High Yields

One of the modern selection tasks in vegetable growing is quality products improving, obtaining high yields of environmentally safe wide assortment vegetables. To the new varieties of vegetable crops including winter white cabbage are specified new requirements such as market competitiveness, resistance to unfavorable environmental conditions, heat resistance of the varieties and F1 hybrids. The article is shown investigation results about studies of exogenous treatment by solutions on the base of physiologically active compounds of hormonal nature on the started process of stem extension stage activation and flowering of winter white cabbage plants. For the first time in the Dagestan conditions has been studied the possibility of hormonal regulation of the premature stem extension stage and flowering prevention of winter white cabbage after the initiation of natural induction. In our studies with an early planting there are not more than 20% of blooming plants, most varieties showed a high propensity to premature stem extension stage and flowering. The possibility of the hormonal exogenous regulation of the unfavorable winter white cabbage flowering has been revealed. The most pronounced effect on the transition to stem extension stage and flowering were provided by auxin nature preparations. In particular, treatment with NAS at a dose of 5 mg / l significantly reduced the number of blossom plants, krezatsin (50 mg / l) had a similar effect, but it was less pronounced. The use of cabbage in winter crops makes it possible to obtain two or three yields per year from the same area. Creation and introduction into production of promising and high-yielding varieties and hybrids will allow increasing production and reducing its cost.

In the conditions of covered crop in Dagestan tomato ranks the first in terms of cultivation area and in the country it is the second place after cucumber. However, tomato production has not yet reached the level necessary to meet people’s need. Growing it allows solving the problem of import substitution, ensures a constant supply of fresh vegetable products and solves the problem of a balanced, complete nutrition human nutrition throughout the year. When studying vegetable crops in covered crop conditions were revealed both general provisions characteristic of any region and specific features depending on the complex of local natural conditions. The level of radiation, temperature, humidity, wind and snow loads leave a certain influence on the growing tomatoes technology, which makes the problem of developing scientifically grounded elements of technologies for their production, ensuring high yields of vegetable plants and environmentally safe out-of-season products. With a wide variety of soil and climatic conditions in Dagestan, territories with extreme natural contrasts, even within a single agroclimatic region, the features of light and other microclimate regimes require clarification of the most important elements of agricultural technology. One of the main components of tomato growing technology is timely protection against diseases and pests. In the absence of a system of protective measures yield losses can reach 50% or more. In this context, the assessment of new F1 hybrids in film greenhouses in the winter-autumn circulation was carried out, the most promising of them for the conditions of Dagestan were identified, and the main elements of their cultivation were developed. The article presents the results of the dynamics of the yield of the crop by months. The influence of sowing and planting dates on the tomatoes yield is shown, the optimal scheme of sowing and planting tomatoes is determined. A phenological calendar for plant protection was compiled. The prospects of growing the studied hybrids in this region have been substantiated. Обоснована перспективность выращивания изучаемых гибридов в данном регионе.

Relevance. The success of breeding work is largely determined by the source material, the search and creation of which for target breeding begins with the collection and study of collectible samples for the alignment of morphological features; for the precocity and amity of maturation; for the keeping quality and transportability of bulbs; for the quality of vegetable products (high content of biologically active substances and antioxidants); for resistance to biotic and abiotic stressors of a specific growing zone.Materials and methods. On the basis of the North Caucasus branch FSBSI FSVC, 90 samples of spring onions from 26 countries of the world were evaluated in the number nursery for the period from 2017 to 2019, 71 of them were varieties and 19 were F1 hybrids. In a hybrid nursery, 25 hybrid combinations obtained from FSBSI FSVC (VNIISSOK) were evaluated. The laying and placement of experiments, agricultural techniques of cultivation, accounting and evaluation of economically valuable traits, biochemical analyses were carried out according to generally accepted methods. The standards are the new Primo and Ampex varieties of the selection of the FSBSI FSVC and the Italian F1 hybrid Ranko, which were placed every 10 collection samples.Results.According to the results of the assessment, among the studied F1 varieties and hybrids, sources of economically valuable traits such as yield (20-27 t/ha), precocity (80-90 days), preservation (more than 85%) when laid for long-term storage up to 7 months, purple, white and pink color of bulbs, as well as sources of long-shaped bulbs were identified. The greatest interest for breeding for yield is represented by 9 promising varieties and 9 F1 hybrids of onions of various origins, as well as 4 hybrid combinations that were distinguished by high yields, the yield of marketable products and the mass of marketable bulbs. These samples are recommended for use in the breeding process as sources for the creation of new varieties and hybrids with high yields for the agro-climatic conditions of the foothill zone of the North Caucasus.r breeding

