THE SOYBEAN \’ARlETY TESTS l
The soybean variety performance reports for 1963 are based on a planting made
by ti. R. Richards on the farm of Allan Toy, 3 miles south of Henderson, through the
cooperation of the Henderson County Extension Agent Stuart Brabant; the Owensboro _, 
Grain Co. , Owensboro; and Ellis Elevator Co. and Henderson Elevator Co. , of
Henderson. Several of these varieties and 18 other experimental strains were also
planted in the Uniform Tests of the U. S. Regional Soybean Laboratory, Urbana, Ill.
METHODS USED
The varieties were planted in four—row plots with three replications. The rows
were if) feet long and 40 inches apart. A l6»· foot seeti on was harvested from each of t
the two center rows. Beans were planted at a rate ol` approximately 12 seeds per foot; ·
of row. The plants were cut by hand and the lncans th reshed with a nursery thresher.
Ther beans were cleaned of trash and let stand in the laboratory until they had reached
a constant moisture content before plot weights were taken. The moisture content `
when weighisd was about 10 percent. .»\ei·e yields were calculated and are reported on
an :iir—di‘,v basis. _ V
.\milna·n hand treated over the row. and timely cult.iva.ti ons kept weeds at a V
minimum. l
Oil content and protein content were determined by the U. S. Regional Soybean
l,:il.»orat.ory and the i"niycrsit:$,i· of Kentucky Depart.inent of Feed and Fertilizer and the
Depxiriinent of Agronomy Service .l..:ilc»or:.it‘oi·y.
*l».odgi_ng·_ notes were recordc d rt or new: m:iturit.v when the height was also

the soybeans tended to dry up ratln—r tli:in mriture. so too much emphasis should not
be placed on the recorded maturity due to the abnormally dry weather.

wrinkling and the relative 1ippe:ir:iiie· of the seed n‘<~i·e taken into account in rating for
quality.
