The article presents the results of studying the winter garlic collection according to a complex of traits in the conditions of the Kirov region in order to identify for the breeding process promising forms with high productivity, good biochemical composition, suitability for mechanized sowing. During the study, planting with bulblets was used as the most common method of reproduction. In 2019-2020, fifteen varietal samples of winter garlic of different ecological and geographical origin adapted to local growing conditions were studied. Overwintering of all samples was 100 %. Varietal samples No. 154, 96, 116, 136, 155 and the standard variety Lyubov are suitable for mechanized sowing (clove weight is 5 g or more). According to the yield relative to the Lyubov standard variety (0.82 kg/m2 ), variety sample No. 115 stood out (1.02 kg/m2 ), LSD 05 = 0.16 kg/m2 . The maximum height of a scape of 122.5 cm was noted in the Kirovsky variety. According to the size of the bulblets, varietal samples No. 135 and 140, having 0.15 g weight of 1 bulbet were distinguished. According to the biochemical composition, the following varietal samples were selected: No. 155 having a combination of an increased content of dry matter (46.24 %) and sugar (15.82 %); No. 135 having a high content of ascorbic acid (13.20 mg%). The sample No. 154 also had a complex of valuable traits: the maturation 12 days earlier relative to the control and other samples; the highest leaf length and width (51.9 and 2.3 cm, respectively); the largest number of scapes (6 pieces); a high yield of 0.94 kg/m2 (at the control level); a maximum average clove weight (7 g).

Cruciferae (Brassicaceae) is one of the most important metasperms. Kale Brassica includes economically important vegetable, forage, oil-bearing, ornamental crops and it is widespread in the world. This is explained by variety of food organs, high yield, environmental plasticity, different ways of food use and valuable biochemical composition. One of the most important ways to improve the efficiency of vegetables is seen as increasing the number of cultivated vegetables and their varietal diversity. The authors speak about necessity to breed new varieties and hybrids of cabbage crops, not represented in the state register, as well as missing types of varieties in order to expand the range of vegetables. The paper points out that cultivation in the Asian part of Russia requires the varieties and hybrids of all cabbage crops that combine high productivity and complex resistance to biotic and abiotic stressors, eco-friendly, high-quality, with a different period of vegetation, including for horticultural use. The authors focus on increasing the nutritional value of vegetables and higher number of biologically active matters for making functional products. It is important and necessary to search within each cabbage for forms that combine productivity, resistance to biotic and abiotic factors when being grown in different environmental and geographical areas with a valuable biochemical composition. This allows to use efficiently cultivated and recommended for cultivation in the Asian part of Russia types and forms of Brassica L. vegetables. It is necessary for dietetic nutrition and raw materials in medical industry. All varieties of cabbage plants are supposed to be significant and reliable basis for improving population health and life expectancy taking into account existing environmental problems in the regions of Asian Russia.

The improvement of grain production is the most important global task. The introduction of new highly productive varieties of the leading grain crop, winter wheat, plays a huge role in its solution. The paper presents the study results of 80 winter soft wheat varieties of various ecological and geographical origin. Frost and winter resistance rise of the developed winter soft wheat genotypes today and in the nearest future is one of the main directions of breeding work. The preservation of highly productive winter soft wheat varieties varied from 0.0% to 78.3% at a freezing temperature of –19 °C. The varieties “Kaprizulya”, “Lilit”, “Zhavoronok”, “Lydia”, “Krasa Dona”, “Polina”, “Volnitsa” and “Volny Don”, developed in the Agricultural Research Center “Donskoy” have the highest frost resistance among the studied samples, they preserved 57.0 ... 78.3% of living plants. Grain productivity of the samples ranged from 6.36 to 8.90 t/ha in 2015–2017. The 16 out of 80 studied varieties reliably (НСР05 = 0.64 t/ha) exceeded the standard variety “Don 107” for this trait. Productivity of the best samples ranged from 8.14 t/ha (“СО 911”) to 8.90 t / ha (“Laureat”). The biological productivity of winter soft wheat varieties varied from 8.37 to 9.07 t/ha, exceeding the standard variety from 0.67 t/ha (“СО 911”) to 1.37 t/ha (“Laureat”). It should be noted that the correlation coefficient of actual and biological productivity was 0.84±0.06. As a result of the current study, there were identified the genotypes “Lydia”, “Volnitsa” and “Zhavoronok” combining high productivity, grain quality and resistance to low negative temperatures.

