Abstract
The article presents the results of field studies on the assessment of methods of presowing seeds treatment on different nutritional backgrounds. The experiments were conducted on the experimental field of Agrochemistry and Soil Science Department of Kazan State Agrarian University in 2015-2018 on gray forest medium loam granulometric composition of the soil with a humus content according to Tyurin 3.4%, absorbed bases 18.4 mmol/100 g, hydrolytic acidity 3.9 mmol/100 g, P2O5 and K2O according to Kirsanov, respectively 179 and 151 mg per kg soil, salt pH 5.6. Experiment design: Factor A - Presowing treatment of seeds: 1. VialTT- disinfectant (2 kg/t); 2. Extremely high frequency therapy - 15 minutes; 3. Extremely high frequency therapy - 30 min .; 4. Extremely high frequency therapy - 15 m. + VialTT; 5. Extremely high frequency therapy - 30 m. + VialTT. The options for pre-sowing seed treatment in the tables will be indicated by numbers from 1 to 5. Factor B - Nutrition backgrounds: 1. Without fertilizers; 2. NRK at 4.0 tons per hectare. The results of studies showed that the maximum accumulation of dry plant biomass (6.79 tons per hectare), an increase in leaf surface area (49 thousand m2 ha), high photosynthetic potential (3017 thousand m2 x day/ha), better control over the spread and development of root rot (P - 23%, R - 9.3%) and the maximum yield of winter rye grain (3.88 tons) from 1 ha occurred against the background with the introduction of mineral fertilizers calculated at 4.0 tons per hectare and application of electromagnetic processing “Extremely high frequency therapy - 30 min. + VialTT disinfectant - 0.5 litre per ton "for pre-sowing seed treatment.
