EFFECTS OF RHIZOBIUM AND NITROGEN FERTILIZER ON NITROGEN FIXATION AND GROWTH OF FIELD PEAS

Abstract

Nitrogenase activities of single and multistrains of Rhizobium during the growing season were low and the inoculation treatments failed to increase yields or nitrogen contents of Century field peas. Nitrogen fertilization at seeding severely depressed nitrogenase activity but markedly increased forage and seed yields as well as protein contents.
