Research on the effect of applying different doses of biostimulators on the monoecious hemp agroproductive capacity

Abstract

The paper aims to highlight the singular and combined effects of the cuttings application and three types of biostimulators, in different doses, on the seed production of the Secuieni - Jubileu monoecious hemp variety. The research was carried out in the technological field of SCDA Secuieni, during the year 2020. The results revealed the highest seed yields (2022 kg·ha-1), supported at a very significant statistical level, in the case of the application of two cuttings. At the same time, the biggest influence was determined by the use of the biostimulatorAsfac BCO - 4, at a dose of 1.5 l·ha-1, the registered yield increase (790 kg·ha-1) being very significant, compared to the control variant (unfertilized). The combined influence of the studied factors determined the highest yield increase (1420 kg·ha-1) in the case of the variant on which two cuttings and Asfac BCO-4 were applied, at a dose of 1.5 l·ha-1.
