The concept of sustainable viticulture increasingly involves among others the current restrictions on the use of chemicals in viticulture and finding alternatives for their replacement without affecting the quantity and quality of grape production, which is responsible to these studies. In this research has concerned the replacement of conventional fertilization with chemical fertilizers, by using of green fertilizers in several variants for fertilization bearing vines. In the western area in recent years began to have concerns regarding alternatives to traditional technology, but they limited themselves to an alternative grassing intervals without taking into account the use of green fertilizer plant by intake of nutrients to the ground partially or totally replace chemical fertilizers. Experimental variants were found in cultivation in the interval between rows of vines of : V1 - Borceag, V2 - vetch, V3 - Sainfoin. Were left rooted to the line protection strips of 40 cm. I followed for three years (2007-2009) the effect of experimental variations on wood maturation, bud viability, maturation of the grapes, the quality and quantity of production in some varieties of wine grape grown in the vineyard Buziaş-Silagiu. The results were encouraging, all variants providing numerous advantages compared with control version (use of complex fertilizers). In the future importance of these types of research will become increasingly important with increasing environmental concerns and obtain wine products as healthy for human body. Using green manure allowed obtaining of products with high quality, with a lower content in chemical elements and at the same time helped to improve of soil physical and chemical characteristics and reduce the harmful impact on the environment. Research has been possible and thanks to their support of the research project: Development of some models of advanced viticultural technologies in accordance with the pedoclimatic conditions, the varietal assortments and sustainable viticulture principles, PNII-IDEI, code 1128, No. 355/01.10.2007, Project Manager: Prof. dr.
