The influence of the method of harvesting seeded hemp on the yield and quality of seeds in the conditions of the Middle Volga region

Abstract

In the conditions of the Penza region in 2014-2022, field studies of various methods of harvesting seeded hemp were conducted. 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.
