English. Rosemary is one of the most important medicinal plants. In order to study the effect of plant growth promoting rhizobacteria (PGPR), Azolla compost and Azolla biochar on dry matter, nutrient uptake, physiological parameters and essential oil of rosemary, a greenhouse experiment was conducted in a completely randomized design with 6 replications. Treatments consisted of T1 (control), T2 (1% (1 g 100 g-1 dry soil) Azolla compost), T3 (1% Azolla biochar), T4 (PGPR (P. fluorescens)), T5 (1% compost + PGPR) and T6 (1% biochar + PGPR). Results indicated a significant enhancement of dry matter, nutrient uptake, photosynthetic pigments, carbohydrate, flavonoid and essential oil contents of rosemary influenced by organic fertilizers compared to control, particularly with co-application of PGPR + compost or biochar. Proline content decreased in all treatments in comparison with control. Results indicated positive impacts of PGPR, compost and boichar of Azolla on rosemary production by increasing nutrient uptake and protecting chlorophyll from degradation and enhancing its content in leaves.

In einem Gewächshausversuch wurde der Einfluss von Bio-Düngern wie PGPR, Compost und Biochar aus Azolla-Algen auf Ertrag, Nährstoffaufnahme und diverse Inhaltstoffe der Gewürzpflanze Rosmarin geprüft. Alle Behandlungen zeigten im Vergleich zu den Kontrollen signifikante Effekte auf Ertrag, Nährstoffaufnahme und Gehalte an Chlorophyll, Carotinoiden, Flavonoiden, Kohlenhydraten, Prolin und essentielle Ölen.
