Многолетний стационарный полевой опыт проводился на дерново-подзолистой среднесуглинистой почве в Ярославской области. В статье представлены результаты исследований по изучению действия разных по интенсивности систем обработки почвы и удобрений на изменение агрохимических показателей плодородия почвы и урожайности яровой пшеницы. Отмечена динамика накопления гумуса в пахотном слое почвы при системе поверхностно-отвальной обработки на 0,17%, совместном внесении соломы и полного минерального удобрения – на 0,15%. Выявлен рост рН при системе ежегодной отвальной обработки, системах без удобрений и одной соломы. Динамике повышения содержания фосфора на 57,00 мг/кг способствовало совместное применение соломы с полным минеральным удобрением. Увеличению содержания обменного калия содействовали: система энергосберегающей поверхностно-отвальной обработки (на 0,92 мг/кг) и система «солома + NРК» (на 44,09 мг/кг). Отмечено увеличение урожайности зерна яровой пшеницы (на 2,04 ц/га) при применении системы энергосберегающей поверхностно-отвальной обработки почвы. Совместное использование соломы с полным минеральным удобрением достоверно повысило урожайность на 8,18 ц/га. Для дерново-подзолистой среднесуглинистой почвы с временным избыточным увлажнением рекомендуется применение системы энергосберегающей поверхностно-отвальной обработки почвы и совместное внесение соломы с полным минеральным удобрением. Long-term stationary field experiment was carried out on soddy podzolic middle loamy soil in the Yaroslavl region. The article presents the results of research on the effect of soil and fertilizer treatment systems different in intensity on changing agrochemical indicators of soil fertility and spring wheat yield. Dynamics of humus accumulation in arable layer of soil at system of surface and moldboard tillage by 0.17%, combined application of straw and complete minerals - by 0.15% was noted. An increase in pH was revealed with an annual moldboard tillage system, systems without fertilizers and straw. The dynamics of the increase in phosphorus content by 57.00 mg/kg were facilitated by the joint use of straw with complete minerals. The increase in the content of exchangeable potassium was facilitated by: an energy-saving surface and moldboard tillage (by 0.92 mg/kg) and a "straw + NPK" system (by 44.09 mg/kg). There was an increase in the yield of spring wheat grains (by 2.04 c/ha) when using an energy-saving surface and moldboard tillage system. The combined use of straw with complete minerals significantly increased yield by 8.18 c/ha. For soddy podzolic middle loamy soil with temporary excessive moistening it is recommended to use a system of energy-saving surface and moldboard tillage and joint application of straw with complete minerals.

Triallate granules were applied at 2.8 kg/ha without incorporation either immediately before or after planting into standing spring wheat (Triticum aestivum L. ’Fielder’ and ’Dirkwin’) stubble. The triallate granules controlled wild oat (Avena fatua L.), and resulted in increased spring wheat yield. Difenzoquat or diclofop-methyl application also increased wheat yields.Key words: Triallate, oat (wild), conservation tillage, minimum tillage, wheat (spring)

Agronomic practices, such as planting date, seeding rate, and genotype, commonly influence hard red spring wheat (HRSW, Triticum aestivum L. emend. Thell.) production. Determining the agronomic optimum seeding rate (AOSR) of newly developed hybrids is needed as they respond to seeding rates differently from inbred cultivars. The objectives of this research were to determine the AOSR of new HRSW hybrids, how seeding rate alters their various yield components, and whether hybrids offer increased end-use quality, compared to conventional cultivars. The performance of two cultivars (inbreds) and five hybrids was evaluated in nine North Dakota environments at five seeding rates in 2019−2020. Responses to seeding rate for yield and protein yield differed among the genotypes. The AOSR ranged from 3.60 to 5.19 million seeds ha−1 and 2.22 to 3.89 million seeds ha−1 for yield and protein yield, respectively. The average AOSR for yield for the hybrids was similar to that of conventional cultivars. However, the maximum protein yield of the hybrids was achieved at 0.50 million seeds ha−1 less than that of the cultivars tested. The yield component that explained the greatest proportion of differences in yield as seeding rates varied was kernels spike−1 (r = 0.17 to 0.43). The end-use quality of the hybrids tested was not superior to that of the conventional cultivars, indicating that yield will likely be the determinant of the economic feasibility of any future released hybrids.

