Evaluation of the effect of new organomineral preparations on yield formation and grain quality of winter wheat

DOI 10.24411/1029-2551-2020-10014

In recent years, the state catalog of pesticides and agrochemicals approved for use in the territory of the Russian Federation has been supplemented with new drugs that represent a whole complex of various compounds containing macro- and microelements, amino acids, polysaccharides and other biologically active substances. The mechanism of their action on the plant organism is not sufficiently covered in the literature. Therefore, it is necessary to study the production process of winter wheat plants when using this kind of drugs to study the features of this process, and develop scientifically based recommendations for their use. In this study in the Stavropol region in 2015-2017, it was found that the use of new preparations in winter wheat cultivation technology increases the yield of winter wheat by an average of 4.2-6.9 с/ha, improves the quality of grain, which is manifested in an increase in the protein content by 0.1-0.8% and the amount of raw gluten by 1.0-3.6%, as well as an increase in the chlorophyll photosynthetic potential of winter wheat crops by 1-15%. Treatment with the tested preparations increased the photosynthetic efficiency of crops (the value of net productivity is 25.7% higher than the control value). Preparations Atlante Plus and Nutrivant Grain contributed to improving the conditions of nitrogen nutrition of winter wheat, as can be seen by maintaining the activity of the enzyme nitrate reductase in the reproductive period (exceeding the control is 51.6-79.0%) and increasing the nitrogen content in plants by 64.8-102.2%.

Content of humus and total nitrogen in the forest-steppe soils and dose of the nitrogen fertilizers under the planned yield of spring wheat

DOI 10.24411/1029-2551-2020-10016

The statistical average humus content was calculated from the definitions of large-scale soil studies. From soddypodzolic to chernozems typical arable horizon of zonal soils contains 73.0-257.7; the half-meter thickness is 93.1-389.8 and the meter-thick is 131.9-545.7 t/ha of humus. Using the paired determinations of the humus and total nitrogen content of other sources, the average statistical C:N indicators of the profile distribution were also calculated. Using data on the content of humus and C:N, the total nitrogen reserves for the calculated layers were obtained. Mineral nitrogen is available to the root system of plants, the content of which in the total nitrogen reserves varies from 0.5 to 1.0% depending on the soil subtype; in the arable horizon of the zonal soil subtypes, it is 41.04 -80.82 kg/ha. The difference between the required amount of nitrogen for the formation of a wheat crop of 3 and 4 t/ha and the content of mineral nitrogen in the arable horizon of soils represents a dose of nitrogen fertilizer. After adjusting the coefficients of its use from soil and fertilizers, the dose of nitrogen fertilizers is 134-142 and 184-192 kg/ha.

Biochar in technologies for the reclamation of bushy idle land

DOI 10.24411/1029-2551-2020-10017

Under the conditions of a model field experiment in a crop rotation link, we compared the agronomic efficiency of embedding of derivative products of wood-shrub vegetation in the form of wood chips and biochar into the heavy loamy soil of the reclaimed idle land. A significant advantage of biochar was established when it was applied both in pure form and in conjunction with traditional chemical ameliorants. In the year of their application, a decrease in the yield of annual herbs by 55 and 46%, respectively, was observed. Against the background of ploughed wood chips, there was deterioration in the feed value of products due to a decrease in the content of crude protein and ash substances. The combined use of wood chips and biochar with a complex of chemical ameliorants allowed not only to prevent the noted damage but also to increase the productivity of the crop rotation link by 18 and 28%, respectively. The productivity of the crop rotation link when applying biochar was 21% higher than when plo ughing chips. Against the background of a complex of ameliorants, this superiority decreased to 9%. A reduction in the potential for carbon dioxide deposition into the atmosphere when biochar was applied was 3.5–4.5 times lower relative to the technologies of tree and shrubbery vegetation reduction adopted today. With the combined application of biochar with a complex of ameliorants, the maximum indicators of optimization of acid-base properties, nitrogen and phosphate regimes of the soil, as well as the quality of the green mass of annual and perennial grasses were achieved.

DOI 10.24411/1029-2551-2020-10019

In the conditions of the Sverdlovsk region in 2015-2019 in a stationary field experiment on dark gray forest soil, studies were conducted to study the impact of biofactors (manure, siderate, straw, clover, peas) on the yield of spring crops in field crop rotations. It was found that when plowing rapeseed on siderate in a steam field with 1 t on of ash weight, 11.0 kg of NPK entered the soil, with clover Otava – 13.0, with powdered rapeseed-10.4 and with straw - from 20.2 to 24.2 kg. The manure system of fertilizers in the grain-grass crop rotation provided the maximum total supply of the main elements of nutrition to 1 ha of the crop rotation area. When using siderates, solo-we and due to nitrogen fixation with annual and perennial legumes, on average, about 73.1-88.3 kg/ha of NPK is supplied. In grain-grass crop rotations, the share of biological nitrogen was 42.1-54.6% of the total number of accumulated elements of nutrition. On a wind-fed background, the highest yield of spring wheat is obtained when it is placed on a bed of clover and sideral steam, on barley-after glue and pure steam (the second culture). Application of mineral and their combinations with bio-factors practically leveled a difference in productivity of spring grain crops between predecessors. The greatest crop gains from the use of fertilizers were achieved on spring barley, the payback of 1 kg of NPK on the mineral background of nutrition was 14-20 kg, on the organomineral-about 11.5-13.7 kg of grain.
