Relevance. In recent years, interest in the edible honeysuckle culture has increased in Russia, the wide distribution of which is hampered by the lack of quality planting material. The technology of clonal micropropagation allows for a short time to obtain a large amount of honeysuckle planting material, more than a thousand regenerated plants per year from one meristematic apex introduced into an in vitro culture. It is hundreds of times more than in traditional methods of vegetative propagation. Adaptation to non-sterile conditions is the final and most crucial stage of clonal micropropagation, the loss of which can be from 50 to 90%. It should be noted that there is practically no research on how the further development of adapted honeysuckle plants takes place during subsequent growing.Methods. Researching of growth regulators of the new generation Superstim 1 and Superstim 2 effect in low and ultra-low doses on the survival rates and development of honeysuckle plants at the stages of adaptation subsequent growing.Results. Superstim 1 is more effective at physiological concentrations – 1 x 10-7 and in the field of ultra-low doses – 1 x 10-14, 1 x 10-15%. At the stage of subsequent growing, a positive after-effect of physiological concentrations – 1x10-3 and 1x10-7 was observed, and an ultra-low dose – 1x10-17%. The growth regulator Superstim 2 at the stages of adaptation and subsequent growing is effectively used only in one concentration – 1x10-16%. The additional foliar treatments at the stage of subsequent growing are not necessary.

Expanding the range of vegetable crops, including green ones, through the introduction of new varieties into production is an important task. The study and evaluation of the original material of the salad, the features of cultivation in different periods, will allow to identify samples of a complex of economically valuable traits for the selection of culture, which is relevant for the creation of varieties in Belarus. Research was carried out on the experimental field of the Department of horticulture of the Belarusian state agricultural Academy in 2013-2015. The article assesses the relationship between the main economically valuable features of varieties of lettuce when grown in the spring (seedling method) and spring and summer sowing in the open ground. In lettuce plants of the headed variety, the sign “the mass of the vegetative part of the plant” strongly depends on the sign “diameter of the head” (r=0.640 - with the seedling method and r=0.809 - with the spring sowing period), “leaf width” (r=0.685 and r=0.790, respectively). A high connection is also established between the signs "leaf length" and "leaf width" (r=0.702 - with the spring sowing period and r=0.749 - with the seedling method). In leaf lettuce plants, a strong correlation was noted between the signs “leaf length” and “plant height” (r=0.706 for summer and r=0.810 for spring planting), diameter of the rosette of leaves (r=0.564 for summer and r=0.810 - at the spring sowing time). The average feedback for leaf lettuce varieties is revealed between the signs “leaf width” and “number of leaves” (r=-0.444 - for spring and r=-0.458 - for summer sowing time). The majority of morphological signs, depending on the time of cultivation, are related to each other by average correlation links (the correlation coefficient ranged from 0.458 to 0.531).

Relevance. In many ways, a successful purchase and sale transaction is determined by the time it takes to complete it. The search for the best deal time is linked to the optimization of the time lag. The purpose of the study is to optimize the time lag of the agricultural market.Methods. This article considered a role of time in business processes for Russian potato market of producer into period 1998-2018.Results. There was trend of annual reduction about 365 thousand tons (1.2...1.7% of total) per year supply of potatoes on Russian domestic market of producers. Some priority of quantity vs price of producer been revealed. There was inverse proportional function between producers` prices and quantity of potatoes. That is than worse harvest that higher producer`s price. Reducing a supply of potatoes 1 million tons from agricultural market perhaps increase in producer prices by $ 8.5 / t (4...5% on average). Offered concept and hypothesis about linearization of equilibrium of market processes into conditions of time shifts of dynamics their parameters were confirmed. There verified assumption about existence of inter-interval time optimum which this linearization maximal business processes. In course of correlation analysis of dynamics of annual indicators of potato market, it revealed month May of current period as optimal time of producer's offers with price restrictions and diminishing returns, and month September with quantity restrictions and increasing returns. If fixation of producer`s prices situation of deals May more likely, in case of crop failure (limited quantity) in September.

Tarragon (Artemisia dracunculus L.) is a spicy aromatic culture, perspective to use in the food and medical industry. In the collection of aromatic and medicinal plants of the Nikita Botanical Gardens, tarragon is represented by two varieties: Isumrud and Travnevy. The Isumrud variety is characterized by a high content of essential oil (0.6% of the wet weight) of the methylchavicol chemotype (the main component of the essential oil is methylchavicol, whose mass fraction is up to 91%) and is perspective to use not only as a spice, but also in medicine as a reducing facilities. The variety Travnevy contains only 0.1% of the essential oil from the wet mass of the sabineno-elemicin chemotype (the main components of the essential oil are sabinen (40.0%) and trans-from-iso-elemicin – 26.1%), characterized by high productivity of the aerial mass (12 kg/m2 ), the main direction of use in the food industry as a spice. Due to the lack of requirements for dry raw tarragon, we have developed a draft technical specifications for dry crushed tarragon raw materials TS 01.28.30-009-01579640-2018. Specifications apply to dried whole and crushed raw materials, intended for the manufacture of water and water-alcohol infusions, as a source of biologically active substances, as a component for seasonings to meat, fish dishes, for use in cooking, as well as in the production of alcohol and soft drinks. The main physicochemical indicators of whole and crushed tarragon raw materials (type, size, smell, taste, mass fraction of essential oil, impurities, moisture, ash) are presented.

