Table 1. Yield and
agronomic charateristics in an irrigated barley variety trial
Most
malting barley is grown under irrigation in the Western states. Irrigation allows producers to achieve yield
goals resulting in better N utilization and improved quality. Historically barley has played a significant
role in the agriculture of central and eastern ND as cash crop that fit well
into the rotation. Recently barley
acres in this area of the state have declined due to disease pressure and
quality considerations. With the use of
intensive crop production techniques (fungicide applications, split N
applications, etc.) high yields of high quality barley can be achieved.
The
objective of this study is to find barley varieties that are viable in
irrigated cropping systems in Southeastern ND and to develop and demonstrate
agronomic practices that promote barley production.
|
Soil: |
Embden sandy loam and Hecla sandy loam; pH=7.1;
2.8% organic matter; soil-P and soil-K was very high and soil-S was high. |
|
Previous crop: |
2006 – onion; 2005 – field corn; 2004 – cabbage, carrot, edible bean, field pea, mustard, millet,
soybean, sweet corn and wheat. |
|
Seedbed Preparation: |
Fall coulter chisel. Multiweed (field cultivate) April 18 to smooth the seedbed. |
|
Planting: |
Planted on April 18. Planting rate was 2.9 bu/acre (1,600,000 seeds/acre). |
|
Plots: |
Plots were 68 ft long by 7 ft wide. There were four reps. |
|
Fertilizer: |
November 2006, broadcast 9 lbs N/acre, 43 lbs P2O5/acre,
101 lbs K2O/acre and 13.5 lbs S/acre as 11-52-00, 0-0-60 and
90% elemental sulfur.
Side dress 60 lbs N/acre on May 7 and 50 lbs N/acre on May 22 as
32-0-0. |
|
Irrigation: |
Overhead sprinkler irrigation as needed. |
|
Pest control: |
Apply Wolf Pak (1.35 pt/acre on May 7), Axial + Adigor
(8.2 oz + 9.6 oz/acre on May 23.
Apply Headline (6 oz/acre on May 22), Tilt (4 oz/acre on June 4)
and Folicur (2 oz/acre) +
Proline (2 oz/acre) on June 15 and June 16. |
|
Harvest: |
Harvested on July 19 with a Hege plot
combine. Harvest area was a five-foot
section from the middle of the plot 68 feet long. |

Yield was not significantly
different between varieties. Lodging which is usually a serious problem in
irrigated barley in southeastern ND was not evident in 2007. Warm dry weather and conservative N
application were factors that helped limit lodging. A high percentage of plump kernels, good test weight and low
protein show high quality malting barley at profitable yield levels.
