Influence of Tytanit® and EM on biochemical, physiological, and qualitative parameters of common bean

The role of preparations supporting plant growth is mainly to reduce the harmful effects various stress factors on plants and ensure high yields good quality. This experiment compared effect mineral stimulator Tytanit® biological preparation Effective Microorganisms (EM) physiological biochemical activity, as well yield common bean (Phaseolus vulgaris L.). photosynthetic pigments, free proline malondialdehyde were assayed at three phenological phases bean: 15 BBCH, 24 65 BBCH. parameters included average number pods per plant, their fresh dry mass. Additionally, nutrient content in was determined according atomic absorption spectrometry method. study revealed a positive both increasing chlorophyll a, b, carotenoids leaves. Plants treated with characterised by highest proline, while EM maintained aldehyde similar level untreated significantly reduced content. Both decreased Mn, Mg, P, Ca did not have substantial impact yield.
