Abstract
Crop yields can be significantly increased by using pectic polysaccharides – natural ecologically safe and effective plant growth stimulants. In this paper, high growth-stimulating activity of pectins with respect to potatoes is shown. The research was conducted in 2012–2015 in the Komi Republic (Syktyvkar) on sod-podzolic soils with an average humus content of 2.8–3.4%. The objects of the study in the field experiments were zoned potato varieties: early-ripening Gloria variety and the middle-aged variety Nevsky. The following pectic polysaccharides served as stimulants of potato growth and development: heracleuman – pectin of Heracleum sosnowskyi Manden., lemnan – pectin duckweed Lemna minor L. and silenan – pectin of callus tissue of campion Silene vulgaris (M.) G. Processing of potatoes with aqueous solutions of pectic polysaccharides included pre-planting soaking of potato tubers in water and spraying potato plants in the phases of 3–5 leaves and tuber formation. For processing potatoes, working solutions were used, which were prepared from 100 times diluted 0.002% aqueous solutions of pectins. The consumption of the working solutions of pectins were 10 liters on 1 ton of tubers and 300 l/ha of planting potatoes. Tubers and potato plants treated with water instead of pectins were used as control samples. It is established that all tested pectins possess growth-stimulating activity and processing of potatoes with aqueous solutions of pectic polysaccharides increases the early and overall yield of this crop, as well as the content of dry matter, starch and vitamin C in potato tubers.
