Abstract

The effect of intercropping Superior grapevines with three intercrops namely, clover, fenugreek and bean under different levels of N (40 , 60, 80 and 100 g/ vine) on leaf area, N, P, and K content, yield as well as physical and chemical characters of the berries was investigated during three seasons (2005, 2006 and 2007) in Assiut governorate.
Results   showed  that  intercropping  the  vines  with  clover, fenugreek and bean, was favorable in a descending order and enhancing leaf area, percentages of N, P and K, berry set, yield as well as physical and chemical characters of the berries. Intercropping governed effectively the optimum level of N required for obtaining an economical yield.
The best results with regard to yield and quality of Superior grapes were obtained when the vines were intercropped with clover and fertilized annually with N at 60 g/vine
