While the fields are still covered with snow, we have time to remember valuable information: what exactly and when we can still do to maximize the harvest in this difficult season.
1. Tillering (ВВСН 21-29), which will be relevant for late sowings – the number of segments of the ear stem and the length of the ear are formed. We can improve these indicators due to the use of nitrogen fertilizers with sufficient phosphorus-potassium agrophone and foliar fertilization with trace elements (Zn, Cu, Mn).
2. Stem elongation (ВВСН 30-32) – the number of ears in the ear is formed – timely application of fertilizers can double the number of grains in the ear, therefore, balanced foliar application of NPK+ME and the use of biostimulants to optimize the nutrition system are important. After this stage, it is no longer possible to influence the size of the ear and the number of ears.
3. Second node of stem visible (ВВСН 32-33) – flowers are laid in spikelets and spikes. Optimizing nutrition during this period will lead to laying more developed flowers. When increasing their number to 4-5 in a spikelet, unlike the usual 2-3, it is possible to double the yield.
4. Last leaf just vivsible (ВВСН 33-35) – the formation and development of flowers takes place, the differentiation of the ear ends. Optimum phosphorus nutrition, which has a positive effect on the development of generative organs, becomes more important.
5. Stem extension (ВВСН 35-39) – the density of the ear is formed, which is still in the sheath of the leaf. During this period, optimization of nutrition (including through foliar feeding) will help to avoid the phenomenon of a loose ear.
6. Heading (ВВСН 51-59) – the formation of ears and flowers ends. The upper internode is growing. Timely nitrogen feeding will help to increase the content of protein and gluten.
7. Flowering (ВВСН 61-69) – growth of vegetative mass stops. It is possible to improve the passage of this stage by using anti-stress products, amino acids at the previous stage.
8. Grain formation (ВВСН 70-72) – the grain acquires a finite length. If necessary, with a good photosynthetic surface and moderate moisture, we can use products containing nitrogen and amino acids to improve the quality characteristics of the grain.
9. Milk ripeness (ВВСН 73-77) –the mass of 1000 grains and the nature of the grain are formed. The thickness and width increases. By optimizing nutrition, we continue the activity of the photosynthetic apparatus. The use of amino acid products and complex nutrition is possible, provided that it is economically justified.
10. Ripening (ВВСН 83-87) – the grain stops increasing in weight and size. Nutrients are converted into reserves.
So, summing up all of the above: before flowering we work on the quantity of harvest, after flowering – on quality! It is worth remembering these main points in order to make each of your treatments as effective as possible!
