Innovative aspects of stimulating the growth and development of grain and leguminous crops in Western Siberia

The results of three-year studies (2020-2022) on the effectiveness of pre-sowing seed treatment of grain crops (spring soft wheat, spring barley and oats) and legumes (soybeans) in terms of stimulating growth and development, increasing productivity and product quality are presented. The experiments were carried out on leached chernozem and gray forest soil of the Novosibirsk and Orda districts of the Novosibirsk region. In the experiments, we used the variety of spring soft wheat Likamero, spring barley Paustian, oats - Max and soybeans - SibNIIK 9. The largest leaf area parameters were noted in spring wheat against the background of presowing seed treatment with Lignohumate 80 g/t, followed by spraying in the tillering phase with Energia M 20 g/ha. The applied growth regulators significantly increased the yield of grain crops and soybeans. The highest yield was established in the variants with seed treatment with Lingvohumate followed by the use of Energia M in the tillering phase. The increase was 21% for spring wheat, 23% for barley and 24% for soybeans. The preparations used improved the yield structure of all crops.
