| Abstract | ||||
| Two experiments were consummated at the Experimental Farm, National Research Center (NRC), Dokki, Cairo, Egypt during two succes-sive seasons of 2004/2005 and 2005/2006 to eval-uate the effect of natural products as a source of some important elements such as rock phosphate as a source of phosphorous and feldspar mica as a source of potassium with biological potassium phosphorous fertilizer or biological potassium fertilizer (Silicate bacterium) at different levels (0.0, 25, 50 and 100 g/L) on Ruta graveolens L. plant instead of the chemical fertilizes. Adding biological fertilizer with feldspar or rock phos-phate improved vegetative growth characters such as plant height (cm), branches number/ plant, fresh and dry weights of different plant parts i.e. leaves, stems and roots (g/plant), in addition to some chemical constituents as essential oil, total flavo-noides, P, K, Fe, Zn and Cu content. On the other hand, the main constituents of essential oil and N content were decreased compared with adding recommended chemical fertilizers. | ||||
