Abstract
The effects of two drip irrigation systems combined with three levels of calcium (Ca) and potassium (K) fertigation on Vaccinium corymbosum ‘O´Neal’. The study site was in the south of Concordia, Entre Rios province, Argentina, in a sandy soil.
Irrigation treatments were based on 0.8 or 1.2 Kc and fertigation treatments were 0, 1, and 2 applications of Ca plus K. They were sprayed with aminoquelant Ca and K. The doses were 40 cc of each per 100 liters of water.
They were applied during August and September.
The number of berries per plant varied from 342 to 466 between treatments and the weight per berry varied from 1.36 to 1.73 g per berry.
Two years after planting, treatments combining 1.2 of Eto, and maximum rate of Ca and K had the highest yield (3.160 kg ha-1).
