PREVIOUS CROP: Wheat, cucumbers, and hay

LAND PREPARATION: Disked and field cultivated

DATE PLANTED: 3-21-07 with cones mounted on an ALMACO planter using JD Max-Emerge II units

PLOT LENGTH: 26’

FERTILIZER: Applied preplant 120-40-20-20(S) as 15-5-2.5-2.5 + 1 qt/A Zn

HERBICIDE: Applied 1.0 qt/A Dual + 1.5 qt/A Atrazine, post-plant

RAINFALL: Rainfall was not recorded at the test site, but was considered substantial throughout the growing season.

IRRIGATIONS: 1” of irrigation water was applied by a linear system during the growing season.

DATE HARVESTED: 8-27-07, with a JD 3300 plot combine equipped with Grain Gauge.

SIZE HARVESTED PLOT: 2 rows, 26' long

TEST DESIGN: Randomized complete block

NUMBER ENTRIES: 35

NUMBER REPLICATIONS: 4

NUMBER ROWS/PLOT: 2

MEAN PLANT POP: 19,851 plants/A

TEST MEAN: 165.4 bu/A; yields corrected to 15.5% moisture

TEST C.V.: 7.40%

COMMENTS: Timely rainfall and good agronomic practices were contributing factors that resulted in outstanding yields, despite several weather related events.

Excellent moisture conditions were present for the March 21 planting date. After emergence, the test block suffered a brief period of cold temperatures that retarded early plant growth and development. However, warm temperatures soon followed resulting in good plant growth. Continuous plant growth and development resulted from ample rainfall and an excellent fertilization program.

In early-May, approximately 10 days prior to tasseling, a severe wind storm “snapped” plants near ground level in some plots. Severe damage occurred in some plots, thus affecting final yields. Prior to harvest, plant counts were made from each plot, but may have not accounted for all of the stalk breakage.

Due to ample rainfall throughout the growing season, only one inch of irrigation water was applied to the test block.

The test mean yield was 165.4 bu/A compared to the past 3-year average of 148.7 bu/A. Six hybrids produced over 180 bu/A. Excellent bushel weights were attained as reflected in the following table.

Appreciation is expressed to Mr. Jason Ott for collecting flowering data and for his assistance in planting the test block.
