Effectiveness of potato cultivation using nanosized silica under conditions of Kamchatka krai

Аннотация

The results of trials of nanosized silica and its preparation forms under the conditions of Kamchatka krai are given. The dose and methods of silica usage for potato cultivation were identified. When introduced into the soil, silica improved productivity to 16.1–25.7% (2.8–3.6 t/ha). Treatment of tubers and plants with Miwa agro improved productivity to 12.4–16.9% (2.2–3.0 t/ha), with silica (gel) to 13.5–20.3% (2.4–3.6 t/ha) and silica (powder) to 10.7–16.4% (1.9–2.9 t/ha). We offer effective methods of using silica and Miwa agro to reduce the incidence of Rhizoctonia solani. Silica improves phosphorus-potassium nutrition of plants.
