- Abstract
In the coffee production, Brazil stands out as the world's largest producer, but its productivity is negatively affected by drought, which makes production dependent on water supplementation. This work aims to determine water stress and the development of Conilon coffee in different irrigation depths. The experimental design consisted of randomized blocks with three replicates, distributed in five treatments, the irrigation depths of 0, 25, 50, 100 and 125% of ET0 -. Each plot was constituted of six plants, being the first two plants of each block considered border. The leaf water potential was is determined by measuring leaf turgor pressure using the Scholander pump in a plant per block and by treatment. The plant height, stem cross-section and crown diameter were evaluated in three plants per block using a graduated ruler and pachymeter. The values for leaf water potential performed in the morning ranged from -0.15 to -1.18 MPa and, for noon, from -1.17 to -2.3 MPa. The irrigation depths equivalent to 100 and 125% of the ET0 presented higher values throughout the development of the culture until the moment of the evaluation.
