Difference between Winter Wheat and Spring 



Wheat. 



It has been maintained by writers on wheat culture 

 that the distinction between winter and spring wheat 

 is one which arises entirely from the season in which 

 the seed has usually been sown ; and that they can 

 readily be converted into each other by sowing earlier 

 or later, and gradually accelerating or retarding their 

 growths. If a winter variety is caused to germinate 

 slightly, and then checked by exposure to a low tem- 

 perature, or freezing, until it can be sown in spring, 

 some writers have asserted that it may be converted 

 into a spring wheat. 



It requires a long time to change winter wheat into 

 a spring crop. Still, it can be done, by persevering for 

 half a dozen successive years. The usual way to change 

 a winter wheat to spring variety is, to put in the seed 

 a month later every season, until the period of vernal 

 seed-time is reached. This makes it necessary to sow 

 wheat during the winter months. But the desired 

 object can be accomplished in a much more expeditious 

 way than to sow seed in December, and the product 

 of that crop, the next January, and the next season in 

 February, the next in March, and the next in April.
