Requirement of Arbuscular Mycorrhizal (Glomus mosseae) Inoculum for Optimum Growth of Tree Seedlings in Lateritic Soil

Application of Arbuscular mycorrhizae, as preinoculation in nurseries, is an effective tool for afforestation in dry regions. Three vastly used test crops-including Acacia auriculiformis, Leucaena leucocephala and Delonix regia were selected to standardise the doses on inoculums. Growth parameters were found enhanced over control at 180^th day accordingly with the quantity of inoculum, but increment from 15 to 25 g inocula treatment was not significantly varied. Hence, 15g or 20g may be taken as standard for this soil type.
