| Abstract | ||
| This study was conducted for three successive seasons (2010, 2011 and 2012) on adult King Ruby grapevines at Baramon Horticulture Station, Dakahlia Governorate. The vines were ten-year-old, grown in a clay loamy soil and irrigated by flood irrigation system. Vines were planted at spaced 2 X 2.5 meters apart and trained as bilateral cordon system. Ammonium sulphate 20.6% was applied as source of mineral fertilization. Cover crops were planted among rows either Clover or Peas plants. Seven treatments of N units were applied as follows: 60 N-unit (Control), 60 N-unit + cover crop of Clover plants, 60 N-unit + cover crop of Peas plants, 45 N-unit + cover crop of Clover plants, 45 N-unit + cover crop of Peas plants, 30 N-unit + cover crop of Clover plants and 30 N-unit + cover crop of Peas plants. The results showed that application of 60 N-unit with cover legumes crops either Clover or Peas plants were the best combined system, where they gave achieving the significant yield and its components. Also, they had significant of bunches, physical and chemical characteristics of berries, as well as nitrate and nitrite content of berries was decreased and best vegetative growth parameters and leaf mineral content of nitrogen, phosphorus and potassium of King Ruby grapevines were significant increased. | ||
