Resumo: The objective of this work was to evaluate the performance of different configurations of subsurface drip irrigation (SDI) by measuring coffee (Coffeea arabica L.) leaf water potential. Six treatments of drip irrigation combining two drip emitters spaced at 0.50 and 0.80 m, with three drip placement depths: 0 cm (soil surface), 0.10 m and 0.20 cm. The combined treatments were: T1 (50 – 0), T2 (50 – 10), T3 (50 – 20), T4 (80 – 0), T5 (80 – 10) and T6 (80 – 20). Leaf water potential was measured using a Scholander pressure pump at predawn and during the day. Both surface drip irrigation treatments showed a lower predawn leaf water potential. The treatment that presented better performance with higher water potential values was T2. Another fact observed was that treatments with wider spacing between emitters (T4, T5 and T6) always presentd higher water stress than other treatments, mainly in the period when irrigation was suppressed (June, 25th to September, 14th).

The treatment that presented better performance with higher water potential values was T2. Another fact observed was that treatments with wider spacing between emitters (T4, T5 and T6) always presentd higher water stress than other treatments, mainly in the period when irrigation was suppressed (June, 25th to September, 14th). Objetivou-se com o presente trabalho avaliar o desempenho de diferentes configurações de instalação de gotejadores, monitorando-se o potencial de água em cafeeiros (Coffeea arabica L.). Foram implementados 6 tratamentos de irrigação por gotejamento, combinando dois espaçamentos entre emissores, de 0,50 e de 0,80 m, sendo os tubo gotejadores instalados na superfície do solo (0) e na subsuperfície, a 0,10 e a 0,20 m de profundidade, respectivamente T1 (50 – 0), T2 (50-10), T3 (50 – 20), T4 (80 – 0), T5 (80 – 10) e T6 (80 – 20). Para medição do potencial hídrico foliar na alvorada e ao longo de dias selecionados, foi utilizada bomba de Scholander. Pelos resultados, verificou-se que os tratamentos com gotejadores na superfície resultam em menor potencial hídrico foliar no período da antemanhã. Notou-se que o tratamento que proporcionou maior potencial hídrico foliar ao cafeeiro foi o T2. Nos tratamentos T4, T5 e T6, que tinham maior espaçamento entre emissores, foi observado maior estresse hídrico que os demais, especialmente no período de suspensão das irrigações (25/6 a 14/9).
