Effect of seaweed extract and phosphatebarvar-2 on the growth, yield and essential oil content of coriander (Coriandrum sativum)

The aim of this experiment was to investigate the effect of biofertilizers such as phosphatebarvar-2 and seaweed extract in increasing growth traits, quality and quantity of coriander.

This study was carried out as a field experiment in a factorial based on completely randomized design with four replications. in the west of Iran, in 2016-2017. The first factor was consisted of seaweed extract in three levels (no extract, one percent and two percent) and the second factor was including phosphatebarvar-2 in two levels (inoculation and no inoculation).

The results showed that the interaction between phosphatebarvar-2 and seaweed extract had a significant effect on plant height, seed essential oil content, and phosphorus concentration in aerial parts. The highest essential oil content (0.448%) was obtained in the level of % 2 seaweed extract and inoculation with phosphatebarvar-2 fertilizer. The highest (4.962 kg/ha) essential oil yield was obtained in the treatment of inoculation with phosphatebarvar-2 and 1% seaweed extract. Also the highest (3.583%) amount of phosphorus in aerial parts was obtained in the treatment of inoculation by phosphatebarvar-2 and %2 seaweed extract.

The use of phosphate biofertilizer along with seaweed extract can improve the growth traits and quality of essential oil in coriander.
