FORAGE-CROP EXPERIMENTS AT SAN ANTONIO.

the beginning of the growing season. Early-maturing sorts like the 

 Red Amber crowd out the cowpeas. 



The yields from the plats of sorghum indicate that fully as much 

 fodder can be obtained in the mixture as by seeding alone; therefore, 

 the advantage derived from the admixture of the cowpea hay, if 

 not obtained at too great an expense in seeding and cultivation, is 

 well worth while.

 made by both the cowpeas and the sorghum. There are about three plants of the sorghum to four of 

 the cowpeas. (Photographed July 27, 1910.) 



SMALL GRAINS AS FORAGE CROPS. 1 



While in the immediate vicinity of San Antonio the grain yields 

 from such cereals as oats, barley, wheat, and rye are low, yet oats, 

 and rye to a lesser extent, are quite extensively grown for forage. 

 Oats are also very useful for whiter pasturage, and are generally a 



' The growing of cereals for grain production only at low altitudes in the vicinity of San Antonio is not a 

 profitable venture. The principal cause of low yields is the susceptibility of grains to rust. In higher alti- 

 tudes cereals are grown to a considerable extent. In the high land near Kerrville, and even no farther 

 distant than the town of Boerne (30 miles), satisfactory yields have been realized from wheat and>oats.
