The weed composition and the dominance of individual species occurring in an orchard were assessed at the Research Station of the Wrocław University of Environmental and Life Sciences, Poland, during the first 10 years after orchard establishment. ‘Ligol’ apple trees were planted in the spring of 2004 (3.5 × 1.2 m). Foliar herbicides were applied in 1 m wide tree rows twice or three times per each...
In a study conducted at the Research Station of the Wrocław University of Environmental and Life Sciences, weed occurrence in living mulches maintained in apple tree rows of ‘Pinova’ cv. was assessed during the first seven years after sowing. The trees were planted in spring 2004 (3.5 × 1.2 m). In the same year, living mulches: colonial bent grass, white clover and French marigold, were sown into...
Since many years the usefulness of different rootstocks has been estimated because of the cropping level, the growth, the physiological incompatibility between scion and rootstock and the mortality of the apricot trees. The Myrobalan, apricot seedlings, ‘Wangenheim Prune’ plum tree cv. and other rootstocks were evaluated in the earlier investigations. The study on the Lower Silesia area was conducted...
The preliminary studies were conducted in the years 2006-2008 at the Fruit Experimental Station of Wrocław University of Environmental and Life Sciences. One year old trees of Harcot, Hargrand and Bergeron cultivars grafted on Pumiselect® vegetative rootstock were planted in spring 2006, at a spacing of 4.0 x 3.2 m (780 trees∙ha-1). The experiment was established in a randomized block design in 4...
Doświadczenia założono na dwuletnich drzewach gruszy odmian Harrow Sweet i Pstrągówka uszlachetnionych na pigwie S1 oraz na czteroletnich drzewach jabłoni odmiany Pinova zaokulizowanych na P 60. Drzewa prowadzono w koronie wrzecionowej, w rozstawie 3,5 x 1,2 m (2381 drzew∙ha-1). Badano wpływ sposobu prowadzenia gleby w rzędach drzew. Jako kontrolę zastosowano ugór herbicydowy. W rzędy drzew odmiany...
