The research explores the relation between productivity of binary grass mixture and mineral nutrition. The hypothesis assumes that nutrient value of the same forage depends on mineral nutrition of forage grasses. According to purpose of research, the authors specified the task which is seen to analyze the impact of mineral fertilizers on productivity and nutrition of forage mass of binary grass mixture sown under the cover. The object of the research is a binary grass mixture based on alfalfa (Medicago + sainfoin). Sowing was carried out under the barley and Sinapis cover on two mineral backgrounds: control (without fertilizers) and fertilized. Fertilizers were applied the day before sowing. Crop yield and the quality of harvested mass were assessed in the appropriate period which was the stage of Medicago budding. Two-year industrial and economic experiment highlighted necessity and efficiency of sowing Medicago binar grass mixtures under Sinapis cover with 25% lower sowing rate and apply mineral fertilizers dosed as N23P60K60 in the forest-steppe of Novosibirsk region. This application contributed to the highest output of metabolic energy in dry matter (37 GJ/ha). The authors observed a positive tendency on harvesting from 1 ha of fodder units (2.14 tons), digestible protein (0.35 tons), as well as the yield of dry (3.58 tons) and green mass (13.7 tons). In this variant the authors observed the highest output of metabolic energy in dry matter (37 GJ/ha). There was a positive tendency to harvest fodder units (2.14 tons), digestible protein (0.35 tons) pro 1 ha and get dry (3.58 tons) and green mass (13.7 tons).

The Impact

The article presents findings of the influence of different levels of mineral nutrition on plant growth and development, the impact of fertilizers on the botanical composition, on the productivity and forage benefits of cereal-bean agrocenoses in the forest-steppe zone of the Baikal region. The objects of research were mixed crops of oats with peas and millet with vetch, peas, and Austrian winter pea. Legumes are the main source of protein increase in feed. In the field, the most widespread, among legumes, were vetch, sowing peas, field peas (Austrian winter pea). As a result of phenological observations, it was found that the growth and development of plants depended on the biological characteristics of crops, weather conditions and directly on the mineral nutrition level. The millet reacted most effectively to the application of mineral fertilizers, starting from the exit phase into the tube. The introduction of mineral fertilizers in pre-sowing tillage contributed to an increase in the proportion of legume components in the total green mass yield and a decrease in cereals. The highest competition in agrocenoses of millet with legume components was vetch, its share in the mixture increased, compared to the unfertilized background, by 6 and 14.5%, depending on the background of fertilizers. It was found that, compared with the unfertilized background, mineral fertilizers increased the yield of green mass from 1.5 to 4.9 tons per hectare, the collection of dry matter from 0.4 to 2.0 tons per hectare and the collection of feed units from 0.3 to 1.3 tons per hectare. Digestible protein content in 1 unit increased with the introduction of nitrogen fertilizer (N45), depending on the type of components in the mixture, from 3.2 to 6.6 g, and with the introduction of complex mineral fertilizer (N45P30K30) from 2.5 to 9.6 g. All are millet-bean mixtures at all levels of mineral nutrition comply with zootechnical standards.

