There is a great number of repeated and permanent spring wheat crops with insufficient areas occupied by forecrops of the first group in the grain-sowing zones of the Omsk region, which leads to a decrease of soil fertility, productivity and grain quality. The aim of the research is to reveal the influence of rapeseed forecrop on fertility, phytosanitary state of agrophytocenosis, productivity and technological properties of spring wheat grain in the forest-steppe of Western Siberia. Complex studies were carried out in a stationary crop rotation of Omsk Agrarian Scientific Center (rapeseed-wheat-soybean-wheat) in 2011-2017. The effectiveness of different intensity impact of soil cultivation systems in crop rotation and effectiveness of intensification means were studied in a two-factor experiment on meadow-black soil. The influence patterns of agricultural technologies on soil fertility elements, phytosanitary state of agrophytocenosis, productivity and technological parameters of grain were established. It was found that in case of intensity decrease of soil cultivation systems in a crop rotation, especially with limited application of intensification means, there is a spring wheat yield decrease after rapeseed forecrop by 0.17 t / ha. Grain yield increases to 2.88 t / ha in case of complex usage of chemicals, with a decrease of variability over years (variation coefficient) from 55 to 37% or by 1.5 times. The application of fungicides reduces the development and prevalence of infections on the upper layer of leaves and increases yield by 0.56 t / ha or by 27.5%. An increase of the mass of 1000 grains, the nature of grain, the content of protein and gluten was observed on the variant of intensive cultivation technology.

“…Natural factors have a significant impact on the growth and development of corn plants and the level of its productivity [4,5,6]. Thus, in the subzone of unstable moistening of the left-bank foreststeppe of Ukraine, a higher correlation was observed between climatic indicators and productivity during the critical growing season of corn [7].…”

The article considers the factors influencing the stability of agrocenoses of corn hybrids in the forest-steppe zone of the Krasnoyarsk Territory. The researches were carried out for three years in the zone of sharply continental climate of the Krasnoyarsk forest-steppe on leached low- and medium-thick chernozems. The main factors influencing the stability of agrocenoses of corn hybrids were determined. So the factor of climatic conditions affects the corn hybrids, its influence is no more than 14%. The factor of pre-sowing preparation and the precursor (cereals and fallow) showed not significant effect, no more than 2%, on the formation of agrocenoses of corn hybrids. Thus, the factor genotype of the hybrid was fundamental in determining its significance for agrocenoses. The main biometric factor that determines the productivity of corn hybrids was also identified. Correlation analysis made it possible to reveal the influence of the average plant height on the productivity index of corn, as well as on the ear weight. But at the same time, it was determined that the mass of corn ears decreases with an increase in the average height, in the structure of the crop agrocenoses of corn hybrids.

“…However, this effort may be limited by certain problems such as environmental conditions and economic factors [32,33]. As stated by many researchers, in the conventional tillage and conservation tillage systems, the yield and quality parameters of crops are functions of the interactions of many parameters, which are difficult to predict [34][35][36]. Generally, from the review of the results of research studies conducted in this paper, it can be stated that when reducing the levels of tillage from the conventional system to conservation tillage systems (RT or NT systems) in cereals, there is a decrease in crop yield [37].…”

In this study, we aimed to determine the effects of tillage systems (TS) on wheat grain yield, yield components, and physicochemical properties under rain-fed conditions over 2 years (2018–2019) in the Kuhdasht region in southwestern Iran. The tillage treatments were a combination of conventional tillage (CT), reduced tillage (RT), and no tillage (NT) systems based on randomized complete blocks with three replications. Wheat grain yields and yield components, physical properties (geometrical dimensions, sphericity, thousand-grain mass (TGM), water absorption (WA), volume (V), and density), chemical composition (protein content (PC), water content (WC), fiber content (FC), ash content (AC)), surface color parameters (L*, a*, and b*), and correlations among measured parameters were assessed. The results showed that wheat grain yield and yield components were significantly affected by TS (p < 0.01). The wheat grain yield was higher under CT (2.72 t ha−1), with a significant difference between RT (1.76 t ha−1) and NT (1.20 t ha−1). The highest TGM (49.19 g) was achieved under CT, followed by RT (43.41 g), with the lowest (39.17 g) in the NT system. TS had significant effects on certain physical properties of wheat grains (p < 0.01). Wheat grain, size, shape, and mass values were higher under CT than RT and NT systems in all experimental years. CT resulted in the highest WA, while the lowest resulted from NT. TS had no significant influence on the density of the grains. TS had significant effects on PC, AC, and WC values of grains at the 1% probability level and on FC at the 5% level. Higher PC values were obtained under the CT system (13.07%, against 11.90% and 10.67% for RT and NT, respectively) in all growing seasons. Additionally, the AC was significantly lower in the sample grains under RT (2.38%) and NT (2.43%) than in those from CT (2.56). The FC was higher under NT (15.73%) than RT (13.73) and CT (13.71%). The grain WC was significantly higher under NT (7.57%) than RT (6.79%) and CT (7.0%). The TS significantly affected the surface color parameters of grains, while the L* (lightness) and b* (yellowness) values of grains under CT were higher than in RT and NT.
