The Effect of a Preparation Containing Rhizobial Nod Factors on Pea Morphological Traits and Physiology
The aim of the study was to determine the possibility of increasing the pea yields by improving the symbiotic nitrogen fixation through the use of a preparation containing bacterial Nod factors (NFs). Two pea cultivars were included in the experiment: Wiato (with traditional foliage) and Model (afil...
