Effect of phosphate solubilizing bacteria and mycorrhizal fungi on quantity and quality features of sweet William (Dianthus barbatus)

In order to study the effect of phosphorous solubilizing bacteria (P) and mycorrhizal fungi on quantitative and qualitative traits of sweet william (Dianthus barbatus), a factorial experiment carried out based on completely randomized block design with 12 treatments: mycorrhizal fungi in two levels (with and without), solubilizing phosphorous (P) bacteria in two levels (with and without) and super phosphate in three levels (0, 50, 100%) and 4 replications, 48 plots and 240 plants. Pseudomonas fluoresens and Claroideoglumus etunicatum, Rhizophgus intraradices and Funneliformis mossea were used for seed inoculation at sowing date. In this experiment, display life, chlorophyll content, colonization percent, phosphorus concentration and main stem height were measured. Results showed that effect of solubilizing P bacteria was significant on main stem height, display life, phosphorus uptake. Solubilizing phosphorus bacteriaÇmycorrhizal fungiÇ50% super phosphate treatment was the best treatment in colonization. Root colonization reduced significantly with increasing the chemical fertilizer application. The highest shoot dry matter observed in mycorrhizal fungi and 100% chemical fertilizer treatment. Solubilizing phosphorous bacteria increased vase life (66.00 days) compared to control treatment (32.75 days).
