The present experiment was conducted during 2004/2005 and 2005/2006 seasons in the Farm of Ornamental, Department, Fac. Of Agric. Cairo University, Giza, to study the effect of some bio and chemical fertilizer on growth and yield of anise plants.
The plants were grown in plastic pots (30 cm-diameter) using Mycorrhiza and Phosphorene individually or in combinations with or without chemical fertilizers. Superphosphate was added before sowing, while ammonium sulphate and potassium sulphate were dressed three times at 21 days intervals in both seasons. The chemical fertilizers were added with the bio fertilizer at 3 rates: NPK (1) at (9, 6 and 3 g/ pot), NPK(2) at (15, 12 and 6 g/ pot) and NPK(3) at (30, 24 and 12 g/ pot).
Data were recorded on growth, fruit yield, oil percentage, and oil yield and oil composition.
The following results were recorded:
1- In general, anise plants were significantly responded to bio fertilizer with or without chemical fertilizer.
2- Phosphorene increased the vegetative growth expressed as (plant height, number of branches, fresh and dry weight). Also, the vegetative growth was gradually increased with increasing the rate of NPK fertilizers.
3- Mycorrhiza increased the vegetative growth, and increased gradually with increasing the rate of NPK fertilizers.
4- Phosphorene plus Mycorrhiza with the third level of NPK gave the great stimulation of vegetative growth such as (plant height, number of branches, fresh and dry weight).
5- Bio fertilizers (Phosphorene and Mycorrhiza) each alone or together, with or without NPK produced the highest fruit yield.
6- The two bio fertilizers with NPK (3) gave the highest fruit yield, oil percentage, oil yield, with the highest anethole content.
