Іnfluence of biopreparations on indicators of sowing qualities and productive properties of winter rye seeds

The results of the research of the impact of the introduction of biologicals Biocomplex-BTU and Organic-balance on seed productivity and yield properties of winter rye varieties Siverske and Intensive 99 were presented in the article. The aim of the research was to determine the impact of biologicals on seed productivity, sowing qualities and yield properties of winter rye seeds in the conditions of the Forest-Steppe of Ukraine. According to the results of the research, the combination of pre-sowing seed treatment and double spraying of crops: in the phases of spring tillering (III e.o.) and plant emergence in the tube (IV e.o.) increases seed productivity by 3.1–11.5%. It is determined that pre-sowing seed treatment provides an increase in sowing qualities of seeds (germination energy, laboratory germination) by an average of 2.8-3.8 %. It is recommended in the Forest-Steppe conditions for farms growing basic (elite) seeds of winter rye to use biological products Biocomplex-BTU or Organic-Balance in a complex way, namely: pre-sowing seed treatment (2.0 and 1.5 l / t) and double spraying of crops in the phases of spring tillering (0.8 and 0.5 l / ha) and the release of plants into the tube (0.8 and 0.5 l / ha, respectively). This provides an increase in grain and seeds in winter rye varieties by an average of 0.42 and 0.36 t / ha, depending on the biological product.
