This year, we used a unified approach to foliar nutrition of most of our sunflower trial fields. The scheme included treatment with phosphite and boron fertilizers in the phase of 3-5 pairs and 6-8 pairs of leaves (ECOLINE Boron (Organic) / ECOLINE Boron (Premium), GROS Phosphito-NP / ECOLINE Phosphite (K) / ECOLINE Phosphite (K-Amino)) + complex of microelements in the phase of flower formation (ECOLINE Oilseed (Chelates)). Under conditions of stress, of course, the fertilizers with amino acids were chosen.Compared to the untreated plots, we have observed better developed plants, larger and better filled flowers, but the most important argument in favor of this approach was a stable increase in yield of 3-4 dt/ha on all the fields without exception.
Try it and see for yourself, and we will be happy to help you choose products for your growing conditions!
