Effects of fertilizer treatments on yield quantity and quality of coriander
To investigate the effects of mycorrhizal fungi، phosphatic biofertilizer and manure application on yield and quantitative and qualitative criteria of coriander an experiment was conducted at Khoramabad during growing season of 2013. The experiment design was applied as factorial layout based on a randomized complete block design with 18 treatments and three replications. The factors were mycorrhizal inoculation in two levels (non-inoculation and inoculation)، phosphate biofertilizer in three levels (zero، 35 and 70 kg/ha) and manure in three levels (10، 20 and 30 ton/ha). Result indicated that mycorrhizal inoculation and phosphate biofertilizer had significant (one percent) effects on plant height، inflorescence number per plant، 1000 seed weight، seed yield، biomass yield، essential oil and essential oil yield of coriander. Mean comparison showed that the highest effects among factors were obtained by mycorrhizal inoculation on all parameters. The highest seed yield)1780. 67 kg/ha)، biomass yield (3831. 7 kg/ha) and essential oils (0. 4 percent) were obtained of inoculation with mycorrhiza، consumption of 70 kg/ha phosphate biofertilizer and 20 ton/ha manure and they were 80، 51 and 135 percent more efficient than chemical control، respectively. Positive and synergistic interactions were obtained between mycorrhizal inoculation × phosphate biofertilizer on seed yield.
