Abstract:

In sustainable viticulture, green manure represents a safe and non-pollunting 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). This study article had as main objective the use and influence of green manure fertilization in the case of the Chasselas Doré grape vine variety, grown in the temperate continental climate, with excessive accents from the north-eastern part of Romania (Iaşi vineyard). The research has shown that, compared to the standard version (cultivated field), the use of green manure led to a faster maturation of the grapes, a slight decrease in grape production, but an increased quality, the growth of assimilatory pigments content and photosynthetic capacity, a slightly decrease of disease attack and the increase of the carabids population. All these prove that the green manure fertilization system can also be practiced in the areas where the annual precipitations level is below 600 mm, without significant effect on the production and the quality of the grapes.
