Vegetables are considered essential for well-balanced diets since they supply vitamins, minerals, dietary fiber, and chemicals. Thechilli pepper fruits (Capsicum spp.), like many other vegetable crops, are a source of important biological components – the macro-, microelements and antioxidants. In this regard, the chilli pepper can be included in the category of dietetic foods.The most cultivated in Russia chilli pepper varieties belong to the Capsicum annuum L. At present, in the world and in Russia huge number of varieties are selected, with different color, shape and hot and pungent taste of the fruits with a high content of carotenoids, capsaicinoids and ascorbic acid. These varieties belong to the species C. chinense, C. frutescens, C. baccatum and C. pubescens. The fruits of these forms and products of their processing are suitable for industrial applications and are the basis of many sauces, pastes, ketchups, and ingredients, which is used in food, pharmaceutical, confectionery, alcoholic beverage, military and other industries. Chilli peppers, in addition to nutritional value, are ideal for ornamental horticulture, because of the compactness or vice versa weeping form of the stems, suspended like bells and differently colored like a rainbow, fruits, colorful combinations color of leaves and fruits. You can use them and direct planting in the ground, and as a potting culture in balconies, loggias, winter gardens, in combination with other plants.

Vegetable root plants are valuable, irreplaceable components of a rational food of the person. In the assortment structure of the vegetable market table roots occupy 24%. This article presents a new assortment of vegetable roots selection VNIISSOK over the past decade, the characteristics and advantages compared to foreign varieties and hybrids F1; new linear source material for breeding for heterosis carrots, beets, radishes; identified areas of selection in the future, taking into account market requirements.

The possibility of using small-sized greenhouses for growing seed plants is shown, which increases seed productivity almost twice, compared to open ground, provides reliable spatial isolation. The substantiation of the use of new, more advanced machines and mechanisms for the improvement of seed heap and seed pretreatment is given, which significantly increases the sowing quality.

The purpose of the research was to study and optimize the timing of growing tomatoes in conditions of transitional turnover, taking into account the natural and climatic conditions of Dagestan, biological features of culture, lighting conditions, market demand for vegetable products, profitability of production. Experimental studies were carried out in 2015-2016 in the greenhouse farm "Niva". The technology of tomato cultivation in winter and film greenhouses in the transitional turnover of the 6th and 7th light zone of the country is shown, its economic efficiency is shown in the light conditions of Dagestan. The studied F1 hybrids were distinguished by a good harvest yield from December to April, the highest yields were scored by hybrids: Tomimaru Mucho F1, Pink Paradise F1, providing 15.68 and 14.98 kg. The economic evaluation of the studied hybrids and varieties of tomato showed that during planting sowing and planting cannot be delayed, since plants fall into conditions of limited illumination by young ones that have not yet entered the phase of mass fruiting, and the harvest in the winter months is sharply reduced, profitability decreases. According to the average market price for the sale of tomato fruits in the winter months of 200 and 210 rubles per kg, depending on the timing of harvesting and marketing, the profitability of production of hybrids was in %%: Tomimaru Mucho F1 – 120-170, Tiwai F1 – 125-170, Pink Paradise F1 – 123-174, Revermun F1 – 90-110, Lvovich F1 – 123-159. Such profitability of cultivation of the studied varieties indicates that their growing in the transitional turnover is economically profitable.

The effects of different fertilizer rates, irrigation, sowing rate for carrot and red beet were studied in the field condition in food-hills zone of Chechen Republic. The use of N40-80P40-80K40-80 caused the increase in yield from 22.8 to 30.8-33.2 t/ha or by 35-46%, when cultivating a carrot crop. Under irrigation the yield increases by 30-33%. Application of N40P40K40 and maintenance of soil moisture at 70% of moisture rate provoked the improvement in value, market and biochemical characteristics of roots; where the increased contents of dry matter, total sugar and vitamins were observed. The mathematical modeling for the process of yielding abilities and root quality in carrot and red beet showed that highest productivity can be achieved on chernozem soil at Central Pre-Caucasus zone when the level of mineral plant nutrition was N40-60P40-60K40-60. The further increment in fertilizer doses does not bring an improvement to yields and leads to decrease in quality of yields. The increased level of antecedent soil water moisture 70-75% of moisture rates does not raise the yield, on the contrary decreasing at the same time the root quality. The use of mathematical modeling enables to rationally define the fertilizer rates depending on application of irrigation and sowing rates in cultivation of carrot and red beet.

