The influence of some technological links on the productivity of three monoecious hemp unisexual female hybrids and the provenance variety, in A.R.D.S Secuieni cultivation conditions

Abstract

This paper aims to highlight the combined impact of the cutting method and the distance between plant rows on the monoecious hemp variety for seed – Zenit and on the unisexual female hybrids from three generations of crossbreeding, respectively retro-crossing. The researches were carried out in the Agricultural Research – Development Station Secuieni technological field, during 2017. The experience was of the trifactor type, the performed determinations were focusing on the biometric and productivity characteristics of the studied cultivars. The variety x cutting x distance combination generated remarkable yields for the HUF2 hybrid, sown at a distance of 50 cm between the plants rows, and to which two cuttings were applied (1816.7 kg/ha). Also, production results ensured at statistical level as very significant were obtained from interactions between HUF2 x T2 x 70 cm (1700 kg/ha), HUF3 x T2 x 50 cm (1643.3 kg/ha) and HUF2 x T1 x 70 cm (1626.7 kg/ha).
