FERTILIZERS FOR TOMATOES. 57 



Some of the horticultural statistics of these results are 

 as follows : 



" I. The highest average weight per fruit of the Ignotum 

 variety was on plot 6, of the Acme on plot 7, and of the 

 Dwarf Champion on plot 8. 



"2. The tendency to bear double flowers, which pro- 

 duced irregular-shaped fruit, seemed to bear no relation to 

 the quantity of nitrogen applied, nor to the variety. The 

 same plant produced both single and double blossoms. 



"3. The number of perfect fruits was absolutely larger 

 on the plots receiving most nitrogen, but there was no very 

 marked relative increase in number. 



"4. Comparison of the three varieties shows that Acme 

 gave the largest yield in artificial soil, but the yield of Igno- 

 tum was considerably the largest of the three when grown 

 in rich garden soil. 



"Acme gave the greatest average number of tomatoes 

 per plant, while the average weight per fruit of Ignotum was 

 considerably greater than that of the other varieties. 



"5. The Dwarf Champion proved to be an unprofitable 

 variety in this test. 



"6. Tomatoes from the unfertilized plot (Plot 4) were 

 small, smooth, and of good shape, but the color was not 

 normal. They were too light in color and slightly rusty- 

 looking, having a faded appearance. The flesh of the 

 tomato was very dry, and sweet to the taste much sweeter 

 than tomatoes from other plots. 



' ' Tomatoes of best form, size and color grew upon plots 

 6 and 7. Those from plot 8 (and a few from plot 7) ripened 

 very unevenly, and were green about the stem when the 

 other side of the fruit was of good color and apparently 

 ripe. These tomatoes had a decided tendency towards soft- 

 ness while still green ; the form and size were very good. ' ' 



We come now to a comparison of plants grown in natural 

 soil with those grown in artificial soil. " These were set 

 much closer in the bench than those grown in artificial soil. 

 The latter had a bench space of 2.31 square feet per plant, the
