Most
malting barley is grown under irrigation in the Western states. Irrigation allows better utilization of N and
improved quality. Historically, barley
has played a significant role in the agriculture of central and eastern ND as a
cash crop that fit well into the rotation.
Recently a perception exists that barley, especially malting barley is
not a viable crop in this area of the state due to disease, low yields, low
price and quality considerations.
In reality, production numbers, and
current research on barley production show a different picture. The USDA North Dakota Agriculture statistics
Service show that from 2000-2004 the north central, central and southeast
(excluding Richland and Sargent Counties) regions
produced 35,974,000 bushels of barley annually, which is 40% of the barley
produced in ND. The statistics for 2005
show this area of the State producing 41% of the State’s barley. Intensively managed barley variety trials at
the
The objective of this study is to find barley varieties that are viable
in irrigated cropping systems in
|
Soil: |
Embden loam; pH=6.6; 2.7% organic matter; soil-P,
soil-K and soil-S were very high. |
|
Previous crop: |
2005 - cabbage;
2004 - field corn; 2003 - sweet corn. |
|
Seedbed Preparation: |
Fall disk.
Multiweed (field cultivate) April 12 to
smooth the seedbed and to incorporate fertilizer. |
|
Planting: |
Planted on April 13. 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: |
On
April 10, broadcast 20 lbs N/acre, 45 lbs P2O5/acre, 51
lbs K2O/acre and 13 lbs S/acre as 21-0-0-24, 11-52-0 and
0-0-60 and on April 12 applied 50 lbs N/acre as 28-0-0. Stream-bar 30 lbs N/acre as 28-0-0 on May
15. |
|
Irrigation: |
Overhead sprinkler irrigation as needed. |
|
|
Applied Wolf Pak (1.2 pt/acre on May 13),
Puma (0.4 pt/acre on May 15). Apply
Headline 6 oz/acre on May 17), Tilt (4 oz/acre on June 5) and Folicur (2 oz/acre on June 12 and June 13). |
|
Harvest: |
Harvested on August 23 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 among varieties. Lodging which is usually a serious problem in irrigated barley in southeastern ND was not evident in 2006. 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.
