Abstract

The results of the study of the influence of organic fertilizers produced on the basis of the latest technologies on the biometric indices and productivity of maize plants of the hybrid Liubava are given. It was established that the introduction of organic fertilizers “Bioproperments” at a dose of 10 t/ha under the basic cultivation of soil and liquid organic fertilizer "Biohrom" at a dose of 5 l/ha during vegetation of corn plants contributes to an increase in the number of plants during full ladders at 5716 pcs. ha for field similarity 86,6 %; height of plants in the flowering phase of 27 cm; the leaf area of corn plants at 7,68 thousand m2 / ha and the increase in corn yield at 2.72 tons/ha compared to control.The results of the research showed that the plant density after full stairs in the version of the introduction of “Bioproperty”, 10 t/ha + Biohrom, 5 l/ha was 5716 pc./ha more compared to control and 716 pc./ha more compared with the option of introducing Bioactive, 10 t/ha + Biohrom, 5 l/ha. In the variant of introduction of N120P80K80 + “Biohrom”, 5 l/ha of plant density was 109 pc/ha more compared to the option without "Biohrom"The area of the leafy surface in the flowering phase in the variant of introduction of “Bioproperments”, 10 t/ha + “Biohrom”, 5 l/ha was 7,68 thousand m2/ha more in comparison with the control and 1,11 thousand m2/ha higher compared to the bioavailing option, 10 t/ha + “Biohrom”, 5 l/ha. In the variant of introduction of N120P80K80 + “Biohrom”, 5 liters per hectare of leaf area of plants was 0,55 thousand m2/ha more compared to the option without “Biohrom”.The yields in the variant of introduction of “Bioproperty”, 10 t/ha + “Biohrom”, 5 l/ha was 2,72 t/ha more in comparison with the control and 0,83 t/ha more compared to the option “Bioactive” 10 t/ha + “Biohrom”, 5 l/ha. In the variant of introduction of N120P80K80 + “Biohrom”, 5 l/ha yield was 0,73 t/ha more, compared with the option without Biohrom.Consequently, trivalent chromium present in Organic Fertilizers Bioproferm and Biohrom positively affects the growth and development of maize plants and increases the yield of crops.
