planting of plants at key periods of the growing season. We have conducted research
in this direction and continue to perform it on a number of crops: barley, wheat,
triticale, red, soybean, peas, chickpeas, sunflower and other spring and winter crops.
The effectiveness of this approach to nutrition optimization is shown by the example
of spring wheat (Fig. 2).
These data convince of a significant increase in grain yield in comparison with
inconvenient control. Moreover, from application to sowing of N
30
P

it increased on
average over the three years from 1.72 to 2.72 g/ha. Maximum yield values are reached
for nitrogen fertilization on the background of N60 P30 just in time for planting (3.26
t/ha) and N30 P30 before sowing + N
30
at the feeding in the early exit of plants in the
tube (3.30 t/ha). Almost at the same level, it was formed by double treatment of plants
with D2 (3.08 t/ha) and escort (3.10 t/ha).
With presowing treatment of seeds with an escort, the grain yield was formed
even higher, which is convincingly illustrated by Fig. 2.

phase 2-the beginning of earing
