Promising forms for use in breeding programs are identified.

Features of the biochemical composition of winter fodder plants in the Indigirka river basin

The article describes the value of the feed of winter pastures in the extreme north of Yakutia. Winter pastures of the Momsky district are located in marsh places and are used as horse food. Equis?tum fluviatile grows on pastures. Equis?tum Fluviatile is winter-green plants. Equis?tum Froviatile is of the greatest value for the horses of the Momsky district. The research was carry out in the Chiskhan peasant farm of the Momsky district, in the Ulakhan-Chistay village and at the Mercury peasant farm in the Myandigi village of the Amginsky district of the Republic of Sakha (Yakutia) at the end of November. 2020. Samples of winter feed take from pastures near the floodplain of the Moma River, which consisted mainly of marsh horsetail. In the Amga district, a cereal plant - creeping wheatgrass is the standard fodder for Yakutian horses; We are study the biochemical features of Equis?tum Froviatile in the conditions of the Arctic, which complement and expand ideas about the signs of the accumulation of nutrients in winter feed, depending on the cultivation zone. Winter pastures consisted mainly of Equis?tum fluviatile. In the Momsky district, the indicators are higher in cheese protein - 3.05%, for raw fat by 1.65%, for raw materials of fiber by 13.44% than in the Amginsky district. In the Momsky district, the indicators are higher in macro microelements by 1.5-2 times. It is assumed that plants of the Far North accumulate a significant amount of minerals due to their adaptive properties to growing conditions and have a high ability to absorb mineral compounds from the soil.

The choice of the city of Moscow and the Moscow region is due to its significant contribution to the food security of the country, as well as the distribution of unique fodder crops and conditions for them. In addition, Moscow Region is home to the country’s leading institutions in the field of fodder production and phytosanitary safety. Conference Objective to unite efforts of domestic and foreign scientists in solving urgent issues of economy and photosanitary safety of fodder plants introduction. Over the past few years, positive trends have been observed in the agricultural economy. First of all it is connected with the import substitution program, as well as with the new Doctrine of Food Security of the Russian Federation adopted by the President. In this regard, scientific institutions should play a special role in the chain of ensuring presidential decrees. List of Organization Committee, Program Committee are available in this pdf.

The problems of breeding new varieties of forage and other plants for improving the soil in organic farming in Russia

In the agriculture of Russia, organic farming is still relatively uncommon, aimed at obtaining ecologically pure food products of the highest quality category. Such agriculture is characterized by minimal use (up to complete rejection of the use) of various pesticides and other agrochemicals. Tillage under such a farming system is also minimized. At the same time, the use of green manure plants is of great importance. The most famous of these is the seradella. But this culture is most common in the southern regions. In Western Europe, it has been used for this purpose for hundreds of years. On the territory of our country, other crops are used and mainly these are fodder plants: yellow lupine, narrow-leaved lupine, white lupine, hedgehog, perennial ryegrass, white mustard. gray mustard, spring rape, winter rape, spring vetch, winter furry vetch, meadow clover and many others. To create specialized varieties, the main thing is to select plants that, to the maximum extent, will be able to suppress the development of weeds, increase soil fertility, and make poorly soluble nutrients available. In our country, there is a huge number of soil differences and climate features (temperatures, rainfall and their distribution by seasons, etc.), therefore, the creation of one variety of each crop for the entire country is extremely difficult. The requirements for green manure and normal use of plants of the same crop differ sharply. For example, the presence in fodder plants of hydrocyanic acid, glucosinolates and other substances toxic to animals is unacceptable, and their presence in green manure crops, as a rule, is not harmful, and often useful. There are also differences in the requirements for the rate of development and longevity of varieties. Therefore, the standards for breeding varieties intended for green manure fallows or cover crops differ significantly from the requirements for a variety for other purposes - such varieties should be distinguished by rapid seed germination, rapid growth of green mass, such varieties may not differ in longevity, since they are used for one season, often they winter hardiness is not needed. Work in this direction has begun, there are specialized first varieties, but for many cultures this work is just beginning.

