Effect of different soil fertilizing treatments on some of agro morphological traits and mucilage of Isabgol (Plantago ovata Forsk)

To evaluate the effects of soil fertilizing treatments on agro morphological traits and mucilage of Isabgol, a glasshouse experiment was conducted in College of Agronomy and Animal Sciences, University of Tehran. The experiment was conducted as a factorial based on complete randomized block design with three replications. In this study, the effects of soil fertilizing treatments including control, two level of chemical fertilizer (N and P), two level of cattle manure (dairy cow manure), two level of combined use of cattle manure and chemical fertilizer and Barvar Phosphate biofertilizer (BPB) inoculation were investigated. The results showed that fertilizing treatments revealed significantly higher yield, yield components, mucilage and mucilage yield than control. The effect of BPB on the majority of above mentioned traits were significant, while mucilage percentage was not affected by BPB. Cattle manure and combined use of cattle manure and chemical fertilizer were more effective than chemical fertilizer and significantly increased grain yield and mucilage. The highest grain yield (0.916 gr/plant) was obtained from N2oPio+20 ton/ha cattle manure with BPB inoculation. Keywords: Isabgol; Chemical fertilizer; Manure
