June twenty-first, plots 1, 2 and 3 were set to Zimmer Spanish 

 tobacco, setting five rows to each plot and forty plants to the ro\v. 



June twenty-fourth, plot 4 was set to Spanish Zimmer tobacco, 

 with plants like those set on the other plots. 



A commercial fertilizer containing nitrogen, phosphoric acid 

 and potash was applied to plots 2 and 3 on the following dates: 



July first, July fourteenth, August sixth. 



The potash applied to plot 4 was in the form of a high grade 

 sulphate (ninty per cent pure), while the potash applied to plot 3 

 was in the form of a chloride (muriate) eighty per cent pure. 



Four and eight-tenths pounds of i>otash, 3.16 pounds nitrogen, 

 and 3.20 pounds of phosphoric acid was applied to each of plots 

 2 and 3. The nitrogen was in the form of nitrate of soda, guaran- 

 teen ninety-six per cent pure. The phosphoric acid was in the 

 form of available fine rock phosphate. 



The fertilizers were sprinkled around the plants and hoed in. 

 Plot 4 received no fertilizer whatever, but received the same cul- 

 tivation as plots 1, 2 and 3. September seventeenth the tobacco 

 on all plots was cut and weighed, the weighing being done imme- 

 diately after cutting. 



The following plan of the plots will show the amount of ferti- 

 lizer applied to each plot and the weight of tobacco at the time 

 of cutting. This plan shows the relative location and size of the 

 plots, with the kind and amount of fertilizer applied, and also the 

 yield of tobacco: 



Plot 1. — Bam manure, 2,355 pounds; weight of tobacco, 517 

 pounds. 



Plot 2. — Sulphate of potash, ten pounds ; nitrate of soda, twenty 

 pounds; plain super phosphate, twenty pounds; weight of tobacco, 

 4.") 7 pounds. 



Plot 3. — Chloride of potash, ten pounds; nitrate of soda, twenty 

 poimds; plain super phosphate, twenty pounds; weight of tobacco, 

 442 pounds. 



Plot 4. — No fertilizer; weight of tobacco, 236 pounds. 



From the foregoing plan of the plots it will be observed that 

 the barn manure plot produced the moist tobacco, but if the ctx'^t 

 of the fertilizers of all the plots are taken into account it will be
