Abstract

 In order to evaluate the response of quantitative and qualitative characteristics of the ISABGOL (Plantago ovata Frosk.) medicinal plant to separate and combined a application of urea and biofertilizer an experiment was conducted in randomized complete blocks design at the Research Farm of Shahrekord University in 2011. The experimental treatments consisted of control (non-urea and BIOLOGICAL FERTILIZERs), U: 88 kg urea/ha, Az: Azotobacter, My+Az: Mycorrhiza + Azotobacter, Az+50% U: Azotobacter + 44 kg urea/ha, My + U: Mycorrhiza + 88 kg urea/ha, My + Az +50% U: Mycorrhiza + Azotobacter + 44 kg urea/ha. The results indicated that the SEED YIELD under separate application of Azotobacter was less than separate application of urea; however the MUCILAGE yield was similar to urea. The combination of Azotobacter with urea and/or Mycorrhiza did not change in seed and MUCILAGE yield in compared to urea. The maximum of seed and MUCILAGE yield (931 and 166 kg/ha, respectively) were recorded with using Mycorrhiza + 88 kg urea/ha. However, amended fertilizer had no significant effect on swelling factor and the percentage of ISABGOL MUCILAGE. In conclusion, the combined use of Mycorrhiza in oculant and urea leads to increase (54%) in yield, which can be verified potential of Mycorrhiza application for ISABGOL production under field conditions.
