The research was out on low-humus heavy-duty heavy-clay merged leached chernozems in 2017–2020 in the Republic of Adygea, in the soybeans – winter wheat link of crop rotation. We studied the effect of soil cultivation techniques of varying intensity and fertilization level on the productivity of winter wheat and the agrophysical properties of the soil in its crops. The studies were carried out according to the method of the field experiment by B.A. Dospekhov. It was found that moldboard plowing was a more effective method for cultivating winter wheat, which provided additional formation of +1,18 t/ha (25,7%) of grain in comparison with double disking; sowing of winter wheat provided the maximum yield on the variants with the application of doses of Fon mineral fertilizers (N24 P104 + N5 P20) + N30 + N30, which contributed to the receipt of an additional +0,9 t/ha (18.8%) of grain. The effectiveness of the use of fertilizers for all varieties and doses of fertilizers according to the variants of the experiment was noted. Close correlations between productivity and a set of characteristics: the mass of grain from one spike; the number of grains in an ear; weight of 1000 grains; the total number of plants and productive stems were revealed. The positive effect of plowing on the structural and aggregate composition of the soil was noted. The average indices of the volumetric mass of the cultivated layer by both methods of cultivation did not exceed the optimal values of soil density for the cultivation of winter wheat (1,24–1,27 g/cm3). Productive moisture reserves were assessed as good and satisfactory. It was found that from 51,0 to 88,0% of the yield variability depended on the influence and mutual influence of the most significant elements of the yield structure (R2 is the coefficient of determination 0,88; 0,77; 0,51).

In 2016-2019, research was conducted on the experimental field of the Ulyanovsk research Institute for the purpose of determining the effectiveness of starting doses of mineral fertilizers, as well as nitrogen fertilizing on the productivity and quality of winter wheat grain Marathon. Studies have established the optimal lead time of nitrogen fertilization and doses of mineral fertilizers. Weather conditions over the years of research were contrasting, which allowed us to assess the responsiveness of winter wheat to mineral fertilizers in conditions of different moisture availability. The most effective options were those with nitrogen fertilization at a dose of 34 kg/ha in the spring period on frozen soil, which allowed to obtain an additional 0.51 t/ha and, conversely, the lowest-in the autumn period (+0.16 t / ha). The maximum yield of winter wheat (3.72 t / ha) is formed during the seeding with the simultaneous introduction of 45.5 kg/ha of complex fertilizers in the rows against fractional application of ammonium nitrate in spring during tillering and booting of plants in the amount of 34 kg/ha and top dressing in the phase of earning with urea at a dose of 15 kg/ha. Correlation analysis showed a positive close relationship between the elements of the structure of the winter wheat crop depending on different doses and methods of applying mineral fertilizers and nitrogen fertilizers (r=0.82-0.96). The highest content of protein (on average 14.1%) and gluten (33.0%) was provided on the control background without use of ordinary fertilizers. The use of complex fertilizers during seeding resulted in a slight decrease of amount of protein (by 14%) and gluten (up to 32.4-32.9%). Nitrogen fertilizer had a greater impact on these indicators.

The article presents an analysis of the determination of the effectiveness of mineral and organic fertilizers on the yield of winter wheat grain. The studies were carried out in 2017–2020 in the Rostov region on the southern chernozem. The object of research was the Doneko winter wheat variety. The predecessor is corn for grain. Ammonium nitrate, ANP fertilizer (16-16-16) and urea were used as mineral fertilizers, which were applied in the fertilization system of winter wheat and acted as a background option in the experimental scheme. ANP fertilizer (16-16-16) was introduced when sowing winter wheat, ammonium nitrate - scattered over thawed-frozen soil and carbamide in the heading phase by foliar method. Organomineral fertilizers were represented by the following types: Ruther, Leili 2000, Siamino Pro, Gumiful Pro, Soft Guard and Double Wine MKR (monocaliphosphate) produced by Biokepharm (Switzerland). The raw material for the production of organomineral fertilizers was the algae of the warm seas Laminaria. In the field experiment, the options for the joint application of foliar application and pre-sowing seed treatment with organomineral fertilizers were also studied. The control was the option without mineral fertilizers and the option with the background of the use of mineral fertilizers (farm fertilization system). It was found out that the use of organic fertilizers Ruter (0.5 or 0.25 l / t) and Leyli (0.25 l / t) for seed treatment before sowing, the use of Soft Guard (0.2 l / ha) and Gumiful Pro ( 0.2 l / ha) in the spring tillering phase and in the flag leaf phase against the background of sowing nitroammophoska at a dose of N32P32K32, random fertilizing on thawed-frozen soil with ammonium nitrate at a dose of N40 and the use of carbamide in the heading phase at a dose of N20 increased grain yield on average for 2018–2020 compared with the control (fertilization system of the farm) by 0.73 t / ha, or 23.0%. The maximum yield increase from the root-forming agent Ruther, used for pre-sowing seed treatment, reached 0.36 t / g, or 11.3%.