The purpose of this work performed in 2015-2017 on seedgrowing crops of the Crimean OSS VIR was receiving hybrid seeds of a vegetable marrow at free pollination and check of their quality by method of soil control. At laying of seed-growing crops, carrying out variety cleanings,, inspections and approbation were guided by the Instruction for approbation of seedgrowing crops of vegetable, melon cultures, fodder root crops and fodder cabbage (2008). The vegetable marrow with a high saturation pistillate flowers of Bl12, Su4 and Ar3 were used as maternal lines. Double processing by solution of an etrel was carried out to early phases of development of plants them. Use of this growth regulator has influenced blossoming of plants - in the lower knots men's flowers weren't formed, purely women's blossoming for the term of 14-17 days, sufficient for setting of seed fruits was observed. Control of blossoming of maternal forms was exercised by systematic inspections of plants on a floor. We have conducted three multiple examination. The first - before blossoming of maternal plants, in a budding phase when it is already possible to distinguish a sex of flowers, the second – in a phase of the beginning of blossoming. The third examination was conducted for definition of the beginning of blossoming of male flowers on plants of the maternal line. Timely carrying out inspections and variety cleanings, promotes receiving qualitative hybrid material. When carrying out soil control the high hybridism of seed material is revealed: F1 Bl12 x D1 - 95,3 %; F1 Su4 x D1 - 95,7 %; F1 Ar3 x D1 - 96,0 %. The results indicate that of the carried-out work, at free pollination of maternal and fatherly forms, vegetable marrow seeds with a high hybridism are received. Conducting the trial testing of new hybrids showed their high economic value. In comparison with the standard of Belogor F1, their total yield is higher by 16.7-25.7%, and the early yield by 10.5-27.7%. The introduction of new vegetable marrow hybrids in production is cost-effective and in demand.

The genus Cucumis L. is polymorphic, includes annual and perennial species, distinguished by the type of flowering, ploidy, and resistance to diseases. C. sativus L. (cucumber) and C. melo L. (melon) are widely known species of the genus Cucumis L. Species of the genus Cucumis L. in their distribution are adapted to the diversity of habitats, are characterized by different level of adaptation to biotic and abiotic stress factors. Interspecific hybridization is an important method of enriching the gene pool of cultivated plants allowing to transfer of valuable characters from wild to cultural species. Clarification of the level of species crossability and the viability of the hybrids is an important factor in creating a valuable initial material for breeding. The prospects of using interspecific hybridization in breeding are shown, including the transfer of resistance to harmful diseases to cultural species. Morphological and biological characters of the species of the genus Cucumis L. and the level of their crossability are described. For practical use, the most interesting species are C. africanus L, C. aculeatus Cogn. and C. anguria L., whose compatibility level reaches 4.0%; they are characterized by heat and drought tolerance and resistance to a number of diseases. However, crossing species of the genus Cucumis L. is not always successful. The main reason is the phylogenetic distance of species, the differences in the number of chromosomes, as well as living form, etc. The use of modern breeding genetic methods of research to overcome the noncrosslinking of different species will facilitate the discovery and use of their biological potential.

Presents comparative characteristics of the 4 new varieties of melon breeding Bykovskaya melon experiment station in comparison with the standard. A brief description and varietal characteristics of the new varieties of melons of different ripening periods. Data on the yield, length of vegetation period, dry matter content, as well as complex resistance to diseases. According to the results of comparative evaluation in station variety testing, new melon varieties exceed the standard in yield from 2.7 t/ha (Harmony) to 4.6 t/ha (Originalnaya x Osen), in dry matter content from 0.2% Cometa variety to 1.1% Harmony variety (standard Osen variety – 13.0%). Testing for complex resistance to Anthracnose and powdery mildew revealed that the lowest degree of damage in a hybrid combination of the Originalnaya x Osen was powdery mildew – 51.3%, with a score of 1.4, anthracnose – 80.6% at a score of 1.5.

