PLANTS WHICH CAN NOT BE RECOMMENDED. 



The following gra.s.sos and forage i)laiit.s have l)ceii tested, but the 

 results arc not such tluit they can be reconimcnded for Nebraska. 

 Some of the trials were failures hccause the seed did not germinate. 

 In such eases judgment upon the value of these plants must l)e reserved. 

 The experiments were based upon trials extending, in many cases, 

 over as many as six years: 



At/ri>jH/r<»i ernu'/n/ni. The tests with this wheat-grass were unsatis- 

 factory on account of a njixture of seed, l)ut it showed no evidence of 



value. 



Agropynm d'iver(/em. — There was no shmd produced with this grass, 

 but experiments at other stations in the Northw^cst, notably at Pull- 

 nian. ^^'asll.. have shown that it can be grown successfully from the 

 seed and is well adapted to the semiarid conditions of that region. 

 Although with seed of good vitality it may prove successful here, it 

 probably has no advantage over A(/r(>jn/r>>n occl dental c A<i>'0]>yron

 not promising.

JoJmson grass {Andropoijim halepemis). — A common and valuable 

 hay grass for the Southern States, but it has shown itself to be a diffi- 

 cult i)lant to eradicate, and hence has T)ecome in many sections a great 

 pest. In Nebraska it will not usually survive the winter. This grass 

 was sown at the station in the spring of 1897 and survived the winter 

 of 1897-9.S, but it was killed out during the next winter. Other 

 atteiupts to raise it resulted in continual loss during the winter. 



Sineet vernal grass {Antlivxantlmni odoratum). — This grass has little 

 forage value anywhere, but it is sometimes used in the Eastern States 

 to impart a pleasing odor to the hay, for which purpose a small 

 quantity suffices. 



Australian salthmh {Atriplex semiljaccata).— Thin forage plant has 

 proved quite successful in California and in some other parts of the 

 Southwest, especially in alkali soil. However, in States as far north 

 as Nebraska it is unable to survive the winters, and hence must be 

 grown as an annual, but the uncertainty of germination and the rather 

 meager growth the first season render it unsatisfactory as an annual 

 forage plant. The trial at the station extended over four years, but 

 in no case were the results at all promising. The plants were killed 

 out every winter except in 1900-1901. Even the second year's growth 

 • was too small to be of much value. 



Swamp-chess {Bronms ciUatus).— The plots gave a fairly good stand, 

 but the plants do not thicken up in the plot, and the individuals are 

 coarse and not leafy enough for hay. Although this grass might be
