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.

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.

Foliar Treatment

The purpose of the article was to study the resistance of spring wheat under the influence of foliar treatment of plants with silicate bacteria according to lipid peroxidation (LP) and yield. The studies were conducted on spring wheat (variety ‘MiS’). The cultivation technology is typical wheat in this agroclimatic zone. The foliar treatment was carried out with a culture of bacteria Bacillus oligonitrophilus by spraying at the rate of 0.5 l/m2 of bacteria suspension containing 109 cells/ml (equally to 100% concentration). Field experiment design: option 1 – plants without treatment (control); option 2 – treatment with B. oligonitrophilus fertilizers at the stage of tillering; option 3 – treatment with B. oligonitrophilus fertilizers at the stage of tillering/stem elongation; option 4 – treatment with B. oligonitrophilus at the stage of tillering/stem elongation/heading. The activity of LP in wheat leaves was identified according to the content of malondialdehyde (MDA). The content of MDA was determined photometrically during interaction with thiobarbiturate. Wheat yield increase was observed in options 3 and 4 (by 11 and 15%, respectively). The content of MDA decreased in all phases of wheat vegetation in the same experimental options (by 14 and 21%, respectively), which indicated the antioxidant effect of the studied preparation. Thus, the bacterization of wheat with B. oligonitrophilus leads to the plant resistance increase. The protective effect is probably due to the action of a complex of their biologically active substances (metabolites) including the antioxidant mechanism of action.

The research of the biological preparation Fertenat effect on spring wheat was investigated at the Experimental Station of Aleksandras Stulginskis University in Calc(ar)i-Epihypogleyic Luvisol (LVG-pw-cc) during 2013–2014. Spring wheat was grown according to the requirements of the National Agricultural Products Quality System. Biological preparation Fertenat had a significant effect on the elements of spring wheat yield structure and the values of chemical composition parameters, influenced by the rates of biological preparation and meteorological conditions. A strong correlation was found between the Fertenat rates and spring wheat plant stem and ear length, grain number per ear, total and productive stem number of one plant and 1 000 grain and hectolitre weight. The correlation between the biological preparation rates and protein, wet and dry gluten was strong as well. A strong correlation between the biological preparation rates and starch amount in grain was found in 2013, while in 2014 this correlation was moderate. The application of biological preparation Fertenat increased the spring wheat yield by 0.05–0.30 t ha–1 or by 2.29–13.76 percent units and by 0.02–0.41 t ha–1 or 0.40–8.23 percent units. The application of 6 l ha–1 and higher Fertenat rates significantly increased the spring wheat yield. Small 1–3 l ha–1 rates are inefficient. The correlation between the Fertenat rates and grain productivity was strong.
