The 2000 Northeast Texas Variety Trial was conducted in Ivanhoe, TX. The soil had pH 8.3 and consisted of
27% sand, 56% silt, 17% clay, and 1.1% organic matter. The plot area received 25 lbs. K2O/acre before planting.
Please see tables for yield results. Thirty-four soybean cultivars were planted on 12 May 2000. Plots were 20 feet long
and 8 rows wide using 14-inch rows (plot area was approximately 187 sq. ft.). Seeding rate was 5 per foot or about
187,000 seed per acre but final stands were about 4 per foot or 149,000 plants per acre. Seed were inoculated with
Cell-Tech 2000 liquid inoculant minutes before planting. The experiment was a split-plot with three replicates. Main plots
were herbicide treatment and subplots were cultivars. The herbicide treatments were Roundup (glyphosate) only or
conventional herbicide. Roundup (glyphosate) was applied on 29 May at 1.5 pints/acre. For the conventional herbicides,
Scepter (imazaquin) was applied pre-emerge on 12 May at 2.8 ounces/acre, followed by Fusilade DX (fluazifop-P-
butyl) at 0.71 pints/acre on 24 May. Also, on 20 June, conventional plots received Reflex (fomesafen) at 1 pint/acre.
Asana XL was applied on 7 June at 0.5 pints/acre. Asana XL at 0.5 pints/acre and 1 pints/acre of Lorsban 4E were
applied on 16 July. Rain was plentiful through June 30, but there was no rain received in July or August. All plots were
end trimmed to 11 feet and harvested within a week of growth stage R8 (defined as the maturity date). The center four
rows from each plot were harvested with a mechanical plot harvester. Seed moisture was determined on all plots and
weights were adjusted to 13% moisture.
