THE SMALL GRAINS 163 



was prepared for wheat in eleven different ways. In each case 

 the seed, manner of seeding, and kind of ground was the same. 

 The only difference was in the time and method of preparing the 

 ground. The results are given in the following statement : 



No. i. The ground was disked only, before planting. The aver- 

 age cost of preparing the ground was $2.07 per acre, and the yield 

 was 6.63 bushels, which at the market price when threshed was 

 worth $5.71, leaving a balance of only $3.64 per acre to pay for 

 the cost of seed, seeding, harvesting, and marketing and to pay a 

 profit to the grower. 



No. 2. The ground was plowed 3 inches deep (too shallow) 

 September 15 (too late for best results). The average yield in 

 this test was 13.24 bushels, worth $11.18, and the cost of prepa- 

 ration was $2.83, leaving a balance of $8.35 per acre with which 

 to meet expenses and pay a profit. 



No. j. Ground was plowed 7 inches deep in September. A yield 

 of 1 4. 1 5 bushels, worth $i 1.93, was obtained. The cost of plowing 

 and preparation of the ground was estimated at $3.33, leaving a 

 balance of $8.60. 



No. 4. Land was double disked July 1 5 to kill weeds and pre- 

 vent evaporation of moisture, and plowed 3 inches deep Septem- 

 ber 15. The average yield was 19.71 bushels, worth $16.30. The 

 cost of preparing the ground was $3.93, leaving a balance of $i 2.37. 



No. 5. August 1 5 the plot for this test was plowed 7 inches 

 deep and worked afterwards sufficiently to kill weeds and con- 

 serve moisture. The cost of preparation was $4, the yield 22.19 

 bushels, worth $20.34, leaving a balance of $16.34. 



No. 6. August 15 land was plowed 7 inches deep, but was 

 not worked until September 15. The cost of preparation was 

 $3.33, the average yield 20.48 bushels, valued at $16.98, leaving 

 a balance of $13. 65. As the preparation of the seed bed in this 

 test was identical with No. 5, except that the ground was not 

 worked for a month after plowing, the early disking was worth 

 $3.36 per acre. 



No. j. July 15 (right time) land plowed 3 inches deep (too 

 shallow) produced an average yield of 20.17 bushels, worth $17.10. 

 The cost of preparation was $4.85, leaving a balance of $12.25 

 per acre.
