INFLUENCE OF MICROBIOLOGICAL PARAMETERS ON VEGETATIVE PLANT DEVELOPMENT AND YIELDS OF PERSPECTIVE VARIETIES OF SWEET-BERRY HONEYSUCKLE

Abstract

The aim of the research is to study the effect of microbiological nitrogen and phosphorus agrochemicals on the general condition of plants and the yield of blue honeysuckle on sod-podzolic soils in the conditions of the Republic of Mari El. The experiment was conducted according to the following scheme - factor A – grade: Blue spindle (control), Tatiana (No. 50), Memory of Silaev, Nizhny Novgorod dessert, Charmer (No. 81), Gift to Dergunov, Dainty; factor B – fertilizers: control – without fertilizing, bacterial fertilizers Azotovite, Phosphatovite, Azotovite + Phosphatophyte, consumption rate in each variant – 14 l/ha, water – 3000 l/ha, ammophoska (N₁₂, P₁₅, K₁₅), application dose – 300 kg /ha. The repetition of the experiment is threefold, the placement of plots is rendominized, the term for applying microbiological and mineral fertilizers is the first decade of May, once. The application is superficial. The use of bacterial agrochemicals Azotovite and Phosphatovite in the initial period of growth of honeysuckle plants has a positive effect on their further development and general condition, as well as contributes to an increase in potential yield. The largest average annual increase, which was 2.1 times higher than the control (Blue spindle on a non-windy background), was obtained in the variant of the combined use of bacterial nitrogen and phosphorus agrochemicals in the Charming variety (36 cm). The joint application of Azotovite and Phosphatovite: as an early spring top dressing, allows you to significantly increase the yield of blue honeysuckle berries (the increase was + 0.4 t/ha with a yield of 2.0 t/ha).
