The Effects of Different Mycorrhiza Species, Compost and Rock Phosphate Applications on the Growth of Sorghum Plant

Abstract

The aim of this study was to determine the effects of different compost and rock phosphate dosesapplications with different mycorrhizal species inoculation on sorghum plant growth and nutrientuptake. Dosages 0, 20, 40 gr compost kg-1soil as were used as compost, and 0, 2, 4 gr rock phosphate/soilas rock phosphate sources. Funnelformis mosseae, F. caledonius, Claroideoglomus etunicatum,Rhizophagus clarus, indigenous and cocktail (mixture) mycorrhizae were used. Shoot and root drymatter, P and Zn concentration and root percentages of mycorrhizal infection were determined.According to the research findings, mycorrhiza inoculation significantly increased the shoot and rootdry matter, P, Zn and root infection of sorghum plant more than rock phosphate and compostapplications. F. caledonius was determined as the most effective species. While 20 and 40 g compostkg-1soil doses applications were most effective, it was concluded that the shortage of cultivation timeresulted that the rock phosphate may not be sufficiently dissolved for nutrient supply to plant growth.
