Analysis of some quality indicators for wheat grown under biological conditions

Abstract On soil type calcic chernozem, in the period 2018-2022. an experiment with common winter wheat (Triticum aestivum L.) variety "Venka 1" was carried out. The experiment was set up in 4 replications in a randomized block design. The size of the experimental plot is 10 m-2. In October, the sowing was carried out after the predecessor sugar beet (Beta vulgaris L.), with 500 germinating seeds/m-2. Treatments in 4 variants are applied in the appropriate periods according to Maria Thun's calendar. The first variant is an untreated Control; the second was treated only with biodynamic preparations: VD (biodynamic preparation) 500 + VD 501 + Fladen preparation; The third option is treated only with biological preparations: Free N + Heliosulfur, and the treatment in the fourth option is a combination of the above two options: VD (biodynamic preparation) 500 + VD 501 + Flaten preparation + Free N + Heliosulfur. Growth phases indicated are according to the Zadoks scale. Data were processed using SPSS using the method of variance statistics. Student's criterion was used for assessment. It was found that wheat treated variants performed better in terms of some biochemical parameters.
