In the arid forest-steppe soil–climatic zone of Western Siberia in the grain–steam crop rotation (steam – wheat – peas - wheat - barley), the influence of agricultural technologies of spring wheat after the pea forecrop on field germination of seeds, water consumption, nutrient regime, contamination, infection of agrophytocenosis, productivity and grain quality has been established. Intensive agrotechnology, with the complex use of fertilizers, herbicides, fungicides, increased the yield of high–quality grain from 1.93 to 3.79 t/ha with the advantage of resource-saving flat-cut tillage - 3.95 t/ha. Yield increases in increasing sequence are placed in the following order: biostim (0.22 t/ha – 9%), insecticides (0.31 – 13%), fungicides (0.49-21%), herbicides (0.50 – 21%), fertilizers (0.87-36%), combined use of fertilizers and herbicides – 1.37 tons/ha. The specific weight of leguminous crops in the zonal structure of arable land should be expanded to 6-8%.
