AGRICULTURE AND CHEMICALIZATION
The paper outlines the rationale for new methodological and methodical approaches to the design of rational land use based on comprehensive study of landscape features of such natural- production systems as agricultural enterprise, brigade, field. It is shown that socio-economic, technological and environmental conditions that have changed over the last two decades are a prerequisite for transition from zonal systems of agriculture to adaptive landscape concept, which is based on the methodology of differentiated agroecological assessment and land typification. Implementation of new methodological approaches is preceded by the development of regional landscape-ecological classification of the lands, which reflects the diversity of territory landscape conditions. The method of land agroecological assessment includes all landscape components survey of a given territory and limiting factors identification, on the basis of which agroecological land typification is carried out. The space images and digital cartography tools are used for mapping the territory. There is described agroecological assessment procedure and results of 600- hectare production site on the territory of Kubanskoe ZAO, Kargatsky District, Novosibirsk Region, located in the eastern part of Baraba Plain. Based on the detailed study of solonetz agrolandscape components such as relief and microrelief, groundwater, soil properties and the nature of the soil cover, the main limiting factors have been identified, that limit crop yields and using modern technological methods. They are periodic waterlogging, salinization, alkalinity and shallow contouring of the soil cover. There is given an example of application of landscape-ecological classification having been worked out by the authors earlier for lands grouping (typification). Some data of the comparative economic evaluation of differentiated use of the studied area are presented.
There are reported test results of biological and economic efficiency of herbicide tank mixtures of Concept 1.0 l/ha + Harmony 0,005 kg/ha, Concept 0.8 l/ha + Command 1.0 l/ha and Concept 1.0 l/ha + Command 0.8 l/ha carried out in 2015-2016. The researches took place in the soybean crops on the meadow brown podzolized soils of Primorsky Territory. Concept of 1.0 l/ha norm was used as standard. It showed high activity against annual grass weeds (Echinochloa crusgalli, Setaria glauca,Setaria viridis, Eriochloa villosa), dicotyledonous annuals (Abutilon theophrasti, Sigesbeckia pubescens, Elsholtzia pseudocristata) and perennial (Sonchus arvensis, Artemisia vulgaris) species. Concept 1.0 l/ha + Command 0.8 l/ha and Concept 0.8 l/ha + Command 1.0 l/ha mixtures promoted a significant increase in herbicidal effect on Ambrosia artemisiifolia, Cirsium setosum, Artemisia vulgaris, Commelina communis and Equisetum arvense. Tank mixture processing with Concept 1.0 l/ha + Harmony 0.005 kg/ha increased significantly inhibition of Artemisia vulgaris and Cirsium setosum. There was registered Acalypha australis to be resistant to Concept and its tank mixtures with Harmony and Command. In comparison with the untreated control, the yield increase of soybean seeds in the variants of Concept of 1.0 l/ha, Concept of 1.0 l/ha + Harmony 0.005 kg/ha, Concept of 1.0 l/ha + Command 0.8 l/ha and Concept 0.8 l/ha + Command 1.0 l/ha was of 0.26; 0.31; 0.43 and 0.48 t/ha average for two years; economic efficiency was of 2.9; 3.9; 4.3 and 5.5 thousand rubles/ha, respectively. In conditions of southern Far East, Concept herbicide of 1.0 l/ha norm should be applied taking into account the weed species composition and Command process solution must be added in the case of Ambrosia artemisiifolia predominance.
