Mycorrhizal fungi are associated in mutualistic symbiosis relationships with fine roots of the plants. These fungi help in enhancing plant health to combat both biotic and abiotic stresses. The present investigation was undertaken to study the effects of arbuscular mycorrhizal fungi (AMF) on the growth performance of pea (Pisum sativum). Soils were...
