WHEAT — CULTURAL METHOhS 329 



as the fly lays no more eggs after this date. Wheat sown, 

 in northern Georgia during the last 10 days in October 

 has been found to escape injury from the Hessian 'fly. 

 In sections where the* Hessian fly does not injure wheat, 

 larger yields can be secured by seeding rather early to 

 allow the plants to make a vigorous root-development 

 before cold weather, and to allow the crop to make the 

 maximum utilization of the plant-food in the soil. Duggar 

 suggests the following periods during which the bulk of 

 the wheat crop shquld be seeded in Alabama: 



North Alabama, October 10th to November 1st. 



Central Alabama, November 1st to 15th. 



South Alabama, November 15th to 30th. 



In the wheat-growing regions of Oklahoma, the winter 

 wheat is sown from the 15th of September to the 15th' of 

 October. Field trials by the Oklahoma Station do not 

 indicate much difference between the respective dates'. 

 In north Texas wheat is usually seeded during the latter 

 part of October and the first part of November. 



403. Rate of seeding. — The usual rate of seeding for 

 wheat is from 4 to 6 pecks to the acre. The greater num- 

 ber of experiments on this point indicate that under favor- 

 able conditions, 4 pecks are sufficient when drilled and 5 

 peckg when broadcast. If the seed-bed is poorly prepared, 

 or a poor quality of seed is used, larger amounts should 

 be sown. Also more seed is required for late sowing than 

 for early sowing and more for poor soil than for rich soil. 



404. Methods of seeding. — The methods employed 

 in seeding wheat are (1) broadcast seeding, and (2) seeding 

 in drills 6, 7 or 8 inches apart. 



A review of the experimental evidence on drilling ver- 

 sus broadcasting wheat shows many advantages in favor 

 of drilling, chief of which are: (1) Increased yield. The
