A field experiment was carried out at Green Land for Agriculture and Soil Reclamation (GLASR) Company's field (30°36'45.78"N, 31°57'07.55"E), Salheya, Sharkia Governorate, Egypt. On the basic of fertilization management program applied by the company (control), Three-factors computer model was implemented to study the combination effect of compost, gypsum (23% Ca and 17.5% S) and phosphatic fertilizers (ordinary superphosphate (6.5% P) and phosphoric acid (37% P)), on some soil properties and yield attributes of peanut plant. Results revealed an improvement in soil N and P availability and remarkable increases in most of peanut Yield attributes as a result of compost, gypsum and phosphatic fertilizers application compared with the management and fertilization program used by GLASR Company. Data indicated that the most revenue treatment for peanut production in Salheya, Sharkia Governorate consists of 40, 50 and 10% from the maximum dose of compost, gypsum and phosphatic fertilizers, respectively which equal to 20m3 compost, 108.7kg gypsum, 1Okg ordinary superphosphate and 1 .83L phosphoric acid/faddan.
