BREEDERS, GROWERS, DISTRIBUTORS 
SESBANIA 
Sesbania macrocarpa 
23 

A native, erect, tall, quick-growing annual summer legume which shows a preference 
for hard-pan soils. Used extensively in irrigated sections for its value as a soil- 
improvement crop. Protects citrus orchards during hot summer weather; used also 
to furnish food for game birds during the fall. Produces an enormous tonnage of 
green succulent growth ready to plow under in 4-6 weeks, when it decays rapidly, 
adding nitrogen and organic matter to the soil, and helping to bring it into good 
mechanical condition. Its rapid growth can crowd out noxious weeds and grasses.

SOYBEANS 
Soja max 
Soybeans are native to the Orient and recently have become of great agricultural 
and industrial 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 development 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 root- 
knot. 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 
acceptance. Very similar to Laredo, except for the color of the seed which is 
red instead of black.
