The objective of this work was to evaluate the effect that different irrigation depths on the growth and crop production of jambu plants. The treatments consisted of five irrigation depths corresponding to 40%, 70%, 100%, 130% and 160% of field capacity. The experimental design was a randomized blocks with four replications. The plot consisted of four plants in separate pots. For comparison of treatments, at 27 days after transplantation, the following variables were analyzed: plant height (PH), stem diameter (SD), leaf fresh matter (LFM), stalk fresh matter (SFM), root fresh matter (RFM), inflorescence fresh matter (IFM), leaf dry matter (LDM), stalk dry matter (SDM), root dry matter (RDM), inflorescence dry matter (IDM) and water use efficiency (WUE). The effect of irrigation depths was significant for the analyzed variables, except for the SD and IDM. There was a quadratic behavior of the variables in relation to the applied irrigation depths. The maximum values of each parameter were obtained with irrigation depths close to 100% field capacity. Although the efficiency of water use was higher for the irrigation depth of 40% of field capacity, It is most recommended to use the irrigation depth at 100% of field capacity, because it provided the best answers of the variables analyzed.
