Notes upon Celery. 225 



Crop poor, the stalks being stocky but very sort. Fig. 67. 

 Six plants, 2 lbs. 14 ozs. 



XIX. Two rows Golden Self- Blanching, set July 8. No 

 fertilizer. 



Crop worthless. Fig. 67. 

 Six plants, i lb. 8 ozs. 



XX. Seven rows Golden Self- Blanching, set July 21. Received 

 July 28, 25 lbs. nitrate of soda, 75 lbs. dissolved South Caro- 

 lina rock, 100 lbs. sulfate of potash. 



Crop fair. Fig. 67. 

 Six plants, 4 lbs. 6 ozs. 

 KXI. Two rows Golden Self-Blanching, set July 21. No 

 fertilizer. 

 Crop worthless. 

 XXII. Seven rows Golden Self-Blanching, set July 22. 

 Received July 28, 50 lbs. nitrate of soda, 100 lbs. dissolved 

 South Carolina rock, 200 lbs. sulfate of potash. 

 Crop late because of late setting, but Mr. Richardson regarded 

 it as the best lot on the plantation considering the chance it had. 



All these records show that wood-ashes gave the best results, 

 although a combination of nitrate of soda. South Carolina rock 

 and sulfate of potash (plot XXII.) promises to do well. Muriate 

 of potash excelled the sulfate. Nitrate of soda alone gave poor 

 returns. The check (no fertilizer) plots were not worth the 

 growing. 



It should be said that although this test was made with much 

 pains, no generalizations should be drawn from it. The subject 

 needs to be studied a number of years and in more detail before 

 definite conclusions can be drawn. This paper is meant as a 

 report of progress, and to call the attention of those who are 

 experimenting with celery fertilizers to our desire to obtain more 

 specific information. We shall endeavor to make similar experi- 

 ments the coming season. It will be observed, however, that the 

 results upon these plots were as emphatic as could have been 

 wished. 



The chemist was asked to help interpret the results, and his 

 analyses of a plant from each plot, and of the soil, are given below.