Experimental data on the creation of fodder agrocenoses for the production of green feed in the spring and early summer period is presented. The research was conducted in 2014-2016 in the forest-steppe zone of the Trans-Baikal Territory. The study included winter and spring rye crops and cabbage. It was established that the promising crop that gives the earliest green feed is the winter rye of autumn sowing. It was characterized by a high regrow capacity and formed two yield cuttings in the tillering phase. The yield of green mass was 7.7 t/ha, dry matter – 1.36 t/ha, output of feed units was 1.34 t/ha, the amount of digestible protein – 279 kg/ha. In the phase of stem elongation, the figures were 10.0 t/ ha, 2.17 t/ha, 1.93 t/ha, 287 kg/ ha, respectively; in the earing phase (one cutting) – 9.3 t/ha, 3.30 t/ha, 2.65 t/ha, 287 kg/ha, respectively. Feed biomass was of higher quality when used in the period of tillering, where the content of digestible protein per one feed unit was 206-210 g. The spring sowings of winter rye were inferior to the autumn sowings in the amount of two cuttings in the tillering phase: green mass by 3.3 t/ha, dry matter 0.58 t/ha, feed units 0.58 t/ha, digestible protein 113 kg/ha; in the stem elongation phase: 5.5 t/ha, 1,27 t/ha, 1.15 t/ ha, 168 kg/ha, respectively. Crops of spring rape, oil radish and spring rye are also important, since they allow to obtain a sufficiently high yield in the early summer period. In the budding phase the yield of green mass of cabbage crops was 22.8 and 18.3 t/ ha, dry matter – 2.69 and 2.78 t/ha, feed units – 2.70 and 2.25 t/ha, digestible protein – 648 and 599 kg/ ha; in the flowering phase the figures for oil radish were 21.5 t/ha, 2.56 t/ha, 2.57 t/ha, 499 kg/ ha, respectively. In the tillering phase the figures for spring rye in the amount of two cuttings were 7.3 t/ ha, 1.31 t/ha, 1.11 t/ha, 210 kg/ ha, respectively; in the phase of stem prolongation – 3.8 t/ha, 0.82 t/ ha, 0,87 t/ha, 105 kg/ha, respectively.

The Cost

A powerful factor in increasing the yield of feed mixtures is the use of mineral fertilizers. On average, over 4 years of research, the yield of green mass increases from 13.8 tons per hectare at the control (without fertilizers) to 27.4 tons per hectare (almost 2 times). However, the effectiveness of the use of mineral fertilizers depends on how the sunflower and annual herbs are placed in space. Thus, on all backgrounds of mineral nutrition, the highest yield of green mass was obtained by sowing sunflower and annual herbs in separate strips with strip widths of 180 cm: N85P38K46 - 28.2 tons per hectare; N99P44K54 - 32.9 tons per hectare; N113P51K61 - 34.2 tons per hectare. In the same conditions, both narrowing the bands to 90 cm and expanding to 360 cm reduce the yield of the object of study. Mineral fertilizers also have a great influence on the gross yield of raw fat (an increase of 2.8 times), feed units - from 2,562 to 3,904, crude protein - 1.9 times, exchange energy - 2.4 times. As a result, the payback of each ruble of the cost of mineral fertilizers provides for the production of 1.5 rubles, and the bioenergy coefficient increases to 4.4, versus 2.2 for mixed sowing of sunflower and annual herbs.

The article presents the results of research conducted during 2016-2019 on the impact of different rates of mineral fertilizers and by-products of the predecessor on the content of chemical nutrients in plants and the yield of maize hybrids in the Forest-Steppe. The aim of the research was to establish the peculiarities of nitrogen, phosphorus and potassium accumulation in maize plants in ontogenesis in relation to the yield of hybrids of early and middle-early maturity groups to optimize the mineral nutrition of the crop. The research was conducted on dark gray wooded soil using field, chemical, calculation-weight and mathematical-statistical methods. According to the stages of growth and development of BBCH, the peculiarities of the dynamics of nitrogen, phosphorus and potassium content in plants of hybrids with FAO 190 and 280 depending on the agrochemical load of growing technology are established. Varietal regularities of concentration of chemical elements in maize plants in connection with the accumulation of dry matter by crops in ontogenesis and yield were revealed. Hybrids with the corresponding genetically determined level of nitrogen, phosphorus and potassium content in plants have been identified and its influence on the realization of genotype productivity potential has been shown. The decisive role of potassium and nitrogen in the formation of the corn crop on dark gray wooded soil has been experimentally proved and confirmed on the basis of statistical and correlation analyzes. All hybrids were characterized by high tightness of correlations between yield and content in plants of nitrogen (r = 0.760–0.934) and potassium (r = 0.755–0.943) during the growing season as opposed to phosphorus, where these connections were of medium strength (r = 0.334–0.589) and only partially close (r = 0.702–0.806). According to the results of plant diagnostics of mineral nutrition of plants, the most effective growing technologies with different agrochemical loading are singled out, which ensure the yield of early and middle-early maize hybrids in agro-climatic conditions of the Forest-Steppe at 9.56–10.39 and 11.21–12.10 t/ha.
