Experimental layout following a completely randomized block design with four blocks and three irrigation treatments (T0: full irrigation, T1: moderate irrigation, T2: no irrigation) established in a Tempranillo, vertically shoot positioned vineyard located in La Rioja (Spain). Close-up of a given field replicate, involving three adjacent rows, of which the middle one was monitored with the NIR spectrophotometer, and three vines per replicate were randomly selected for the measurement of the stem water potential (ψs), one per each sub replicate unit.
