The optimistic Toshky National Project is representing strong challenge to cultivate new reclaimed lands under stress ecological situa­tion. The aim of this research is to compare competition between natural rock phosphate and super phosphate fertilizers on single crop as well as Intercropping tomato with faba bean, most important legume fool crop; for utilizing land equivalent per water unit an experiment was carried out for two years during 2001/2002 and 2002/2003 seasons, at the South Valley Agriculture Research Station, Toshky. in a randomized complete block design. The treatments included phosphate sources (natural rock phosphate and super phosphate) as well as doses. Transplanting dates for tomato hybrid (castle rock) were on i^sland 7^th September In 2001/ 2002 and 2002/2003 seasons, respectively. Sowing dates of faba bean (variety Giza 40) were 15^th and 22^nd October in two seasons, respec­tively. Tomato seedlings were transplanted on one side for each lateral 50 cm between drippers. Fabe bean seeds were planted in hills spaced 10 cm between hills, one plant per hill. The obtained results indicated that yield and yield components of gibe bean were decreased by intercropping faba bean with tomato as compared with faba bean grown alone, in both seasons. The response of seed yielcUld and yield components to phosphate levels was linear be­tween zero and 60 Kg P205/f 0. Intercropping tomato with labs bean compared with grown tomato separated in both seasons decreased to­mato fruits yield and marketable traits yield. Also, results indicated that in all studies of tomato characters improved with increasing phosphate fertilizer, except culls percentage which decreased with increasing phos­phate fertilizer compared to control in both seasons. Total yield and mar­ketable yield increased with increasing mixed phosphate from [IS Kg P2⁰5 (NP) + IS Kg P205 (SP)) to [45 Kg P205 (NP) + 45 Kg P2⁰5 (SP)) compare to control In both seasons. The highest value for Land Equivalent Ratio (LER) was 1.91 and 1.99 lot the treatment using mixed phosphate [45 Kg P205 NP) + 45 Kg P205 (SP)) in the first and second seasons, respectively. It may be worth mentioning that intercropping to­mato with faba bean has maximized utility of irrigation water by saving 31 % compared to separate treatments.
