EFFECT OF PLANT GROWTH PROMOTING RHIZOBACTERIA AND SOME PLANT EXTRACTS ON ROOTABILITY OF AERIAL HAYANY DATE PALM OFFSHOOTS B- VEGETATIVE GROWTH AND ECONOMIC REVENUE
Sinai Journal of Applied Sciences
A pot experiment was carried out at the nursery of Faculty of the 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 at 75g and Nitrobien at 65g and some plant extracts namely Gifert (Algae aqueous extracts), Ginger + Cinnamon extract and Roselle aqueous extract at 10% alone and/or in combination on the vegetative growth and economic revenue and profit of small high
... rofit of small high (unrooted) "Hayany" date palm (Phoenix dactylifera L.) offshoot (suckers). Results showed that, the highest vegetative growth and economic revenue and profit were gained by Rhizobacterien inoculated offshoots than Nitrobien inoculated ones. Moreover, treating the offshoots with Gifert (Algae extract) gave the highest values of vegetative growth and economic revenue and profit of small offshoots, followed by Roselle plant extract and Ginger + Cinnamon aqueous extract, respectively. The highest values of vegetative growth and economic revenue and profit were observed with Gifert (Algae extract) treated offshoots and inoculated with Rhizobacterien. While those treated with Nitrobien combined with Ginger + Cinnamon had the least values, the other interactions came in between.