Winter Wheat Yield

The research aim is to identify the most energy-saving and cost-effective technology for winter wheat cultivation. The maximum moisture content of soil was recorded when it was processed using Mini-till technology – from 17.2% to 17.9%, and the lowest - with traditional technology – from 15.7% to 16.4%. The lowest soil density with traditional winter wheat technology is both on the background with fertilizer (1.18%) and on the background without fertilizer (1.21%). The lowest contamination of crops with traditional technology without mineral fertilizers (42 pcs/м2). With the Mini-till technology, the total blockage increased to 51pcs/м2, and with the No-till technology, it was maximum- 128 pcs/м2. Against the mineral fertilizers, the same tendency of total blockage-from – from 40 pcs/м2 to 132 pcs/м2, respectively. With No-till technology, the total plant damage increased from 17.0 % to 14.6 %, with traditional treatment – from 12.4% to 10.1%, and with Mini-till technology-from 12.7% to 9.6%. The yield of winter wheat when using traditional plowing against the background of mineral fertilizer is 3.59 t / ha, and against the background without mineral fertilizer – 2.24 t / ha. The yield of Mini-till technology for mineral background is 3.13 t / ha, and without fertilizers-1.81 t / ha. With the No-till technology, the winter wheat yield is 1.69 t/ha, and without fertilizers – 1.11 t/ha. The highest level of profitability with Mini-till technology against the background of mineral fertilizers-73.2%.

The effect of fertility on the yields of native perennial grasses was investigated in pot culture and field experiments. Yields of six native perennial grasses and Paspalum dilatatum Poir were determined in the glasshouse at five levels of applied phosphorus (P), sulphur (S) and nitrogen (N) and in the field the biomass of individual tussocks of eight native grasses was compared. In pot culture the maximum yields of the native perennial grasses with P, S and N applied were 15 to 75% lower than those of P. dilatatum. Within the native grasses there were significant yield differences: Bothriochloa macra (Steud) S.T. Blake, Chloris truncata R.Br. and Dichanthium sericeum (R. Br.) Camus yielded up to twice as much dry matter as either Aristida ramosa R.Br., Sporobolus elongatus R.Br. or Eragrostis leptostachya Steud. These data indicate that P, S and N are all essential for maximum yield of some native grasses, and large imbalances in the level of these nutrients resulted in seedling mortalities in most native grasses.

In long-term stationary experiments under different soil-climatic conditions, an influence of mineral and organic fertilization on yield of winter wheat, spring barley and potato tubers was evaluated. Statistically significantly lowest grain yields of winter wheat (4.00 t/ha) and spring barley (2.81 t/ha) were obtained in non-fertilized plots at all experimental sites. In the case of potatoes, the lowest yield of dry matter (5.71 t/ha) was recorded in the control plot, but the result was not statistically significant. The manure-fertilized plot gave the average yield of wheat higher by 30%, of barley by 22%. Application of sewage sludge resulted in wheat yield higher by 41% and barley yield higher by 26% over control. On average, application of sewage sludge and manure increased the yield of potatoes by 30% over control. The highest yield was obtained after application of mineral fertilizers; average yield increased by 59, 50 and 36% in winter wheat, spring barley and potatoes, respectively. No statistically significant differences among the plots with mineral fertilizers were observed. At different sites, the yield of studied crops varied; however, the effect of fertilization on yield increments was similar at all experimental sites except for Lukavec. It is the site with the lowest natural soil fertility, and it showed the highest effect of the applied fertilizers.
