The purpose of the current study was to identify the effect of the length of a vegetation period of the collection soybean samples on grain productivity and quality. The study was carried out in the southern part of the Rostov region in the fields of the FSBSI Agricultural Research Center “Donskoy” in 2018–2020. The climate is semi-arid with moderately hot summers. The soil is ordinary thick calcareous heavy loamy blackearth (chernozem). The forecrop was winter wheat. The objects of the study were collection soybean samples of the ARIGPR named after N.I. Vavilov. The study was carried out on 75 samples, including 52 middle early samples with 110-120 days of vegetation and 23 middle maturing samples (120-130 days of vegetation), differing in morphobiological and economically valuable traits. The analysis of a vegetation period, grain productivity and quality of the collection soybean samples has shown that in the southern part of the Rostov region the most variable trait was grain productivity (Cv = 22.5%). The less variable characteristics were protein percentage in grain (Cv = 3.8%), a vegetation period (Cv = 4.2%) and oil content in grain (Cv = 5.3%). There has been identified a positive effect of the length of a vegetation period of soybeans on grain productivity and oil content in grain for both groups of maturity, protein percentage in both groups of maturity having a negative dependence on a vegetation period. The study has shown that in the middle early group, the largest grain productivity was obtained with 117 and 118 days of vegetation, the highest protein percentage with 110 and 114 days of vegetation, and the largest oil content in grain with 118 and 120 days of vegetation. In the middle maturing group, the maximum productivity indicators were obtained for the samples with 126 and 130 days of vegetation, the maximum protein percentage with 122 days of vegetation and the maximum oil content in grain with 123 and 130 days of vegetation. The samples showing the maximum indicators will be included in further soybean breeding.

Variety Testing

In 2016-2018 in the competitive variety testing there was conducted the study of peas on the fields of research crop rotation of the laboratory of legumes breeding and seed-growing of the FSBSI “ARC “Donskoy” located in the zone of unstable humidity of the Rostov region (Zernograd district). The analysis of the obtained seeds was carried out in the laboratory of biochemical estimation of breeding material and grain quality of the FSBSI “ARC “Donskoy”. The objects of research were new pea lines of breeding of the FSBSI “ARC “Donskoy”, which differed in their morphological, biological and economically valuable traits and properties. During the years of research, the meteorological conditions of the vegetation period of peas were contrasting, which made it possible to objectively estimate the lines in the climatic conditions. In the competitive variety testing for the period of 2016-2018, the evaluation of new promising pea lines due to their productivity and protein percentage resulted in identification the leafless pea lines “G-1002” and “G-1003” which exceeded the standard variety “Aksaisky Usaty 5” in productivity (0.30 and 0.39 t/ha) and protein yield (0.08 and 0.10 t/ha, respectively). There is a high correlation between seed productivity and protein content (0.95). There is a low correlation between protein percentage in seeds and protein yield (0.35). There is no correlation between productivity and protein percentage in seeds (0.03). The analysis of correlations shows that pea breeding on productivity directly affects on protein yield, i. e. the larger seed productivity, the larger protein percentage. The most productive pea lines are going to be used in further breeding work.

Caraway has very low competitive ability against most of weed species. Therefore, it is important to choose a suitable herbicide control, especially at biennial caraway. The experiments with the herbicides applied in caraway were found in pure growth, with variety Kepron (with standard length of ve­ge­ta­ti­ve period). The aim of the trials was to find out the differences at achenes yiled and essential oil content after the treatment by the various herbicides, applied preemergently. Also, the selective ac­ti­vi­ty of individual herbicides was tested, including the different doses. The herbicides used in the ex­pe­ri­ments had enough level of selektivity on the plants of caraway. They had a positive effect on the yiled comparing to non-treated control variant in all observed years. There was no statistically significant difference in essential oil kontent between the treated variants and non-treated control. On the basis of these results, the most suitable herbicide was chosen for the „minor“ registration for caraway.

