Abstract. Cucurbita pepo L. seeds are very important in nutrition and pharmaceutical industries due to high amounts of oil. To investigate the effects of biochar (zero, 5, and 10 tons per hectare) and foliar spraying with zinc nanoparticles (zero, 2, and 4 milligrams/ litter), an experiment was conducted as factorial based on randomized complete blocks design, in the Farm. Fruit number and leaf Zn content were increased at 5 and 10 t/ha of biochar with both nano zinc foliar spray. Ten t/ha biochar treatments with both levels of nano Zn increased seed number per fruit, fruit yield, biological yield, harvest index, and plant oil yield. Five t/ha biochar with 4 mg/L of nano zinc and 10 t/ha biochar with foliar spraying with both nanoparticle concentrations increased hundred seed yield, biological yield, and chlorophyll index in the plant. The top amounts of phenolic content were observed in 5 and 10 t/ha biochar with 4mg/L of zinc nanoparticle spray. The relative water and anthocyanin content increased in 10 t/ha biochar. Overall, theresults of this study showed that the use of 10 t/ha biochar and foliarspraying of 2 and 4 mg/L zinc nanoparticles increased the yield and physiological characteristics of the plant.
