DRY-FARMING ZOXES 



It is highly probable that the method of 

 sowing alfalfa in rows wide enough to 

 permit of inter-tillage will be found to 

 be the best plan for raising forage as well 

 as for seed production. As Mr. Scofield 

 writes in his monograph on this subject: 

 "It is well known that isolated alfalfa 

 plants when allowed to mature on these 

 dry lands produce relatively large quan- 

 tities of seed. This is probably due, in 

 part, to a better illumination on all sides 

 of the plant, resulting in a larger number 

 of flowers, in part to the drier air sur- 

 rounding these flowers during the pol- 

 lenation period, which appears to have 

 some bearing on seed production, and in 

 part to the greater ease of access for in-

 pollenation. It is certainly true that the 

 partial isolation of the plants secured by 

 row planting results in greatly increased 

 yields of seed per plant, and there is
