Optimization of the production of varieties of grain crops using a satellite navigation system in the forest-steppe of the Priobye region

The results of complex experiments on studying the effectiveness of the use of geoinformation technologies on grain crops of CJSC breeding farm "Irmen" of the Ordynsky district of the Novosibirsk region, which is part of the drained forest-steppe of Western Siberia, are presented. Varieties of soft spring wheat, spring barley and oats place increased demands on environmental factors and are characterized by high variability. The use and implementation of modern satellite navigation systems makes it possible to increase the yield and quality of the main grain crops in the zone of risky farming in Western Siberia. The purpose of the research is based on optimizing the technology of growing grain crops using a satellite navigation system in the forest-steppe of Western Siberia. The studies were carried out in 2029-2022. in the soil-climatic zone of drained forest-steppe, which is part of the northern forest-steppe of the foothills of the Ob. The soil of the experimental plots is leached chernozem with a humus content of 6.18%, gross nitrogen - 0.34, phosphorus - 0.22 and potassium - 1.23%. The content of easily hydrolysable nitrogen is 10.8, mobile phosphorus 21.9 and exchangeable potassium 19.8 mg/100 g of soil at pH 6.57. In the experiments we used a variety of spring soft wheat Likamero, spring barley Paustian and oat Rovesnik. The paper establishes regression equations between the yield and the sum of productive moisture reserves and precipitation in the interphase periods of different varieties of grain crops. Correlation parameters for each interphase period are marked. The dependence of the yield on the amount of precipitation for the interphase periods of grain crops was revealed. The role of geoinformation technologies in increasing the yield and quality of grain of spring wheat, spring barley and oats is determined.