Potato and table beet are traditional crops in vegetable growing in Russia. It is important to produce high, environmentally friendly crops. The effect of mineral fertilizers to reduce the accumulation of heavy metals (HM) in beetroot and potatoes was studied in the experiment on ordinary chernozem. The soil was supplied with Cu, Zn and Pb, as a mineral fertilizer, Azofosca (N16%, P16%, K16%) was also used in the experiment. Salts of heavy metals and fertilizer were introduced in accordance with the developed scheme of experiment: 1. Control; 2. Cu100Zn100Pb100; 3. N60P60K60 + Cu100Zn100Pb100. In the soil, the total stock of metals and their mobile forms were determined, and the content of metals and yield were defined in plants. The results of the study showed that for gross forms MRL exceeded in all metals studied, and in mobile forms of Cu and Pb. With the joint application of HM to the soil with fertilizer, the mobility of metals decreased. In the root crops, the excess of MRL for Cu, Zn and Pb was observed. With the joint application of HM with fertilizers, the content of Zn and Pb in the root crops decreased below the MRL. Beet was more likely to accumulate HM than potatoes. The yield of beetroot and potato beets varied greatly in terms of experiment options. Thus, the introduction of HM into the soil significantly reduced the yield of beets. The introduction of fertilizers together with HM contributed to an increase in yield, but for beet, the yield level here was also lower than in the control variant. When growing roots in technogenically transformed conditions, the potato is characterized by sufficiently higher yield stability and does not accumulate toxic amounts of HM on a fertilized ground.

The fundamental direction of modern agriculture development is elaboration and utilization of technologies that ensure environmental safety, high plant productivity and quality of crop production. In this connection, the issues of optimization of mineral nutrition and water supply, immunity enhancement and protection of plants against various forms of biotic and abiotic stresses without significant environmental stress are of current interest. Normal growth and development of almost all plants on the Earth depends on the presence of mycorrhizal fungi in the soil, which ensure optimal plant nutrition and water supply due to the huge number of hyphae. The review discusses the prospects for the use of arbuscular mycorrhizal fungi in the cultivation of Allium species, as the most responsive plants to the effects of mycorrhizae due to the poorly developed root system that hinders the nutrition of plants. It is noted that utilization of arbuscular mycorrhizal fungi may provide the reduction of the amount of fertilizers, herbicides and insecticides needed for high productivity of crops. The review deals with the peculiarities of symbiotic interrelations of different species of mycorrhizal fungi (pure and mixed cultures, mainly of the genus Glomus) with different Allium species (onion, garlic, shallot, leek, A. roylei, A. fistulosum, A. galanthum). Questions of agricultural crops quality as affected by arbuscular mycorrhizal fungy are discussed. Data on the effect of climatic conditions on the efficiency of arbuscular mycorrhizal fungi utilization in Allium production are discussed. The possibility of increasing the efficiency of biofortification of Allium species with selenium via utilization of arbuscular-mycorrhizal fungi is noted, as well as an increase in the content of biologically active sulfur-containing compounds in garlic. Particular attention is paid to the necessity of the development of arbuscular mycorrhizal fungi preparations in Russia – the country not using this ecologically friendly technology at present.

Production of functional food with significant antioxidant and anti-carcinogen activity is considered to be extremely significant in conditions of global ecological crisis. Among Allium species, wild garlic (Allium ursinum L.) along with the ordinary garlic are known to be the leaders in accumulation of natural antioxidants and sulfur-containing compounds with strong anti-carcinogen activity. Taking into consideration that Allium species belong to a group of natural accumulators of selenium, foliar biofortification of wild garlic with sodium selenate was achieved in Gudermes region of the Chechen republic. It was demonstrated that fortification of plants with selenium resulted in significant increase of chlorophyll a and b as well as carotene content, and two-fold increase of both polyphenol concentration and total antioxidant activity. Total dose of 2 mg Na2Se04 per square meter provided 14.4-fold increase of selenium content in A. ursinum leaves. Biofortification of plants with selenium resulted in 1.36, 1.28 and 1.38-fold increase of Cr, Fe and V concentration in leaves compared to leaves of non fortified plants. Leaves of A. ursinum fortified with selenium showed anomalously low Si content compared to non fortified plants. Compared to A. ursinum grown in Moscow region, wild garlic of the Chechen republic accumulated 2-fold lower levels of dry matter and 4.8-fold higher levels of monosaccharides. Compared to non fortified garlic leaves, those of A. ursinum demonstrated significantly higher levels of Cu, Fe, Mg и Zn. The results obtained suggest that A. ursinum fortified with selenium may be considered as a new functional food with strong antioxidant activity.
