Dependence of the yield of stems of varieties of technical hemp on the influence of seed sowing rates under the narrow-row method of sowing

Goal. To investigate the effectiveness of seed sowing rates in terms effect on yield technical hemp stem production process culture cultivation technology. Methods. Field, laboratory. Factors influence which were involved field research: factor A — rates, options 1.2; 1.8; 2.4; 3.0; 3.6 million seeds/ha; B YuSO-31, Hliana, Hlesiya varieties Institute Bask Cultures NAAS. The width between rows experimental crops was 15 cm. placement plots systematized storeys. number repetitions 4 times. stems determined by direct harvesting sub-divisions. obtained data, statistical-mathematical analysis used, as well dispersion and correlation-regression at level reliable probability P0.95. Results. a technological nature established. Conclusions. It that impact for their increase within 1,2; 3.0 seeds/ha YuCO-31, less effective. With an rate from 1.2 to 1.8 2.4 units/ha, significant all observed with gradual decrease specified factor. In following comparison indicators seeds/ha, no differences results found. dependence result sign influencing is characterized strong correlation.
