<br/><br/> This study was undertaken during 2014 and 2015 seasons on Flame eedless grapes to investigate the beneficial effects of foliar application of some bio-stimulants in relation to the conventionally applied GA3 and at the same period. The following bio-stimulants were used: a) microbiota [bacillus megaterium, bacillus subtilis, azospirillum lipoferum, yeast (Saccharomyces cerevisiae)] b) algae [scenedesmus obliquus, spirulina platensis and seaweed (ascophyllum nodosum)]. Parameters assesed were, crop and its quality attributes, vegetative growth, and leaf nutritional status. The obtained results showed that the majority of these responses were, significantly higher than control, and some than the standard GA3 treatment. Generally, using seaweed extract of ascophyllum nodosum at 4g/L led to clear enhancements in the majority of the tested vegetative and fruiting parameters of flame seedless grapevines
