This experiment was carried out at the nursery of Faculty of Environmental and Agricultural Sciences, El-Arish, North Sinai, Egypt, to study the effect of inoculation with the plant growth promoting rhizobacteria (PGPR), i.e. Rhizobactereien (75g/l) or Nitrobien (65g/l) and the plant extracts namely : Gifert (Algae aqueous extracts),Ginger + Cinnamon extract and Roselle aqueous extract at 10% alone and in combination on the rootability and survival percentage of small high (unrooted) "Hayany" date palm (Phoenix dactylifera L.) offshoots .Results showed that, the highest rooting and survival percentages were observed with Rhizobacterien inoculated offshoots than Nitrobien inoculated ones. Moreover, treating them offshoots with Gifert (Algae extract) gave the highest values of rooting and survival percentages of small offshoots, followed by Roselle plant extract and Ginger combined with Cinnamon aqueous extract, respectively. The highest values of rooting and survival percentages were observed with Gifert (Algae extract) treated offshoots and inoculated with Rhizobacterien, while small offshoots treated with Nitrobien X Ginger and Cinnamon had the least values in this respect. The other interactions came in between them in this concern.

This study aimed to examine the effect of organic sources such as fish scrap, goat manure and olive pomace, type of application (surface and trench) and bio-fertilizer applications (Nitrobein or Rhizobacterein) on flowering, fruit yield and fruit quality of Earligrande peach trees during the two consecutive seasons of 2013/2014 and 2014/2015 at the private Farm at El-Kharafen village in Rafah district, North Sinai Governorate, Egypt. Results indicated that organic fertilization treatments increased number of flowers per shoot, fruit set percentage, total yield, fruit volume and firmness, Vitamin C and total soluble solids (TSS) in both seasons. The fish scrap treatment produced the highest value of each yield measurement, followed by goat manure treatment, then olive pomace treatment compared with nonfertilized trees (control). On the other hand, trench application achieved very significant effect on tree yield (Kg/tree), fruit weight, fruit volume and firmness compared with surface application in both seasons, But surface application recorded the highest value for each of Vitamin C and total soluble solids (TSS). Also, results showed that Rhizobacterein fertilizer recorded the heights value for each of fruit weight, fruit volume and firmness, Vitamin C and total soluble solids (TSS). Finally, additive the fish scrap (about 2.77 Kg. tree -1 . Year -1 ) with Rhizobacterein fertilizer (50 g/tree) in trench application gave the highest fruit properties, fruit yield and improve "Earligrande" peach fruit quality properties in the same experiment conditions.

Embryo, Shoot tip and one node cutting from bitter and sweet almond are excised; sterilized, and cultured on Murashige & Skoog (MS) medium. Also, different cytokinin types were evaluated. The obtained results showed that culturing of embryo on free MS medium was effective in enhancing establishment stage of bitter almond. However, sweet almond was enhanced by MS medium supplemented with BAP. Meanwhile, adding 1.0 mgl -1 BAP for bitter almond and 2.0 mgl -1 BAP for sweet almond encouraged the highest proliferation.
