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.

Potato, phosphorus

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

5.

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.
