A field experiment was conducted during seasons of 2008 and 2009 on Flame Seedless grapevines. The vines were 12-years-old, cultivated at 2 x 2.5 m apart, trained as cordon system, and grown in a clay soil, and drip irrigation system was used, to study the effects of foliar applications of different concentrations of Goemar BM 86 and Acadian extracts on nutrient uptake, growth and yield of Flame Seedless grapevines. The foliar spray was replicated three times at four concentrations (0, 0.5, 1 and 2 %) of seaweed extracts. Foliar applications of seaweed extract significantly enhanced yield parameters. The highest yield weight was recorded with applications of 1 % Acadian extract, followed by 2 % Goemar extract that resulted in 59 % and 39 % increases, respectively compared to the control. The maximum fruit quality was achieved with 2% Goemar extract application. Improved nutrient uptake was also observed with seaweed extract applications. Thus, foliar application of Acadian extract could be a promising option for yield enhancement, and Goemar extract for fruit quality.