Properly selected tillage methods and management of the available organic matter resources are considered important measures to enable farming in accordance with the principles of sustainable agriculture. Depending on the depth and intensity of cultivation, tillage practices affect soil chemical composition, structure and biological activity. The three-year experiment was performed on the soil under spring wheat (cv. Tybalt) short-time cultivation. The influence of different tillage systems and stubble management on the soil’s chemical and biological parameters was analyzed. Organic carbon content (OC); content of biologically available phosphorus (Pa), potassium (Ka), and magnesium (Mg); content of total nitrogen (TN), mineral nitrogen forms: N-NO3 and N-NH4 were determined in various soil samples. Moreover, the total number of microorganisms (TNM), bacteria (B), actinobacteria (A), fungi (F); soil respiratory activity (SR); and pH in 1 M KCl (pH) were also investigated. The results show that organic matter amendment is of greater influence on soil characteristics than the tillage system applied. Manure application, as well as leaving the straw in the field, resulted in higher amounts of organic carbon and biologically available potassium. A significant increase in the number of soil microorganisms was also observed in soil samples from the experimental plots including this procedure.

The research has been carried out under production conditions on light gray forest soils with light particle-size composition at an area of 550 hectares where liquid pig manure (LPM) of a large pig breeding complex is annually used as an organic fertilizer at doses of 60 and 90 t/ha. The average characteristics of LPM are as follows: dry matter content is 9.5%, pH 7.7 units, nitrogen 0.22%, phosphorus 0.11%, and potassium 0.12%. The cultivated grain crops were presented by winter and spring wheat varieties, Moskovskaya 39 and Esther, respectively. It has been established that at the dose of 60 t/ha LPM for two years of research at an average a mean wheat yield was 3.0-3.75 t/ha, and at the dose of 90 t/ha - up to 4.75 t/ha. The return on investments for fertilizers in the “winter wheat → spring wheat” crop rotation link at the dose of 60 t/ha of LPM was 5.41 kg of grain per 1 kg of active substance of manure, at the dose of 90 t/ha - 4.57 kg / kg. A positive balance of nutritional elements developed on all fields, but it was better balanced when the dose of LPM was 60 t/ha and the yield was 3.0 t/ha of grain annually, or when the LPM dose was 90 t/ha and the yield of wheat was 4.75 t/ha. In this case, the estimated potassi-um supply of soil occurs at a lower rate than that of nitrogen and phosphorus. The application of 120 t of LPM during two years in total on loamy sand and of 180 t/ha on light loamy soil provided an increase in the content of mobile phosphorus compounds by 5-22 mg/kg, and potassium - by 11-30 mg/kg with a variation coefficient of 28-57% and 21-49%, respectively.

Abstract To study the effect of sodium Selenite application different methods on the yield of spring wheat varieties, depending on the conditions of water supply, a series of vegetation experiments in accordance with the methodology were carried out. The object of the study is spring wheat of the Zlata variety (Triticum aestivum L.). It was found that the effect of selenium on the yield of wheat of the Zlata variety depended on the method of its application and the conditions of water supply. With optimal water supply, the positive effect of selenium on the yield of spring wheat plants was revealed with both methods of applying sodium selenite. It was found that in conditions of drought, the positive effect of selenium was obtained with both methods of using sodium selenite. The greatest efficiency of selenium is obtained in foliar processing of plants. The increase in grain weight in this variant was 1.4 times. The increase in the share of the agronomic significant part of the wheat crop yield to 36% is shown, which indicates the decrease in the negative effect of drought on the formation of spring wheat yield when using foliar processing of plants.
