In order to determine the effect of the phosphoric element on the growth and development of
potatoes, their productivity and efficiency, studies were conducted to determine the optimal
nutrient medium in laboratory and field conditions. In nutritional variants with a concentration of P
of 16 mg / l and 48 mg / l, the P content is higher than in leaves. In nutritional variants with a
concentration of 48 mg / l, there is a smaller number of leaves compared to the 16 mg/l
concentration variants and a delay in the flowering period. It was found that the nutrients contain
important vital microelements in plant tissue and the output composition in variants of the
concentration of P is 16 mg /l.
The results of phenological observations
over growth and development of
potatoes under the influence of different
concentrations of КH2PO4 increasing
number of leaves in variants of the
phosphorus concentration of 16 mg/l, and
the length of the flowering period
corresponds to the period of vegetative
development.
To positively implement the interaction of
micro - and macronutrients, which play an
important role in the growth and
development of potatoes, it is desirable
to maintain the pH of the soil from 6.0 to
In nutritional variants with a
concentration of 16 mg/l And 48 mg / l,
the pH content in the leaves is higher.
But, despite the high content indicators,
in the nutritional variants with a
concentration of 48 mg/l, there is a
smaller number of leaves compared to
the variants with a concentration of 16
mg/l, and the flowering period is delayed.
