The first fertilizer application to winter rapeseed after the resumption of vegetation in spring 2019
Winter rapeseed is a highly profitable oilseed crop whose sown area in 2018 exceeded 1 million hectares. For farmers it is extremely important to obtain a good seed yield with high quality indicators, which is possible only if rapeseed crops are supplied with the necessary macro- and microelements.
During the growing season winter rapeseed plants have a number of critical development periods, whose passage determines the laying down of the future yield level. One of them is the period from the resumption of spring vegetation to the start of flowering.
In this period plants need increased supply of the main macro- and microelements.
In the autumn-winter period of 2018–2019 winter rapeseed was under the influence of several negative factors: drought at sowing, a prolonged and excessively warm autumn, and a sharp cold snap in winter. At the stage of resumption of spring vegetation, conditions should be created for the crop to offset the negative effect of such factors and preserve the potential yield. ECOORGANIC LLC recommends using in the first feeding of rapeseed a number of special fertilizers with an immunostimulating and anti-stress effect on plants: Ecoline Phosphite (K), Ecoline Phosphite (K-Amino), Ecoline Boron (Premium), Ecoline Magnesium (Chelates).
Foliar feedings with these compositions, both on trial plots and on commercial crops in all natural and climatic zones of our country, eliminated signs of deficiency of individual mineral nutrients and gave plants a powerful start after the resumption of vegetation.
Ecoline Phosphite (K) supplies plants with phosphorus in the form of phosphite, which is available for uptake even at lowered temperatures and promotes balanced nutrition with nitrogen and potassium. Phosphorus strengthens root system growth and stimulates the production of phytoalexins in plants (raising immunity). Phosphite acts negatively on the development of fungal diseases, since it has some fungicidal action and can restrain slight infection by pathogens. Potassium contained in the microfertilizer ensures metabolic processes and thereby helps maintain plant turgor.
Magnesium is extremely important in plant metabolism. It promotes root system growth and transport of nutrients to plant organs. Magnesium is indispensable in photosynthesis, activation of most enzymes and energy conversion. The microfertilizer Ecoline Magnesium (Chelates) contains magnesium in chelate form and chelated forms of metal microelements that activate chlorophyll function.
Rapeseed is a boron-loving crop. Boron is a necessary element for its development throughout the whole growing season. In the early stages it strengthens the root system and keeps vascular bundles healthy. Using the special fertilizer Ecoline Boron (Premium) improves boron nutrition conditions and, thanks to the amino acids it contains, helps plants overcome stress.
Thus, to preserve the yield potential of winter rapeseed under the existing conditions, we recommend carrying out the first foliar feeding based on the actual condition of plants in a particular field:
- On poorly developed, heavily suppressed crops, in the first foliar feeding apply Ecoline Boron (Premium) 1.0 l/ha + Ecoline Phosphite (K) 1.0 l/ha
- With magnesium deficiency: Ecoline Phosphite (K) 1.0 l/ha + Ecoline Magnesium (Chelates) 1.0 l/ha.
- On normally developed crops: Ecoline Phosphite (K) 1.0 l/ha.