Results are given from analysis of microaggregate composition of virgin and arable gray forest soils and the reasons for its change due to long-term plucking are reported. The researches were conducted on different subtypes of gray forest soil (light gray, gray and dark grey ones) in the subtaiga zone of Nizhnetavdinskyi and Yarkovskyi districts, Tyumen Region. To identify the genetic features of microaggregate composition of gray forest soils, comparative analyses from virgin lands were carried out. It was found that light gray and gray forest soils initially had a favorable microaggregate composition, despite the humus substances deficiency and illuviation process. Virgin dark gray forest soils on the primary structure are similar to chernozem of the Urals forest-steppe zone, though they differ with low aggregate resistance. Dispersion coefficient of humus-eluvial horizon of gray forest soils varies from 4.6–5.0 % in dark gray soils to 15.5–16.4 % in light gray forest ones. Arable analogues of grey forest soils are characterized with the following values of dispersion coefficient: light gray forest – 34.5–40.1 %; gray forest – 19.8–24.3 % and dark gray forest – 15.9–16.6 %. The aggregation degree by Beaver in arable gray forest soils is 2 and more times less than that of virgin lands, which indicates a sharp decrease in microaggregate stability and deterioration of primary structure formation. Dramatic negative changes are observed not only in light gray and gray soil, but also in dark gray one with higher content of humus substances. It has been established that anthropogenic change of microaggregate composition of gray forest soils up to 1 meter depth was caused by moving elementary soil silty particles from the upper layers into the profile.
PLANT PROTECTION
There was studied impact of Dublon Gold, Titus Plus, MaisTer, Stellar and Adengo herbicides on maize sow productivity and weediness. The study was carried out on the experimental fields in Primorye in 2008– 2010 and 2014–2017. Soil was brown meadow podzolized one containing 3.5 percent of humus in the arable horizon. Agrotechnology was done on the base of soil dumping cultivation. Soya was the forecrop. In pre-seeding preparation period there was applied fertilizer of 150 kg/ha. Slavianka and ZPTK 196 maize hybrids under study were seeded of 70 000 seeds/ha. There is shown that application of Doublon Gold (0.07 kg/ha), Titus Plus (0.38 kg/ha), MaisTer (0.15 kg/ha), Stellar (1.5 l/ha) and Adengo (0.5 l/ha prior to germination, phases 2–3 and of 5-6 leaves) herbicides allowed to reduce the number of weeds in maize sowing by 45–82 % and their above-ground mass by 67–88 %. In the control variant (without herbicides) there were registered 244-511 weed plants per square meter average with their total above-ground mass of 2623–4488 g/m2. The increase in maize yields due to herbicides application was of 1.33–5.55 t/ha with the control yielding capacity of 0.3–0.86 t/ha. The studied herbicides are arranged in descending order according to maize tolerance degree as following: Titus Plus, Adengo, Doublon Gold, Stellar and MaisTer. In case of overdose or in the places overlapping sprayer passes, Adengo, MaisTer and Dublon Gold herbicides can have a depressing effect on corn plants and reduce grain yield of the crop by 6–16 %.
PLANT GROWING AND BREEDING
There are presented the estimation results (2007-2017) of oat varieties collection of Siberian and Far
Eastern origin in order to select material for new variety producing. There were studied 5 oat early ripening varieties with shoots - waxy ripeness period of 69 - 72 days and 22 medium-ripening varieties with the period of 73 - 76 days. The varieties were study in the nursery on the leached medium-loamy chernozem in the conditions of Priob’e forest-steppe of Novosibirsk Region. Over the years, there was reported a significant variation in economic valuable characteristics for all genotypes. There were revealed genotypes with high ratio value of yield and panicle productivity average for 11 years to the duration of shoots – wax ripeness period. The greatest average yields were formed by the following varieties: Mutik 559 (632 g/ m2 for 71 days); Novosibirsk 88 (630 g/m2 for 72 days; Monar and Bogachkov’s Memory (638 g/m2 and 649 g/m2 for 73 days); Togurchanin and Sig (661 g/m2 and 649 g/m2 for 74 days); Orion (675 g/m2 for 75 days) and Malysh (686 g/m2 for 71 days). The varieties showed the highest ratio value of the yield to the duration of shoots - wax ripeness period in comparison with the varieties equal in development velocity. Polar correlation indices between shoots - wax ripeness period and productivity were demonstrated by studied varieties of Coryphaeus (r = 0.39 with 609 g/m2 average productivity) and Talisman (r = 0.83 with 671 g/m2 average productivity) and the same varieties showed polar indices of correlation between shoots – wax ripeness period and panicle grain mass (r = 0.18 and r = 0. 80 respectively). Correlation coefficients variation of the varieties confirms a great genotypes influence on development duration and plant productivity. The promising varieties were selected: Mutik 559, Novosibirsk 88, Monar, Bogachkov’s Memory, Togurchanin, Sig, Orion and Malysh on optimal combination of yield and duration of shoots-wax ripeness period; Tayozhnik, Monar, Bogachkov’s Memory, Sig, Orion and Altai coarse- grained on optimal combination of panicle productivity and duration of shoots - wax ripeness period.
