Minerals are
the crucial part of plant nutrition and their presence in excess or
deficiencies may cause certain maladies in the plants either through
disturbing metabolism or plant physiology abnormally by favoring the
plant pathogens or discouraging the plant growth. Potassium provides,
stress such as frost and disease tolerance ability to potato plants.
Calcium content was tested from three different samples taken at
different times, first after 50 days of planting of the crop when there
was no disease appeared while second samples were taken from healthy and
diseased plant individually, almost 30 days after the first appearance
of the symptoms on late blight. Results of present study revealed that
there was an overall increase in the quantity of calcium in all tested
lines after disease appearance. This increase was ranged from 0.4 to
45.5 percent over the healthy plants of that same age group. Maximum
increase of 45.5 percent in calcium content after disease appearance was
observed in potato line FD 70-1, while 0.4 percent decrease of calcium
content was observed in line FD 35-36. Increase in calcium content was
also observed in the healthy plants of all potato lines/cultivars which
were not infected by the disease but this increase might be due to aging
factor and was quit insignificant and unnoticeable. This increase in
calcium content of diseased plant in all lines/cultivars was
statistically significant. All though the calcium content was slightly
increased in the plants which were not diseased than that of healthy
plants which were tested at the time when disease was not appeared. It
is apparent from the above figures that the increase in calcium content
was more pronounced in moderately resistant to moderately susceptible
plants as compared to highly susceptible plants. How to cite this article: Subhani1 MN, Sahi ST, Rehman A, Wakil W (2015).
