“…Ciha (1982) reported that a cultivar × tillage system interaction was not detected for grain yield and quality when four barley cultivars were grown under CT, NT, and a "conservation" or RT system in the Palouse region in southeastern Washington. Conversely, Therrien and Grant (1998) detected a cultivar × tillage interaction for grain yield of six barley cultivars grown under CT and NT following canola (Brassica spp.) and CT following summer fallow in western Manitoba.…”

Malt barley (Hordeum vulgare L.) production is shifting in the Great Plains from conventional clean-tillage (CT) methods to reduced tillage (RT) and no tillage (NT). This study aimed to determine the effect of tillage on the relative ranking of malt barley cultivars for yield components, grain yield, and quality. Six barley cultivars were grown in southwestern North Dakota from 2010 through 2013 under long-term CT, RT, and NT. Ranking of cultivars did not change across tillage systems for plant density, plant height, or spike density (P > 0.05). Likewise, a tillage × cultivar interaction was not detected for grain yield, except in 2012 (P = 0.007) when dry conditions developed and persisted. That year, the grain yield of cultivars Pinnacle and Conrad were 5160 and 4970 kg ha -1 under NT management compared with 4170 and 3730 kg ha -1 under CT. Yield of other cultivars was unaffected by tillage system in 2012. Tillage × cultivar interactions were detected for grain protein concentration and test weight; however, one or more cultivars consistently produced grain with quality traits that were comparable or superior to those of other cultivars in each tillage system. Grain protein concentration decreased from 131 g kg -1 under CT to 113 g kg -1 under NT across years and cultivars, whereas grain test weight was sometimes heavier under NT. The results of this research indicate that cultivar recommendations can be extended across long-term contrasting tillage systems when malt barley is grown in the Great Plains.

“…T he replacement of conventional or clean tillage (CT) with conservation tillage and particularly no‐tillage (NT) practices in the northern Great Plains is well documented (Therrien and Grant, 1998; Hansen et al, 2012). The enhanced precipitation‐use efficiency resulting from adoption of NT enabled farmers to intensify cropping systems, replacing traditional crop‐fallow with rotations where crops are grown annually (Anderson et al, 2003).…”

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.

“…Yield is considered to be very low for cereals grown in developing countries compared with harvests in developed countries (Jaradat and Haddad 1994). Low barley yield is attributed to limited and uneven distribution of precipitation, poor soil moisture conservation, improper cultural practices, poor crop stands and weed competition (Therrien and Grant 1998).…”

Experiments were conducted to evaluate the effect of mouldboard-or chisel-ploughing and rotations on barley crops and associated weeds in a semi-arid location. Two primary soil tillage operations and eight crop rotation-tillage operation combinations were evaluated over two successive seasons. Drought conditions prevailed (<152 mm annual precipitation) and affected the measured parameters. Barley grown in mouldboard-ploughed plots had higher biomass compared with chisel-ploughed plots. Barley grain yield was greater in mouldboard-ploughed plots in a fallow-fallowbarley rotation. Weed species densities varied between tillage systems and rotations. Density of Hordeum marinum, for example, was high in fallow-barley-fallow in chisel-ploughed plots, and was high under more continuous fallow in mouldboard-ploughed plots. Similar variations were also observed in weed fresh weights and in numbers of seed produced. The results describe the productivity of barley under extremely dry conditions, where an advantage for mouldboard ploughing was observed. The results also indicate the complexity of weed communities in their response towards different tillage-rotation combinations.