MECHANISATION, AUTOMATION, MODELLING AND DATAWARE
The model of spring triticale variety adapted to the conditions of the forest-steppe zone of Western Siberia was developed based on empirical data obtained during breeding. The work was carried out using the results of the analysis of the relationships between the indexes of plant grains mass and morphobiological characteristics of the plant. According to the results of breeding studies of spring triticale in 2009–2016, there was created computer database containing information on productivity, product quality, resistance to diseases, pests and other characteristics. The materials for breeding were intervarietal hybrids of hexaploid spring triticale obtained by diallel crossings of four spring triticale varieties from the world collection of the N.I. Vavilov Research Institute of Plant Industry (Sokol Kharkovskiy, Ukro, Gabo, K-3881) as well as by crossing of these varieties with Sirs 57– a winter triticale variety bred at Siberian Research Institute of Plant Production and Breeding – branch of IC&G SB RAS. A conceptual scheme of the spring triticale variety model was elaborated, revealing a logical sequence of operations required to build a variety model version. We used the practical data to correct the parameters of the model variety that allowed us to determine the limits of variability of the potential yield, provided by the climate resources in a specific soil-climatic zone. The following main parameters of spring triticale variety model were determined: the number of grains of the main ear is 50–60 pieces, the length of the ear is 11–13 cm; weight of 1000 grains is 60 g, grain yield is 50 c/ha.
FODDER PRODUCTION
Results are given of studies on the effect of pre-sowing inoculation with bacterial and growthpromoting biopreparations on seed productivity of goat’s-Rue East (Galega orientalis) grown on acidic (pH of 5.2) gray forest soils of the subtaiga zone of Tomsk Region. The researches were carried out by Siberian Research Institute of Agriculture and Peat in 2006-2010. On the background of the variant without seed treatment there were studied different combinations of rhizotorphine with rhizoagrin, mizorin, sodium humate from peat and albit. It was observed that in the year of sowing, plants adaptability to growth conditions increased due to bio-preparations using. There was also reported symbiotic activity activation and improvement of plants morphometric parameters and acceleration of some development phases. Productive parameters analysis of seed herbage over the application years was carried out and agro-energetic efficiency of biopreparations application was calculated as well. The positive effect of the complex application of symbiotic and rhizosphere bacteria and growth stimulators on the herbage structure and seed productivity elements was established: in comparison with the control, the number of generative stems per 1 m2 increased by 7.6–17.4 % average, the number of brushes – by 296 %, beans – by 34 %, and seeds yield – by 38.5 % while energy consumption for 1 kg of seeds production decreased in 2.4-3.4 times. Best results were obtained under inoculation with rhizotorphine in combination with sodium humate. Over the application years that variant provided constantly high values of plant productivity parameters and maximum biological seeds yield by 54 % higher than that of the variant without treatment and 18 % more than under inoculation with rizotorphine alone. With energy consumption per hectare increasing, 1 kg of seeds cost in energy units was minimal and equal to 13.8 MJ that was by 33.6 and 5.9 MJ cheaper than that in variants without treatment and under inoculation with rizotorphine alone, respectively.
