WHEAT, OATS, CORN A BETTER SEQUENCE ON SPRING PLOWING THAN 

 OATS, WHEAT, CORN AT MOST STATIONS. 



In Table "XXIX a comparison of rotations Nos. 2 and 9 shows that 

 when spring plowing is practiced the wheat-oats-corn sequence gives 

 better results than the oats- wheat-corn sequence, Highmore and Belle- 

 fourche, S. Dak., and Judith Basin, Mont., being the only stations 

 where the latter sequence gives better results than the former. 



In Table XXX the same comparisons have been made between 

 rotations Nos. 1 and 4. In these rotations the corn stubble was 

 disked instead of plowed and the two other plats in each of the 

 rotations were fall plowed instead of being spring plowed, as were 

 rotations Nos. 2 and 9. 



The results of this comparison agree in a general way with those 

 of rotations Nos. 2 and 9, but are less markedly in favor of the corn- 

 wheat-oats sequence, the net gain of this sequence being only 22 

 cents instead of 82 cents per acre. The four tests giving results in 

 favor of the corn-oats- wheat sequence in Table XXIX also gave 

 like results in Table XXX. There are, however, three additional 

 tests in the latter comparison in favor of the corn-oats- wheat sequence, 

 i. e., Highmore, 1907, North Platte, 1907, and Amarillo, 1908.
