The authors cited the results of comprehensive experiments on the application of innovative environmentally acceptable growth regulators on industrial crops: potatoes and soybeans. The experiments were conducted in 2019-2021 in the soil and climatic zone of the drained forest-steppe in the conditions of chernozem on potato varieties, Lyubava (early) and Tuleevsky (medium maturing), and soybean on grain Zolotistaya (early maturing).  These experimental fields belong to the Educational and Experimental Farm “Praktik” of Novosibirsk Region and the Closed Joint-Stock Company Livestock Breeding Farming “Irmen” of Novosibirsk Region. The maximum photosynthetic performance of Novosil and Ecofus applied to potatoes and soybeans is up to 19 % compared to control. The authors of the study treated crops before sowing as well as on the shoots before the beginning of the phase of budding. The yield against the growth regulators used increased significantly by 21-24 % when Novosil and Ecofus were applied during seed treatment and when spraying vegetative plants before the phase of budding. It was statistically established that the potato yield depended on variety by 30 %, on growth regulators by 33, and on conditions of the year by 23 %.

In the article, the authors presented the results of the experimental work (2019-2021) to study the application of differentiated fertilizer application on cereal crops. Western Siberia is a region with risky conditions for stable grain crop production. Soft spring wheat and spring barley are the primary crops for food and feed. Soft spring wheat and spring barley are also characterized by a high demand for the most important environmental factors, which are highly variable. Current trends in precision farming imply the need for different technological operations. These operations are differentiated both in time and by individual crop rotation fields. At the same time, operations take more fully into account the bio-resource potential of cultivated agricultural enterprises. And these operations also take into account soil and terrain features, which are controlled by the aggregates and their links to technological operations. In the field, the authors used aggregates with differentiated application rates of fertilizers or crop protection products. The yield mapping is an element of precision farming technology. This technology is achieved by signal sensors on combined and onboard computers and GPS receivers during the harvesting period. An accurate map of the field, showing the characteristics of each field section, enables rational resource allocation and increases yields from each section of the field. The availability of digital maps ensures the optimization of fertilizer, seed, and water application to each section of the field. Under the conditions of the JSC Livestock Breeding Farm Irmen, Ordynsiky district, Novosibirsk region, the data are entered into the on-board computer of agricultural equipment going into the field, and innovative control of technological processes in crop production is carried out through GPS navigation. The work aims to improve the technology of the application of differentiated fertilizers to grain crops in the precision agriculture system under forest-steppe conditions in the Novosibirsk region Priobye. The research was carried out in 2019-2021 in the soil and climatic zone of drained forest steppe on leached chernozem at JSC Livestock Breeding Farm «Irmen» on spring wheat varieties Novosibirskaya 31, Licamero, as well as the spring barley variety Paustian. The use of differentiated fertilizer application contributes to an increase in grain yield parameters of spring wheat by 36% and of spring barley varieties by 28%. The study showed that differential fertilizer application contributes to the improvement of grain quality parameters of soft spring wheat.

At present, it is of particular importance to further increase the yield and quality of grain crops under experimental conditions in Western Siberia. Of special meaning is finding new effective growth regulators and bio-fertilizers that promote ecological plasticity, resistance to environmental stressors and pests. The work aims to study the influence of the new biofertilizer Huminatrin on growth and development features, yield and quality of grain crops under conditions of increasing crop productivity in the northern forest-steppe of the Novosibirsk Priobye region. Experimental field was on the fields of JSC “Irmen” livestock breeding farm in Ordynsky district of Novosibirsk region. The authors determined that Huminatrin (a mixture of micronutrients and bacteria) provides an increase in leaf surface parameters in two varieties of wheat by 23% and in spring barley by 34%. The authors treated soil with Huminatrin before sowing in a dose of 2 l/t at operating-liquid flow rate of 10 l/t and during the growing season in the phases of tillering and earing in a dose of 1.5 l/ha (300 l/ha). It was shown that both wheat varieties and spring barley variety “Biom” significantly increased the yield on the background of Huminatrin. On average, the yield increased by 22%. When using Huminatrin, the authors observed an increase in the number of productive stems (up to 408 mg/m2), the number of grains in the ear (up to 32 pcs), weight of 1000 grains (up to 40.86 g). There was also an increase in gluten content - up to 34%; gluten deformation index was about 96. In addition, the authors note the reduction of plant infestation by brown rust to 28% against 47% in the control (water). Indicators such as weight of 1000 grains, weight of grains per plant, the number of grains in the ear form the quality of the crop. Application of Huminatrin allows to achieve high yield quality of two varieties: spring soft wheat and spring barley

