Abstract: In the 2017 and 2018 summer seasons, two field experiments were conducted at Ismailia Governorate, Egypt, to evaluate the effect of adding organic amendments combined with 50% of the recommended 100 kg ha-1 of mineral-N fertilization Ammonium nitrate (330 g N kg-1 ). The five organic sources were three types of biochar and two types of compost at a rate of 24 Mg ha-1 on peanuts (Arachis hypogaea L. Giza 6) grown on a sandy soil. Available N, P, K, Fe, Mn, and Zn concentrations in the soil after harvest increased due to the additional treatments, and the highest concentrations were due to Compost B (town refuse residues)+50 kg N ha-1 . Electrical Conductivity (EC) and soil pH decreased due to compost addition but slightly increased owing to biochar addition. The highest chlorophyll, protein, and oil contents of 42.8 mg g-1 , 226 g kg-1 , and 448 g kg-1 , respectively, were obtained due to addition of 50 Kg N ha-1 AN + Compost B. Generally, the addition of N fertilization 50 kg N ha-1 combined with compost had a favorable effect in improving soil properties and increasing peanut, oil, protein content and nutrient uptake as compared to other treatments.
