The effect of organic manures on growth, nutrient status and fruiting of Roumi Red grapevines was studied during 2004 and 2005 seasons. The study was carried out at the experimental orchard of Qena Agriculture Faculty, South Valley University, Egypt. Two organic manures namely, filter mud cake and  chicken manure were used either alone or combined with an inorganic source of nitrogen (N). Organic manures were applied at 0.0, 50, 75 and 100% of the recommended dose of the inorganic N fertilization (80g/vine/year). It is evident from the obtained results that applying organic N either alone or in combination with the inorganic form was very effective in improving growth, yield, leaf nutrient composition and berry quality of vines, compared to the complete application of N as an inorganic form. The increment was associated with increasing the amount of each organic manure. Organic N fertilization alone was superior to inorganic one in this respect. The obtained results also showed that applying 75 or 100% of the N requirements for Roumi Red grapevines in an organic form was very useful in improving yield and fruit quality. In addition , it decreases the environment at pollution problems.
