Application on sunflower
 
Application of the plant growth stimulator VIMPEL® (application rate 0.5 L/t) as a formulation for planting material treatment and complex micronutrient fertilizer LURS® Hit (application rate 1.0 – 1.5 L/t) results in:
  • increases the germination energy and field germination rate up to 5%, which makes it possible to generate a given stand density of plants;
  • enhances the active development of root system, thus increasing drought resistance by 20-25%;
  • increases vegetative mass of plants and leaf surface area by 16-32%;
  • increases effectiveness of photosynthesis.

Application of the plant growth stimulator VIMPEL® in the phases from 2 true leaves till flowering (application rate 0.5 L/ha):
  • accelerates the metabolic processes in tissues, plants absorb more intensively food compounds from the soil and from micronutrient fertilizers when applying foliar feeding, fertilizing effectiveness is increased by 30%;
  • protects plants against pesticide stress in the case of both soil-applied and postemergent herbicides, plants acquire a distinctive green color and proceed growing as soon as in 2 days after the treatment;
  • increases leaf surface area;
  • increases chlorophyll content, resulting in an increase of photosynthetic efficiency;
  • decreases water-consumption ratio, plants use moisture more sparingly;
  • increases drought and heat resistance;
  • increases productivity.
Adding of the complex universal micronutrient fertilizer LURS® multikompleks (application rate 1.0-2.0 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:
  • diameter of anthodium increases;
  • weight of 1000 seeds increases.
Application of the micronutrient fertilizer LURS® colofermin boron (application rate 1.0-1.5 L/ha) is determined by increased demand of sunflower in boron. When there is a lack of it, plant growth is inhibited, number of flowers is decreased and fertilization is disordered. Combined application with LURS® multikompleks in the phase of 2nd – 4th pair of true leaves leads to the increased productivity up to 360 kg/ha, in the case of adding VIMPEL® – up to 540 kg/ha.

Application of the micronutrient fertilizers LURS® (S, Fe, Zn, Cu, Mn, Mg) is conducted when there is deficiency of the corresponding elements.

According to the data of the leading research institutions::
  • seed pretreatment VIMPEL® + LURS® Hit and treatment in the phase of 2nd – 4th pair of true leaves with VIMPEL® + LURS® multikompleks + LURS® colofermin boron and additional treatment in the phase of 6th – 8th pair of leaves with VIMPEL® + LURS®multikompleks + LURS® colofermin boron increases productivity by 730 kg/ha.
Combined application of stimulators and micronutrient fertilizers by DOLINA company is an economically justified measure. Those agricultural enterprises, which implemented these formulations into sunflower cultivation technology, will get extra yield from 290 to 730 kg/ha.
