THE PRODUCTIVITY OF SOME MONOECIOUS HEMP VARIETIES (FOR FIBER AND MIXTE) UNDER THE CENTER OF MOLDAVIA ECOPEDOCLIMATIC CONDITIONS

Abstract

The present paper presents the results obtained regarding the evolution of stem and fiber production in monoecious hemp, under the pedoclimatic conditions of the Center of Moldova, between 2012 and 2016. The biological material used was represented by four monoecious hemp varieties created at S.C.D.A. Secuieni, respectively, Denise, Diana, Dacia – Secuieni and Ratza. The stems yields achieved, have varied widely, ranging from 7860 kg/ha at Denise variety, in 2016 (a very warm agricultural year from the thermal point of view and rainy from the pluviometric point of view), and 15167 kg/ha, at Dacia - Secuieni in 2014 (a normal agricultural year both from the thermal and pluviometric point of view). On average, during the five years studied, the highest production of fiber was obtained in the Dacia-Secuieni variety in 2014, of 5005 kg/ha, and the lowest of 2279 kg/ha at Denise variety in 2016.
