In five Romanian vineyards, in 2013-2014 period was experimented organic system growing on  grape varieties for wine representative for each area, here are applied organic growing technology in parallel with the conventional (control). White varieties studied are: Chardonnay (Murfatlar and Valea Calugareasca), Sauvignon blanc and Muscat Ottonel(Tarnave), Feteasca regala (Tarnave, Bujoru and Copou-Iasi). Red varieties are Cabernet Sauvignon (Murfatlar and Valea Calugareasca) and Merlot (Bujoru).

Concerning evolution of main climatic factors for the years 2013-2014 it is show that the annual average air temperature increase compared with the average of the years 1991-2010; is observed an increasing in mean annual temperature, mean temperature during the growing season and the value of sum of sunshine hours. The water regime was kept constant, registering values close to the annual average, both during the growing season and at entire year.

The weeds spectrum is represented both by dicotyledonous as knotweed (Polygonum aviculare), Veronica (Stellaria media), news (Amaranthus retroflexus), bindweed (Convolvurus arvensis) and monocotyledonous as grass thick (Cynodon dactylon).

Concerning the phytosanitary status, at Murfatlar were registered problems with oidium attack, with all main disease at Dealu Mare and with downy mildew at Bujoru. In all areas the pest has been found are: grape mouth (Lobesia botrana) and spiders (Tetranichus sp.). Schemes of treatments focused generally on substances bassed on copper and sulfur to combat diseases and for pests have been used pheromonal traps or other certified organic products.

The grapes harvest was lower in organic plots with till 25%; their quality being close at both growing variants.
