| Abstract | ||
| The present study was carried out during 1999 growing season on one- year old (Hamed) olive plants grown in a sandy soil located at Gabal EI-Dakrour area in 5iwa Oasis. The aim of the present study is to clarify the effed of irrigation regime and nitrogen fertigation rates on vegetative growth and leaf water contents, total chlorophyll and nutrients content of Hamed olive plants grown under Siwa Oasis conditions. The plants were irrigated through a drip irrigation network at rates of 10.2 and 13.6 m3/planVyear according to the climatological conditions. Nitrogen fertigation was applied during the growing season at rates of zero (irrigation water), 70,140 and 210 mg NIL of irrigation water. The obtained results revealed that increasing both of irrigation rate and N fertigation rate significantly increased all vegetative growth parameters i.e., growth rate, average shoot length, plant height, canopy diameter, volume lndex and leaf area. Also, leaf chlorophyll content lind leaf wllter contents were increased markedly due to increasing both irrigation and N fertigation rates. Increasing both irrigation level and N fertigation rate, significantly increased leaf contents of nutrients (N, P, K, Ca, Mg, Fe, Mn, Cu, Zn and 8). Generally, it can be concluded that applying water at rate of 13.6 m3/planVyear and N at the rate of 210 mg/L under drip irrigation system in Siwa Oasis enhanced vegetative growth and improved nutrients uptake for Hamed olive plants. | ||
