Study of vesicular arbuscular mycorrhizal status of different types of plantation and the effect of indigenous vam on the growth of Sorghum bicolor
Plants grown in Casuarina equisitifolia field mycorrhizal soil was proved more efficient in promoting plant height, leaf number as well as leaf area index and highest VAM infection potential, which could provide more VAM infectionpotentiality in the early age of seedling establishment. In this treatment VAM infection percentage was found correlated with plant growth. All the observation suggested that higher mycorrhizal soil inoculum helped to produce plant growth in early stage which continued to be same at latter stage of plant growth also. Soil inoculums of Grassesalso proved as efficient as Casuarina equisetifolia soil inoculums for the growth of the plant height, dry weight in relation to highest VAM infection % and low VAM spore inoculum in rhizospheric soils.
