EFFECT OF THE BIOSTIMULANT FOLIAR ADDITION OF MARINE ALGAE ON 'O'NEAL' PRODUCTION

N. Loyola, C. Muñoz
In the 2003-2004 fruiting seasons in Retiro, El Lucero county, Maule, VII Region of Chile, an application of a marine algae extract known as Ascophyllum nodosum, whose commercial name is Ekologik®, was evaluated by applying several different use rates to the canopy of Vaccinium corymbosum ‘O’Neal’ southern highbush blueberry in order to evaluate its impact on total weight, average weight, equatorial diameter and soluble solids content. The marine algae extract was applied during full bloom and fruit set. Four treatments were conducted: T0, pure water (control); T1, 280 ml/hectare; T2, 140 ml/ha; and T3, a 420 ml/ha. The experimental design comprised sub-sampling blocks with three replications of three uniform and healthy plants per treatment. Total and average fruit weight did not differ significantly among treatments, but a trend toward increased average weight of berries was observed. Equatorial diameter, caliper and soluble solids content were increased significantly by marine algae extract treatments.
