Abstract
In sustainable viticulture, green manure represents a safe and non-polluting way to bring large quantities of organic matter into the soil. Tilling annual plants between rows and using them as green manure has a favourable influence on the physical, chemical and biological features of the soil, without affecting the growth and fructification of the vine. The possibility of using this fertilization system is limited by the rainfall conditions, which must be of about 600 mm annually, of which at least 300 mm in the vegetation period, distributed as useful rain (10 mm). The main objective of this article was the use and influence of green manure fertilization on Chasselas Dore grape vine variety, grown in the temperate continental climate of the northeastern part of Romania (Iasi vineyard). The research showed that compared to the standard cultivated field, the use of green manure led to a faster maturation of the grapes and a slight decrease in grape production, but an improved quality, increase of assimilatory pigment contents and photosynthetic capacity, a slight decrease of disease attack and the increase of the carabids predator population. All these results proved that the green manure fertilization system can also be practiced in the areas where the annual precipitation level is below 600 mm, without significant effect on the production and quality of the grapes.
