ANOVA - Opis:
- The quality of plants can be assessed according to the basic quantitative nutrient ratios. Moreover, proportions and relationships between macronutrients in plant biomass can be an indicator of the composition of plants and nutrient limitation. The research deals with the influence of soil amendment with mineral, organic and mineral-organic fertilisation on quantitative changes in nutrient ratios determined for camelina, white mustard and spring barley cultivated on light soils in subsequent years. A 3-year pot experiment was conducted with two doses equivalent to 70 kg N ha-1 (I) and to 170 kg N ha-1 (II). Plant material was subjected to chemical analyses in order to assess the macronutrient content, after which mutual proportions of individual nutrients were calculated based on the acquired data. Changes in ratio values were visualised using statistical tools, i.e. multivariate analysis of variance MANOVA and standard analysis of variance ANOVA. Regardless of the applied fertilisation, white mustard showed the highest values of most calculated nutrient ratios, although the values of nutrient ratios were consistent with those given in the literature as adequate only for spring barley. Generally, the fertilisers applied in a dose equivalent to 170 kg N ha-1 resulted in higher values of nutrient ratios, which was observed especially in the case of NPK. The study clearly demonstrated that the plant species diversity as well as fertilisation play a crucial role in quantitative changes of nutrient ratios. It is worth stressing that both organic fertiliser and mineral-organic fertiliser similarly affected nutrient ratio values.
