Abstract: The field experiment was conducted two successive summer seasons of 2018 and 2019 at Ismailia Agricultural Research Station, Egypt to evaluate the effect of Olive mill wastewater (OMW), Biochar and NPK fertilizers rates on some sandy soil properties and peanut (Arachish ypogaea) productivity in sandy soil. A randomized complete block design was used. The results indicated that soil pH and EC was not significantly affected in the soil treated with Olive mill wastewater (OMW) and biochar. There are positive significant effects on nutrient availability (NPK) in both seasons by using biochar and olive mill wastewater in soil as well as their content in peanut plants. The application of OMW can improve soil quality indices (nutrients (N, P, and K), organic matter, pH, total porosity, bulk density and plant growth performance. The Olive mill wastewater (OMW) and Biochar application increased plant height, No. of branches, No. of pods, protein (%), seed oil (%) and seed yield (ton fed- 1) as well as NPK content in peanut plant.
