Hochhalter Abstract High-residue farming and crop diversification practices are replacing conventional tillage and crop-fallow in the Great Plains. Our objective was to determine if cultivar ranking changed when six barley (Hordeum vulgare L.) cultivars were grown following canola (Brassica napus L.), corn (Zea mays L.), pea (Pisum sativum L. subsp. sativum), and spring wheat (Triticum aestivum L. emend. Thell.) from 2010 through 2013 in southwestern North Dakota. An interaction between the previous crop and barley cultivar was detected in 2011 and 2013 for grain yield (P < 0.10). However, one cultivar in 2011 and three cultivars in 2013 produced equal or greater yields than those produced by other cultivars, regardless of previous crop. Grain yield was comparable with or greater following field pea to that following other crops in 2010 and 2012 when a previous crop cultivar interaction did not exist. Interactions between the previous crop and barley cultivar occurred in only 2 of 12 instances for grain quality traits, and even then at least one cultivar was among the top performers consistently after each previous crop treatment. These results suggest that the previous crop is not an important consideration when making barley cultivar recommendations.","PeriodicalId":100342,"journal":{"name":"Crop Management","volume":"13 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2134/CM-2014-0056-RS","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71932488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This represents the time when fall-planted cover crops would likely be seeded in Minnesota. Earliness to anthesis is important in organic production systems where timing of rye management is affected by rye growth stage. The relationships among growing degree days (GDD), growth stage, and aboveground biomass were evaluated to predict how these factors influence anthesis date and how late in the fall rye could be planted without delaying anthesis. The study occurred in 2006 and 2007, which happened to have abnormally warm and cool growing seasons, with the earliest anthesis dates in 2007 being 25 May, 28 May, and 5 June at St. Paul, Lamberton, and Roseau, respectively, and dates in 2008 of 10 June, 11 June, and 17 June. Our results indicate that there was no fall biomass requirement but also that it was critical to accumulate at least 309 GDD in the fall so as not to delay spring anthesis. This information enables growers to choose appropriate planting dates for rye that will not delay anthesis. The optimal planting date corresponded to planting by late September (~20) in southern and early September (~8) in northern Minnesota.","PeriodicalId":100342,"journal":{"name":"Crop Management","volume":"13 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2134/CM-2013-0096-RS","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71951019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wats.) and waterhemp (Amaranthus rudis Sauer) control, soybean [Glycine max (L.) Merr.] yield, and net income in conventional, glyphosate-resistant, and glufosinate-resistant soybean production systems. Visual control evaluations 10 wk after emergence at the waterhemp site revealed that all preemergence only applications (PRE-only) and preemergence followed by a postemergence applications (PRE fb POST) provided greater than 92% waterhemp control in either soybean system and at the Palmer amaranth site and all PRE-only provided greater than 83% Palmer amaranth control across soybean systems. Averaged across all herbicide programs at both locations, glufosinate-resistant soybean provided the highest grain yield and net return followed by glyphosate-resistant and conventional soybean systems. Furthermore, with the exception of the conventional PRE-only program at the waterhemp site, all glyphosate-resistant soybean herbicide programs provided greater net return than all conventional herbicide programs. Collectively, the results from both trials indicate that programs containing PRE herbicide treatments provide the best opportunity for season-long control of waterhemp and Palmer amaranth and highest grain yields and net returns in conventional, glyphosate-resistant, or glufosinate-resistant soybean systems. The results from these experiments also suggest that Palmer amaranth may be particularly difficult to control in conventional soybean systems.","PeriodicalId":100342,"journal":{"name":"Crop Management","volume":"12 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1094/CM-2013-0028-RS","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91781945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
