The studies were carried out in 2019–2020 on the fields of the FSBSI Federal Research Center for Bast Fiber Crops of the Pskov. Experimental options included three factors: levels of mineral fertilizers - control (without fertilizer), N60P60K60, N90P90K90, N120P120K120; seeding rates - 4, 5 and 6 million germinating seeds/ha; sowing dates - I and II decade of May. Studies have shown that the largest weight of 1000 grains - 37.5 and 37.7 g - was obtained when sowing emmer in the second decade of May with a seeding rate of 5 and 6 million units/ha against the background of applying mineral fertilizers at a dose of N90P90K90. On average, over the years of research, according to the variants of the experiment, from 16.5 to 25.8 q/ha of spelled grain was obtained. It has been established that the most effective factor is the use of mineral fertilizers, which, in the studied doses, provided an additional 2.4 to 5.5 q/ha of grain according to the experimental options. The shift in the sowing date of spelt to the second decade of May made it possible to have a significant increase in yield from 2.2 to 4.0 q/ha of grain. Seeding rates turned out to be a less effective factor, an increase in which from 4 to 6 million units/ha contributed to an increase in grain productivity by 1.5–4.1 q/ha. The highest yield of spelled at the level of 25.1–25.8 q/ha was obtained when the crop was sown in the second decade of May with seeding rates of 5 and 6 million units per hectare against the background of mineral fertilizers N90P90K90.","PeriodicalId":219145,"journal":{"name":"The Agrarian Scientific Journal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126301675","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 operating principle of this method of chippings removal is based on using the kinetic energy of rotating blades, from which the particles, receiving a certain amount of it, are directed in a stream of mixture with air through the chippings pipeline into the transport container. The specified method has inherent disadvantages - not always a stable process of removal of the resulting chips, which does not allow to achieve effective operation of chippers with this design. It is established that the design features of the chipper chipper pipeline have a significant influence on the removal of these particles from the chipper shell, especially in view of the predominance of the fine fraction obtained as a result of chopping twigs, branches and tops. The very long length of the chipper pipeline, the specific geometric shape in its various sections, as well as the considerable height of the chip elevation, from 2 to 4 meters, from the disc knives to the outlet window, have a restraining effect on the movement of the chips and on the performance of the entire mechanism.","PeriodicalId":219145,"journal":{"name":"The Agrarian Scientific Journal","volume":"66 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117179264","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 disease was monitored on fields of V.S. Pustovoit All-Russian Research Institute of Oil Crops, Krasnodar. Analysis of climatic factors in years of the research resulted that heavy rainfalls (119.2?134.6 mm) exceeding multi-year averages (60.0 mm) by two times and the optimal average daily temperature 23.0?26.4 ?С in July are favorable for stem infection by Plenodomus lindquistii in the second half of the summer, in a phase of sunflower flowering – maturing. In 2018, the moisture deficit in June (11.0 mm) and August (6.8 mm) was a factor suppressing the viability of an infectious matter of a fungus that led to a low frequency of Phoma black stem on the sunflower lines (in average 20.3%). In 2019 and 2020, prevalence (P) and development (R) of Phoma black stem in average on sunflower lines were equal 23.3?29.9% and 21.4?28.1%, respectively. A line L 107 demonstrated a stable resistance to Plenodomus lindquistii infection during three years: amount of infected plants was within 5.7?8.3%, development was 3.8?8.3% at the infection level of 1–2 points. A susceptible line L 116 was selected (P: 47.5?62.8%, and R: 38.0?40.0%).
