Abstract
The responses of two pea genotypes to treatment with Rhizobium Nod factors were analysed in a pot experiment with a completely randomised design. The first-order factor was pea cultivar: Milwa and Klif, and the second-order factor was seed soaking: control (distilled water), solutioncontaining Nod factors (LCOs) at a concentration of 10 -12 M·dm -3 water. Pea plants were harvested at the flowering (BBCH 60) and at fully ripe stage (BBCH 90). In both pea cultivars, the application of Rhizobium Nod factors improved plant growth and yield. Nod factors (LCOs) accelerated seed germination and contributed to significant differences in seedling emergence patterns between days 7 and 11 after seed sowing. Nod factor treatment increased the number and weight of root nodules, thus stimulating the growth of vegetative and reproductive organs in pea plants. Nod factors had the greatest influence on the dry matter yield of peas at the fruit development stage, which is marked by intensive plant growth. The increase in seed yield observed after the application of Rhizobium LCOs resulted from a higher number of pods and seeds per plant and improved grain plumpness. It was found that the number of root nodules was highly correlated with seed yield. Several differences in the responses of the analysed genotypes to Nod treatment were observed, most significant being a higher number of root nodules and improved yield of peas cv. Klif.
