The biological peculiarities of all bread cereals have much in common. The root system is fibrous.
The roots can be primary (embryonic) and secondary (basic). 90% of the root system is in top soil.
Grain crops growth and develop in phases. The majority of grain crops has the following phases:
Seedlings — the first green leaves appear at 7-10 day after seeds sowing;
Tillering — 10-20 more and plants have the first side shoots and the secondary nodal roots;
Stem elongation in 12-18 days after tillering.
Flowering and ripening are the final phases.
It is the most reasonably to perform the top-dressing with the “Riverm” fertilizer in the period of tillering and stem elongation. It shall provide not only photosynthesis surface increasing, but a strong development of the secondary root system which in future will increase plants drought resistance.
