Protectants in the technology of growing cannabis seed

Abstract

In achieving high and stable yields of cannabis, an important link in the system of agrotechnical measures is seed etching. It increases the energy of germination and field germination, stimulates the growth and development of plants, is an indispensable and mandatory method of protecting seeds and seedlings in the field from major diseases and pests. Since there are no recommendations for the protection of cannabis from harmful organisms, it became necessary to carry out this work. The purpose of our work was to develop scientific foundations and identify effective options for processing seed material that promote plant growth stimulation, increase field germination, resistance to adverse environmental factors, which in turn will increase the productivity and yield of the crop. Scientific research was carried out at the FSBI FNC LC on the experimental field in the conditions of the Penza region in accordance with generally accepted current methods. It has been established that seed treatment with preparations of Lignohumate and Biocomplex BTU, TMTD, VSK and Albit, TPS activates plant growth in height, provides an increase in the technical length of the stem and inflorescence. When processing hemp seeds of the Vera variety with Lignohumate, Bunker, VSK and Albit, TPS protectants, the yield of stems increases by 9.5 – 22.0%, seeds by 10.0-23.1%, the hemp variety Nadezhda has the highest rates of stem yield (7.42-7.70 t/ha) and seeds (0.80-0.84 t/ha) obtained when using Bunker, VSK, Benorad, SP and Albit, TPS preparations in protection.
