Abstract
The use of fertigation in vineyards is influenced by physical properties of soils and plant development, being critical knowledge of soil water content and plant water status. The objectives are to analyze the effects of fertigation on the production, maintaining a homogeneous quality-quantity relation, using a pair of irrigation systems. The methods used have been the water activity meter (WAM) for leaf water potential and time domain reflectometry (TDR) for monitoring water content in the soil. The results show that in the four years studied the vineyards of treatment �subsurface drip irrigation� show a better �water status� in both soil and plant, as opposed to �drip irrigation�, and in both versus control treatment �without irrigation�. We conclude that the application of nutrients through irrigation water does not mean altering the stressful situation that requires the vineyard, but the irrigation water reduces the water stress that the plant is subjected (without irrigation), without influencing the quality parameters of grape must.
