2
: 2 ml PV L
-1
, PV
3
: 3 ml PV L
-1
and PV
4:
4 ml PV L
-1
. The experiment was laid
out in Randomized Complete Block Design (RCBD) with three replications. In case of
different tomato varieties, the best performance for most of the parameters was obtained
from V
2
(BARI tomato-15) and gave highest yield (59.47 t ha
-1
-1
), PV
) compared to V
(BARI
tomato-2) (57.87 t ha
-1
). In case of plant vitalizer, 3 ml PV L
-1
(PV
) treatment showed
best performance and gave highest yield (62.10 t ha
-1
3
) compared to other treatments. In
case of combined treatments, V
2
PV
3
(BARI tomato-16 with plant vitalizer @ 3 ml L
)
gave highest number of fruits plant
-1
(28.80), single fruit weight (63.75 g), fruit weight
plant
-1
(1836.00 g) and yield (62.95 t ha
-1
) compared to other treatment combinations but
in case of nutrients (N, P, K and S) content in tomato fruits V
2
PV
showed nonsignificant
variation compared to other treatments. Above all considerations, treatment
combination of V
2
PV
3
(BARI tomato-15 with plant vitalizer @ 3 ml L
) can be
considered as the best then other treatments which
can be recommended for different
tomato varieties to achieve higher yield and nutrient content.
