Malt barley yield and quality affected by irrigation, tillage, crop rotation, and nitrogen fertilization. Agronomy Journal. 107(6):2107-2119. doi:10.2134/agronj15.0027Interpretive Summary: Malt barley is an important cash crop usually rotated with sugarbeet to reduce incidences of weeds, diseases, and pests in irrigated cropping systems in the northern Great Plains. Malt barley is also widely grown in dryland cropping systems in this semiarid region where the growing season is relatively short due to cool climate with lower precipitation than in other regions. Little is known about the comparison of management practices on malt barley yield and quality in irrigated and non-irrigated cropping systems. 
We evaluated the effects of irrigation, tillage, cropping system, and N fertilization on malt barley yield and quality in a sandy loam soil from 2005 to 2011 in croplands converted from Conservation Reserve Program in western North Dakota. Treatments were two irrigation practices (irrigated vs. non-irrigated) as the main plot and five cropping systems (conventional till malt barley with N fertilizer [CTBN], conventional till malt barley without N fertilizer [CTBO], no-till malt barley-pea with N fertilizer [NTB-P], no-till malt barley with N fertilizer [NTBN], and no-till malt barley without N fertilizer [NTBO]) as the split plot treatment arranged in a randomized block design with three replications. 
Malt barley biomass and grain yields were greater with NTB-P than CTBO, NTBN, and NTBO in the irrigated practice and greater with NTB-P and NTB-N than NTBO and CTBO in the non-irrigated practice. Compared with CTBO and NTBO, grain protein concentration was greater with CTBN in the irrigated practice and greater with NTB-P in the non-irrigated practice. Compared with NTB-P, grain plumpness was greater with CTBO in the irrigated practice and CTBN in the non-irrigated practice. Plant stand, biomass yield, grain plumpness and test weight were greater, but protein concentration was lower with irrigation than without. 
Malt barley yield and quality can be sustained by using NTB-P compared with the traditional CTBN, regardless of irrigation practices. This management practice can also help to improve soil and environmental quality.

We evaluated the effects of irrigation, tillage, cropping system, and N fertilization on malt barley yield and quality in a sandy loam soil from 2005 to 2011 in croplands converted from Conservation Reserve Program in western North Dakota. Treatments were two irrigation practices (irrigated vs. non-irrigated) as the main plot and five cropping systems (conventional till malt barley with N fertilizer [CTBN], conventional till malt barley without N fertilizer [CTBO], no-till malt barley-pea [Pisum sativum L.] with N fertilizer [NTB-P], no-till malt barley with N fertilizer [NTBN], and no-till malt barley without N fertilizer [NTBO]) as the split plot treatment arranged in a randomized block design with three replications. Malt barley biomass and grain yields were greater with NTB-P than CTBO, NTBN, and NTBO in the irrigated practice and greater with NTB-P and NTB-N than NTBO and CTBO in the non-irrigated practice. Compared with CTBO and NTBO, grain protein concentration was greater with CTBN in the irrigated practice and greater with NTB-P in the non-irrigated practice. Compared with NTB-P, grain plumpness was greater with CTBO in the irrigated practice and CTBN in the non-irrigated practice. Plant stand, biomass yield, grain plumpness and test weight were greater, but protein concentration was lower with irrigation than without. Malt barley yield and quality can be sustained by using NTB-P compared with the traditional CTBN, regardless of irrigation practices.
