Abstract

This investigation was carried out to study the effect of irrigation intervals and phosphorus fertilizer on vegetative growth and oil yield, at Farm of Medicinal Plant, Dokki during 1992-1993 and 1993-1994 sea­sons. Three levels of irrigation intervals (every one, two and three weeks) and three levels of calcium superphosphate 0,150 and 300 Kg/ Feddan were also used. The results showed that 150 Kg superphosphate per feddan, and weekly irrigation caused increases in the number of urn­bels, weight of seeds and percentage of volatile oil. It could be recom­mended to use 150 Kg super phosphate / Feddan and irrigating the plants every week.
