Tillage system and macronutrients are the many emerging farming issues that are addressed in contemporary cropping systems. In this regard, selection of a promising high-yielding variety of winter soft wheat was considered. The effects of basic tillage practices (Moldboard ploughing, Flat cutting ploughing and Disk ploughing) in combination with the different fertilization (Fertilizer-free, N90P50 and N180P100) were investigated on qualitative and quantitative parameters of winter wheat cultivar Grom under semi-arid environmental condition of southern Russia. The experimental design used in this experiment was a randomized complete block design (RCBD) with three replications. The highest winter wheat Grom yield with the value of 5.3 and 5.6 t/ha was attained for Moldboard ploughing and Flat cutting ploughing at a depth of 20-22 cm combined with application of nutrients N180P100, respectively. On the other hand, the lowest grain yield (2.78 t/ha) was achieved in fertilizer-free treatment in combination with Disk ploughing 12-14 cm depth. Moldboard ploughing plus nutrient application N180P100had the best results on leaf area (48.2 thousand m²/ha), photosynthetic potential (million m² x day/ha) and dry biomass (10.1 t/ha).

In terms of agricultural production, Western Siberia is a risky farming zone. Unfavourable weather phenomena in some years include moisture deficiency in the first half of the growing season, which negatively affects yield, as well as excessive moisture and lack of heat in the second half of the period, which leads to a decrease in grain quality. The special natural conditions of Siberia require specific consideration of the use of agricultural technologies that compensate for factors that negatively affect the yield of the land. The purpose of the presented study was to determine the most effective tillage options for increasing the yield of spring wheat in the Tyumen region (Russia). This study was conducted at the experimental field of the Northern Trans-Urals State Agrarian University from 2014-19 to evaluate the effect of basic tillage with and without the use of coulisse strips on the weed infestation and yield of spring wheat in the Tyumen region, Russia. Comparative evaluation of the basic tillage with or without sown coulisse strips showed less weed infestation of spring wheat (3.3-27.1 and 3.6- 29.4 no./m²) on the basic tillage variants (plowing and loosening) with sowing singleline coulisse strips, where the resulting larger yield of 3.74 t/ha (+ 0.17 t/ha compared to the control variant) was obtained. The results showed that moldboard tillage using coulisse strips had a positive effect on plant growth and development, due to the density, soil moisture, and weed reduction in obtaining high yield of spring wheat. The data obtained in the course of long-term studies can be used in the development of recommendations for agricultural production on the cultivation of spring wheat for grain and seeds under conditions close to those of the region under study.
