“…All nitrogenase indicators were significantly affected by the study year (Table 3) and the effects of Nod and Y × Nod interaction were significant for nitrogenase per 4.5 dm −3 of soil and 1 g of nodule dry weight. The beneficial effect of the Nod factors on nitrogenase activity in the relatively dry growing season 2012 (Table 5) was greater than in an earlier pot experiment with pea under near optimum water supply [12]. The increasing nodule activity in response to the Nod factors could be partially explained by symbiotic competitiveness of the bacterial strains [6].…”

Growth and symbiotic activity of legumes are mediated by Nod factors (LCO, lipo-chitooligosaccharides). To assess the effects of application of Nod factors on symbiotic activity and yield of pea, a two-year field experiment was conducted on a Haplic Luvisol developed from loess. Nod factors were isolated from Rhizobium leguminosarum bv. viciae strain GR09. Pea seeds were treated with the Nod factors (10−11 M) or water (control) before planting. Symbiotic activity was evaluated by measurements of nitrogenase activity (acetylene reduction assay), nodule number and mass, and top growth by shoot mass, leaf area, and seed and protein yield. Nod factors generally improved pea yield and nitrogenase activity in the relatively dry growing season 2012, but not in the wet growing season in 2013 due to different weather conditions.

“…The beneficial effects of NF application on roots, plant physiology, growth, and yields were observed under some stressful conditions such as low pH and temperature as well as water and salt stress (Duzan et al, 2004;Prudent et al, 2016;Nandhini et al, 2017). The positive effects of NF on pea growth and symbiotic activity were noted in compacted soils (Siczek et al, 2013). In field conditions, NF generally improved nitrogenase activity and pea yield in relatively dry but not during wet growing seasons (Siczek et al, 2014).…”

A b s t r a c t. Nod factors produced by rhizobia are one of the most important signals involved in symbiotic associations involving legumes. A field trial was performed to assess the symbiotic activity, rhizosphere biological parameters, and plant biomass of faba bean (Vicia faba L.) treated with Nod factors. The soil was a Haplic Luvisol derived from loess. The faba bean seeds (cv. Granit) were soaked with an Nod factors solution (260 nM) or water (control) and sown. At the flowering stage, the genetic diversity of rhizobia (based on PCR-RFLP profiles and the sequencing of the 16-23S rDNA and nodD gene), nitrogenase activity (acetylene reduction assay), and nodule biomass were evaluated. Nitrogen yield and plant biomass were determined at the flowering and maturity stages. Rhizosphere soil was examined during plant growth in relation to the activities of dehydrogenase, protease, urease, and acid phosphomonoesterase. The results indicated that the application of the Nod factors improved nitrogenase activity (by 74-80%, depending on the parameter analysed) and increased the genetic diversity of rhizobia inhabiting root nodules, plant nitrogen content (by 16.8%, at maturity), and seed protein yield (by 14.6%). The rhizobial population became more heterogeneous under the influence of the Nod factors than it was for the control (12 and 7 specific genotypes, respectively). At the flowering stage, Nod factors enhanced dehydrogenase, protease, and acid phosphomonoesterase activities by 46, 36 and 9%, respectively. The results revealed the positive effect of Nod factors at reducing water deficiency effects during a growing season with a short-term rainfall deficit.
