Objective: In this study investigated effects of different amounts of pelleted manure with urea and micro elements on yield and seed quality of medicinal plants, pumpkin (Cucurbita pepo var. styriaca). Methods: The animal manure and urea as pellet with four levels (150 Kg urea, 50 Kg urea + 3.5 ton animal manure, 100 (Kg) urea+ 1.5 ton animal manure and 150 (Kg) urea+1.5 ton animal manure) located in main plots and microelements with three levels (1000, 2000 and 3000 ppm) including a combination of iron, zinc, manganese and boron were located in subplots. Results showed that the highest number of female flowers, fruit yield, number of seeds per fruit, 1000 seed weight and seed yield was observed in using of 150 (Kg) urea + 1.5 ton manure pellet Increasing of nitrogen levels increased plant growth parameters, yield components and seed yield in pumpkin. Results: There was no significant difference between pelleted manures in seed oil percentage and seed protein but the highest oil yield was obtained in the treatment of 150 (kg) urea + 1.5 ton manure pellet which is related to higher seed yield in this treatment. The highest amounts of mentioned parameters are obtained in concentration of 2000 ppm of microelements except of seed protein which is observed in a concentration of 3000 ppm. At whole among of these fertilizer treatments, 1.5 ton animal manure + 150 (Kg) Urea as pellet with 2000 ppm of microelements is much recommended for maximum qualitative and quantitative properties in pumpkin.
