Abstract
In the complex of priority directions for development of potato production in the Russian Federation, the most urgent task is to increase efficiency of using varietal resources of the best domestic breeding achievements, as well as development of modern technological schemes for production of initial, original and elite seed potatoes. Recently, many attempts have been made to improve the technology of growing potato mini-tubers, which belong to the category of starting material in seed production, in order to obtain the maximum number of tubers per unit area. The main goal of the research was to study the effect of biological agents: Albit (poly-beta-hydroxybutyric acid + magnesium sulfate + potassium phosphoric acid + potassium nitrate + carbamide), BisolbiSan (Bacillus subtilis, strain H-13 + metabolites obtained during the cultivation of the strain), Prorastin (N, P2O5, K2O, Cu, Co, Zn, humic acids, auxins, gibberellins, cytokinins), Polystine (N, P2O5, K2O, Cu, Co, Zn, fulvic acids, auxins, gibberellins, cytokinins) and a product based on fungal arbuscular mycorrhiza (Rhizophagus irregularis) on yield of conditioned mini-tubers of potato cv. Ariel and cv. Sadon and their average weight by fractions in protected soil conditions. The one-factor experiment was carried out in a greenhouse of spring-summer type. Potato micro-plants were grown in 5L plastic pots filled with soil Agrobalt-C. Experiment variants: 1) Control (without treatment); 2) Albit, pre-treatment + two foliar dressings; 3) BisolbiSan, pre-treatment+3 foliar dressings; 4) Prorastin + Polystin, pre-treatment (Prorastin) + 2 foliar dressings (Polystin); 5) Product based on the fungal arbuscular mycorrhiza (Rhizophagus irregularis), pre-treatment of micro-plants. It was found that Prorastin and Polystin and treatment of the root system of micro-plants before planting with bioagent based on the fungal arbuscular mycorrhiza (Rhizophagus irregularis) provided the best indicators for yield of conditioned mini-tubers cv. Ariel and average weight of tubers of both cultivars.
