2.4 The effect of the Nano-Gro® preparation on the seeding value of winter wheat cultivars
Table 9 shows the effect of the preparation on the seeding value of winter wheat grain of the cultivars under study. The Nano-Gro® preparation was not found to have any adverse effect on the seeding value of the grain. The germinating energy and power was very high; it was similar to that of the grain harvested from the control plot and from those plots on which Baytan Universal 19,5 DW was applied (Table 9). The growth power determined in the experiment indicates that the grain harvested from the plots where Nano-Gro® was applied had good vitality, which is indicated by a high growth power and green matter of seedlings. (Table 10).

The Nano-Gro® preparation which was evaluated in this study caused an increase in green and dry matter content in the aboveground parts and roots. The increase was especially high during the initial phases: tillering and shooting.
A positive effect of the preparation resulted in a reduced plant loss during the vegetation period, higher productive tillering, thereby significantly and positively affecting the number of ears per unit area and grain yield per ear.
A positive effect of the Nano-Gro® preparation on the yield structural features resulted in significantly higher grain yield in the cultivars under study, both as compared to the control plot and to that on which Baytan Universal 19,5 WS was applied.
An analysis of the technological value showed beyond doubt that that the preparation did not have any adverse effect on the grain usability for milling or baking, even improving some features like gluten content and its quality. Therefore it can be concluded that Nano-Gro® may be used in wheat production for consumption, i.e. as a raw material for the production of flour used for baking.
Another analysis showed that the seeding value of the grain harvested from the plots where Nan-Gro® was applied was very high.
The Nano-Gro® preparation may be successfully applied as a biostimulant in the production of winter wheat.
