The article presents the results of long-term research on the adaptive potential of plants of the genus Iris of the family Iridaceae in the Northern forest-steppe of Western Siberia. An assessment of the morphobiological features of irises was carried out, the timing of flowering and the amount of positive temperatures necessary for the onset of such phenological phases of development as regrowth, budding, flowering and fruiting were determined. The indicator role of phenolic compounds and peroxidase in iris leaves during seasonal development was revealed. The studied indicators can be used as an informative parameter for evaluating the state of plants for phyto-indication and introduction.

Grain cleaning-and-drying units for agricultural enterprises in the zones of Western Siberia with high grain humidity are substantiated. Such zones include part of the Northern forest-steppe lowlands, part of the forest-steppe foothills, taiga and subtaiga zones of lowlands and foothills. Grain cleaning-and-drying systems in these zones should provide the possibility of both single and double drying of grain. In order to achieve this, they are recommended to be equipped with two dryers or one dryer with two shafts with the possibility of parallel or sequential operation. Three sizes of systems have been identifi ed with the daily capacity of 100, 200 and 400 tons. Alternative versions of technological schemes of the units have been developed, technical and economic evaluation carried out and the boundary conditions of their application defi ned. It has been established that the choice of the unit will be mainly determined by the level of fi nancial or labor resources available. In the units with the capacity of 100 tons/day, the preferable way of grain handling is by the fl ow line method, which requires some additional capital investment. For the units with the capacity of 200 and 400 tons/day, the most effective option is grain processing and reserving it in the operating silo. The best technical and economic performance is achieved by units with a higher daily capacity.

Objective of research: to study the nematode infestation of the sable and pine marten in Western Siberia. Materials and methods: Altogether 169 individuals of the sable and 18 — of the pine marten were investigated using the method of partial dissection of the gastrointestinal tract and lungs. Animals were caught according to the hunting license in 2009-2011 and 2014-2015, in 8 areas of Western Siberia from the south taiga to the northern forest-steppe. Results and discussion: We have found four species of parasitic nematodes, two of which (Crenosoma petrovi, Filaroides martis) were localized in lungs and two species (Capillaria putorii, Strongyloides martis) — in the intestine of the sable and the pine marten. Prevalence of lung nematodes was 80%, intestine nematodes — 40%. Intensity of infestation ranged from 26 to 358 nematodes per animal. F. martis is the most pathogenic and most common helminth in martens in Western Siberia. 53,3% of pine martens and 26,5% of sables were infected with this nematode species. Nematode S. martis is the most abundant in the intestine. In pine martens the extensity of invasion was 42,8%, the abundance index — 8.29 helminths per animal; in sables — 9,1% and 1.18, respectively. Pine martens were infected by F. martes and S. martis more than sables (p — 0,05). Prevalence increases in the direction from the North East (taiga) to the South West (sub-taiga), which determines the intensity of the helminthiases focus in biocenoses of Western Siberia. Infection of pine martens in the forest-steppe was not detected. In 2014–2015 compared with the previous study period (2009–2011) the extensity of invasion with intestinal nematodes increased by 1,5–2 times, and with highly pathogenic lung parasites — by 3 times. The increase in the helminth infestation may be explained by the growth of animal population density.

Recreation is the most important part of modern life. However, in Russia, there is still underdeveloped an internal and, especially rural (ethnographic) and archaeological tourism. The paper analyzes the possibility of organization of educational recreation for people in the territory of the Bolshechensky district - one of the most touristic regions in the Middle Irtysh. As a result, the author comes to the conclusion that there are several areas which are the most suitable for the specified activity: this is a chain of old Russian villages, the area of compact residence of Tatars - descendants of immigrants from Central Asia, unique places of archaeological heritage sites (the Batakakovo and Inberen meander core, Chigar meander core etc.). For these places, several types of routes are offered (linear radial, radial-ring, etc.). Being of various archaeological and ethnographic themes they make it possible to show the tourists the traditional routine of the rural population, archaeological sites of different types and archaeological excavations.

A new cultivar of smooth bromegrass (Bromopsis inermis Leyss) Flagman was developed by methods of mass selection and polycross. Breeding and wild forms of various ecological and geographical origins are used as an initial material. The authors of the cultivar: Kazarinova I.N., Polyudina R.I., Straub A.A., Gomasco S.K. Studies were conducted on the Central experimental base of the Siberian research Institute of fodder crops of the Siberian Federal Scientific Centre of Agro-BioTechnologies of the Russian Academy of Sciences, located in the forest-steppe zone of Western Siberia (Novosibirsk region, Novosibirsk district, Krasnoobsk). The cultivar is mid-ripening: the period from the beginning of spring aftergrowing to mowing ripeness is 63-75 days and to full maturing of seeds is 95-111 days. The yield of dry matter is 8.3 t/ha, which exceeds the standard by 8%, seed yield - 0.62 t/ha, higher than the standard by 28%. The dry matter yield of the cultivar Flagman for the fourth year of use exceeded the standard by 23% and reached to 11.4 t/ha. The 1000 seeds weight is 3.0-3.4 g. The plant height is 90-140 cm. Tilling capacity is up to 40 stems per tuft. Foliage varies from 32 to 50% depending on the age of the grass and environment conditions. The resistance of the cultivar to brown rust and helminthosporiosis is higher than of the standard. The copyright certificate No. 71916 and patent No. 9653 were received.

Increase In Productivity

Introduction of complex mineral fertilizer of an azofoska in combination with ammonium nitrate and urea to early ripe potatoes of Zhukovsky and Red Scarlett variety on the planned productivity of 40 t/hectare has allowed to achieve a goal. At the same time in control option without fertilizers the productivity was 23,2-24,8 t/hectare. Use of encapsulated urea has led to decrease in productivity and level of profitability by 26,3-30,9%. Early ripe potatoes of Zhukovsky and Red Scarlett variety on natural fertility of the chernozem leached in the northern forest-steppe of the Tyumen region have created average yield of 23,2-24,8 t/hectare for years of researches. Use of complex mineral fertilizer of an azofoska in combination with ammonium nitrate and urea on the planned productivity of 40 t/hectare has led to increase in productivity on the first variety to 39,5 on the second variety up to 41,4 t/hectare. Introduction of the encapsulated urea has led to decrease in productivity of the early ripe potato tubers studied. At the same time, the peel was gentle and when cleaning it was strongly injured. As to the content of starch (11,9-12,6%) at both varieties the big difference between ex-perience options isn't revealed. The similar picture was observed also according to tastes of tubers. It has made 3,2-3,5 points at Zhukovsky variety and 3,4-3,7 points at Red Scarlett's variety. Profitability level in con-trol option at Zhukovsky variety was 157,3%, at Red Scarlett's variety – 140,5%. In options with non-encapsulated ammonium nitrate and urea the first variety got 172,6-184,1%, second variety – 190,4-207,2%. In option with encapsulated urea at varieties under study the profitability level has decreased 26,3-30,9.
