Agriculture. It belongs lo the Peterkin group, and has long 

 basal limbs and long slender fruit limbs. Its bolls are medium 

 size, and it requires about 70 to make a pound of seed cotton. 

 They are easily picked. The seed are small and fuzzy; the 

 percentage of lint to seed is 35; its fiber is about 7-8 an 

 inch long. Dixie is thought to be rather late for boll weevil 

 conditions. It is a resistant variety and produces well under 

 ordinary conditions. 



DIX-AMFI. 



Dix-Afiti is a hybrid made by Mr. A. C. Lewis, of the Georgia 

 State Board of Entomology, by crossing Dixie on Mit-Afifi. 

 The last named variety is an Egyptain cotton found to be very 

 resistant to nematodes. This hybrid resembles Dixie type of 

 plant. The bolls are medium size, easy to pick, but mature 

 late. The fiber is long and silky; the percentage of lint to 

 seed is about 30. 



Thi-s Station has no seed for sale of any of the above varie- 

 ties, but can furnish, on application, lists of growers of most 

 resistant varieties. 



RECOMMENDATIONS FOR CONTROLLING COTTON WILT 



AND ROOT-KNOT. 



The cotton wilt fungus seems to attack only the cot- 

 ton plant, and fortunately it may be starved out by a 

 judicious rotation of crops. 



The choice of crops for a rotation is important where 

 the land is infested with nematodes and wilt. No crop 

 or variety that encourages the multiplication of 

 nematodes or wilt should be introduced into the 

 rotation. A few of the crops that increase the number 

 of nematodes are most varieties of cowpeas, (except 

 Iron and Brabham), sweet potatoes, soybeans, vetches, 

 clovers, sugar cane, melons, and most garden vegeta- 

 bles. Some crops that tend to starve out nematodes and 

 wilt are corn, oats and other grains, grasses, sorghums, 

 velvet beans, peanuts, beggar weed, and Iron and Brab- 

 ham cowpeas. For infected land the following three- 

 year rotation is suggested : 



1st year — Plant corn and between the corn rows 

 or hills plant Iron or Brabham cowpeas. Where 

 early autumn pasture for cattle is desired, vel- 

 vet beans may be planted with the corn and grazed 

 while green and in time to sow a fall grain crop. 



2nd year— Plant oats; after the grain is cut for hay or 

 seed, plant the stubble in Iron or Brabham cowpeas for 

 hay or seed. Follow this with some winter grain for a 

 cover crop.
