PARTICULAR QUALITIES OF THE INFLUENCE OF PRE-SOWING SEEDS OZONIZATION ON YIELD INCREASING AND QUALITY INDICATORS OF SPRING WHEAT GRAIN
Ozone treatment is an environmentally friendly operation that does not pollute the environment, unlike chemicals used in agriculture today. It was found that the use of the process of pre-sowing ozonation of seeds improves such indicators as germination energy, germination, growth strength, bushiness of plants, resistance to diseases, pests and fungal infections, and also increases the yield of agricultural crops. The article presents the results of studies on the influence of pre-sowing ozonation of seeds on the yield and grain quality indicators of spring wheat of the Ester variety in the conditions of the Kostroma region. The research was carried out on the experimental field of the A.G. Lorkha "- Kostroma Research Institute of Agriculture in the period from 2015 to 2018. Studied the concentration of ozone 1.5 (option - Ozone-1) and 2.8 mg / m3 (option - Ozone-2). The processing (exposure) time was the same - 20 minutes. It was found that ozonation of seeds before sowing affects the increase in grain yield by 0.14-0.58 t / ha (7.8-22.7%), the weight of 1000 seeds - by 1.4-1.9 g, harvest crude protein - by 41-50 kg / ha. Of the studied pre-sowing ozonation modes, the most effective is seeds treatment with an ozone concentration of 1.5 mg / m3 with an exposure time of 20 minutes. Due to the greater length of the spike, the mass of grain and its quantity in the spike increased, which had an effect on increasing productivity. Ozonation of seed is a promising technique for increasing the yield and grain quality.
