| Abstract | ||
| The present work was carried out in vegetable private farm at El-Kassasein Distract, Ismailia governorate during two successive winter seasons of 2008/2009 and 2009/2010, to evaluate the effect of foliar spray with both humic acid (HA) at 0, 0.1and 0.2 % and green microalgae extract (GMAE) of Scenedesmus sp. at 0, 0.1 and 0.2 % as well as their interactions on nutrient content and uptake as well as photosynthetic pigments. Consequently, growth and yield of garlic (sids-40) under sandy soil conditions using drip irrigation system. Spraying garlic plants with HA at 0.2 % or with GMAE at 0.2 % recorded the maximum values of N,P and K uptake in bulb and N,P and K total uptake, chlorophyll a, b, total (a+b) and carotenoids, total dry weight, average bulb weight , yield of grades 1 and 2 and total yield/fed. without significant differences by spraying with GMAE at 0.1 % with respect yield and its components. The interaction between spraying of garlic plants with HA at 0.2 % and GMAE at 0.2% was the best interaction treatment for enhancing N,P and K total uptake, total dry weight, while average bulb weight , yield of grades 1 and 2 and total yield/fed. were increased with the interaction between HA at 0.2 % and GMAE at 0.1 or 0.2 % . Conclusively, from foregoing results of this study, it could be concluded that spraying of garlic plants with HA at 0.2 % and GMAE at 0.2% increased mineral uptake, plant growth and total yield of garlic under sandy soil conditions. Keywords : Garlic, humic acid, green microalgae extract, NPK uptake and total yield.
