Abstract
There is no information on the role of micronutrients on the mass production of the vesicular arbuscular mycorrhizal fungi. Hence zinc, copper and managanese at 4 different levels in Ruakura plant nutrient solution viz. 1/4, 1/2 and double the recommended level were studied to select the suitable level for mass production ofGlomus fasciculatum inoculum raised inChloris gayana (Rhodes grass) using perlite: soilrite mix (1:1 by volume). Percentage root colonization, extramatrical chlamydospore number and number of infective propagules per unit weight of the inoculum were maximum at half the recommended level i.e. 0·18, 0·04, 0·73 mM of Zn, Cu and Mn respectively.
