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

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