Relevance Among vegetable crops, tomato is one of the leading places. In Siberia, tomato production is currently concentrated mainly in small farms and the individual sector. The problem of expanding the assortment of this culture in connection with constantly increasing market requirements remains always relevant. Material and methods The purpose of the work is the development of tomato seed production methods of varieties of selection of SibNIIRS. The studies were carried out in 2014-2018 at the experimental vegetable section of SibNIIRS - a branch of the ICG SB RAS. Results The results of many years of work on the study of seed and marketable productivity of zoned varieties and prospective tomato samples from the Urals andSiberia are presented. It has been established that in the conditions of a short growing season, high productivity is shown by varieties from early and mid-season groups. The highest sowing qualities are formed when sowing in time, optimal for the zone – the third decade of April. Early seeding shifts the phenological phases towards their rapid passage, but this creates unfavorable conditions for setting – stress during transplants, unfavorable weather. During late sowing, seeds are formed with low sowing qualities due to insufficient heat supply, especially for varieties from late ripeness groups. Germination energy and germination are higher in seeds obtained from fruits taken in the phase of full biological ripeness in all varieties. With long-term ripening (eat fruit in the phase of technical ripeness) there is a high risk of seed germination inside the fruit on the one hand and lack of nutrients, which invariably affects sowing qualities.

The effect of pre-sowing treatment by extract of seeds-donor of different concentrations on germination, seedling vigor, and yield of tomato was shown. The seeds of different varieties of winter wheat, barley, oats, alfalfa, soybean, and maize were used as a seedsdonor of biologically active substances. It was found that these substances increased the seed germination and improved the seed vigor, plant development and product quality. This technology can be considered as a source of increasing in labour productivity and seed production.

The experiment was conducted in the Maritsa Vegetable Crops Research Institute, Plovdiv during the period 2008-2009. Four garden pea varieties were grown in the conditions of organic and conventional production. The purpose of the experiment was to study the quantitative characters of seeds obtained in organic production. It was established that the organic garden pea seeds differ with lower absolute weight compared to the seeds obtained in conventional system but they kept high germination (89,5-96,5) close to the control variant. The late variety Vyatovo grown with organic fertilizers and biopesticides are with the lowest percentage of injuries by Bruchus pisi l.

Relevance. The use of biological preparations in agricultural technology of agricultural crops contributes to the preservation of agrophytocenosis, reduces environmental pollution and has a positive effect on the growth and development of the plants themselves. In this regard, the determination of the effectiveness of the use of biological products in the presowing treatment of common bean seeds is relevant and timely.Materials and methods. In our study, we studied the effect of presowing treatment of common bean seeds with biological products: Polydon Bio Profi, Polydon Amino Mix, Polydon Aminomix, Alfastim on germination energy, germination, seed sprout size, number of roots and length of the root system. Three varieties were taken as objects of study: Athlete, Omichka, Sirenevaya.Results. A different effect of preparations on the time of seed germination was revealed. The average germination time in options 1-4 was higher than the control values for all varieties, i.e. drugs slowed down germination. The seeds of the tested varieties responded positively to treatment with Alfastim (option 5): the average germination time in Fizkulturnitsa and Sirenevaya decreased by 8.5 and 9.8%, in the Omichka variety by 45%, compared with the control. Among the tested varieties, it is necessary to single out the Sirenevaya variety, which has the highest germination energy (ES) from 90% to 100% and seed germination (VS) from 98-100% in all treatment options. The most effective treatment of the Omichka variety was in option 2 (EP-90%, germination rate 90%), the values exceeded the control by 5%. For all options, the germination energy of the Fizkulturnitsa variety ranged from 72 to 90%, germination from 73 to 93%. A positive effect of drugs on the germination of seeds of this variety was established. The defeat of bean seeds by mold fungi was noted. Seed damage is mild to moderate. Seed damage by mold fungi in the variants using Polydon Bio Profi was absent, or it was weak up to 3.3% for all tested varieties. Morphobiometric indicators of seedlings and their root system in all varieties developed more effectively on variants with the use of Polydon Bio Profi and Alfastim preparations, and their mixtures

