“…The use of a complex of microbial products proved to be effective, which ensured an increase in the content of exchangeable potassium in the soil by 11.5-40.6% compared to the control. That is, microbial preparations with phosphorus and potassium mobilising agents have the prospect of being used in technological schemes for growing vegetable plants, which is confirmed by the research of S. Shanmugam et al (2022). The use of fertilisers improved the development of white cabbage plants, especially under organic-mineral fertilisation systems (Table 2).…”

The research relevance is determined by the need to study the long-term use of various fertilisers and their effect on the soil nutrient regime, yield, and quality of white cabbage. The research aims to determine the effect of different nutrition optimisation systems on the yield and quality of late-ripening white cabbage in irrigated vegetable-fodder crop rotation. Field, statistical, calculation-analytical and laboratory methods were used to conduct the research. It was established that the use of a mineral fertilizer system (N550P260K370 + “NutriVant Plus Universal”) led to an increase in the level of supply of the topsoil with mobile nitrogen, phosphorus, and potassium compounds, and had a positive effect on the biometric parameters and productivity of white cabbage plants. All fertilisation systems, except for the application of microbial preparations only provided a significant increase in yields in the range of 21.6-71.8%. However, a significant increase in the content of vitamin C in cabbage heads was observed for all fertilisation systems studied, except for the use of 40-60 t/ha of manure + N60P60K45 та N550P260K370 + “NutriVant Plus Universal”. The nitrate content in the heads did not increase significantly after fertilisation. The ineffectiveness of using the system of microbial preparations, including seed treatment with Azotobacter chroococcum, and soil treatment before pre-sowing cultivation with Roundfix, to optimise the nutrition of white cabbage plants was noted. (Paenibacillus polymyxa, Bacillus megaterium var. phosphaticum, Enterobacter, Azotobacter chroococcum, Bacillus subtilis) and five foliar fertilisers Organic Balance (Bacillus subtilis, Azotobacter chroococcum, Paenibacillus polymyxa). The practical value is determined by obtaining results for adjusting fertiliser doses when planning their application in crop rotations of farms of different forms of ownership

Purpose Beetroot is a model crop for studying root competition in intercropping systems because its red-coloured roots facilitate non-destructive visual discrimination with other root systems of intercropped plants. However, beetroot also has white roots, which could alter how root competition is interpreted. Here we investigated the quantity of white versus red roots in beetroot to quantify the effect of this phenomenon. Methods Beetroot was mono-cropped or inter-cropped with white cabbage in a field trial. The distribution of beetroot roots was recorded to 2.5 m soil depth on three dates following the minirhizotron method. Roots in each 0.5 m soil layer were counted and categorised into groups based on colour (white roots, coloured roots, and white roots traced back to be coloured) to investigate the influence of white roots on accuracy of root registration. A pot experiment was conducted with three cultivars to verify if white roots are a general characteristic of beetroot. Results White roots in mono-cropped beetroot represented 2.5–4.8% of total roots, on average, across the rooted soil profile. However, white roots represented 6.9% and 11.6% of total roots in the deepest soil layer during August and October, respectively. White roots caused mono-cropped beetroot roots to be underestimated by 1–22% based on root colour discrimination. However, tracing white roots backwards and forwards to coloured parts of roots reduced underestimates to 0.5–15%. Intercropping did not influence the traceability of white roots compared to monocropping. The highest occurrence of white roots appeared during the early growth period and in the deepest soil layers, indicating a linkage to younger roots or higher root proliferation rates. Conclusion Beetroot represents a model crop for visual studies linking eco-physiology and root proliferation. The white roots of beetroot must be incorporated by studies of root competition in intercropping systems that use colour as a criterion.
