II. EXPERIMENTS WITH FERTILIZERS ON CEI.ERY. 



Upon the 26th of June, 1896, an experiment in fertilizing 

 celery was laid out near Rome, New York, upon the premises of 

 B. F. Richardson. The area was flat muck land, of half-wild 

 meadow, broken up that year. It had never grown celery and 

 had never received fertilizers. 



The rows of celery were 28 rods long and 4 feet apart. Each 

 row, therefore, represents about one-twenty-fourth of an acre of 

 land. The plants of Golden Self-Blanching were set from four 

 to six inches apart in the row, and the other varieties from six to 

 eight inches. The fertilizer was carefully strewn by hand in a 

 little furrow made upon either side of the row, after the plants 

 were established in the soil, and it was then covered with earth. 

 Care was exercised to keep the material from coming nearer than 

 two or three inches to the plants. The season turned out to be 

 very dry, and therefore the crop was less than it should have 

 been. However, it was given excellent care, and there were 

 marked differences in the plots when final notes were taken on the 

 3 ist of October. The celery was bleached by banking with earth. 



The samples shown in the illustrations were taken by selecting 

 six average plants from near the end of each row. The weights 

 of these six average plants are entered in the records below. 

 Chemical analyses were made from these samples, as displayed 

 on page 229. The photographs showing the samples are all taken 

 to the same scale. The weights of all the plants in each plot 

 were also taken, but are not reported here. 



VIII. Seven rows Golden Self-Blanching celery, set June 20. 

 Received July 17, 100 lbs., high-grade sulfate of potash, 14 

 lbs. to the row. 



Crop rather poor. Fig. 61. 

 Six plants, 4 lbs. , i oz. 



IX. Seven rows Golden Self-Blanching, set June 20. Received 

 July 17, 100 lbs., high-grade muriate of potash. 



Crop very much better than in plot VIII., the stalks being much 

 thicker, broader and stronger. The difference was such as to 

 impress any observer. Figs. 61, 63. 



Six plants, 5 lbs., 14 ozs.
