    Combined Effect of Extract Containing Rhizobial Nod Factors and Mineral Fertilization on Growth and Yield of Barley and Triticale
    (MDPI, 2026) Wielbo, Jerzy; Podleśny, Janusz; Podleśna, Anna; Kidaj, Dominika; Sroka-Bartnicka, Anna; Klikocka, Hanna
    The development of new methods enhancing the growth and yield of cereals is still needed in crop production due to their great importance in human diet and as livestock fodder. In our study, new fertilizer-biostimulators with micro- and macroelements and extract containing lipochitooligosaccharides (LCOs) produced by Rhizobium leguminosarum bv. trifolii were used for stimulation of growth of barley and triticale in greenhouse conditions. The preparations were applied at the tillering and shooting stages, whereas plant traits were studied at flowering and at full maturity. The best results were recorded after the joint treatment of the plants with LCOs and mineral fertilization. The application of such a mixture significantly increased the length and mass of roots at flowering in both studied species. A beneficial effect of the treatment was also observed in barley and triticale yields. At full maturity, the grain mass per plant was significantly enhanced, which was the effect of an increased number of grains per ear and increased mass of 1000 grains.

    The Influence of Foliar Application of Nod Factors (LCOs) and Microelements on the Growth, Development, and Yield of Peas (Pisum sativum L.)
    (MDPI, 2025) Podleśny, Janusz; Wielbo, Jerzy; Podleśna, Anna; Klikocka, Hanna; Kidaj, Dominika
    Peas are a popular crop grown in Poland, but their yields are variable and often low; therefore, new cultivation methods are constantly being sought. In this paper, we present the results of a three-year greenhouse study examining the effect of preparations containing rhizobial Nod factors and/or selected microelements (B, Cu, Fe, Mn, Zn, and Mo) on the physiological parameters, growth, and yield of peas. Pea plants were tested at the flowering stage (BBCH 60), at the green ripe stage (BBCH 75), and at the fully ripe stage (BBCH 90). Leaf area, SPAD, gas exchange parameters, and chlorophyll fluorescence were measured, and the number and mass of root nodules, as well as seed yield and yield components, were determined. The treatment was most effective when Nod factors were used in combination with microelements. The increase in pea yield induced by the application of both components can be attributed to the higher number of pods and seeds per plant because no significant variations were noted in the number of seeds per pod and 1000 seed weight. The number and weight of nodules were significantly correlated with the pea yield, and the value of the correlation coefficients was influenced by the application of both components.
