Productivity of vineyards with differently trained vines under semicovered vine growing

Abstract

the article summarizes data from the study conducted in 2005-2012 on three
shapes of vine plants under semi-covered vine growing. the following shapes were
studied on the cultivar ‘Pervenets Magaracha’: bilateral oblique cordon, unilateral
horizontal cordon with a reserve arm, bilateral horizontal cordon with a reserve
arm. the vineyards’ profile: planted in 1986, own-rooted, non-irrigated, with the
growing space of 3 x 1.5 m. on average, the vine trained as bilateral horizontal
cordon with reserve arm stood out over the years of plantation productivity studies.
the harvest of the vineyards amounted to 14.2 t/ha due to higher load of plants
with fertile shoots and their fruitfulness.
