To study the effects of different soil fertilizing treatments on yield, yield component and seed mineral nutrients content in Isabgol, a glasshouse experiment was conducted in College of Agronomy and Animal Sciences, University of Tehran. In this research effect of chemical fertilizers containing N and P in three levels (chemical fertilizing treatments), cattle manure in four levels (organic fertilizing treatments), and mixture of chemical fertilizer and cattle manure in four levels (integrated fertilizing treatments) were investigated in a complete randomized block design with three replications. The results showed that fertilizing treatments had significant effect (p¡Ü 0.05) on all measured traits. Seed and mucilage yields increased with increment in rate of fertilizers applied; so the highest seed and mucilage yields were obtained by N20P10+20 ton/ha cattle manure. Mucilage percentage, seed and mucilage swelling factor were significantly higher (p¡Ü 0.05) in organic and integrated fertilizing treatments than chemical treatments and control. The results also showed that seeds N, P and K contents were positively affected by all soil fertilizing treatments.
