Abstract: A field experiment was conducted on a sandy soil at Ismailia Agricultural Research Station, Ismailia Governorate, Egypt during the summer season of 2016 to study the influence of organo-mineral fertilizer application on nodulation status, yield and yield components of peanut. Four different types of composts originated from different raw materials (cotton stalks, rice straw and bagasse) were integrated with different doses of mineral nitrogen (0, 25, 50 and 100%). Application of any type of compost resulted in enhancement of the nodulation status, plant growth, peanut yield and its components. However, application of rice straw and cotton stalk composts attain the highest values of all the studied parameters. Moreover, the synergy between 50% mineral-N and 50% from any type of compost was superior in all the studied parameters. These fertilization patterns may be considered the most effective strategy for reducing chemical fertilizer, conserving soil fertility and supporting the sustainable agriculture system under sandy soil conditions for producing peanut
