Abstract: | A pot experiment was conducted to evaluate the effect of indigenous arbuscular mycorrhizal fungi (AMF) and the synergy of indigenous AMF and sheep manure (SM) on potassium (K), calcium (Ca) and some micronutrient concentrations in cotton plant. Indigenous AMF were a mixture of Glomus viscosum, Glomus mosseae and Glomus intraradices initially isolated from a cotton field. Cotton was grown for 12 weeks and the elements of shoot were determined at three stages of plant growth. Inoculated cotton plants with AMF had higher concentrations of K, Ca, manganese (Mn), iron (Fe), copper (Cu) and zinc (Zn) than non-mycorrhizal plants. Shoot concentrations of these elements increased significantly when SM was added to mycorrhizal plants. Maximum plant micronutrient uptake was found in the treatment of AMF inoculation with SM. Mn, Fe, Cu and Zn uptake increased significantly by 457%, 282%, 272% and 295%, respectively, over control. Indigenous AMF combined with SM resulted in better plant growth and micronutrient uptake. |