Variety Testing

The studies were carried out in 2016–2018 in the competitive variety testing of peas on the crop rotation fields belonging to the laboratory of legume breeding and seed-growing of the FSBSI “Agricultural Research Center “Donskoy”, located in the part of the Rostov region with unstable humidity (Zernograd). During the years of research, the meteorological conditions of the pea vegetation were contrast that made it possible to objectively estimate the pea lines in the given weather and climate conditions. In the com­petitive variety testing, the 18 lines were studied according to economically valuable traits (seed productivity, productivity elements, adaptability to machine harvesting). As a result of the study, the 6 pea lines were identified: 2 lines of the mustache morphotype “G-1002”, “G-1003”; 4 leafy lines “G-1010”, “G-1011”, “G-1013” and “G-1015”. In the group of the mustache morphotype, 2 lines “G-1002” (on 0.30 t/ha), “G-1003” (on 0.39 t/ha) exceeded the grain productivity of the standard variety for 3 years of study on aver­age. The productivity increase was from 12.4 to 16.1%. In the group of variety samples of the leafy morphotype, the line “G-1010” (on 0.31 t/ha) significantly exceeded grain productivity of the standard variety. All the selected lines were tolerant to their seed-shedding. The line “G-1010” (48.8 pc per plant) showed the highest seed yield per plant. The lines “G-1003” (222.1 g), “G-1011” (209.5 g) and “G-1013” (207.8 g) had the largest fineness of grain. The line “G-1010” (8.85 g/plant) demonstrated the highest productivity per plant. However, having a low coefficient of resistance to lodging (0.35), this line has the greatest loss of seeds during harvesting. The iden­tified lines will be used in further breeding work according to a number of their economically valuable traits.

An improvement in the quality of maize grain by increasing the level of components responsible for its biological value is possibleby using genetic means. However, a change in the genotype, together with improving the nutrient properties of the grain, also has someadverse consequences connected with a fall in yield and in resistance to diseases.Field experiments were conducted during three years (2003, 2004and 2005) to evaluate environmental effects on grain yield andquality responses of maize hybrids. Twenty one hybrids of various maturity groups (FAO 150-400) were planted to achieve an optimum(60-70 000 plants per hectare) plant populations and grown under the medium-N (80 kg N ha-1) fertilization. Environmental conditionssignificantly affected maize hybrid responses for grain yield, starch, oil and protein contents, and consequently, starch, oil and proteinyields per hectare. Hybrids of flint type, which have a short vegetation period, had high protein and oil content but the yield averageswere low due to the slower rate of starch incorporation. Hybrids of the dent type have a longer growing season and more intensecarbohydrate accumulation, but low protein and oil contents. In wet years there was a higher rate of starch accumulation, while dryyears are favorable for protein and oil accumulation. Positive correlation existed between starch content and grain yield and 1000-weight as well as between oil content and volumetric weight among tested hybrids. Negatively correlation existed between grain oil andstarch content as well as between oil content and grain yield and 1000-weight. Thus, end-users that require high quality maize may needto provide incentives to growers to off set the negative correlation of grain yield with oil and protein content.

The article presents the study results of seed inoculation by specific strains Mesorhizobiumciceri on number and weight of chickpea root nodules, productivity and nutrition value of chickpea cultivated in the southern nature-climatic part of the Rostov region.  The study was conducted on the fields of FSBSI “Agricultural Research Center “Donskoy” (in the laboratory of cultivation technology of row crops) located in the southern part of the Rostov region in 2015–2016. The soil of the plot was heavy loamy carbonate blackearth (chernozem) with 7.0 рН, 3.2% of humus, 18–25 of P2O5 mg/kg of soil and 350–400 of K2O mg/kg of soil. The object of the study was a chickpea variety ‘Volgogradsky 10’, approved to use in the Rostov region. The strains of nodule bacteria (Rhyzotorfin) were developed and presented by the FSBSI All-Russian Research Institute of Agricultural Microbiology (the laboratory of ecology of symbiotic and associative rhizobacteria). Agroclimatic conditions of chickpea vegetation period ranged throughout the years of study that allowed estimating chickpea productivity without fear or favor. The use of Rhyzotorfin strains resulted in increasing preservation of plants for harvesting, improving seed productivity (seed-weight per plant, 1000-kernel weight) and increasing grain productivity (with the increase on 0.24–0.51 t/ha compared with the control). Large yields of fodder units and raw protein per unit area testified the improvement of nutrition value of chickpea kernels, and the increase of these traits to the control was 0.33–0.68 t/ha and 26.5-93.1 kg/ha respectively.

