Effect of Bacillus megaterium var. phosphaticum Bacteria and L-Alpha Proline Amino Acid on Iron Content in Soil and Triticum aestivum L. Plants in Sustainable Agriculture System

Research was conducted in Poland 2017–2019 at Siedlce University of Natural Sciences and Humanities Siedlce. It aimed determining the effect bacteria Bacillus megaterium var. phosphaticum, amino acid L-alpha proline, mineral nitrogen fertiliser regime on iron content soil during period rapid growth spring wheat plants, as well grain straw. The following two factors were examined: (I) biological products: untreated control, phosphaticum + proline; (II) regime: nonfertilised 60 kg N·ha−1, 90 N·ha−1 foliar fertilisation. study demonstrated that, plant growth, Fe highest an application proline applied rate N·ha−1. This combination resulted concentration uptake by grain, whereas for straw, same result also achieved a
