1 62 STORKS AGRICULTURAL EXPERIMENT STATION. 



The yield from the different pots in the same group was 

 fairly uniform, but the averages of the yields for the different 

 groups varied considerably. Unlike the experiment with Hun- 

 garian gra.ss, the yields of millet increased with the increase in 

 nitrogen as fertilizer. This may be due to the larger growth 

 made by the millet and consequently to the greater require- 

 ments of the crop for nitrogen. There was a fairly constant 

 increase of nitrogen and of protein in the millet crop of the 

 different groups, corresponding to the amounts of nitrogen 

 used in the fertilizer, but this was less noticeable in the case of 

 the Hungarian grass. These results would seem to indicate 

 that in cases where the nitrogen is largely used in producing 

 growth it does not increase the proportion of nitrogen to such 

 an extent as where less is required for the growth of the crop; 

 and in order to increase more largely the proportion of nitrogen 

 in the crop it may be necessary to use nitrogen in amounts be- 

 yond the needs of the crop for growth. 



EXPERIMENT WITH SOY BEANS. 



The experiment with soy beans comprised pots Nos. 49 to 

 64 inclusive. It was similar to the experiments of the two 

 years preceding with the same crop except that smaller quan- 

 tities of nitrogen were used in the fertilizer. The medium 

 earl}^ green variety of soy bean was grown. The plants were 

 thinned out when about an inch high, only six being left in 

 each pot. The growth seemed to be normal throughout the 

 season and the appearance of the crops in the different pots 

 was mtich the same. The results of the experiment are given 

 in Table 80. 



The average yield was but very little larger where the 

 largest quantities of nitrogen were used than that where no 

 nitrogen was used. As in similar experiments in 1S99 and 

 1900 there seemed to be no relation between the quantities of 

 nitrogen used and the percentage of nitrogen and of protein in 

 the crop. In fact in the experiment for 1901 the percentage 

 of nitrogen decreased slightly as the amount of nitrogen used 

 for the different groups was increased. Attention is called to 

 this not because the decrease in the percentage of nitrogen had 

 an}? marked significance, because it was slight, but rather to 

 point out that with soy beans there seems to be no relation
