FORAGE-CROP EXPERIMENTS AT SAN ANTONIO. 23 



(Golden Vine) were seeded with a grain drill. Nos. 18806 and 30307 

 were completely destroyed by the unusually severe winter, but No. 

 30134 came tlirough with practically a perfect stand. The hay yield 

 from this planting was at the rate of 2,783 pounds per acre and the 

 grain yield. 14 bushels. The hay yield in this instance does not 

 represent what it would have been had the vines not been allowed 

 to mature. The vines were so ripe when cut that the greater part of 

 the leaves dropped off.

Four species of Stizolobium bearing S. P. I. numbers were tested in 

 2-rod rows in 1910 and gave promise of being desirable legumes for 

 this section. No. 24870 (the Bengal bean, Stisolohium aterrimum) 

 and No. 25715 (the Florida velvet bean, S. deeringianum) were the 

 most promising. The only objection to this legume which has been 

 suggested is its slow growth. From the time of planting to the 

 flowering of S. deeringianum 164 days intervened. The quantity of 

 forage was much greater than that produced by any other legume 

 that has been on trial. 



MILLET. 



As was noted in a previous publication/ millet may be used to 

 advantage as a catch crop when an early crop of hay is desired or 

 when the seasonal rains are very late. A crop may be matured in 

 40 to 60 days, and a yield as high as 1 to 1 J tons of hay per acre has 

 been obtained from the better varieties of early-maturing millet. 

 The slower growing varieties give, as a whole, a somewhat larger yield 

 per acre under favorable moisture conditions, but they are not so sure 

 of maturing as the early ones. On the whole, millet is not as desir- 

 able as many other forage plants, because of its lack of drought 

 resistance. Table XIX shows the yields of the varieties tested in 

 1908.
