We compared the separate harvesting with the use of a hemp harvester LCD-1,9 followed by threshing with a threshing machine MLK-4,5 and harvesting with combine harvesters of various modifications. Practical studies on the use of direct harvesting on seed hemp have shown positive results in solving the problem of harvesting seed crops without manual labor. The introduction of combine harvesters in the process of harvesting hemp for seeds contributed to a gradual increase in the acreage in Russia, so, in 2010, the area occupied by this crop was at the level of 1.1 thousand hectares, by 2022 it reached 14.3 thousand hectares, and in the future it is planned to expand the acreage. The Penza Research Institute also has a positive trend in the expansion of acreage, so, in 2014, the acreage occupied 9 hectares, in 2022, the acreage increased to 102 hectares. The volume of collection of original seeds has increased from 2 to 60 tons. When comparing seeds obtained after different harvesting methods, a difference was found in the amount of damage, the amount of laboratory germination, the development of pathogenic microflora, and therefore it is necessary to further improve the technology of harvesting cannabis.","PeriodicalId":485427,"journal":{"name":"Аграрный научный журнал","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136036505","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}

They cultivated a variety of oilseed flax Heavenly. The predecessor is winter wheat. The following types of mineral fertilizers were used in the experiment: ammonium nitrate (34.4 % N), ammophos (12-52), potassium chloride (K2O65). The use of mineral fertilizers was carried out in the autumn period for plowing the soil, in the spring for continuous cultivation and for sowing oil flax. Bacterial preparations are intended for the treatment of flax seeds in the pre-sowing period: Mizorin, Flavobacterin, Extrasol. Average for 2020-2022 the maximum increase from the use of agro-chemicals was achieved in the variant with the introduction of nitrogen-phosphorus fertilizers under continuous cultivation at a dose of N60P60. The increase in the yield of flax oilseeds was 0.74 t/ha, or 51.7 % compared to the control. A high effect was achieved from the treatment of seed material with the biological preparation Extrasol (200 ml per sowing rate of seeds). The increase in the yield of oilseeds reached 0.19 t/ha to the variant without the use of fertilizers. With the combined use of fertilizers and bacterial preparations, the best effect on the yield of flax was achieved from the treatment of seeds in the pre-sowing period with bacterial preparations Flavobacterin and Extrasol. The increase in comparison with the control variant was 0.51 t/ha, or 31.5 %. On average, over 2 years, the largest oil yield in the crop was obtained in the variant using N30P30.

The average daily milk yield in the experimental group of first-calf heifers was 9.3 % higher than in the experimental group. This made it possible to milk in the experimental group, on average, one head more milk in its natural form than in the control group by 250.5 liters. Additional milk yield in the experimental group, in terms of the basic milk fat content of 3.4 %, amounted to 547.5 liters, and the profit from the sale of this milk per 1 head of the experimental group was more by 16.6 thousand rubles, compared with the control. The use of chlorella suspension in feeding cows of the 2-nd and 3-rd lactations shows that 534.2 liters of milk can be additionally obtained from one cow in 99 days, based on a basic fat content of 3.4 %.

In experimental surveys, both zoned varieties of spring (Krasnokutka 13 - control, Don elegy) and winter (Aksinite and Agate of the Don) durum wheat were studied. The experimental part was carried out in 2018...2021 on the territory of the farm \"Eliseev A.N.\", which is located in the chernozem zone of the southern Mikhailovsky district of the Volgograd region. The norms of mineral nutrition for yields of 2.00, 4.00 and 6.00 t/ha were calculated. The long-term experience has shown that biofertilizers (Benefit +, Gumi 20) can compete with mineral nutrition to obtain a given yield of durum wheat. The use of biofertilizer Gumi 20 contributed to a yield of 3.11 t / ha in the Don Elegia variety, and in winter durum wheat Axinite up to 3.73 t / ha. The highest yield level has Axinite), which amounted to 5.96 t/ha (with a planned yield of 6.00 t/ha).

We established that postpartum endometritis in first-calf heifers is widespread in biogeochemical provinces that contain an excess of nickel and iron. This pathology demonstrates distinct violations of organism’s functional state, accompanied by changes of blood values, a decrease in nonspecific defenses and an increase in peroxidation processes. The on-farm treatment routine makes a certain therapeutic effect, but does not fully ensure the restoration of the body systems, especially the regulation of mineral metabolism. It has been shown that the additional inclusion of Phosprenyl, Gabivit-Sе and Vitartil, which stimulate organism’s defenses, into the on-farm treatment routine contributes to faster restoration of metabolic processes and leads to recovery of animals. Normalization of indicators of nonspecific defenses was detected both on the 7th and 14th days of treatment. An integrated treatment approach due to introducing of the studied medications into the traditional routine helps to reduce the time of treatment of endometritis in first-calf heifers (by 3-4 days), and their milk production increases. The daily milk yield in the experimental group of cows was 18,6±0,29 kg, in the control group – 15,3±0,33. Therefore, the Phosprenyl, Gabivit-Sе and Vitartil should be included in the basic routine of on-farm treatment of endometritis.","PeriodicalId":485427,"journal":{"name":"Аграрный научный журнал","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136036506","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}

Experimental studies have shown that after the use of regostenol in cows with a persistent corpus luteum, 75.0% of animals became pregnant with an insemination index of 1.8.