Rice is a valuable agricultural crop that is used as food for more than half of the world's population. The development of highly productive varieties and hybrids with high product quality assumes the utilization of new initial material from different countries in the breeding process. The purpose of the current research was to conduct an ecological testing of the rice varieties from Uganda in the Proletarsky district of the Rostov region in Russia and use them in the breeding process. There were studied the Ugandan rice samples ‘Nerica 1’, ‘Nerica 4’, ‘Komboka’, ‘Wita 9’, ‘Namche 1’, ‘Namche 2’, ‘Namche 3’, ‘Namche 4’, ‘Namche 5’, ‘Namche 6’ (NaCRRI) in comparison with the Russian variety ‘Komandor’ (FSBSI “ARC “Donskoy”). The study of the Ugandan rice varieties according to a number of economically valuable traits and biological properties showed that the vegetation period from soil flooding to rice maturing took 100–113 days, the standard variety ‘Komandor’ needed 83 days. The varieties ‘Komboka’ and ‘Wita 9’ did not bear blossom. All samples had a short habit, with 63-95 cm of plant height. The long drooping panicles of 18.5–22.3 cm carried from 122 to 213 seeds. The caryopses were elongated, the length of the caryopses varied from 9.0 to 9.5 mm, and the width ranged from 2.7 to 3.1 mm. 1000 seed weight varied from 26 to 34 g, number of seeds per panicle ranged from 122 to 213 pieces. Genetic analysis of the second generation hybrids ‘Kontakt × Nerica 1’ and ‘Boyarin × Nerica 4’ showed different types of traits’ inheritance, from negative dominance (vegetation period) through the absence of dominance (caryopses size) to overdominance (plant height, seed weight per panicle and number of seeds per panicle).

Changing climatic conditions and the loss of immunity to diseases and pests of the developed varieties make breeding work to create new genotypes of great necessity. The new middle-early maize hybrid ‘Zernogradsky 299 MB’ of universal direction of economic use (for grain and green fodder) has been developed in the “Agricultural Research Center “Donskoy”. The hybrid is three-linear; it belongs to the varieties with crown yellow grain Zea mays L. indentata. It possesses high values of the main economically valuable traits. The average grain productivity through 3 years of competitive variety testing (2014–2016) was 5.36 t/ha, the variety yield exceeded the standard variety ‘Zernogradsky 291 AMB’ on 0.41 t/ha (8.3%). The average productivity of green mass is 27.6 t / ha, which is higher than that of the standard variety on 2.4 t/ha (9.5%). The new hybrid is resistant to lodging (2.1% of lodged plants), drought-resistant, resistant to smut on a natural background (0.4% of affected plants), has a high starch percentage (71.9%). In 2018, according to the results of the State Variety Testing, a new hybrid was introduced into the State List and approved for use in the Central Blackearth and NizheVolzhsky regions to cultivate it for grain and green fodder. It has a high potential for grain productivity. The maximum yield (11.23 t/ha) was obtained in the Central Blackearth region on the Oboyansk plot of the Kursk region, which is higher than the standard variety ‘Voronezhsky 279 CB’ on 2.03 t/ha (22.1%) with lower grain harvesting moisture (on 1,6%) than the standard variety.

The current study was carried out on ordinary blackearth (chernozem) in the southern part of the Rostov region in the FSBSI “ARC “Donskoy” (2017–2020 agricultural years). The purpose of the work was to identify the effect of autumn and spring sowing periods on grain productivity and quality of the facultative barley variety ‘Marusya’ according to various forecrops. There has been considered the dynamics of the productivity of the variety ‘Marusya’ depending on the sowing time when sown after maize for grain and sunflower. There has been established high adaptability of the variety ‘Marusya’ after nonfallow forecrops. It has formed a high productivity when sown in autumn at various times. There has been found out a positive reaction of the variety to sowing on September 10, 20 and 30, where the maximum productivity when sown after maize for grain was 6.76–6.91 t/ha. When sowing at later time, there was a slight decrease in productivity. When sown in spring, the highest protein percentage in grain was 11.0 and 11.6%. However, due to the highest productivity, the maximum protein yield was when sowing in autumn, up to 0.71 t/ha. The calculation of the economic efficiency of grain production showed that the highest profitability (214.1 and 214.4%) was obtained when the variety ‘Marusya’ was sown on September 10 and 20 after maize for grain. On average, over the years of study, the maximum conditional net income according to the forecrop, depending on the sowing time, was from 59658 to 84261 rubles/ha when sown in winter and from 48881 to 59170 rubles/ha in spring. The minimum profitability 62.1–75.2% was identified when sown in spring in 10 days after the soil was physically mature.