The authors in the article provided data on the use of different varieties and hybrids of cereals and legumes. The experiments were carried out in the forest steppe of the Novosibirsk Priobya region in 2020–2022. The studies were conducted on the leached chernozem of the Praktik EEF (Educational and Experimental Farm) of the Novosibirsk Region and CJSC Livestock Breeding Farm Irmen of the Ordynsky District Novosibirsk Region. Also, the authors conducted experiments in the steppe zone on the southern chernozem of Nadezhda LLC of the Bagansky district and on grey forest medium loamy soil of the Education and Production Farm (EPF) “Garden of Michurintsev” in Novosibirsk. The research aims to study the efficiency of using the modern gene pool of grain and leguminous crops in different zones of Western Siberia. The authors found that West Siberian selection soybean varieties had higher growth and development rates than the Doka standard for 4-6 days. During studies with F1 hybrids of corn, the authors also note increased indicators of biometric parameters: plant height, green mass, and cob weight - by 20% of the Ross 140 F1 standard. High yield parameters of corn grain on the leached chernozem of the forest-steppe zone (EEF Praktik) of hybrids Ross 199 F1 - 10.2, KS-178 F1 and Krasnodar 194 F1 - 9.79 t/ha were revealed, exceeding the Ross 140 F1 standard by 40– 47%. Corn grains of hybrids F1 Ross 199 - 6.03 t/ha, Krasnodar 194 - 5.67 and KS-178 - 5.52 t/ha differed in yield with an excess of the standard by 54% on the southern chernozem of the steppe zone of Nadezhda LLC The maximum yield of corn grain is in the hybrid F1 Kuban 101 and Katerina - at 9 t/ha on the leached chernozem of CJSC Irmen stud farm. The maximum yield of soybean grain is 3.44 t/ha for SibNIIK-9 and Gorinskaya on leached chernozem, which is higher than the standard for Doka by 67 and 57%. SibNIIK-9, Omskaya 4, and Gorinskaya were distinguished on grey forest medium loamy soil. The variety of the Far Eastern selection Alena and the early ripening varieties of the RRIO collection (All-Russian Research Institute of Oilseeds, named after V. S. Pustovoit, Krasnodar): Barguzin, Lira, Sonata, and Puma, had a developed above-ground mass and low grain productivity. It was statistically determined that the genotype determined the yield of corn grain by 39%, conditions of the year - by 25%, and interaction of factors - by 20%. In experiments with soybean on leached and southern chernozem, the grain yield depended on the genotype by 42%, the conditions of the year - by 27% and the interaction of factors - by 16%, on grey forest medium loamy soil, respectively, 47; 30 and 22%.

The results of three-year research during 2019-2021 on the study of the effectiveness of precision farming elements in the forest-steppe of Western Siberia are presented. The experiments were carried out on leached chernozem at the Irmen breeding farm, Ordynsky district, Novosibirsk region. Elements of precision farming were tested on grain crops: spring wheat: varieties Likamero, Novosibirskaya 31 and Omskaya 36; spring barley varieties: Paustian and Margret and oats varieties Rovestnik. Navigation and drones of varying degrees of complexity were used, as well as a complex of differentiated fertilization. The aim of the work was to improve the technology of precision farming in the production of grain crops in the forest-steppe of Western Siberia. The effectiveness of the use of precision farming elements has been established. Due to the introduction of differentiated doses of mineral fertilizers, the grain yield of wheat varieties increased by 27%, spring barley 33% and oats - 23%. Against the background of the use of geolocation technologies in combination with differentiated application of mineral fertilizers, the yield level reached 7 t/ha for spring soft wheat of the Licamero variety, 8 t/ha for spring barley Paustian, and 5.6 t/ha for oats. In order to obtain a high yield of grain crops, doses of mineral fertilizers were applied differentially according to elementary fields up to 25 Oct. per 1 hectare and liquid nitrogen fertilizers up to 200 l/ha UAN-32, which ensured not only a yield of up to 7 t/ha, but also high technological quality of grain with a gluten level in spring soft wheat of the Licamero variety - 36%.
