380 FIELD CROP PRODUCTION 



406. Substitute hay crops. — Failure of the regular 

 seeding or unusual demands for hay may require substitute 

 or supplementary hay crops. Sometimes, too, the mar- 

 ket price of timothy, clover, or alfalfa hay is such that 

 the regular hay crop may be marketed with profit, a 

 substitute crop supplying home needs. Such crops are 

 to be found in the field peas, alone or with oats, millets 

 and sorghums. The time and method of seeding these 

 crops have been discussed in the earlier chapters.
