EFFECTIVENESS OF PRECISION AGRICULTURE ELEMENTS IN POTATO PRODUCTION IN THE WESTERN SIBERIAN FOREST-STEPPE

Abstract

Theresultsofcomprehensiveresearchconductedin 2020-2022 usinggeoinformationtechnologies in potato cultivation at ZAO Plemzavod "Irmens" in the Ordynsky District of the Novosibirsk Region, located in the forest-steppe zone of Western Siberia, are presented. Potatoes require specific environmental factors to achieve high yields with good product quality. Using satellite navigation systems ensures an increase in potato yield and product quality. The research aims to develop elements of potato cultivation technology using innovative satellite navigation systems. The experiments were conducted in the soil and climate zone of drained forest-steppe in the northern forest-steppe area of the Priobye foothills. The soil of the experimental plots is alkaline black soil with a humus content of 6.32%, total nitrogen content of 0.28%, phosphorus content of 0.23%, and potassium content of 1.19%. The concentration of quickly hydrolysable nitrogen was 10.3, exchangeable phosphorus was 20.7, and exchangeable potassium was 14.4 mg/100 g of soil, with a pH of Early potato varieties Gala and Riviera were cultivated in the experiments. During the research period, aggregated data were obtained, and regression equations between yield indicators, the sum of productive soil moisture reserves, and precipitation in interphase periods of potato varieties were calculated. Correlation coefficients were determined for specific interphase periods. The dependence of potato yield on precipitation indicators in interphase periods was established. The significance of precision agriculture elements in ensuring early potato varieties' high product and quality was noted.
