The behavior of hemp unisexual female hybrids comparative with the monoic parental form, under the influence of applied cuts

Abstract

The paper aims to highlight the agroproductivity of unisexual female hybrids from three generations (HUF1, HUF2 and HUF3) compared with Zenit monoic parental form. The researches were carried out between 2015 – 2016, in A.R.D.S Secuieni experimental field. The experience was of bifactorial type, following the biometric characters and seed yields of the studied genotypes, under the influence of applied cuts during the vegetation period. The obtained results showed that, on average over the two experimental years, the seed yields were statistically ensured at a very significant level for T2 (two cuts – 1319.7 kg/ha), respectively distinctly significant for T1 (one cut – 1238.7 kg/ha) compared with the uncut variant (control). The interaction between cutting x genotype factors has generated, on average, very significant yield differences for the combinations of HUF2 and the three cuttings (NT x HUF2 – 175.3 kg/ha, T1 x HUF2 – 361.6 kg/ha, T2 x HUF2 – 480.6 kg/ha). Very significant productions were also provided by the combinations between HUF1 and HUF3 hybrids and the T1 and T2 cuttings.
