The influence of intensification agents on the yield of seed fraction in Siberian potato varieties

The article presents the results of evaluating the effectiveness of using various intensification agents (mineral fertilizer N40P40K80, chemical insecticide-fungicide seed dressing, as well as preparations based on humates Beres-8 and Relikt) in the propagation of the source material of the Siberian potato varieties Yuna, Lina, Zlatka in the forest-steppe conditions of the Novosibirsk Priobye. The purpose of the research was to determine the optimal combinations of seed dressings, humic preparations and mineral fertilizers to increase the productivity and yield of the mass and number of seed fraction tubers. The optimal ratio of the mass and quantity of seed tubers in the Yuna variety (weight percentage 75.6, multiplication factor 7.0) was obtained by treating the planting material with Celeste Top (0.4 l/t) in combination with Beres-8 (0.2 l/t) with subsequent spraying of the plantings with Beres-8 (0.2 l/ha) during the budding period without mineral fertilizers. For the Lina variety, the combination of these indicators was the best (weight percentage 71.6, multiplication factor 10.2) when treating planting tubers with Celeste Top (0.2 l/t) in a mixture with Relikt (0.01 l/t) followed by spraying the plants with Relikt (0.2 l/ha) without applying mineral fertilizers. For the Zlatka variety, the ratio of the mass and quantity of seed tubers was optimal (weight percentage 77.9, multiplication factor 10.8) when treating the seed material with Celeste Top (0.2 l/t) in combination with Beres-8 (0.2 /t) and spraying the crop plantings with Beres-8 (0.2 l/ha) with the addition of mineral fertilizers. The obtained results confirmed the high efficiency of the integrated use of chemical and biostimulating preparations in increasing the yield and seed productivity of potatoes, which can be recommended for original and elite seed production in Siberian conditions.
