The influence of cultivation techniques on the productivity of drug-free cannabis

Abstract

The influence of seeding methods, seeding rates against the background of pre-sowing and foliar treatments of seeds and plants on the yield and quality of hemp products at the experimental site of the Penza branch of the Federal State Budgetary Scientific Research Center LC has been studied. The research was carried out on leached chernozems in two three-factor experiments in 2020-2021. As a result of the research, the influence of the studied factors on the yield of hemp products was established, so with a wide-row sowing method, high yields of stems (10.26 t/ha), the yield of total (2.95 t/ ha) and long fiber (2.03 t/ha) were obtained with a combination of pre-sowing and foliar treatments with humic preparation and seeding rates of 1.2 million pcs./ ha, the optimal seeding rate for the ordinary method of sowing is 3 million pcs. / ha, which provided an equalized stem with good quality and high yield of total (2.82 t/ ha) and long (2.21 t/ha) fiber, while treatment with a humic preparation before sowing gives an additional 0.8-1.2%, treatment of vegetative plants increases this parameter by 0.6-1.2%.
