BEET 

 A loose deep rich fresh relatively cool soil and a con-

 of garden beet. It is usually a companion- or succession-

 to raise. The round varieties are relatively surface feeders 

 and early in growth. The land should be kept well tilled 

 to conserve moisture arid to Tceep down weeds, particularly 

 in the early part of the season. 



Sow in drills as soon as the ground is ready, and thin to 

 5 to 8 in. apart ; the thinnings may be used as greens. The 

 drills should he far enough apart, to admit of wheel-hoe till- 

 age, — 12 to 18 in. Field beets should he far enough apart for 

 horse tillage, 20 to 30 in. Five to eight pounds of seed are 

 required for an acre ; 1 ounce sows 75 to 100 feet of drill. 

 Seed is covered about 1 in. deep. Average crop is 300 to 400 

 bushels to the acre.
