30 ASSOCIATED SEEDS, INC. 
~ SOYBEANS 
Soja max 
Soybeans are native to the Orient and recently have become of great agricultural and indus- 
trial importance in America, many varieties having been developed for diverse purposes. 
Under the growing conditions of south Texas, however, they are only recommended for green 
manure, to which the following varieties are well adapted. They will improve the structure 
of clay soils and build up others low in fertility. Seed should be inoculated before planting. 
It is hoped that the work now being carried on by several agencies will result in the develop- 
ment of other varieties with wider uses in this territory. 
LAREDO 
Introduced from China in 1914 by U. S. Department of Agriculture. Recognized as the 
best adapted variety for drier climates of Texas. Quite cold hardy, and well adapted for 
early and late planting. Highly resistant to wilt and rootknot. Plants erect, branching 
freely, with fine stems; seed, very small, flat, black. 
RED TANNER 
A more recently developed type for southern conditions which has quickly gained accept- 
ance. Very similar to Laredo, except for the color of the seed which is red instead of black. 

Our main plant at San Antonio 
VELVET BEANS 
Stizolobium spp. 
Velvet beans produce a greater growth than any other summer annual legume planted for 
forage and soil improvement in the high rainfall belt of southeastern Texas. Immune to wilt 
and rarely attacked by root-knot, the species is more adaptable than cowpeas on rich soils in 
warm moist climates. Responds to irrigation and smothers out undesirable weeds, brush and 
grasses. Cattle and hogs graze and fatten on the matured seed in winter. The development and 
introduction of bunch types has increased the range of adaptability of this valuable legume. 
EARLY SPECKLED 
The most extensively grown sort, with long trailing, coarse, viny stems often 20 feet in 
length and dense growth of large leaves. The grape-like clusters of showy purple blossoms 
are attractive.
