Abstract
The results of a two-year cycle of studying the vitality structure of the agrophytocenosis of winter rape intensive high-yielding hybrid Absolute under different fertilization systems, which provided different options in terms of background mineral nutrition, the use of growth-regulating drugs and different options for foliar feeding, are presented. The morphological parameters of winter rape plants were studied with the formation of four main blocks of indicators (root, stem, assimilation surface, generative part) and the initial data set was formed, which allowed to determine such indicators of agrocenosis vitality as the vitality coefficient, the module of morphological variability, the modified index of morphological integration, the quality index, the index of agrophytocenosis prosperity, the index of dimensional plasticity. The analysis of the determined parameters of vitality in statistical integration with the calculation of the range and mean value, variation and share of each factor according to the experimental scheme in the context of a multivariate analysis of variance scheme allowed to identify the factor components of influence on the vitality of winter rape agrocenosis, taking into account the variant of background fertilization, the use of growth regulation and foliar fertilization system in order to find the optimal variant of combined fertilization of winter rape. The increase in the optimization of winter rape vital structure in comparison with the control variant was estimated, with an additional increase in the indicators for a single graded increase in fertilization intensity. Conclusions were made about the optimal morphostructure of winter rape agrocenosis in variants of maximum intensification of mineral fertilizers application. At the same time, the maximum indicators of vitality assessment of winter rape agrocenosis in the variant of combining complex background fertilization with the use of various forms of fertilizers in combination with sulfur application against the background of growth-regulating drugs and complex application of multiple foliar fertilization were established, which provided the following parameters of plant vitality tactics: vitality coefficient (IVC) 1,312, module of morphological variability (Modx) 0.98–1.00, modified index of morphological integration (Immi) 0,711–1,335, quality index (Q) 43.00, index of agrophytocenosis prosperity (IQ) 3,07, index of dimensional plasticity (ISP) 1,427.
