Ефективність різних способів вирощування посадкового матеріалу батата (Ipomoеa BatаtaS)

Abstract

The purpose of the study was to establish the effectiveness of different methods of obtaining sweet potato planting material (through potted seedlings or unrooted cuttings) in the Left-Bank Forest-Steppe of Ukraine. Research methods: field, laboratory, statistical.The use of pottedseedlings method as a method of obtaining sweet potato planting material provides the formation of more developed plants of the culture (with an increased number of shoots per plant and their total length).The use of slips as a method of obtaining sweet potato planting material provides more intensive growth rates, the formation of tuber yields at 14.8 t / ha with a high content of dry matter (13.8 %), starch (10.7 %) and vitamin C 5.33 mg / 100 g).Using potted sweet potato seedlings occur with deformed tubers (3.5 %), but decreases the proportion of shrubs that do not form the tubers (8.3 % compared to 10.0 % for the use of the slips).
