Soil Weight

Exceeding the background lead content in ordinary chernozem by 25 mg/kg, and the oil content of 0.25% of soil weight, cannot be considered environmentally safe. These doses cause significant impairment of growth and development of winter wheat. Moreover, lead enters grain and straw in large amounts.

Abstract. Purpose of the study: to study the effect of oil pollution on the morphological parameters of cereal grasses: canary grass, timothy grass and meadow fescue. Tasks: assessment of the impact of oil pollution of soils on seed germination, growth and development of the studied species by morphological parameters; analysis of the species variability of the studied indicators. Oil-contaminated high-moor peat was used as a substrate. Objects of research: seeds of cereal grasses: meadow timothy Phleum pratense L, 1753, meadow fescue Festuca pratensis Huds, canary grass Phalaris canariensis. Evaluation of the effect of oil-contaminated soil was carried out on the basis of changes in seed germination and morphological parameters: plant mass, leaf length, length and number of roots. The experimental results were processed by the method of variation statistics. As a result of studying the effect of oil-contaminated peat on seed germination, it was found that in the variants of the experiment with the minimum oil content, no differences were noted with the control values. The maximum concentration of oil (10,000 mg / kg) reduced seed germination by 924%. With an increase in the oil content in the soil, the morphometric parameters of all the studied species of cereal grasses also decreased. The greatest differences in the studied test functions, in comparison with the control variant, were noted in canary grass, the smallest in meadow fescue.

In this study, mints were regenerated from calluses irradiated by γ - rays (Co-60) at doses from 0 to 70 Gy. After 4 times of propagation, the M1V4 mints were transferred in a greenhouse for assessments of growth, development and essential oil content. Mint regenerated from calluses irradiated at low doses (0, 3, 4, 6, 8 and 10 Gy) showed no morphological difference compared to the control plants. However, low-dose irradiated mints showed better effect on growth and development, and mints regenerated from 6Gy-irradiated sample had essential oil content with 1.3 times higher than that of control group. In case of plants irradiated at higher dose (30, 40, 50, 60 and 70 Gy), there were morphological variations such as stem become bigger and color of stem become purple. Especially, samples irradiated at 60 Gy showed better in growth, development and essential oil content (1.34 times higher than the control plants) and these characters were stable in M1V4. Among the irradiated mints, purple stem variations had the highest essential oil yield with 1.7 times higher than that of the original plants.

The research was carried out in order to study the effect of the use of biological preparations and micronutrients (separately and in combination with each other) on the growth and development of winter wheat grown according to the sunflower precursor in the zone of unstable moisture. The experience was laid in 2020-2021 on leached chernozem. Two factors were studied in the experiment: drugs and the timing of their use. The classical technology of winter wheat cultivation adopted for the zone was used as a control. The scheme of the experiment included options with the use of biological preparations, micro-fertilizers separately and in combination with each other when etching seeds and during the growing season of winter wheat. The combined use of biological preparations and micronutrients provides an increase in yield by 10.2%, whereas with a separate application the increase was 4.5-5.7%.

Fertilizer System

Through the period of 1977–2018, studies were conducted on three experimental fields of the Samara State Agricultural Academy with the purpose of studying the influence of the basic elements of the farming system on the weediness and the yield of winter wheat. Experimental schemes included the following options: the type of fallow in the crop rotation (black, seeded and green-manured), fertilizer systems (organic-mineral recommended, organic-mineral intensive and organic) and various methods and depths of soil tillage of fallow lands. Observations and surveys were carried out according to generally accepted methods. The soil of the plots was ordinary chernozem and typical medium-thick loamy chernozem (humus content was from 6.0 to 8.3 %, mobile phosphorus was from 90 to 155 mg/kg, exchange potassium was from 129 to 190 mg/kg, pHsalt was from 6.3 to 6.8). Replacing black fallow with seeded or green-manured fallow increased the weediness of crops 1.4–1.6 times and reduces the yield of winter wheat by 0.29–1.03 t/ha. Organic fertilizer systems significantly changed the weed species compositions and contributed to an increase in the number of perennials by a factor of 3.0, and their masses by a factor of 1.3–1.4 in comparison with organic-mineral fertilizer system. Organic-mineral fertilizer systems did not have a significant effect on the yield of winter wheat. The organic fertilizer system led to a slight (0.26–0.31 t/ha) grain shortage compared with organic-mineral. The methods and depths of soil tillage did not have a practically significant effect on the weediness and yield of winter wheat.
