NURSERY EXPERIMENTS. 



The nursery experiments witii barley consisted almost entirely of 

 tests of varieties. No promising varieties not already being grown 

 in plats were observed in the nursery experiments. Progenies from 

 a few natural hybrids of barley found in the plats at Newell were 

 grown for observation. The strains isolated w^ere not as promising 

 as other varieties previously mentioned. 



RATE-OF-SEEDING EXPERIMENTS. 



Rate-of-seeding experiments w^ith White Smyrna barley, C. I. No. 

 658, were begun in 1917 and conducted for three years. The barley 

 was sown at four different rates, ranging from 4 to 10 pecks per acre. 

 The data are not entirely conclusive, but are of considerable interest. 

 The yields are shown in Table XXIV. 



The highest average yield was obtained from the plats sown at the 

 rate of 4 pecks per acre. In 1917, however, the 8-peck rate gave the 

 highest yield. The barley in the varietal experiments usually has 

 been sown at the rate of 5 pecks per acre, and from the average re- 

 sults shown in Table XXIV this rate appears to be ample. On a 

 well-prepared seed bed the sowing of 4 pecks of clean barley seed 

 per acre apparently is sufficient.
