EXPERIMENTS IN FIELD PLOT TECHNIC 15 



in four plots each, as shown in figure 3. The rows were 14 feet long 

 and were cut to 12 feet in harvesting. This is a convenient size of 

 plot for oats tests with 10 inches distance between rows, when the 

 border rows are discarded, since the total yield of three rows in 

 grams, divided by 10, gives the yield in bushels per acre. The oats 

 were planted at the rate of 10 pecks per acre, on March 18, in rows 

 running north and south. The season was favorable and a good yield 

 of the better varieties was obtained. The yields of the 24 varieties 

 replicated four times are shown in Table 2. 



The oats strain test was conducted on the same field, as shown in 

 figure 3, directly south of the oats variety test. In planting, these two 

 tests were handled as one ; and the rate, date, and method of planting 

 were the same. The strains tested were 15 strains of oats obtained 

 under the name Red Rustproof from various experiment stations and 

 seedsmen. Three of these strains, 0121, 0124, and 0127, were not true 

 to name, but the remainder were taxonomically Red Rustproof oats, 

 as described by Etheridge 3 . The oats strains were tested in six series, 

 with check plots in every sixth plot. The line of check plots on the west, 

 however, gave abnormally low yields, probably because they were 

 located partly on a dead furrow at the edge of the experiment field. 

 On account of shortage of seed some of the varieties could not be 

 planted in the last series. The first and last series were therefore dis-
