Soils in arid and semi-arid regions, such Egypt, have low fertility. To improve the soil fertility and performance of crops, there is an urgent need to manage agricultural process such as plant nutrition is needed for such environments. To discuss the performance of yield under this conditions, two field trials were conducted using four phosphorus fertilizer levels (P1 30, P2 45, P3 60 and P4 75kg P2O5/fad) and three foliar spray with boron levels (B0 tap water, B1 100ppm and B2 150ppm) on peanut. Results indicated that yield components, yield and its quality of peanut were positively (P≤ 0.01) affected by the two factors individually, also had positively (P≤ 0.05) affected by the various interactions on pod yield. The best pod yield was obtained by the bilateral interaction application of P4×B2. Correlation analysis appeared appearance of highly significant with r values between oil and pod yields.
