摘要: Abstract Studies were conducted in 2008 and 2009 to determine the effect of S-metolachlor rate application time on sweetpotato cultivar injury storage root shape under conditions excessive moisture at application. 1.1, 2.2, or 3.4 kg ai ha−1 was applied immediately after transplanting 2 wk (WATP) ‘Beauregard’, ‘Covington’, ‘DM02-180’, ‘Hatteras’, ‘Murasaki-29’ sweetpotato. One three d plots received 1.9 cm rainfall irrigation. resulted increased stunting 4 12 WATP, decreased no. 1 marketable yields, length width ratio compared with nontreated check. Sweetpotato stunting, treatments receiving 2 WATP similar In 2008, Covington Hattaras greate...
