The rate of seeding will also vary both with the 

 latitude and with the method of seeding practised. 

 Generally speaking, it has been shown advisable to 

 seed oats at the rate of from 6 to 10 pecks per acre, 

 the rate depending largely on the type of soil on which 

 they are sown, the method of seeding practised, and 

 the use to which the crop is put. The Ohio Station in 

 a series of tests covering eleven years found that with 

 all varieties of all types tested, a seeding of eleven 

 pecks per acre was advisable. Where clover is seeded 

 with oats as a nurse crop, as is often done, a lighter 

 seeding is desirable than would otherwise be given 

 were the oats sown alone.
