ASPECTS CONCERNING THE WATER REQUIREMENT IN VINEYARD AGRO-ECOSYSTEMS FROM SEMI-ARID AREAS FROM ROMANIA PUBLISHEDMarius Popescu, Aurora Ranca, Zoia Prefac, George Marius Cracu
The aim of this paper is to emphasis the aridity conditions from South and South-Eastern Romania and to detail the relations between water and soil-plant-atmosphere system with application in vineyards agro-ecosystems. Of climatic elements by presenting the temperature and precipitations, but also the specific characteristics for drought and aridity and Penman-Monteith reference evapotranspiration. Also are describe the correction coefficients of agricultural crops used in irrigation technique, the optimal real consumption of water for vineyards cultures and is emphasized the territorial repartition of water necessary for these. In order to produce qualitative grapes, the vineyards cultures from semi-arid areas from south and south-eastern of Romania require a greater quantity of water, especially within the summer months, July and August.
