The article describes the influence of different cultivation backgrounds on the yield structure and productivity in soft spring wheat of the zoned variety «Svirel» in the steppe of the Krasnoyarsk territory. It was found that the productive tillering and grains number in the ear from the crop structure elements in spring wheat variety «Svirel» had the best reaction to the using of fertilizers and chemical protection. The maximum average yield increase was observed when wheat was sown on a fertilized background with using of a full range of plant protection products, the minimum after previous grain without using of intensification agents.