Relevance. Increasing the resistance of vegetable plants to unfavorable growing conditions with the use of growth regulators that actively affect the seed quality, increase the survival rate of seedlings, stimulate the setting, formation and maturation of the crop is a significant reserve for increasing productivity with the already achieved level of intensification of their production.Material and methods. The effect of verbascosides obtained by exhaustive extraction with 60% aqueous ethyl alcohol from the aboveground part of Verbascum densiflorum Bertol. (Scrophulariaceae) was studied on the germination, growth, development and yield of tomatoes, cucumbers, onions and white cabbage. Before sowing, the seeds were soaked in an aqueous solution of verbascosides for 15-20 minutes, followed by drying to flowability at the rate of 0.5-0.8 liters of solution per 1 kg of seeds.Results. It is shown, that possessing phytoregulatory activity and influencing the metabolic and synthetic reactions of plants, these compounds, applied exogenously, stimulate the seed germination energy and total germination of vegetable crops, provide simultaneous appearance of seedlings and optimal plant density, accelerate the growth dynamics of plants assimilation surface and fruit mass. Reducing the consequences of stresses arising in the process of plant growth and development, they thereby contribute to increasing plant resistance, productivity and improving the commercial quality of the products. The ability of these compounds to improve the production process of vegetable crops, depending on the type and variety of vegetables was established. Their highest stimulating effect was determined on cabbage variants, where the yield exceeded the control by 34.3%. The performed studies and obtained results allow to recommend the pre-sowing seed treatment with a 0.01% solution of biological active substances from Verbascum densiflorum Bertol. as an element in technology of growing vegetable.

Experiments were carried out at FGBNU VNIIO in 20112016. The aim of the study was to analyze the influence of different types of organic dormancy caused by various factors on seed quality of some representatives of umbellifer crops. The objects of the study were seeds: parsnip ‘Kulinar’ (Pastinaca sativa L.); carrot ‘Rogneda’ (Daucus carrota L.); root parsley ‘Ljubasha’ (Petroselinum crispum (Mill.) Nyman ex A.W. Hill.); root celery ‘Kupidon’ (Apium graveolens L.); coriander ‘Yantar’ (Coriandrum sativum L.) and dill ‘Kentavr’ (Anethum graveolens L.). In all seeds studied, the speed of embryo growth was decreased by 30% or0.03 mma day. Under influence of the induced dormancy caused by incubation in extract from dill seeds, the speed of embryo growth in all species was decreased by 94-97% on average. The process of germination of just picked seeds in all crops studied showed itself in reduction of germinated seed number by 54% as compared with control variant. Under the effect of incubation at high temperature the seeds of parsnip and root celery didn’t germinate, whereas the germination in the seeds of coriander, root parsley and carrot was decreased by 51%, 47% and 46%, respectively as compared with control. There is no germination observed in parsnip, carrot, root celery and coriander under influence of induced dormancy caused by incubation in extract from dill seeds. In this case, the germination of seeds of root parsley and dill was 8.1% and 15%, respectively. The Pearson correlation between the speed of embryo growth and percent of seed germination showed the significant and positive relationship in the range 0.706-0.952. Analysis of variance (ANOVA) showed that induced by temperature or allelopathic dormancy had impact on the speed of embryo’s growth in the crops studied, where factor effect was 89-86% depending on type of dormancy. Analysis of variance between the factors of dormancy and germination revealed that all types of dormancy analyzed had much influence on germination in these crops. The factor effects for primary, temperature induced, and induced allelopathic dormancy were 98% (F=1590.3; P=< 2x10-16), respectively.

Vegetable production in Dagestan is the one of the smallscale, where elementary techniques are used, therefore the vegetable commodity output does not reach a third from total volume produced. With appearance of new irrigation technologies the perspective occurred to raise the productivity of vegetable growing. The use of the drop irrigation improved the vegetable production and yield as well as carrot production. The influence of sowing terms and plant density on features in vegetation phases, photosynthesis activity and water consumption in drip irrigation was studied in carrot ‘Chantenay 2461’ grown on the meadowchestnut soils medium loamy soils of plain areas in Dagestan. Spring sowing time and summer sowing time with plant density of 0.6; 0.8 and 1.0 million plants per hectare have been studied in accordance with the two-factor experiment. In the course of experiment, it has been shown that not the plant density but sowing terms have essentially influenced upon interphase vegetation period in carrot. It has been also revealed that sowing terms have influenced upon photosynthetic activity, increasing the leaf area by 15.1%, while photosynthesis activety and dry matter content have increased by 7.5% and 4.2% respectively. The maximal parameters of photosynthetic activity were obtained when sowing in the second ten-day period of March with density of 0.8 million plants per hectare, and a yield of 42.2 t/ha. To produce such yield, there is a requirement of irrigation rate should be 2600-2700 m3/ha, on average with 18 watering at rates between 87-165 m3 /ha. Calculations of energy and economic efficiency have shown that when sown in the 2nd decade of March density of 0.8 million plants per hectare gave maximum energy efficiency 6.14, whereas the level of profitability of production expenses was equal to 73.5%.
