The experiment examined the effects of different drip irrigation systems in an O´Neal variety of blueberry (Vaccinium corymbosum L). It was contucted at Zarate (33º 41’ S and 59º 41’ W), Buenos Aires, Argentina. Plants of the experiment were planted in August of 2001, after one year in nursery. The first harvest was realized in October of 2003. The main scope of the experiment was to find the irrigation system which maximized yields. Treatments were: one drip irrigation line with drippers at 40 cm (T1) and two laterals with drippers at 20 cm per row (T2). The experiment was conducted in a completely randomized block design, each one with 5 plants and 5 replications. During the harvest of October and November of 2003, reported yields were 2436 kg ha-1 for the treatment T1 and 4335 kg ha-1 for the treatment T2. Treatments that partially irrigate beds are insufficient to obtain high yields.
