The management of irrigation with partial root drying (PRD) was tested in orchard of ‘Tahiti’ lime in semi-arid conditions of Iaçu-BA. Six treatments were evaluated: T1, T2, T3 and T4 received 50% of ETc, T5 -100% and T6 - 75%. A microsprin-kler was installed per plant and its location to the plant was changed by wetting opposite sides of the root system alternately for treatments with a water deficit of 50%. The interval for changing the wetting locations was 7, 14 and 21 days for T1, T2 and T3, respectively. Irrigation was fixed in just one side for the treatment T4. Irrigation was fixed with 100% of Etc as water supply in the control treatment, T5. In case of T6, one microsprinkler per plant worked during 21 days, followed by two emitters per plant which worked during the same interval along crop cycle. There was no statistical difference (p<0.05) by Scott Knott test for the variable fruit production. The treatments T5 and T6 obtained the highest yield with 23.16 and 22.49 t?h-1, respectively. Treatments with deficit had average production reduced 30%. Switching sides of irrigation had no benefit over treatment with the deficit in only one side. Although there was no statistical difference in efficiency of water use, physiological indicators showed that the treatment in water deficit developed mechanisms to reduce transpiration. |
