Effect of Vesicular Arbuscular Mycorridzae on the Growth and Mineral Nutrition of Teak (Tectona grandis Linn. F.)

The effect ofVAM Fungi (Glomus fasciculatum and Glomus mosseae) on initial establishment and mineral nurition of Teak was studied. The uptake of various macro-nutrients, (N,P, K) and micronutrients (Cu, Zn, Fe, Mn) studied along with various growth parameters. G. mosseae + G. fasciculatum treated plants which registered greater growth, also showed an increase in the concentrations of Phosphate, K and Mn, while N, Cu, Zn, Fe concentrations decreased in the shoots. The plants to which G. fasciculatum in combination with a small amount of rock phosphate was given was the next best treatment followed by G. fascicualatum alone treated plants. G. mosseae + G. fasciculatum + Phosphate treatment proved to be deleterious to the growth of the teak plants. The possible role of V AM on the growth of Teak is discussed keeping in view the specificity of host-symbiont relationship.
