Evaluation of AMF formulations on growth, root colonization and biophysical parameters of maize (Zea mays L.)

Abstract

Mycorrhizal formulations are becoming increasingly popular in many countries and for many crops, but less studies on their effect on plant parameter and mycorrhizal studies. There for we have evaluated different AMF formulations under green house studies. In this study soil samples from the UAS, Dharwad experimental plots were collected, sterilized and used in a pot experiment. The maize Hybrid (GPMH-1101) was grown in the pots upto 45 days. The plant dry weight, root length, bio physical parameters, P concentrations in plant tissues was measured and the extent of root colonization by arbuscular mycorrhizal fungi (AMF) was determined. AMF formulations have shown significant influence on the growth and biophysical parameters of plants that could be related to differences in the infective propagules in formulations. The inoculum potential and efficacy of the AMF formulations can promote P uptake and benefit plant growth.
