FOKAGE-CKOP EXPERIMENTS AT SAN ANTONIO. 



17 



Since the Appier Kustproof oats proved to be the best, m the fall of 

 1909, 39 half-bushel lots of these oats were sent to different farmers in 

 the San Antonio region. Later a circular letter was sent out, request- 

 ing a report on the results obtained with the variety, and its value as 

 compared with the variety ordmarily grown. Twenty-six replies 

 were received, of which 11 were favorable, 3 unfavorable, and the 

 remainmg 12 equally divided — 6 did not think the test was satisfac- 

 tory, and 6 found little difference between this variety and that com- 

 monly grown. 



In 1909 a rate-of -seeding test was made to determine the rate that 

 would give the highest yield. The varieties of oats planted were 

 Appier Rustproof and Culberson Winter. Table XII presents the 

 results of the test.

Apparently conflicting results were obtained in this test. With 

 fhe Culberson Winter oat-s the lightest seeding nearly doubled the 

 grain yield and gave an increased yield of 560 pounds of hay. With 

 the Appier Rustproof oats, however, the heaviest seeding 3"ielded 

 5.62 bushels of grain and 400 pounds of hay more than the lightest. 

 By taking a count of the oats it v\"as found that there were about 

 two and one-half times as many seeds of the Culberson Winter oats 

 as there were of the Appier Rustproof oats in a single pound, so that 

 in the heaviest seeding of the latter the number of seeds per acre was 

 only slightly greater than the lightest seedmg of the former. 

 Although it is to be expected that the seasonal variations will change 

 the results somewhat, yet the results from the season of 1909 indicate 

 that 2 bushels of seed per acre is about the right quantity to sow. 

 This test shows conclusively that the same rates of seeding of two 

 varieties are not necessarily comparable and that the size and weight 

 of the seed are important factors to be considered. 



For further information as to the best rate of seeding this experi- 

 ment was repeated in 1910. Table XIII shows the yields for the year.
