This paper examines the Stanovoye 4 site-chronology, which was developed through several radiocarbon dating efforts throughout the last two decades. Today, the dates indicate longterm cultural traditions at the site, lasting over 3000 years. The goal of this paper is to understand the site chronology holistically, which is done through a critical review of all available dates and sample characteristics. Additionally, the choice of sample materials, dating methods and preservation practices will be discussed. Furthermore, the dating of PVA-consolidated samples is discussed from an archaeological standpoint.

Spring wheat is the main grain crop. Stable production of high-quality wheat grain is the key to the country's food independence. Therefore, the study of the elements of growing spring wheat technology, aimed at increasing the productivity of crops, is important. The study of the interaction of plants and microorganisms depending on the level of mineral nutrition in crop planning is currently ofparticular relevance. The use of biological products, growth regulators improves the mineral nutrition of plants, increases productivity and its quality, and also provides savings in mineral fertilizers. In the upper Volga region, the main spring crops are wheat, barley and oats. To further increase them in the region, it is necessary to study the characteristics of the formation of yields and determine the most productive crops depending on the level of nutrition, biological products and growth regulators. The scientific article presents the results of the study of these drugs on the productivity of spring wheat. In field experiments, it was planned to get 30, 40 and 50 tons of grain per hectare. Fertilizers for the planned harvest were made taking into account the agrochemical properties of the soil. From biological products used Flavobacterin, which has a protective effect against diseases and improves product quality, from growth regulators used agrochemicals HUMATE + 7 (10 % liquid concentrate), which is characterized by high biological activity. The yield level was determined taking into account the average long-term moisture supply and qualitative assessment of arable land. The indicators of photosynthetic activity of crops, crop and its structure, quality characteristics of grain and economic efficiency of growing spring wheat in the upper Volga region are presented. As a result of researches the optimum level of mineral nutrition for wheat, the efficacy of agrochemical diazotroph and programming yields of spring wheat, determined the photosynthetic activity of crops and grain yield, calculated economic efficiency of the studied techniques and established the qualitative characteristics of the crop. The program for obtaining the planned wheat yields in the years of the experiments was completed by 68-91 %. Close to the planned the program was implemented using a biological product and growth regulator-74-91 %.

Представлены результаты многолетних исследований по изучению характера годовых изменений структуры поливидовых посевов кормовых культур, их густоты, ботанического состава и продуктивное долголетие на потенциально бедных дерново-подзолистых почвах. Установлены годовые изменения плотности травостоя поливидовых посевов клевера и люцерны со злаковыми травами, в том числе и такой нетрадиционной для области как фестулолиум. Выявлено, что наивысшая плотность травостоя клевера наблюдается на второй год хозяйственного использования — 490 шт. стеблей на 1 м2 на контроле и 536 шт. на фоне минерального питания, с годами она резко снижается, а у люцерны изменчивой она остается высокой, значительно не меняясь. В смешанных посевах с клевером его доля снижается от первого года пользования к четвертому от 63,1–75,1% до 15–26%, а у люцерны изменчивой, напротив, увеличивается с 35,2–43,0% до 80,5–85,5%. Максимальные показатели продуктивности массы, сбалансированной по питательным веществам, обеспечивают смеси клевера и люцерны с фестулолиумом — соответственно 6,49 и 9,29 т/га сухого вещества, 5,83 и 7,65 тыс./га кормовых единиц, 654 и 1103 кг/га переваримого протеина на контроле и соответственно 7,6, 6,94, 690 и 9,89, 8,73, 1160 на фоне минерального питания. Сахаропротеиновое отношение по мере старения посевов снижалось, близким к норме оно было на контроле у клевера с фестулолиумом — 0,75, на фоне минерального питания — у клевера с фестулолиумом и райграсом — 0,82 и 0,88 соответственно.

Results of long-term researches on ways of creation of long - term highly productive legume-cereal grass stands on the basis of uncommon for the Ivanovo region culture-Festulolium are presented. As a result of research, for the first time in the region, an adaptive technology of cultivation of perennial grasses in mixed crops with the participation of this culture has been developed, which provides a balanced sugar-protein ratio of high quality feed and increases soil fertility. The main indicators of the technology: high adaptability to soil and climatic conditions, consistently high yields, balance and high nutritional value of green mass, increasing soil fertility due to the accumulation of a significant amount of biological residues and nitrogen, especially symbiotic, efficiency and effectiveness. The average for three years in a single crop Festulolium was characterized by the highest yield of fodder units among perennial grasses and have provided 3,88 thousand/ha of fodder units in the control and of 5.98 thousand/ha on the background of mineral nutrition. In the conditions of the upper Volga region, in order to increase the production of high quality ready-made feed, it is necessary to grow grass mixtures consisting of festulolium and basic perennial legumes, such as clover and alfalfa, variable in a ratio of 1:1, which provide a yield of green mass depending on the level of nutrition from 412 to 571 kg/ha, the collection offodder units from 6.63 to 8.99 thousand units/ha, digestible protein from 756 to 1024 kg/ha. The effectiveness of the technology is determined by low cost, high level of profitability up to 500% and cost recovery - 4-5 rubles./1 rubles costs, as well as environmental friendliness.
