Growth, yield, and quality of sweet potato varieties for vegetables in Thua Thien Hue province

Abstract

The study was carried out on seven sweet potato varieties to identify the ones with good growth and resistance and high yield and quality. The experiments were designed in a randomized complete block design with three replicates in the 2019 Summer–Autumn crop at the Centre for Agricultural Research And Services of the Faculty of Agronomy, University of Agriculture and Forestry, Hue University. The varieties’ characteristics were determined according to the National Technical Regulation on Testing for Value of Cultivation and Use of sweet potato varieties, issued by the Ministry of Agriculture and Rural development. The results indicate that three of the seven varieties have good growth, pest and unfavourable condition resistance, high yield (9,7–12,0 tons/ha), trade item ratio (≥50%), and quality. These varieties were suggested to test on a large scale at the research locality.