Ecological restoration of fodder productivity of degraded pastures in the foothill desert zone of Central Asia

Irrational, ecologically unregulated economic activity in the vast deserts of Central Asia has led to biodiversity depletion, decrease in the fodder productivity of natural pastures and, as a result, deterioration in the fodder base of grassland farming. Forage production of these degraded pastures requires ecological restoration. To enrich the species composition and to increase the fodder productivity of degraded pastures we conducted strip sowing of black saxaul. Restorative succession on degraded pastures led to the formation of a long-term halophytic shrub-ephemeral pasture community consisting of two layers: upper (I) layer represented by black saxaul and lower (II) layer composed of ephemeroids, ephemerals and annual saltwort. Ephemerals are short-growing fodder plants (March–April); Haloxylon aphyllum refers to long-growing (226–242 days) fodder plants, which sprout in the period from late March to early December. Annual salsolas Salsola carinata and Halocharis hispida develop well under the crown of Haloxylon aphyllum. Here they are much larger than between the crowns. The shrub-ephemeral pasture community is dominated by annual grasses and Poa bulbosa. They are mainly concentrated on the outer border of the undercrown ring and are characterized by lush development. In the halophytic semi-shrub-ephemeroid pasture community, the total yield of forage mass of ephemera was 0.90 t/ha; the total yield of forage mass of annual saltwort was 0.14 t/ha; the total yield of forage mass of Haloxylon aphyllum was 0.89 t/ha; the total yield of forage mass was 1.93 t/ha.

Diet and Nurturing Behavior of Asian Elephant (Elephas maximus Linn.) in Some Selected Habitat of Northern Odisha, India

The Asian elephant's (Elephas maximus) nurturing behavior with food fondness was deliberate in Northern land of Odisha during February 2017 to December 2019.The foremost objective of the existing survey is to document the forage plant species intake by Asian elephants. Though the respective study area harbors a noble quantity of plant types, only 146 species were identified as fodder plants which have been consumed by elephants in this survey period. The food path of elephant was identified as branch flouting, bark flaking, twig infringement, flower tugging and stem twisting and uprooting in different regions of study area throughout altered seasons. Adaptation of principally browsing strategy with that of grazing around the year was related to seasonal variation of diet plants as per the availability. This survey elucidates that total 146 species of forest plants belongs to 55 Families and 19 species of non-forest plant belongs to 8 Families. The extensive consumable plant species by elephants i.e. Aegle marmelos (Bel), Careya arbore (Kumbhi), Bauhinia racemosa, Kydia calycina, Bauhinia vahli(Siali), Helicteres isora(Orola), Madhuca indica (Mahulo), Zizyphus mauritiona (BaraKoli), Artocarpus heterophyllus (Panasa), Shorea robust(Sal),Limonia acidissima (Kendu), Smilax zeylanica (Muturi) and Diosporea species. They were affectionate fruits of Mangifera indica and Artocarpus heterophyllus in summer, bamboo during rainy and Madhuca indica during winter. Minuscular analysis of elephant’s dung showing an extraordinary variation in typical dicot- monocot proportion recommended that the food plant collection of elephant was extremely seasonal and unscrupulous.

BIOGEOCHEMICAL EVALUATION OF THE VEGETATION STATUS OF REINDEER PASTURES OF THE NADYM DISTRICT OF THE YAMAL-NENETS AUTONOMOUS DISTRICT

The chemical elemental composition of the most widespread species of wood (Betula pubescens, Larix sibirica, Pinus sylvestris, Salix lanata), shrubs (Vaccinium vitis-idaea, Ledum palustust sl), herbs (Eriophorum angustifolium, Equisetum arvense) and lichens (Cladonia stellaris, Cladonia stygia). The concentrations of Cr, Co, Ni, Cu, Zn, Ga, As, Y, V, Na, Mg, Si, P, S, K, Ca, Ti, Mn, Fe, S obtained using the method of retgenofluorescence energy dispersion analysis. The features of the local biogeochemical background of plants are revealed and their geochemical specialization is studied. The greatest difference in the level of accumulation between different plant species was found for Ni, Zn, Ca, Mn, S, and Si. The analysis of the accumulation coefficients of chemical elements in plants relative to the local background level is carried out. Statistical significant differences in the elements accumulation by plants in different bioclimatic zones were revealed for Cu, Fe, Co, Cr, As, Mg, V, Y. The studied plants according to environmental safety criteria and the content of normalized micro- and macrocells mainly meet the requirements for fodder plants. The exception is the low content of nutrients Co, Na and K. For the prevention of animal diseases associated with a deficiency of essential elements, it is necessary to optimize the diet of deer by enriching feed with biologically active substances and macro- and microelements.
