Studies with growth-regulating drugs were conducted in 2016-2017 with two
varieties of spring barley – Stalker and Vakula. In addition to D

fresh florid was used to optimize nutrition in doses of 200 and 300 g / ha and Fresh
energy (200 g/ha), which are recommended for spring barley. On average, over the
years of research Stalker provided in the control of 2.78 t/ha, Vakula – 2.77 t/ha of
grain, with the use of all studied biopreparations on average for all 15 options, the yield
increased to 3.59 t/ha and 3.57 t / ha or increased to control without fertilizers by 29.1
and 28.9%, respectively. However, it should be noted that in 2016, the higher grain
yield was formed by the Vakula – 4.31 t/ha (the weighted average for all variants of
the experience), and in the arid 2017 – only 2.73 t/ha (Table 4). That is, the sort of
spring barley Stalker is more plastic and is able to form a stable performance with less
dependence on weather and climatic conditions of the year.
Similar results were obtained in the treatment of seeds and plants with bio
substances in the cultivation of two varieties of peas Oplot and Tsarevich, the yield of
which for three years from these substances increased by an average of 28-30%. At the
same time, as in the cultivation of spring crops, the main indicators of the quality of
pea grain are significantly improved, the number and mass of nodule nitrogen-fixing
bacteria on the roots of plants increases, moisture is effectively used, the cost recovery
for the introduced resource-saving measures in the cultivation of this legume crop
increases. Similar results were obtained on two varieties of chickpea-Rosanna and
Memory.
The same data on the optimization of nutrition through the use of bio substances
were obtained for the cultivation of sunflower (grade Dragan). Also in studies
conducted in 2016-2017 without fertilizers formed 2.45 t/ha, on the background of the

(100 kg/ha of NPK) – to 2.94 t/ha, and in the processing plants
in the phase of 8-10 leaves and education of the basket, depending on the selection
Restigouche substances from of 3.02 to 3.48 t/ha. Under the influence of this measure
increases the mass of 1000 seeds, test weight, fat content in grain and the conditional
yield of oil per unit area, and alcalinity, on the contrary, decreases.
Thus, as it is known and confirmed by our studies with many crops, to increase
their productivity and main indicators of the quality is possible by the application on
the background of moderate doses of fertilizers and modern growth-regulating
substances. This measure provides nutrition of young plants with macro-,
microelements and partially organic matter (humins) through leaves. The assimilation
of all nutrients with this approach increases significantly, which in turn contributes to
the development of plant specific substances and proteins that increase their resistance
to disease, drought, high temperatures and the like.
