This investigation was undertaken for three seasons 2003. 2004 and 2005 on seven years old Thompson seedless grapevines grown in a clay loam soil at EL— Baramon Research station. Mansoura. Dakahlia Govemorate. Treatments included in the experiment were : management of row middtes (cultivated vs. perennial legume cover crops) and nitrogen fertilization (compost vs. mineral fertilizer). Leaf area. bud fin‘lity. vine nutrititional status. yield. fruit composition weight of prunings were monitored each season (2003 — 2005) .Conventional cultural practices (cultivation and mineral fertilizer) produced the highest yield, cluster weight .frult weight 8. diameter. TSS . TSSIacid ratio in the first season .yet. the significant difference disappeared in the third season owing to that the legume cover crop had become fully established Cover crop with mineral fertilizer treatment increased leaf area . weight of prunings and mineral content of leaf petioles in the first season whereas , cover crop + compost treatment gave the highest values in the third season . The highest nitrate and nitrite residues in the berries were observed in mineral fertilization .whereas the lowest values were gained from compost with peas or clover cover crop treatments.
