No difference is apparent between a green manuring crop and a bare summer- 

 fallow. Barnyard manure shows a decided advantage over both. 



SEED-BED PREPARATION. 



The purpose of this experiment is to find out the degree to which work in prepar- 

 ing a seed-bed for grain — wheat and oats — may be carried with profit. The wheat was 

 grown on summer-fallowed land, which was uniformly treated, so that the difference in 

 preparation lay entirely in the work done in the spring before seeding. Plot 1 received 

 no spring work; plot 2 received three strokes of the harrow; plot 3 was packed with 

 the surface packer, cultivated with a stiff tooth cultivator, and harrowed four times. 

 The wheat was sown April 19. All plots matured on the same date, though plot 3 

 was one day earlier in heading out.

This experiment was also conducted \\-ith oats so\\,i on wheat stubble. The three 

 plots were equally well ploughed and packed in the fall of 1912. Plot 1 was harrowed 

 once in the spring and sown; plot 2 was harrowed seven times and packed in the 

 spring, the gronnd was hard and rather lumpy, rendering this amount of work neces- 

 'sary to give "good" cultivation; plot 3 was harrowed nine times and packed three 

 times. The oats were sown May 7. jSTo difference in growth could be noted at any 

 time.
