چکیده

This investigation was carried out at the experimental farm of Medicinal and Aromatic plants Research Department, Horticulture Research, Dokki, Giza during two successive seasons of 2009/2010 and 2010/2011.The research aimed to study the effect of compost rates (2,4and 8 ton/fed) and some biofertilizers (Azotobacter Chroococcum, Bacillus megaterium, Bacillus circulanse) alone or all strains in a mixture with or without compost on growth, yield, essential oil productivity and chemical composition of Rosmarinus officinalis, L. plants. The results showed that, in both seasons, the highest plant height; number of branches; plant fresh and dry weights, oil percentage and yield in fresh herb and total carbohydrates were given by adding compost at 8 ton/ fed compared to other compost treatments; Azotobacter Chroococcum (AZ) + Bacillus megaterium (B1) +Bacillus circulanse (B2) compared to other biofertilizers treatments; compost at 8 ton / fed + Az+B1+B2 compared to other combination treatments.
