HATCH EXPERIMENT STATION. 



[Jan. 



crinkling effect "wliicli has been alluded to. As the season 

 advances, the soy bean plants as a rule show a more normal 

 leaf development ; and, although the crinkling this season 

 was excessive, the yield on the nitrate of soda plots does not 

 appear to have been materially decreased, as a consequence. 



Attention is here called, with regret, to the fact that there 

 was undoubtedly an error made in determining the weight 

 of the straw on Plot 10. Close observation throughout the 

 season leads to the conclusion on the part both of my assist- 

 ant and myself that the relative growth of vines as compared 

 with seed on this plot was quite as large as on any other in 

 the field, and yet the weight as reported shoAvs it to have 

 been in proportion to seed less than on any other plot. 



The yields obtained on the several plots and the sources 

 of nitrogen on each are shown in the following table : — 



Yield of Soy Beans per Acre. 



It will be noticed that the crop, even on the best plot, this 

 year is small. In IDOl, when the same crop was grown, the 

 yield on the poorest plot was at a higher rate (25.86 bushels 

 of seed) than that on the best plot this year ; while the aver- 

 age yield on all i)lots, including those to which no nitrogen 

 was applied, was at the rate of 29.9 bushels per acre in 

 1 901 . Th(- inferiority of the crop of this year was undoubt- 

 edly largely the consequence of the unfavorable season, al- 

 though there is some evidence that this soil may once more
