Abstract:The study was conducted in three consecutive years from 2009 to 2011 in Zagora, Malësia e Madhe, in the North-western part of Albania, in a 10- years old vineyard, planted with a local wine grape cultivar named Kallmet. The plot was situated in an uniform hill with a sloping gradient from 5% to 6% and a planting density of 3330 plants ha-1 (2.5 m x 1.2 m). A randomized complete block design (RCBD) with 4 replications and 6 treaments with a plot size of 60 m2 for treatment in each replication containing 20 grapevine plants. The weather was dry in the summer with a typical Mediterranean distribution of precipitation from autumn to spring, and no irrigation was conducted throughout the whole experimental period. Six crop management practices were applied: conventional (no intervention and cultivation), chemical control (glyphosate and diuron applications) and organic (cover crops and straw mulching). Yield of grapes per plant (YGP), berry must content (BMC), must sugar content (MSC) and must acidity content (MAC) were recorded for a 3-year period. The data showed that different soil management practices influenced the grape production per plant, and must and sugar content under the irrigated growing conditions. Compared to common conventional farmer practices, organic soil management practices and chemical control of weeds provided higher yield due to reduced competition of grapevine plant for soil water reserves, thanks to reduced number of weeds and improved soil physical properties. Organic mulching and mixed leguminous cover crops seem to be the most sustainable practices in terms of yearly production and nature preservation.
