Application on onion

Treatment of seeds (planting material) with the formulation for planting material treatment VIMPEL®-K (2-3% solution) with stimulant properties and complex micronutrient ORAKUL® seeds (5% solution) results in:

  • increase of germination rate up to 5%, field germination of seeds up to 6% and seedling growth energy, which makes it possible to generate a given stand density of plants;
  • enhancing of active development of root system and sprouts;
  • enhancing of the secondary root system formation resulting in increase of drought resistance by 25-30%;
  • increase of photosynthetic productivity by 6%.

Application of plant growth stimulator VIMPEL® in the phase of 5-6 leaves and in the period of active growth (application rate 500 g/ha):

  • accelerates the metabolic processes in tissues, plants absorb more intensively food compounds from the soil and from micronutrients when applying foliar feeding, fertilizing effectiveness is increased by 30%;
  • eliminates in tank mix with herbicide phytotoxic effects of the latter and rapidly relieves plant from stress, which is evident through the intense leaf formation;
  • enhances the efficacy of pesticides by 20-25%;
  • improves photosynthetic activity due to the increase of chlorophyll content in leaves;
  • decreases by 2 – 2.5 times disease development intensity;
  • activates development of soil microorganisms by 1.5 – 2 times; 
  • enhances heat and drought resistance of plants;
  • increases bulb size by 15%;
  • increases productivity, marketability, quality and storability of bulbs.

Adding of the complex universal micronutrient ORAKUL® multicomplex (application rate1.0-2.0 L/ha) at this time provides the plant with all the necessary nutrients, regardless of changes in weather conditions or the physiological state of the soil. Besides due to it:

  • plant height is increased;
  • solids content is increased;
  • bulb weight is increased, as well as productivity. 

Application of  micronutrient ORAKUL® sulfur active 1.0-3.0 L/ha is determined by an increased demand of onion in sulfur. Its deficiency leads to chlorophyll destruction; leaves acquire bleak, yellowish color, decrease of plant disease resistance. 

Application of micronutrients ORAKUL® (
В, Fe, Cu, Zn, Mn, Mo, Mg) is conducted when there is deficiency of the corresponding elements.

Combined application of VIMPEL® and VIMPEL®-K growth stimulators with micronutrients from ORAKUL® series in cultivation technology of onion (seed (planting material) treatment), then plant treatment in the phases of 5 – 6 leaves and active growth) leads to the highest economic return. Yield increase is from 5 to 8.8 t/ha with improved marketable quality of bulbs.
