with twelve loads of barnyard manure per acre ; another with five 

 Ions of green vetch per acre ; and the third having received no fer- 

 tilizer. See Table XCIV. Crusting of the surface soil, because 

 of a shower which fell soon after planting, prevented seed from 

 comeing up in the plot which had been green manured. The ma- 

 nured plot returned a slightly heavier yield than the unfertilized.

1 — Failed to emerge. 



To determine the optimum depth to plow, twelve plots of 

 Dwarf milo were planted July 31, 1915. One plot previously had 

 been disced and another dynamited with a half stick of 40 per cent 

 strength powder placed every fifty feet. The dynamited ground 

 was not well loosened, and about three times as many charges 

 should have been used. The remaining ten plots were plowed July 

 *30, at depths ranging from three to twelve inches. The best yields 

 were obtained from plots which had been deeply plowed. See 

 Table XCV.
