The yield and quality of carrot is limited due
to the imbalance application of macro and
micronutrients. The experiment was conducted at
Horticulture farm of Kawasoti, Nawalparasi to assess
the effect of different levels of potassium and boron on
growth, yield and quality of carrots, during the period
from 20th November, 2019 to 5th March, 2020. The
experiment was laid out in RCBD design allocating 12
treatments and 3 replications. The treatment comprised
of three different levels of potassium (i.e. 0, 50 and 100
kg/ha) and four different levels of boron (i.e. 0, 1.1, 2.2
and 3.3 kg/ha). The variety ‘New Kuroda’ was used in
the experiment. The result of present study indicated the
significant effect of different treatments on growth, yield
and quality of carrot. The maximum plant height (51.67
cm), number of leaves (11.55) , root length (19.37 cm),
root diameter (4.81 cm), fresh weight of leaves (81.11
gm) , fresh weight of roots (207.66 gm) and yield per plot
(11.10 kg) was observed with the application of
Potassium @ 100 kg/ha and boron @ 3.3 kg/ha. Besides,
maximum value of quality parameters like TSS (11.50
˚B), carotene content (6.367 mg/100 gm) and ascorbic
acid content (3.720 mg/100 gm) was also observed with
increase in levels of potassium and boron, whereas the
minimum value for all the parameters were observed
from control treatments. Considering these positive and
beneficial effects of optimum levels of potassium and
boron, it can be concluded that the application of
potassium @ 100 kg/ha and boron @ 3.3 kg/ha was
found beneficial for carrot production. Therefore, based
on the present findings of the study, combined
application of micronutrients along with major nutrients
was found better for the optimum yield and quality
carrot production in Nawalparasi.
