Effect of Vasicular-Arbuscular Mycorrhiza (VAM) and PGPR on plant growth response of two cultivars of Chenopodium quinoa Willd (INIA – 427, INIA- 431) in both field and pot experiments

Abstract

Experiments were conducted to approach the effect of interaction of Glomus mosseae, Glomus aggregatum (VAM) and Pseudomonas aeruginosa (PGPR) on the growth, percentage of mycorrhizal infection and plant growth parameters of Chenopodium quinoa Willd. Which belongs to Chenopodiacea family considered as a healthy food because of its good source of many nutrients, which when consumed with other foods can be an important part of a balanced diet. Quinoa is most known for its protein content compared to other plant foods. The present research work conducted at Telangana University, Nizamabad, Telangana state from November 2016 to March 2017. The research work carried by two cultivars of Chenopodium quinoa Willd. The two cultivars has shown highest yield and significant increase in N, P, K levels, plant dry weight, fresh weight and in total plant biomass and also estimated that the difference between grains yield per plant, protein content of the grains, weight of 100 grains over the control was recorded when the experimental plants were subjected to VAM or PGPR alone or in combination. VAM propogules were established successfully in sterile soils and the effectiveness of PGPR inoculants were appreciably increased in association with VAM. Especially dual infection of VAM and PGPR expressed a higher beneficial effect on root and shoot development, percentage of mycorrhizal infection and plant growth parameters than either inoculum alone.
