Farmers' Cooperative Experiments. 465 



Corn. — Test of varieties. Packages of each of three varieties will 

 be furnished by the College, to be planted on a definite area and crop 

 weighed. 



No. 5. SiuiHoivcr in corn for silage. Seed will be furnished for a test. 



No. 6. Soy Beans. — A test of several varieties with a view to 

 determine adaption to growing with corn to improve the quality of silage. 



(Experiments at the Cornell station indicate that this desirable natural 

 Stock food may be grown to advantage in New York.) 



No. 118. Spraying for wild mustard. — Mustard can be easily killed 

 by proper spraying with copper sulphate or iron sulphate. Correspond- 

 ence solicited. 



No. 109. Mangels. — A test of mangels as a partial substitute for 

 purchased concentrated feeds. 



Some experiments have seemed to show that a pound of dry matter in 

 mangels has about the same feeding value as a pound of grain feeds. 

 Mangels may be looked upon as equivalent to the concentrates plus 

 water. At this experiment station in 1904-5 they have given over twice 

 as much feeding value per acre as the same land would produce in corn. 

 The labor required to grow them is considerable. Mangels have a special 

 value to those dairymen who do not have silos as they add a needed suc- 

 culence to a ration that is ordinarily too dry. A porus soil that is well 

 manured and free from weeds will produce the best crop at the least 

 labor expense. Directions for making a trial of mangels based on the 

 variety and cultural trials at the college will be furnished. The farmer 

 to report his yield and success with them. 



G. F. Warren and P. J. White. 



No. loi. Alfalfa. — A test of different soil treatments and methods 

 of seeding in order to determine if alfalfa can be grown on the experi- 

 menter's farm and to determine how best to grow it. Full directions 

 for making such a test, based on knowledge obtained from previous 

 experiments will be furnished by the College, the experimenter to report 

 the results from each treatment. 



No. 106. Hairy Vetch. — A test of the value of rye or wheat and 

 winter vetch as a soiling crop for early summer feeding or as a cover 

 crop to be plowed under for soil improvement. Hairy vetch is a promis- 

 ing legume for either of these purposes. 



No. 108. Red Clover. — For farms that once grew clover but now 

 fail to do so. A test of different soil treatments in order to determine if 

 possible, what method will succeed in producing clover, also an examina- 

 tion of specimens for diseases or insects. 



No. no. Renewal of pastures and meadozvs without plowing. — 

 Usually the best way to renew grass land is to farm it a year or more and
