Abstract
The competitiveness of 10 sorghum [ Sorghum bicolor (L.) Moench] hybrids to weeds and their tolerances to commonly used sorghum herbicides were studied across Nebraska. The three best weed competitors in this study were sorghum hybrids ‘RS 671′, ‘RS 690′, and ‘AKS 663′; whereas the three poorest weed competitors were ‘AKS 614′, ‘NB 505′, and ‘RS 633′. Sorghum hybrids showing a significant yield reduction from a 2× rate of 2-chloro-4-(ethylamino)-6-(isopropylamino)- s -triazine (atrazine) were ‘SD 441′, ‘SD 451′, and ‘NB 505′. ‘SD 441 also suffered a significant yield reduction from a normal rate of 2-chloro- N -isopropylacetanilide (propachlor) applied preemergence plus a 4× rate of (2,4-dichlorophenoxy)acetic acid (2,4-D) applied postemergence. With the above exceptions, sorghum hybrids generally showed considerable tolerance to 2× rates of herbicides commonly used on sorghum.
