MATERIALS AND METHODS
|
Soil: |
Embden sandy
loam, Helca sandy loam and Maddock sandy loam; pH=6.8 to 6.9; 2.0% to 2.6%
organic matter; soil-P and soil-K were very high; soil-S was medium to high. |

Seedbed Preparation: |
Disk on April
24. Multiweed (field cultivate) twice
on May 9 to smooth the seedbed and to incorporate herbicide on the
conventional beans. Disk area for
roundup ready beans on May 16 and multiweed all soybean ground |
|
Planting: |
Planted
Conventional soybeans on May 16 and roundup ready beans on May 17 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 3 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. |
|
Irrigation: |
Overhead sprinkler irrigation as needed. |
|
Pest control: |
Conventional
soybean: Treflan (1 pt/acre on May
9), Valor (2.5 oz/acre on May 18) and Fusilade + MSO (8 oz/acre + 1pt/acre on
June 28). Warrior (3 oz/acre on
August 24) to control soybean aphid. Roundup ready: Glyphosate
Original + NIS + AMS (1qt/acre + 0.05%v/v + 1 lb/10gal on June 1, June
18 and August 3). Lorsban (2 pt/acre
on August 24) to control soybean aphid. |
|
Harvest: |
Harvested on
October 2 with a Hege plot combine. |
