RESUMO

Strawberry yield and quality was evaluated after drastic pruning (second cycle), under different soil water tensions, drip irrigation in edaphoclimatic conditions at south of Minas Gerais. The experiment was conducted on beds at a greenhouse, located at Engineering Department, Federal University of Lavras (UFLA), from April to December of 2010. An experimental design was in randomized blocks with three replicates. The treatments were composed of six different soil water tension, 15, 25, 35, 45, 55 e 70 kPa. Results obtained allowed to verify that to higher values of: total and commercial fresh weight of fruits per plant, total and commercial number fruits per plant and total and commercial yield, it is necessary to irrigate when soil water tension gets approximately to 15 kPa, at 0.15 m deep. Commercial average fruit mass and noncommercial fresh weight of fruits per plant, were not reduced under different soil water tensions applied. The strawberry quality characteristics; total soluble solids and pH, presented higher values with tension of 70 kPa, however the total acidity was not affected by different soil water tensions.