Positive Effect

The research reveals a versatile positive effect of organic bio stimulants Regoplant, Stimpo, and Emochka on kohlrabi cabbage plants. Soaking the seeds for 12 hours and foliar dressing of plants during vegetation with solutions of growth regulators contributed not only to increase the total yield of stems but also to enhancing growth indices of kohlrabi plants and at the same time ensuring better resistance to adverse growing conditions. The highest yield was obtained for the soaking seeds for 12 hours and 2 foliar dressings. Thus, in kohlrabi varieties ‘Delikatesna Bila’ and ‘Violeta’, the highest yield of stems (23.9?25.2 t/ha) was obtained under the influence of growth regulators Regoplant and Stimpo. In the experiment, a high yield of commodity stems was obtained in variety ‘Delikatesna Bila’ (86?93%) and in variety ‘Violeta’ (86?91%), which was on average higher by 8.0 and 5.6% than in the control treatment. The use of biostimulants ensured the yield of soluble dry matter higher by 0.2%, 0.4%, 0.8%in‘Delikatesna Bila’ and by 0.8%, 1.0%, 0.3% in ‘Violeta’, respectively, compared to the control treatment

Roots and shoots from seedlings of 29 coffee genotypes were studied to better characterize the entries from the Coffea germplasm bank of the Instituto Agronômico (IAC), Campinas, State of São Paulo, Brasil. The varieties were seeded in a randomized complete block design with 6 replications and 10 plants per plot. The characters evaluated were: plant (PL), shoot (SL) and root (RL) length; total plant (PDM), shoot (SDM), root (RDM) and lateral root (LRDM) dry matter. A lateral root index (LRI) and shoot root dry matter (SRDM = SDM/RDM) and length ratios; (SRL = SL/RL) were calculated. The dwarf varieties (Catuaí, Icatu-caturra, Vila Sarchi, San Ramon, Vila Lobos, São Bernardo) presented higher LRDM and lower SDM than the normal size varieties such as Mundo Novo, Bourbon Vermelho, Arábica, Amarelo de Botucatu, Glaucia, etc. The varieties Macrodiscus, Icatu-caturra, Bourbon Amarelo, Vila Lobos and C. congensis showed higher root development related to shoot. The Arábica coffee standard variety showed intermediary root and shoot development. Genotypes of high yield background were higher in SL and SDM, while the dwarf types had only lower SL than the normal ones, but higher RL and dry matters. Seedlings from genotypes of known higher field drought tolerance had lower SL and RL, but higher RDM. Significant phenotypic and genotypic correlation coefficients were obtained, such the genotypes for PL and PDM (r = 0.64; P = 0.01), SL and SDM (r = 0.40; P = 0.05), SDM and LRDM (r = 0.52; P = 0.05), RDM and LRI (r = 0.68; P = 0.01), LRI and SRDM (r = 0.85; P = 0.01) and LRI and LRDM (r = 0.84; P = 0.01). High genotypic correlations suggest that selection directed to one character will directly affect the other. Conversely, low or non-significant correlations suggest independence of association, an indication that it would be possible to select two characteristics to diverse directions. Selection could be done towards different goals to change root and shoot measures (length and dry matter) because they were genotypically independent. However, care should be taken in controlling the environmental effects, because of significant positive phenotypic correlations.

The correlation between the traits allows making an indirect selection, while the selection according to one trait results in the selection of another indicator. The purpose of the work is to estimate the variability of quantitative traits of Sudan grass and the correlations between them, to identify marker traits of high productivity and quality of green mass. There have been presented the study results of 115 collection samples of Sudan grass with various environmental and geographical origin of the Rostov region made in 2014-2018. There was a great variability (V=29.7-50.0%) in tillering, leaf square, green mass yield, stem diameter, plant height among the studied varieties.  The percentage of fiber and nitrogen-free extractive substances in the green mass of the studied Sudanese grass samples were characterized with high stability (V = 4.9-5.0%). The analysis has identified a strong correlation between green mass productivity and leaf length (r=0.59±0.01), leaf width (r=0.57±0.02), leaf square (r=0.54±0.03), plant height (r=0.48±0.06), length of ‘vegetation-ear formation’ period (r=0.48±0.004) and number of leaves (r=0.42±0.03). There has been identified a group of samples ‘Boldinsky’, ‘Fioros’, ‘К-176’, ‘К-205, ‘К-272’ with 35-55 t/ha green mass productivity and with 20.5-24.5% dry matter in green mass. The conducted analysis has shown that dry matter percentage greatly correlates with plant height (r=0.30±0.001), vegetation period (r=0.34±0.004) and number of leaves (r=0.26±0.006). The markers of high productivity and quality of green mass are length of a vegetation period and number of leaves (their increase results in the growth of green mass yields), dry matter percentage in green mass and protein decrease in it.