Relevance. The most complex and common physiological disease on the cabbage is a tip burn, associated with impaired Ca2 + transport inside the plant. Of all the ways to control this physiological disease, the most effective is the cultivation of tolerant hybrids. Material and methods.The aim of the research was to evaluate the mid-late and late ripening F1 hybrids of white cabbage for a tip burn and to determine the degree of hybrids responsiveness to calcium deficiency depending on weather conditions. The studies were carried out at breeding and experimental plot of the vegetable growing department at All-Russian Rice Research Institute in 2017-2019 on drip irrigation. Material - hybrid combinations of ARRRI breeding.Results. The manifestation of a physiological disturbance called “burn of the top of the inner leaves of the cabbage head” or “tip burn” on individual hybrids was observed during all years of cultivation, but to a different degree; The greatest damage to the heads was recorded in the years (2017 and 2019) with high productivity, which is due to the intensive assimilation ability against the background of warm sunny weather. In 2019, the manifestation of burns was noted in 25% of hybrids, which allowed them to be divided into 4 groups, depending on the degree of damage and the spread of the disease.It was established that hybrids with overmature standing for 2.5-3 weeks and also hybrids that were promptly removed at the time of mass technical ripeness had a high degree of damage. The lines that are most often found in hybrid combinations with signs of burns (269-824, Agr1321, 269Jas13, Byum112, Yas25, etc.) were identified, but it is rather difficult to assume the nature of inheritance, and, therefore, to develop the principle of pair selection when developing relatively stable hybrids also not yet possible.

The food problem has been and has remained relevant throughout the history of mankind. At the end of 20th and the beginning of the 21st century, in the lives of many nations and countries, there have been significant changes. Health status and level of education of the population, such as, for example, food security, is the priority in many countries since, in the absence of sufficient food reserves, there is an economic and political dependence of some countries on others. Having not yet received the required amount of food, the world is faced with the problem of ensuring security in its quality. Anthropogenic pollution of the environment complicates the problem with the quality of food and the exception of harmful chemicals in food. There is a problem of using environmentally friendly agrotechnical means, ensuring the production of high yields of environmentally safe products with a desirable reduction in their cost, and shortening the time required for their production.

ABSTRACT The aim of this study was to obtain new broccoli lines with cytoplasmic male sterility trait for the development of the modern F1 hybrids. CDT70 cauliflower line obtained in the Research Institute of Horticulture, formerly Research Institute of Vegetable Crops, Skierniewice, Poland, with the reliable cytoplasmic male sterility from Raphanus sativus (Ogu-INRA) was selected as a source of this trait. Three broccoli lines: BMi, BCr1 and BCr2 were used as donors of commercial characters in all cross combinations with sterile components. Selected fertile broccoli genotypes were characterized by good quality, uniformity and high level of self-compatibility. The breeding procedure included three consecutive back crosses of male sterile genotypes with fertile broccoli lines that lasted from 2008 to 2012. In each generation, self-compatibility level, the stability of the male sterility trait and ability for the generative propagation of back-crossed genotypes were tested in comparison with donor broccoli lines in the greenhouse. The agronomical and morphological characters of the back-crossed progeny were also evaluated in the field. As a result, three CMS broccoli lines of Bc3 generation with good quality and high seeding index, suitable for the breeding purposes, were obtained.

Cabbage Pests

The animal world of Ukraine is characterized by a large variety of species. Among the lepidoptera there are a lot of pests whose larvae cause significant damage to agriculture. In the paper, we investigated the seasonal and perennial dynamics of vegetable crops pests’ population of Mamestra brassicae in the agrobiocenoses of white cabbage. The basis of our study was the investigation of the relative quantity of the pest larvae, we demonstrated the damage to plants, as well as the periods of intensive emergence of the imago and the number of generations per year. In future, this will enable the development of effective ecologically sound methods for controlling the number of species of white cabbage pests in the conditions of Kamin-Kashyrskyi district of Volyn region. Kamin-Kashyrskyi area has a flat terrain and is characterized by a warm temperate continental climate with sufficient amount of moisture, the presence of impoverished sod-podzolic soils. The area is mostly plain, with large marsh massifs, which are favorable conditions for the existence of Mamestra brassicae, as this species is moisture-loving. Observation of biocenotic connections in the agrobiocenoses of white cabbage and stationary research on the development of protection, testing and implementation systems was carried out during 2017-2018 at the garden sites of Kamin-Kashirsky district during the entire vegetation period of the plants. White cabbage is damaged throughout the period of vegetation, however, the damage that appear after emergence of seedlings and planting of seedlings into the soil are dangerous due to their consequences. In the second half of summer and in autumn, the larvae of Mamestra brassicae caused significant damage to cabbage plants in the gardens of Novi Chervyshcha. Within this area, Mamestra brassicae develops two generations per year, causing tangible damage to the agrocoenosis of cabbage of different sowing dates. The contamination of cabbage by the larva of the first and second generations approximately accounts to 24%, where 2-3 larvae live on one plant. The massive emergence of the imago occurs in the middle of May the first half of June while the average daily temperature is +20°С to +22°С. The first egg laying was recorded at the end of May, which the female lays in groups, 20-80 units on the underside of the leaves, and the embryonic development lasts 6 to 8 days. Pupae hibernate in the soil, at a depth of 8-12 cm. Significant damage to white cabbage plants was caused by the larvae of the first generation in June and early July, and of the second generation in August and early September. They intensively feed at night and at dawn, and in the daytime there is a decline in mobility and nutritional activity. Second-generation larvae often bite into cabbage heads where they make holes and pollute them with their liquid excrement, which leads to a decrease in crops. The use of microbiological drugs Dimilin and Insehar are some of the most effective ways to get rid of Lepidoptera, including larvae of Mamestra brassicae, which provide protection of cabbage plants by 93-97%.

