THIS INVESTIGATION was conducted during the successive seasons (2014& 2015) in a private vineyard located at Menshiat Abdel Nabi village, Aga, Dakahlia Governorate, Egypt. The chosen vines were seven years old, planted in a clay soil, spaced at2×2.5  meters apart and irrigated by flood system. Flame seedless was spur pruned by leaving 7 spurs with two eyes on each cardon,  the total load was 56 buds under pergolla trellis system, while Thompson seedless was cane pruned by leaving 6 cans with 12 buds/cane with 6 renewal spurs with two  buds for each, the total bud load was 84 buds under double T trellis system. All intercropped peas and clover received cultural managements as recommended by the Egyptian Ministry of Agriculture. The obtained results reveal that intercropping of Thompson seedless and Flame seedless grapevines the used intercropped crops increased N, K and organic matter (O. M) in the soil, which enhanced vines nutritional status, increased total microbial count, vegetative growth, yield and berry quality. Intercropping with peas plants which increased shoot length, leaf area and N and K in the leaves as well as yield per vine, TSS content and total sugars, while reduced the total acidity in berries and increased total microbial count, dehydrogenase and phosphatase enzymes activity in the rhizosphere. In addition, the economic study indicated that intercropping Thompson seedless and Flame with peas gave higher net profit/ Fadden followed by intercropping Thompson seedless and flame seedless with clover crop.
