Influence of preparations of biochemical and microbiological origin on the yield of corn for grain on drip irrigation

The results of research on the study of the impact of agents of biochemical and microbiological origin of production LLP R&D Enterprise "5 Element" on the production process, the structure of yield and yield of corn under drip irrigation are highlighted. It is determined, that the highest yield of corn can be obtained by holding the pre-sowing treatment of seeds with nanobiostimulator of plant growth "V-Agro. Seeds" and the double treatment of vegetative plants with a solution of concentrate of products of vital activity of nitrogen-fixing soil algae. The combined use of the agent "V-Agro. Seeds" and the solution of concentrate of products of vital activity nitrogen-fixing soil algae provides a corn yield of 16,1 t/ha, which is by 5,5 t/ha, or 51,9 % more than in the absolute control (without seed treatment and foliar treatment of plants).  It is also established that the separate use of agents both for seed treatment and plant treatment during the growing season is also an effective measure. The single seed treatment with nanobiostimulator of plant growth "V-Agro. "Seeds" helps to increase the yield of corn by 1,6 t/ha, or by 15,1 %. A similar effect was obtained using for processing seeds of the biological product Soil Algae (live culture in powder form), where the increase in yield was 14,1 % (1,5 t/ha). It is determined that the use of agents for foliar application is more effective than pre-sowing seed treatment. The double spraying of corn plants, with respectively, 2 % and 4 % solution of concentrate of products of vital activity of nitrogen-fixing soil algae provides crop yields by 3,2 t/ha, or 30,2 % compared to the control. The use of nanobiostimulator of growth plants "V-Agro. Leaf processing" for foliar application provides the yield increase up to 2,8 t/ha, or 26,4 %. The biggest average weight of one cob corn was obtained due to the agricultural measure, which involves pre-sowing seed treatment nanobiostimulator of plant growth "V-Agro. Seeds" and the double treatment of vegetative plants with a solution of concentrate of  products of vital activity of nitrogen-fixing soil algae made it possible to get a cob with an average weight of 248,4 g, whereas in absolute control (without seed treatment and foliar treatment of plants) – 174,5 g.
