Study on monoic hemp lines, obtained at the Agricultural Research Station of Secuieni, Neamţ county, concerning the stem, fibre and seed production

Abstract

During 2003-2006, at the Agricultural Research Station of Secuieni, Neamţ County, 20 lines of monoic hemp were tested for stem, fibre and seed production. As control, we have used the monoic varieties Diana (for stems and fibre) and Zenit (for seed). After 4 years of experiences carried out on stem and fibre production, we noticed the following lines: SCM-15 (9.63 t/ha stems and 3.08 t/ha fibre), SCM-19 (10.4 t/ha stems and 3.08 t/ha fibre) and SCM-20 (10.03 t/ha stems and 3.01 t/ha fibre). In 2005, a year favourable to stem and fibre production, the SCM-19 line has obtained the highest yields of 12.3 t/ha stems and 3.69 t/ha fibre. As concerns the seed yield, SCM-3 (74.25 kg/ha), SCM-4 (1073.50 kg/ha) and SCM-7 lines (947.25 kg/ha) proved to be superior to the control. Under the favourable conditions to seed production (year 2004), the SCM-4 line has obtained the highest yield of 1530 kg/ha. The SCM-19 line may represent the basis of a future mixed variety of monoic hemp, exceeding the control varieties used for stems, fibre and seed.
