Description

The nitrogen fixation performance of some typical members of Greek pastures was examined under comparable conditions. The plants were grown on non-inoculated soil samples taken from 3 different regions of Greece. High N-fodng activity was detected in nodulated roots of Trifolium pratense and Medicago saliva but comparatively lower in Trifolium repens, T. hybridwn and Lotus comiculallls. Also, high activity was noted in the rhizosphere of the grasses Lolium perenne and Phalaris aquatica. The isolation of highly efficient N-fixing indigenous Rhizobium strains is reported.
