The vegetable production is one of the main factors for food security, as vegetables play an important role in the structure of nutrition. The Federal Scientific Vegetable Center creates competitive varieties and hybrids of vegetable crops that meet market requirements to meet the needs of domestic producers and thereby contributes to food security. As a result of national breeding program, the varieties and hybrids adapted to different growing conditions, with resistance to local races of pathogens, temperature stresses, and ground frosts were developed to provide the sustainable production of vegetables with high nutritional and medicinal qualities. The varieties and hybrids F1 of white head cabbage that have been created for the last 5 years are distinguished from foreign ones by taste qualities, appropriate pickling characteristics with increased sugar, and decreased cellulose contents. The local onion varieties combine long shelf life, early maturing, well bulb formation, high dry matter content (18-20%) and ability to form the bulb for one year. Breeders have developed bee-pollinated and parthenocarpic hybrids of cucumber well adapted to local growing conditions and suitable for open field cultivation in different regions of Russia. Parthenocarpic heterotic hybrids of the multi-propose use, corresponding to the modern variety model with high productivity, early-ripening, bunch ovary disposition, resistance to abiotic stresses, and most harmful diseases. The carrot and red beet varieties with high nutritional qualities, long shelf-life, ecological plasticity that are widely used for seed production have been created. The varieties of Solanaceae crops have been developed to cultivate in Non Chernozem zone, Far East, Western Siberia, the Middle Belt of Russia and the south of Russia, are also suitable for different greenhouse complexes located in different light zones of the Russia. Wide application of varieties produced through national vegetable breeding programs can provide the population with our own products of high quality.

Growing Conditions

When growing herbaceous vegetable crops in the world practice, great importance is given to the use of grafting method. The development of environmentally safe methods to increase the yield and resistance of plants to adverse growing conditions is very relevant in vegetable production. One such method in pumpkin crops is grafting. The aim of our work was to study the effect of domestic pumpkin rootstock on growth, development and yield characteristics of cucumber hybrid using grafting method. Grafting on pumpkin species improved the growth and development of plants depending on the rootstock, compared with rootstock plants. The aim of our research was to study the influence of domestic pumpkin rootstock on the growth, development and yield characteristics of the cucumber hybrid (scion). As a scion, the variety (Asylum), recommended for cultivation in protected ground conditions, was used, which was grafted on five domestic rootstocks: 1 (Mozoleevskaya 10), 2 (Karina), 3 (Aphrodite), 4 (Mindalnaya) and Russian selection 5 (Stofuntovaya) pumpkins from vegetable and melon crops. According to the generally accepted method, the graft was grafted (cucumber Asylum) on the rootstocks of pumpkin. Using a sample of pumpkin 1 (Mozoleevskaya 10), flowering began on the fifth day earlier in comparison with non-grafted plants, and when grafting on a sample of pumpkin 4 (Aphrodite), the fruit ripened earlier by six days. To get the greatest increase in early productivity by 30%, it is possible to use both rootstocks. A significant increase in total yield was provided by samples of rootstocks 2 (Karina) – 3.9 kg/m2 and 3 (Stofuntovaya) - 8.0 kg/m2. The grafted cucumber plants with all the rootstocks used were superior to the root ones in height, in terms of the percentage of marketability of fruits and in terms of fruit weight. At the beginning of fruiting on grafted cucumber plants, the number of female flowers increased depending on the sample. In all grafted plants, the dry matter content in the fruit increased significantly. Because of our research, rootstocks 2 (Karina) and 3 (Stofuntovaya) were noted, which are recommended for use in further research breeding work and the production of grafted plants.

Nutritional Benefits

The search for forages with high biomass production and high nutritional content has made it possible to find food alternatives that, due to their nutritional benefits and resistance to adverse environmental factors, are the best option for herbivores. With the knowledge of farmers, producers and the experience of researchers, 12 species most frequently used in animal feeding were selected, identified and classified in the University's PSO herbarium of the University of Nariño. These were phenologically, nutritionally and antinutritionally characterized. Of these species, four belonged to the Asteraceae family; the Fabaceae, Adoxaceae and Malvaceae families were represented by two species; the Salicaceae and Cucurbitaceae families were represented by one and were propagated in nursery. In the nutritional composition, the Retamo (Genista monspessulana) stood out for its high dry matter content with 34.2%. Unlike the Chauchilla (Cyclanthera brachystachya), with 8.79%, the Sauco (Sambucus peruviana) had a higher content of protein 25.93%, followed by Abutilon (Abutilon pictum) with 23.42%. Chauchilla (Cyclanthera brachystachya) had the highest crude fiber content, with 21.59%, NDF of 38.06%, and FDA 27.23%. Tannins were the most common secondary metabolites in the species evaluated with moderate or low levels; sterols were present at low levels, and saponins and alkaloids yielded negative values.

SUMMARYAs a result of the treatment of made whole-crop barley silage with antimicrobial agents which are specifically inhibitory to fungi or bacteria, it was shown that the subsequent aerobic deterioration was essentially caused by yeasts. These microorganisms were instrumental in the rise in pH, the increase in temperature and the loss of dry matter observed. The filamentous fungi, like one group of bacteria (the streptomycetes), apparently had no part in the process. Bacteria, such as the lactobacilli and particularly proteolytic bacteria, may have had a role in the terminal stages of deterioration, although it was considered more likely that the yeasts again were involved.The whole-crop wheat silage employed in this work was stable in air, a factor attributed to the combined antimicrobial effects of butyric acid present and the relatively high dry-matter content.

Fertilization Rates

Organic production is one of the fastest growing food sectors globally. However, average yield in organic vegetable production is up to 33% lower than in conventional production. This difference could be due to higher fertilization rates in conventional, compared to organic, farming. We aimed to compare yield and quality characteristics of carrots produced under equal nitrogen fertilization rates over four years in organic and conventional conditions. We found a 14.5% higher marketable, and 10.0% lower discarded, yield in the organic compared to the average conventional treatments. In addition, carrots managed organically had 14.1% lower nitrate and 10.0% higher vitamin C content than carrots managed conventionally. There were no convincing effects of cultivation system on the nitrogen, total sugar, or dry matter content of carrots. Organically managed carrots were free of pesticide residues, while several residues were found in carrots managed conventionally. Our study reveals that organic management of carrots may exceed that of conventional methods in yield and several quality characteristics, while being free of pesticide residues. Organic fertilizer gave an advantage over mineral fertilizer, when equal rates of nitrogen were used in both production systems.

1. Polyethylene glycol (PEG) of high molecular weight, used as a dietary marker, did not distribute uniformly in the water present in a high-casein diet as did glucose, a low-molecular-weight substance.2. This distribution effect also occurred with the contents of the stomach and, to a smaller extent, with the contents of the first quarter of the small intestine of piglets given such a diet.
