Abstract
The field experiment was therefore conducted to investigate the
influence of potassium and boron on the quality and yield of tomato at
the Horticulture farm of the Sher-e-Bangla Agricultural University,
Dhaka, during the rabi season (October 2019 to March 2020). The
experiment consisted of two factors, Factor A: four different levels of
potassium (K
O) viz., 0, 80, 120, 140 kg/ha, Factor B: four different
levels of boron (B) viz., 0, 0.6, 1.2, 1.8 kg/ha. The experiment was
comprised of 16 treatment combinations and laid out in Randomized
Complete Block Design (RCBD) with three replications. The influence
of different levels of potassium, boron and their combined effect showed
significant variations in quality and yield of tomato. Plant grown with
120 kg /ha K

O gave the highest result in number of leaves per plant
(40.52), number of flower clusters per plant (8.32), number of flowers
per cluster (6.59), number of fruits per cluster (4.54) , number of mature
fruits per plant (37.93), weight of fruits per plant (0.95 kg), weight of
fruits per plot (5.68 kg), yield per hectare (63.19 ton/ha) as well as
quality parameter total soluble solids % (7.84), β -Carotene mg per 100g
(0.36) and Vitamin-C mg per 100g (112.6). Among the different levels
of boron maximum results were obtained from 1.2 kg B/h in all yield and
quality parameters except plant height. In combine treatments the
maximum plant height (119.2 cm), number of leaves per plant (42.92),
number of flower clusters per plant (8.93), number of flowers per cluster
(7.44), number of fruits per cluster (4.79), weight of fruits per plant (1.07
kg) were produced from the treatment combination of 120 kg K/ha with
1.2 kg B/ha. The highest fruit yields per plot (6.42 kg), per hectare
(71.33 t) as well as quality were achieved from the treatment
combination of 120 kg K

O/ha with 1.2 kg B/ha. So, optimum use of
potassium with the combination of micro nutrient boron could
influence quality and yield of tomato significantly.
