more decided improvement in the crop, that is, the stalks, 

 were mucii larger, were taking on fruit more rapidly and 

 presented a richer color than the plots not fertilized after 

 planting. By noticing the difference in the yield of plots 

 having the same quantity of fertilizers, it appears that a 

 given amount used interculturally at an earlier stage of crop 

 growth, gave better results than the same quantity, one-half 

 applied at the earlier stage and the other half several weeks 

 later. For instance, by comparing plot No. 1 with plot No. 7^ 

 it is shown that a better yield resulted from the single ap- 

 plication to plot 7 in June than from the two applications to 

 plot 1 in June and July. 



Also in comparing No. 2 with No. 8, it is seen that a better 

 yield was secured from the June application on No. 8, than 

 from the June and July appiications on No. 2. 



By a still further comparison of plots 4 and 9, the same 

 fact is established, that a single application of nitrate soda 

 in June on plot 9, gave a better yield than the same quantity 

 of nitrate soda at different times on plot No. 4, The 100 

 lbs. applied at once to No. 9 acted more efficiently than the 

 two applications to No. 4, and the inference is, that the most 

 favorable conditions existed as to No. 9, for a maximum 

 yield. 



Taking the average yield of the three unmanured plots, 

 which is 809^ lbs. seed cotton per acre, the difference in 

 favor of fertilizers is plainly seen by reference to the table 

 of results. 



The following table shows the results of this experiment :
