Effects of Mycorrhiza, Phosphatic Biofertilizer on Photosynthetic Pigments and Yield in Coriander (Coriandrum Sativum L.)

In order 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 (Lorestan) during the growing season of 2013. The experiment des was conducted as factorial based on a randomized complete blocks design with 18 treatments and three replications. The factors were mycorrhizal inoculation in two levels, phosphatic biofertilizer and manure in three levels. The highest concentration of P in seed (3.67 %), leaf total carotenoid (2.39 µg ml-1) Biomass yield (3931.7 kg ha-1), seed yield )1780.67 kg ha-1) and harvest index (36.08%) was obtained in inoculation with Mycorrhiza, consumption of 70 kg ha-1 phosphate biofertilizer and 20 ton ha-1manure and they accounted for 51,168, 80 and 27 percent more than chemical control. Positive and synergistic interactions were obtained between Mycorrhizal inoculation × phosphate biofertilizer on leaf total carotenoid, seed yield and harvest index. According to the results of this research, inoculation with mycorrhizal produced the maximum grain yield, biological yield and harvest index compared to phosphate biofertilizer and manure.