Abstract Boron (B) is a micronutrient tobacco needs in minute amounts, and Boron insufficient supply can causes significant tobacco yield loss, however, the appropriate concentration for flue-cured tobacco seedlings to growth remains unknown. In this sense, a hydroponic experiment was conduct to measure the agronomic traits, dry matter mass, chlorophyll content, photosynthetic performance, antioxidant enzymes, boron ion and nicotine content of flue-cured tobacco seedlings K326 under different boron concentrations of 0.000mmol/L (B1, CK), 0.125mmol/L (B2), 0.250mmol/L (B3), 0.750mmol/L (B4), 5.000mmol/L (B5), 10.000mmol/L (B6), 20.000mmol/L (B7), 40.000mmol/L (B8) after 30 days. B significantly influenced flue-tobacco seedlings growth on agronomic traits, photosynthetic performance, the activities of antioxidant enzymes, boron ion and nicotine content aspects. B linearly enhanced the accumulation of boron ion by 24.00%~96.44%, and decreased nicotine content by 21.60%~82.03% in tobacco seedlings. Solution B concentration at 0.750 and 5.000mmol/L markedly improved tobacco seedlings maximum leaf length by 4.83%~82.03% and leaf width by 0.77%~24.36%, root weight by 13.64%~56.82%, stem weight by 12.26%~52.36%, leaf weight by 9.68%~36.56%, dry matter mass by 10.65%~38.92%, the Pn parameter by 1.22%~80.28%, the Cond paramete by 33.40%~75.86%, while decreased the activities of SOD by 10.44%~91.67%, POD by 21.32%~65.62% and CAT by 50.05%~96.44%, and MDA by 16.23%~75.16%. The B concentration concluded in this study enhanced the agronomy traits, photosynthetic and biochemical characteristics of flue-cured tobacco seedlings, which lays a scientific theoretical foundation for rational application of B in tobacco production and improve the internal quality of flue-cured tobacco.

A longitudinal survey was conducted in 2013 to document the productivity of the Sesbania grandiflora feeding system for cattle fattening in central Lombok. Sesbania is integrated into the intensive rice-growing region by planting it along the rice bunds surrounding the rice fields. The hamlet of Nyerot in the subdistrict of Jonggat was chosen for the study as it had a long history of successful use of sesbania for fattening Bali bulls. Parameters measured included: area of rice paddy where sesbania could be planted; forage establishment, harvesting and feeding practices; cattle purchases and sales; and monthly liveweight gain. Farmers planted an average of 406 sesbania trees on bunds surrounding 0.6 ha of rice paddy. The median values for the main forages fed (dry matter offered) were harvested elephant grass (78% of diet), sesbania (12% of diet) and other feeds (mainly rice bran) (5% of diet). Sesbania was harvested by lopping the lower side branches of ~6 trees per bull per day and never completely defoliating single trees. The farmers fattened an average of 1.6 bulls at a time achieving a yearly mean liveweight gain of 0.41 kg/bull.day. New bulls were purchased with an average liveweight of 203 kg while the average sale weight was 260 kg. Purchase and sale prices were high at A$3.27 and A$3.29, respectively, while the average fattening period was 5 months. Bull liveweight gains were related to total amount of forage fed. No direct statistically significant link between liveweight gains and amount of sesbania fed was obtained due to the multiple factors that influenced forage and bull management. This survey has provided new insights into the practice of bull fattening in central Lombok. The survey has confirmed the high productivity of the feeding system and has highlighted the opportunity to scale out the use of system to other regions.

Characterization works of pitayas show that the potassium (K) is the nutrient most exported, thus, influences in the productivity and quality of this fruit. However, these researches do not report the nutrients export by pitaya's associating the fertilization carried out in the orchard, information that is relevant to make the nutrients reposition adequate at the time of fertilization. The research was carried out to evaluate the supply of K2O in the export of nutrients and productivity of the Hylocereus undatus and Hylocereus polyrhizus pitaya species. The analysis was carried out in the mature fruits harvested in two harvests. Potassium fertilization was performed at doses of 0; 50; 100 and 200 g of K2O per plant. Nutrient export per ton of fruit was calculated from the determination of the nutrient levels and the dry matter of the pitaya pulp. The export of nutrients by the pitaya of the species H. undatus and H. polyrhizus occurs in the following order: K>N>P>Ca>Mg> and Mn>Fe>Cu>Zn>B. These species of pitaya have similar nutritional requirements, enabling them to be receive same fertilization management. The amount of nutrients exported was higher in plants fertilized with potassium due to the higher productivity achieved. Orchards of pitaya that reach high productivity require a greater quantity of nutrients, due to the increase export by the fruits.