ANIMAL HUSBANDRY ABD VETERINARY SCIENCE
Results are given from study of efficacy of velvet presscake including into marals’ feeding. Forty five stags at the age of 7 to 10 were divided into three groups of 15 animals each. Live body weight was of 211.3 ± 7.4 kg (control group), 204.6 ± 7.9 kg (test group I) and 207.9 ± 10.9 kg (test group II) and velvet yield was of 7.0 ± 0.45 kg, 7.0 ± 0.62 and 6,9 ± 0.69 kg, respectively. Each test group was isolated for 40 days. Daily diet was comprised of hay – 1.5 kg, silage – 18 kg, oats – 2.5 kg and soybean meal – 0.5 kg. Total food value was of 7.7 fodder units. Velvet presscake dose of 25 g and 50 g per head was added to test groups’ diet with concentrated feedstuff. At the beginning all groups under study did not show any great differences of morph-biochemical blood composition. During experiment the marals of test groups demonstrated moderate increasing in red blood cell count, hemoglobin, total blood lipids, triglycerides, ethers and cholesterol compared to control one. Blood glucose level was not changed. At the end of experiment all animals had a higher level of alkali reserve, calcium and phosphorus. There was reported that low doses of velvet presscake stimulated protein and lipid metabolism. Within first ten days, 43.3 % stags of test group I (velvet presscake dose of 25 g) lost their antler crowns; for test group II (velvet presscake dose of 50 g) and control one the value was of 26.7 %. Average daily gain of live body weight in test group I exceeded the control group by 19.2 %. A higher dose of velvet presscake (50 g) reduced average daily gain by 5.6 % against the control group. Thus, velvet presscake feedstuff dose of 25 g per head increases velvet yield by 13.2 %. Raising the dose up to 50 g per head depresses metabolism processes and reduces animals’ productivity.
There was studied effectiveness of introduction Korean pine (Pinus koraiensis) cone husks into diets of laying quails of Japanese breed as a source of natural amino acids, microelements and other biologically active substances. Experiment of 182 days duration was carried out according to the standard technique in four groups of 50 birds each kept in a cell battery under required microclimate conditions. Quails of all groups received the basic diet (feed), developed taking into account their age and physiological characteristics. Quails of 1st to 3rd experimental groups, unlike the control one were additionally fed with Korean pine cone husks in the amount of 1.5; 2.0 and 2.5 kg/t of feed respectively. There was studied influence of different doses of the additive on laying quails egg productivity, eggs chemical composition and incubation qualities, diet nutrients digestibility, the balance and use of nitrogen, calcium and phosphorus and hematological parameters. It was found that adding a new supplement in amount of 1.5–2.5 kg/t into combined feeds increased poultry egg production by 2.9 and 5.8 %, the intensity of oviposition by 2.0 to 4.0 %, egg weight by 2.70–4.71 %, total egg mass by 5.69 – of 10.83 %, yield of hatching eggs by 2.19–8.58 % and the hatchability of chicks from eggs laid by 6.3 and 8.2 %. At the same time, feed consumption per unit of production decreased by 7.95 – 18.18 %, incubation waste by 33.3 %. Feeding with pine cone husks in the indicated doses increased the digestibility of the diet dry matter by 1.63–2.16 %, crude protein by 1.28 –1.82 %, crude fiber by 0.76 – 3.03 %, the efficiency of nitrogen use for egg formation in 1.12–1.23 times. It was also revealed that feeding with the addition of Korean pine cone husks at the rate of 2.5 kg / t feed had a maximum positive impact on the zootechnic and economic indicators of productive use of laying quails.
PROBLEMS. OPINIONS
The paper considers the current state of the vegetable growing industry in Siberian Federal District over last quarter of a century. In the Siberian Federal District, 1.5 million tons of vegetables are produced annually, and according to rational food standards, 2.8-3 million tons are needed for the district population, i.e. 1.5 million tons should be brought in. Vegetable producing was rather stable in Siberian Federal District over 1990–2015. Novosibirsk, Omsk and Kemerovo regions and Altai and Krasnoyarsk territories are the main district suppliers of vegetable production for their own needs and other regions as well. Republics of Altai and Tuva do not produce vegetable cultures due to unfavorable nature-climatic conditions; they take the 11th and 12th places among Siberian regions. On the database of the Federal State Statistic Service over 25 years, there was analyzed use of land sown to vegetables, dynamics of vegetables croppage and productivity in the Russia Federation and Siberian Federal District. Vegetable crops productivity was influenced by advanced technologies of vegetable growing on covered soil such as hydroponics, drip irrigation and vertical vegetable growing. In modern greenhouse enterprises, productivity can reach up to 180 kg/m2. A series of factors limiting vegetable growing development is pointed out. Indicators of the industry development up to 2025 are calculated and measures for their achievement are suggested.
