The study was conducted to determine the yield of varieties of peanut (Arachis hypogaea L.) as influenced by different rates of synthetic chemicals nutrients. NSIC Pn 08 and NSIC Pn 10 were used in the study. This study was conducted at the soil and climatic condition of Mindanao State University Buug Campus Field Laboratory, Zamboanga Sibugay, Philippines with an average temperature of 27 0C. The experiment was laid using Split – Plot in Randomized Complete Block Design (RCBD) with eight combined treatments and replicated three times. An area of 227.81 m2 including alley ways was divided into 24 plots, each plot measured 1.5 m x 5 m. There were two factors used in the study, the varieties and rates of N2, P2O5, K2O fertilizer. Four seeds were planted per hill with the distance of 20 cm between hills and 70 cm between rows fifteen (15) days after planting. Thinning was done and leaving only one plant. There were two rows per plot and each plot has 46 hills with total of 1,104 plants. Different rates of complete fertilizer was drilled planting holes two days before planting at a rate of F1 1.63 grams, F2 2.44 grams, F3 3.26 grams of complete fertilizer. The result revealed that the average weight of pods in grams per hill per plot per treatment showed that there was a significant difference among varieties. In addition, average number of pods, average number of seeds per hill per plot per treatment and total number of seeds per plot per treatment showed that there is no significant difference among the different varieties, different rates of complete fertilizer and on treatment combinations.Keywords: Peanut, Split-Plot in Randomized Complete Block Design (RCBD), Varieties, NPK Fertilizers
