Sowing at the previously recommended scientifically based optimal time no longer guarantees stable yields of maize. Based on this, the purpose of the study was to determine the effect of the sowing time of new promising maize hybrids of our own breeding on productivity and yield structure elements in the steppe part of Kabardino-Balkaria. The study was carried out in field trials on the field of the research and production site of the Institute of Agriculture of the KBRC of the Russian Academy of Sciences in 2019–2021. In general, during the years of study, weather conditions were typical for the steppe area of the KBR. As a result, there was determined that the optimal sowing time for maize hybrids was the second decade of April. When sowing at this time, there was identified productivity improvement and an increase in the values of yield elements. On the contrary, sowing in the third decade has shown a decrease in the values of these indicators in all studied samples. During the second sowing period, there was the greatest productivity decrease among the late-maturing hybrids ‘Karat SV’, ‘Terek’ and the hybrid population ‘Kabardinskaya 3812’ by 1.4; 1.5 and 1.8 t/ha, respectively. The middle-early hybrid ‘Maisky 260 MV’ has shown a smaller decrease by 0.7 t/ha. During the first sowing period, number of ears per 100 plants increased by 4–11 pieces. The ears were better grained with 5–60 pieces of the excess over the second period. The weight of one cob during the first sowing period ranged 105–120 g on average, which was 9–22 g more than the same indicator during the second sowing period.","PeriodicalId":508743,"journal":{"name":"Grain Economy of Russia","volume":" 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141831354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the Rostov region, on the territory of the Don Experimental Station (the Azov region), severe damage by the sunflower rust pathogen was established in 2020. In this regard, there was a need to study the race of the fungus on sunflower crops in the Rostov region. The purpose of the study was to identify rust pathogen isolates collected from sunflower crops in accordance with the accepted international triplet nomenclature in different areas of the Rostov region in the period 2021–2023. As testers, there was used a set of differentiating lines of sunflower resistance to the pathogen, containing SM 90, SM 29, P-386, HA-R1, HA-R2, HA-R3, HA-R4, HA-R5 and the line ‘ED 47’, susceptible to all biotypes of the fungus. The total sample consisted of 237 parasite urediniospore isolates collected from infected leaves of sunflower plants. There were differentiated 34 biotypes of P. helianthi. The most virulent pathotype 777 was identified among isolates from the Tatsinsky, Morozovsky and Konstantinovsky districts of the region in 2023. The race with code number 700 was identified in almost all represented areas of the region and accounted for 52.7% of the studied sample of sunflower rust pathogen isolates. In the current work the racial composition of the pathogen in the Rostov region was studied for the first time. The study results have indicated the need to continue monitoring new biotypes of P. helianthi, as well as expand and accelerate work on the development of sunflower hybrids resistant to the predominant race with code 700 in the sample.","PeriodicalId":508743,"journal":{"name":"Grain Economy of Russia","volume":" 21","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141831743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was carried out in a stationary field trial of the FSBSI “Kursk FARC” on typical heavy loamy blackearth (chernozem) in 2015–2023. Agricultural crops were grown in three crop rotations: 1 – grainrow fallow (black fallow, winter wheat, sugar beets, maize for silage, barley); 2 – grain-row green manure fallow (green manure fallow, winter wheat, sugar beets, maize for silage, barley); 3 – crop rotation (horse-bean for grain, winter wheat, sugar beets, white lupine for grain, barley). During the trial there have been compared two contrasting levels of mineral fertilizer application N30Р30К30 and N52Р52К52 per hectare of crop rotation area. The non-marketable portion of the harvest of all crops was used as fertilizer. Agricultural technology was generally conventional for the area. There has been established that, under all weather conditions, the highest yield of winter wheat at a low background of fertilization (N30Р30К300 per hectare of crop rotation area) is produced in green manure fallow, and at a high background of fertilization (N52Р52К52 per hectare of crop rotation area) in black fallow. There was found that the most favorable conditions for cultivating barley were created when cultivating with white lupine for grain. Fertilization increase led to productivity increase of the grain crops, but, at the same time, to a production profitability decrease. There has been determined that productivity of crop rotations with fallow forecrops is 14 % higher compared to crop rotations with a legume forecrop (horse-bean for grain). According to calculations, on average over the years of study, the most profitable was the winter wheat cultivation in black fallow, and spring barley cultivation in white lupine for grain. At the same time, the indicator of production profitability level decreased with an increase in the rate of mineral fertilizing, which results in production costs’ increase.","PeriodicalId":508743,"journal":{"name":"Grain Economy of Russia","volume":" 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141832603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, breeding for lodging resistance is one of the most important criteria in pea breeding programs. The purpose of the current study was to search for anatomical indicators that could serve as a criterion when selecting pea samples for lodging resistance. The field trials were carried out in the fields of the laboratory for legumes breeding and seed production, the laboratory study was conducted in the laboratory for cell breeding of the FSBSI “ARC “Donskoy” in 2022–2023. The estimation of lodging resistance was carried out on 22 pea samples of the regional and foreign breeding. The studied samples differed in plant height, morpho-anatomical features of a stem structure, and lodging resistance. Based on the results of estimating an anatomical structure of a pea stem, there were identified such samples with a complex of traits (number of bundles, ratio of a number of bundles to stem tissues) as ‘Lu-153-06’, ‘G-1234’, ‘G-1193’, ‘G-1288’, ‘AKM’, ‘G-1313’, ‘Flagman 10’, ‘G-1313’. The analysis of correlations between anatomical indicators and field resistance to lodging has shown a high positive correlation with a stem height (r = 0.78±0.14), a mean negative correlation with a plant height (r = -0.66±0.17), and a mean positive correlation with a number of vascular bundles (r = 0.69±0.16). The experimental results allow concluding that the estimation of lodging resistance based on an anatomical structure of a pea stem is effective and can serve as a tester for lodging resistance.","PeriodicalId":508743,"journal":{"name":"Grain Economy of Russia","volume":" 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141833228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
