The efficiency of different methods of growing sweet potato (Ipomoea batаtas) planting material

Abstract

The purpose of the study was to determine the efficiency of different methods of obtaining sweet potato planting material (through potted seedlings or unrooted cuttings) in the conditions of the Left-Bank Forest-Steppe of Ukraine. Research methods: field, laboratory, calculation and statistical. The potting method facilitates the formation of more developed plants (with an increased number of shoots per plant and their total length). Slips as a method of obtaining planting material for sweet potatoes provides more intensive growth rates, the formation of tuber yields at the level of 14.8 t/ha with a high content of dry matter (13.8%), starch (10.7%) and vitamin C (5.33 mg/100 g). When using potted seedlings, some sweet potato bushes are found to have deformed tubers (3.5%), but the proportion of bushes that do not form tubers at all decreases (8.3% compared to 10.0% when using slips)
