This work aims to evaluate partial root drying technique for lemon cv. Tahiti under conditions of climate and soil of North of Minas Gerais in sandy soil. The experiment followed a random block design with nine treatments and four replications. The partial root drying was accomplished by turning on and off water emission from lateral lines that were located at both sides of each crop row of the plot at different time intervals (7 and 15 days). Treatments consisted of irrigation deficits of full irrigation (FI), with application of 75% of FI as partial root drying at intervals of 7 days (T1) and 15 days (T2) in all phenological phases; application of 50% of FI as partial root drying at intervals of 7 days (T3) and 15 days (T4) in all phenological phases; application of 75% of FI during phases I and II and 50% of FI during phase III, as partial root drying at intervals of 7 days (T5), 15 days (T6) in all phases; application of 75% of FI during phase I and 50% during the remaining phases, as partial root drying at intervals of 7 days (T7) and 15 days (T8). Results showed that irrigation with partial root drying management may be done with any of the treatments. The larger yields and water use efficiencies were obtained for treatments T7 and T8 (reduction of 25% total irrigation every 7 or 15 days during flowering followed by reduction of 50% of total irrigation every 7 or 15 days in phases II and III). The variance analysis did not detect effect of treatments on the physiological variables leaf transpiration, stomatal condutance, temperature and relative water content. A reduction of transpiration and stomatal condutance was detected for treatments T1, T2, T3 and T4 related to T9 in the phase MenosThis work aims to evaluate partial root drying technique for lemon cv.
