200 Appendix. 



The Canada peas were as unsatisfactory as those mentioned above. 



Hairy vetch 20 pounds and coicpeas 45 pounds per acre. — On one-half of 

 the plot the vetch did exceedingly well ; it liad made a growth of IS inches 

 by the last of September and one month later a growth of 2 feet or more. 

 This was a good mulch for winter protection to the soil. The spring growth 

 was from 4 to 12 inches April 6. This rapid development continued to a length 

 of 3 to 31/, feet May 18, making a green live mat of from 12 to 20 inches thick. 



The cowpeas were very scattering and small and added nothing of conse- 

 quence to the crop. 



Hairy retell 40 pounds per acre. — The stand was good except in a few places 

 where it was scattering. The plants made their naturally slow growth at 

 first, but later on improved rapidly. The crop on this plot was not quite 

 as good as the vetch with cowpeas on the adjoining plot until the period of 

 blooming came on when they seemed to be equally good. At this time, May 18, 

 there was a heavy mat of vegetation 12 to 20 inches thicK, and when straight- 

 ened out the growth was from 3 to 31^ feet long. The photograph of these 

 two plots taken May 21 (see Plate I, B), shows the matted growth to be 2 feet 

 thick where the measuring rod stands. Such a vast amount of material plowed 

 under is of immense value to any of the Delaware soils. A portion of these 

 plots will be saved for seed. 



Cowpeas, Whippuriiill variety, 00 pounds per acre. — The seed did not ger- 

 minate well and one-half of the plot was a failure from the start. The other 

 half had a fair stand of moderate growth, being 8 to 12 inches high the last of 

 iSeptember. On October 22 they were killed by frost so did not amount to 

 much as a cover crop this year. Last year they gave ten times better results 

 than they gave this year. The dead plants were too few to form any winter 

 protection to the ground. 



Soy hcan On pounds per acre. — The stand of soy beans was much better than 

 thai of cowpeas, but was not what it should have been. Last year the soy 

 beans were four times as good as they were this year. At the end of September 

 the plants were from 8 to 12 inches high and made very little growth after that. 

 One month later they were badly injured by frost. This short growth made 

 scarcely any winter cover for the soil 



Soy heuns 4."i pounds and Canada peas 1 bushel per acre. — The soy l)eans 

 gave a better stand in this plot than in the one just mentioned. The growth 

 was about the same, 1 foot, which was not half of wnat it should have been. 

 It is very probable that had the soy beans and cowpeas been sown net later 

 than July 22, as they were the year before, they might have done better. Tliree 

 weeks of that warm weather would have benefited them materially. 



The Canada pe.is were very poor and a failure. 



Crimson chirer l."i pounds per acre. — The hard surface crust prevented a 

 free germination, so the catch was rather poor although the growth was good. 

 It came through the winter in good condition and grew well in the spring, but 

 w:is somewhat bunched and uneven. It was S to 10 inches high April 22. 

 The plot improved rapidly and by Slay 18 there v.'as a heavy crop 1 to 2 feet 

 high and in full bloom. I'late 5, C. shows this crop May 21. tl was cut 

 May 22 and yielded at the rate of 18,744 pounds of green tops per acre. This is 

 ,1 little heavier than the yield of tops of the rye and vetch together. 



Crimson clover 7 pounds and Canada peas 1 bushel per acre. — The clover 

 ■was very scattering, due to poor germination ; the growtn was fairly good. The 

 peas were very poor also. This was not a success. 



Crimson clover ~\(, pounds and cowhorn turnips (> ounces per acre. — The 

 clover was like that with Canada peas above. The turnips gave a poor catch, 

 except in patches, but the plants were good ; some were lo inches high the last 

 of October. A dry surface crust which formed in consequence of a heavy 

 vain immediately after seeding, was no doubt the cause of such poor germi- 

 nation of the see., and the failure of the crop. 



Red clover and mamninth clover. — There was a plot of each of these seeded