Implementation of cell technologies has essentially improved the plant breeding process in agricultural crops in the world. The production of pure lines in cultivated crops, particularly among cross-pollinated species such as cucumber (Cucumis sativus L.) requires much time, labor and expense. Thus, the use of DH-plants for production of fully homozygous lines for one year becomes a very promising method for near cucumber breeding program. The major factor limiting the wide use of DH is a lack of effective protocol for large-scale plant production. In this review the historical facts with description of three main methods of DH-plant production were presented. By now these three methods have been such as parthenogenesis in situ induced by pollination with irradiated or chemically treated pollen; androgenesis in vitro including anther and isolated microspore cultivation in vitro; gynogenesis through ovule cultivation in vitro. Comparative analysis of published data with regard to the efficiency of the technology for DH-plant production was shown as well as advantages and limitations of each technology were described.

The Issyk-Kul region is one of the most preferable for horticulture regions of Kyrgyzstan. However, during last decades the biological and agronomical diversity in this region is significantly decreasing due to transmission to market economics. In this term the aim of our survey was estimating of present level of diversity of fruit trees and wild berries, as well as vitamin content after long winter storage. This survey was organized in two districts of Issyk-Kul region – Dzhety-Oguz and Ak-Suu by the interview of 217 local farmers, the vitamin content was determined by known methodic. The study showed that there are 4 varieties of pears, of which 3 are local / traditional; 8 varieties of apricot with 5 local and 26 varieties of apple with 21 local. More than half of the local varieties of pears, apples and apricots disappear at the present time due to different reasons (non-compliance with market requirements for long-distance storage and transportation of fruits, bacterial burn disease that affected 90% of all pear plantations, lack of planting material and of knowledge and skills for grafting, treatment for diseases without antibiotics, agrotechniques) and are actively replaced by new commercial varieties. Among 8 varieties of apple and pear there were no varietal differences in the content of vitamins, but all of cultivars were significantly inferior to wild berry shrubs - viburnum, barberry, and dog rose for the content of vitamins A, C, B3, β-carotene. Based on the results of the survey, were developed practical recommendations for farmers on preserving the diversity of local varieties of fruit trees and wild berry shrub.

Relevance. The main producers of cabbage in Dagestan are personal subsidiary farms of the Mountain subprovince. An additional reserve of production is the Foothill subprovince (in particular buinak district), soil and climatic conditions which are favorable for growing cabbage. In this regard, studies aimed at studying the adaptive potential of cabbage varieties in this subprovince are relevant.Material and methods. The aim of the work is to develop elements of technology for growing varieties of cabbage in relation to the Foothill sub-province of the Republic of Dagestan. The results of three-year studies on the adaptive potential of cabbage varieties in irrigation conditions of the Foothill sub-province of the Republic of Dagestan are presented.Results. As a result of the conducted researches it is revealed that the variety Nadezhda has formed the greatest productivity on all variants on a mode of irrigation. Quite high data are also noted in the variety Samur 2. Comparative analysis of variants of the experiment the total water consumption showed that, on average, for the studied varieties of cabbage most economical use observed in the irrigation regime providing for irrigation when pre-irrigation moisture threshold 75-85-75% NV. On average, the studied varieties and hybrids of cabbage, the most economical expenditure was observed in the irrigation regime, which provides for the appointment of watering at the pre-watering threshold 7585-75% NV. Compared with the first option (70-80-70% NV) saving irrigation water was 150 m3/ha, and compared with the third option (80-90-80% NV) – 178 m3/ha. On the same option was formed quite high productivity of varieties of cabbage.

Often in the soils of crop rotations of grain crops, including on black soil, the content of mobile forms of copper, manganese, zinc and other trace elements is low. Improving the efficiency of making micronutrients for grain crops and determining the best ways and doses of their introduction are topical issues that need to be addressed in order to increase the productivity of crops. The purpose of research is to identify the effectiveness of the use of water soluble compound fertilizer with microelements of the company “Haifa Chemicals” in the technology of growing winter wheat on leached chernozem under conditions of the Oryol Region. Field production experiments were established in 2017-2018 on the basis of Orlovsky Leader LLC Branch №5” located in Livensky district. Field experience with the use of Haifa Chemicals products: Poly-Feed micronutrients 19-19-19 + 1MgO + ME and Poly-Feed 6-15-38 + 3 + ME was laid on soft winter wheat varieties Moskovskaya-56.The control variant was the basic technological scheme used in the household for carrying out leaf dressings with mineral fertilizers together with the organic fertilizer Gumostim. As a result of the research, it has been established that the use of double foliar feeding water soluble compound fertilizer with microelements Poly-Feed 19-19-19 + 1MgO + ME in the tillering stage and at the end of flowering and a single Poly-Feed 6-15-38 + 3 + IU in the subflag phase - flag leaf, increases the height of the plants, as well as the productive characteristics of the ear: the size of the ear, the number of grains in the ear, the mass of grains and their best quality, which in general provides a reliable increase in the yield of grain of winter wheat. At the same time, it was found that, due to leaf feeding, the impact of adverse weather conditions under which the development of winter wheat plants took place in 2018 and their productive properties were laid was leveled out. Due to relatively low additional costs, the use of complex fertilizers of the Poly-Feed brand for winter wheat is economically feasible and can bring additional economic income: based on the maximum level of minimum prices for the grain of the 2018 harvest, it will be 2.07-2.28 thousand rubles / ha regarding base technology. Thus, water-soluble fertilizers, which include Poly-Feed company "Haifa Chemicals" are recommended to domestic agricultural producers for mass introduction in practice of the technology of intensive sheet nutrition of grain and other crops.
