CROP WATER STRESS INDEX AND SAP FLOW IN YOUNG CACAO TREES UNDER CONDITIONS OF LOW ATMOSPHERIC WATER DEMANDABSTRACT: New agricultural technologies, especially irrigation, make it possible to increase the productivity of the cocoa crop. The objective of the present work was to evaluate the leaf temperature and transpiration of young cacao trees submitted to water restriction in the soil, in conditions of low demand of water by the atmosphere. The experiment was conducted in a greenhouse at the Federal University of Bahia Recôncavo. Sap flow measurements were
