Environmentally Safe

Selenium plays an important antioxidant role in a living organism. At the same time, we often observe a deficit of selenium in natural environmental locations. Therefore, it is of great importance to elaborate and assess methods for the most efficient and environmentally safe intake of the necessary amount of this element in the human body with the consumption of vegetable food, among others. In this respect, the techniques of enriching plants with this microelement are promising. These techniques include additional introduction of selenium compounds into the soil and non-root intake. Our research consisted of an environmental assessment of the effect of selenium on biometric parameters, crop yield, and quality of spring wheat plants. Aziiev soft spring wheat, selenium microelement, meadow chernozemic soil were the objects of our study. It was determined that Se has a predominantly stimulating effect on the growth and development of wheat plants and their crop yield. A direct correlation between an increase in the applied doses of selenium and an increase in its content in wheat grain was identified. The results of our study can be applied for the development of appropriate methods for the use of selenium-containing micro fertilizers in certain environmental conditions.

The objective of this study was to analyze the effect of tillage systems and nitrogen fertilization on the grain yield and quality of spring wheat and on selected chemical and biological properties of soil. The first order factor was the tillage system: (1) conventional (CT) – shallow ploughing and harrowing after harvest of the previous crop, and pre-winter ploughing; (2) reduced (RT) – only a cultivator after harvest of the previous crop, and (3) no-tillage (NT) – only Roundup 360 SL herbicide (a.s. glyphosate) after harvest of the previous crop. The second order factor was nitrogen dose: (1) 90 kg N/ha and (2) 150 kg N/ha. Higher yields were demonstrated for spring wheat sown in CT and RT systems, compared to the NT system. In addition, grain yield was increased by a nitrogen dose of 150 kg/ha, compared to 90 kg/ha. Contents of protein and wet gluten in the grain were also increased by the higher nitrogen dose. The RT and NT systems were observed to increase the content of organic C, total N and available phosphorus in the soil, compared to the CT system. They also increased the number and mass of earthworms in the soil, compared to the CT system.

Исследования проводились на дерново-подзолистой среднесуглинистой почве. В опыте изучалось влияние систем удобрений на урожайность и качество яровой пшеницы. Объект исследования пшеница яровая Дарья. Установлено, что использование органо-минерального субстрата как отдельно, так и в сочетании с минеральными удобрениями (норма минеральных удобрений N80P80K80) способствовало повышению урожайности и улучшению качества зерна яровой пшеницы. По фактору систем удобрений наибольшая урожайность (23,08 ц/га) достигнута при использовании органо-минерального субстрата. В этом варианте урожайность повышалась на 11,77 ц/га в сравнении с контролем. Яровая пшеница сформировала достаточно высокую урожайность (20,17 ц/га) и при внесении минеральных удобрений в норме N80P80K80 в сочетании с органо-минеральным субстратом. В этом варианте урожайность была на 8,86 ц/га выше, чем в контроле. Наибольшее содержание белка (16,44 в пересчёте на абсолютно сухое вещество) и клейковины (39,34 на СВ) в зерне яровой пшеницы отмечалось при использовании органо-минерального субстрата совместно с минеральными удобрениями в норме N80P80K80, что важно для улучшения хлебопекарных свойств пшеничной муки.The researches were carried out on soddy podzolic medium loamy soil. In the trial the effect of fertilizer systems on the yield and quality of spring wheat was studied. The object of research is spring wheat Darya. It was established that the use of an organo-mineral support medium both separately and in combination with mineral fertilizers (the amount of mineral fertilizers N80P80K80) contributed to an increase in yield and an improvement in the quality of spring wheat grain. By the factor of fertilizer systems the highest yield (23.08 kg/ha) was achieved using an organo-mineral support medium. In this variant the yield was increased by 11.77 kg/ha in comparison with the control. Spring wheat has formed a sufficiently high yield (20.17 kg/ha) and when applying mineral fertilizers in the amount N80P80K80in combination with an organo-mineral support medium. In this variant the yield was 8.86 kg/ha higher than in the control one. The highest content of protein (16.44 in terms on absolutely dry basis) and gluten (39.34 in SV) in spring wheat grain was observed when using an organo-mineral support medium together with mineral fertilizers in the norm N80P80K80which is important for improving baking properties wheat flour.

The article is devoted to the study of the influence of chemical properties of the soil on the yield and quality of the grain of spring wheat. The highest yield of grain of spring wheat of Aquilon va-riety is observed at very high nitrification capacity of soil. As the amount of nitrate nitrogen in the soil increases, the protein content of the spring wheat grain increases. The higher the hydrolytic acidity of the soil, the lower the vitreousness of the spring wheat grain. As the sum of the soil ex-change bases increases, the nature of the egg wheat grain increases. As the yield of spring wheat grain increases, the weight of 1000 seeds and the gluten strain index decrease. As the percentage of weed impurity increases, the natural weight of the grain decreases. As the gluten content of the grain increased, the gluten strain index and the vitreous of the grain increased.

The article shows in 4 links of field rotation on the light-gray medium loamy soil effects of winter rye and lupine on the yield and quality of potato crop, spring wheat and aftereffects on the yield of third crops - barley and fifth crops - potatoes. Narrow-leaved lupine on gray forest soils of the Chuvash Republic in comparison with winter rye is the best precursor for spring wheat and potatoes. This provides not only the reliable increase of productivity of these crops, but also improve the quality of products. The starch fees per unit area also rises. It should be noted an increase of gluten content in grain of spring wheat from 20.2 % to 29.2 %. An aftereffect of narrow-leaved lupine was manifested at the third level cultures-barley and fifth-potato.

AbstractLarvae of the wheat stem sawfly, Cephas cinctus Nort, reduced the weight of grain per head by an average of 17.3% in the two spring wheats Red Bobs and Thatcher with annual reductions varying from 10.8% to 22.3%. They also lowered the protein content in Thatcher by an average of 0.6% and a maximum of 1.2%. However, because a significant loss in protein content occurred in only 1 of 6 years in Red Bobs, the effects of the larvae on protein content cannot be generalized for all varieties.The losses in weight per head resulted from a mean reduction of 11.9% in the weight of the kernels combined with a mean reduction of 1.9 in the number of kernels per head. The larvae caused the losses by feeding in the stems and by cutting them when the moisture contents of the kernels were relatively high. Annual variations in losses were attributed to the dates of the infestation, to the amount of precipitation in July and August, and to differences in dates of cutting by the larvae.