The aim of present investigation was the assessment of the several new onion hybrids develop through three- way cross along with their parents for having less problem of weight losses due to sprouting and rotting, and long storage quality at normal room temperature and relative humidity. The design of experimental plot was complete randomized block design (CRBD) with three replications. This study was carried out in the year of 2018-2019 at Division of Vegetable Crops, ICAR-Indian Institute of Horticultural Research, Hessaraghatta, Bengaluru, India. Thirty hybrids developed by three- way cross, thirteen parental lines and one check have been included for the experiment. Three F1 hybrids used as female lines and ten commercial varieties used as male testers, were taken to develop the hybrids through line x tester design. The bulbs of all these genotypes were kept for four months in normal storage chamber at 25-30°C room temperature with 65-70% relative humidity. The overall losses of per cent bulb weigh was recorded and conclude that the three-way hybrids TWCHO-15 (26.91) were recorded for smallest amount of loss followed by TWCHO-5 (27.02), TWCHO-14 (28.83) and TWCHO-4 (29.98). These hybrids can be suggested for more profit to onion grower by keeping for long shelf-life.

Garden pea is one of the economically and nutritionally most important winter vegetable crops in Nepal. Garden pea production is an emerging farm enterprise of Nepalese farmers of Eastern hill and mountain. The study was conducted to determine profitability, to investigate whether factors of production are being used in economic way, and to find out extension strategies for increasing income of farmers in Dhankuta district of Eastern Nepal. A total of 120 garden pea producing farmers, (60 from Chhathar-Jorpati Rural Municipality and 60 from Mahalaxmi Municipality of Dhankuta), were randomly selected and interviewed using semistructured interview schedule. Descriptive statistics and Cobb-Douglas production function were used to analyze the collected data. The benefit cost ratio (3.54) indicates that the garden pea production in study site was profitable with productivity of 6.59 Mt ha-1 per hectare. The production function revealed that cost on seed and labor have statistically significant effect on gross returns. In contrast, the effect of cost cost on plant nutrients and pesticides were not statistically significant. The sum of regression coefficients was 1.04 which indicates that production function exhibited an increasing return to scale. Thus, extension strategies should be primarily focused on introducing high yielding varieties, use of high quality seeds, providing trainings on improved farming practices, increasing value addition practices and strengthening market infrastructures.

The article deals with the study of the effect of the application of the herbicide Granstar Gold 75, w.g. (water-soluble granulate) and plant growth regulator Regoplant on some ecological indicators of ecocenosis of winter wheat sowing (lipid peroxidation reactions in winter wheat plants by the activity of malonic dialdehyde content accumulation, enzymatic activity, total number of rhizosphere bacteria and anatomical structure of winter wheat leaves). The choice of research topic is due to the fact that currently obtaining high yields of winter wheat is closely connected to the widespread use of chemicals, in particular, herbicides, which by their nature are physiologically active substances that can affect both plants and soil microbiota. This, in turn, leads to the search for environmentally safe elements of technologies for growing winter wheat. One such element may be the use of herbicides together with plant growth regulators. The obtained experimental data testify to the protective ability of the growth regulator Regoplant against the winter wheat plants, as evidenced by a decrease in the activity of malonic dialdehyde accumulation, changes in the activity of the enzymatic defense system, decrease the number of epidermis cells and an increase in total rhizosphere bacteria in case of Regoplant use together with Granstar Gold 75, w.g. compared with the experiment variants, where the herbicide was applied without a growth regulator. That is, the use of growth regulator in a mixture with herbicide to some extent eliminates the toxic effect of xenobiotics, which has a positive effect on the state of ecobiosis of winter wheat sowing.
