Soybeans
are a major dryland crop in central and southeastern North Dakota. Historically dry edible beans have
pre-empted soybeans in irrigation rotations in this area of the State. The present market price for soybeans and
less risk in their production have resulted in more irrigated acres. This trial was initiated to provide
producers with yield and agronomic information on soybean varieties in an
irrigated environment.
MATERIALS AND METHODS
Soil: |
Maddock sandy loam and Embden sandy
loam; pH=7.3; 1.8% organic matter; soil-P was very high, soil-K was medium
and soil-S was medium. |
Previous crop: |
2006 ‑ field corn; 2005 ‑
cabbage, carrot, onion and potato; 2004 ‑ sweetcorn. |
Seedbed Preparation: |
Flailed, disked and coulter chiseled in the fall; Coulter chisel
lightly once on April 26. Multiweed (field cultivate) twice on May 8
to smooth the seedbed and to incorporate herbicide. |
Planting: |
Planted soybeans on May 16 in 30-inch
rows. All beans were inoculated just
prior to planting. |
Plots: |
Plots were 17 ft long by 10 ft (4
rows) wide. There were 4 reps. |
Fertilizer: |
November 2006, broadcast 9 lbs N/acre, 43 lbs P2O5/acre,
101 lbs K2O/acre and 13.5 lbs S/acre as 11-52-0, 0-0-60 and
90% elemental sulfur. |
Irrigation: |
Overhead sprinkler
irrigation as needed. |
Pest control: |
Trust (1½ pt/acre) on May 8, and Fusilade (8
oz/acre) + MSO (1pt/acre) on June 28.
Glyphosate Original (1qt/acre) + NIS (0.05%v/v) + AMS + (1 lb/10 gal)
on June 5, Cornerstone (40 oz/acre) + AMS (1 lb/10 gal) on June 29,
Cornerstone (48 oz/acre) + AMS (1 lb/10 gal) + NIS (0.5%v/v) on July 7; for
weed control. Topsin (1 lb/acre) on July
3 and July 11 for disease control.
Lorsban (1 pt/acre) on August 3 for insect control. |
Harvest: |
Harvested on October 4 with a Hege
plot combine. |
Yield,
test weight, flowering date, maturity date and lodging were significantly
affected by variety. Forty varieties
averaged 67.5 bu/acre. The difference
between the lowest and highest yielding variety was only 13.2 bu/acre. This is surprising since maturities ranged
from a group 0.007 to a group 1.5.
