number was own-root stock and one- 

 half grafted. During the three sea- 

 :sons mentioned above, 95,013 roses 

 -were produced, an average of about 25 

 flowers per plant per season, which is 

 to be considered a satisfactory yield 

 for first year plants, a large number 

 •of which were injured in the course of 

 the experiment by overfeeding in the 

 •attempt to determine the maximum 

 amount of fertilizer that might safely 

 •be used. Of these 95,013 flowers, 46,135 

 were Killarneys and 49,878 Brides, 

 showing a larger production of Brides 

 under the conditions of the experi- 

 ment. Of the flowers produced by Kil- 

 larney, 21,297 were produced from 

 ■own-root stock and 23,838 from grafted, 

 •showing a larger production from 

 grafted stock. Of the Brides, similar- 

 ly, 23,019 were produced from own- 

 toot stock and 26,859 from grafted 

 Stock. Results indicate, then, that in 

 the order of production the plants 

 rank as follows; grafted Bride, 

 grafted Killarney, own-root Bride, own- 

 root Killarney. 



The average length of stem of the 

 own-root Killarneys was 10.6 inches; 

 of grafted Killarneys, 10.5 inches; of 

 own-root Brides, 14.6 inches; and of 

 grafted Brides, 14.9 inches. The qual- 

 ity of the flowers, measured in this 

 manner, is about the same in the Kil- 

 larneys, whether own-root or graftad, 

 and is somewhat superior in grafted 

 Brides to own-root Brides. The ques- 

 tion whether it pays to grow grafted 

 stock may be answered by the figures 

 given above, and the average price for 

 flowers of such quality. With grafted 

 Killarney, for instance, the excess pro- 

 duction over own-root stock of 960 

 plants was 2,541 flowers. The average 

 wholesale price of Killarneys of this 

 •quality would range around $6 per 

 100; the excess production of these 960 

 plants would sell for 1152.46 at this 

 price, — twice the difference in cost be- 

 tween own-root and grafted Killarney 

 per thousand. This, of course, is lor 

 the first year after planting, alone. 



Those sections to which manure 

 alone was applied are compared in the 

 figures given below for the average 

 number of flowers produced per 16 

 plants with those sections to which 

 eight pounds of dried blood, two 

 pounds of acid phosphate and two 

 pounds of potassium sulphate per 100 

 square feet, and with sections to which 

 32 pounds of dried blood with amounts

of acid phosphate and potassium sul- 

 phate as named in the sections pre- 

 vious had been applied. 



These figures show that 32 pounds 

 of dried blood per 100 square feet is 

 excessive for all the roses excepting 

 Killarney own-root. These plants have 

 a smaller root system than Killarney 

 grafted, and probably this is the rea- 

 son they produce more flowers with 

 heavy applications of dried blood in 

 contrast to the grafted stock. On the 

 whole, it is inadvisable to apply more 

 than eight pounds of dried blood per 

 100 square feet. On the other hand, 

 applications of acid phosphate up to 

 eight pounds per 100 square feet (the 

 largest amount used in the experi- 

 ment) gave increasingly larger num- 

 bers of flowers as the application was 

 increased, showing that the roses re- 

 sponded to applications of this fertil- 

 izer. No benefit was observed from ap- 

 plications of potassium sulphate, as 

 was the case with carnations also. 

 These results lead to the recommenda- 

 tion of commercial fertilizers in the 

 following amounts for first year roses: 



Fertilizer per 100 sq. ft. 



Dried blood 8 lbs. 



Acid phosphate 8 " 



Experiments are being carried on 

 with still heavier applications of acid 

 phosphate; when they are completed, 

 the advisability of heavy applications 

 of this fertilizer will be determined. 



Experiments have been made during 

 the year 1913-14 in regard to the use 

 of sulphate of ammonia in place of 

 dried blood on roses. It is found to be 

 a satisfactory source of plant food, 

 but much more difficult to use success- 

 fully, since roses are particularly sus- 

 ceptible to overfeeding with it. No ex- 

 periments have yet been made with 

 nitrate of soda. Acid phosphate was 

 used during the experiments as a 

 source of phosphorus. It is quite prob- 

 able that finely ground steamed bone 

 meal could have been used in equal 

 amounts with as good results, al- 

 though its value was not tested. The 

 dried blood should not be applied in 

 full amount at the time of preparation 

 of the soil, but one-fourth should be 

 mixed with the soil and manure at 

 this time, followed by three further 

 applications as top dressings during 

 the season, at times when the roses are 



coming into heavy crop. On no ac- 

 count should application be made dur- 

 ing the off season, or the period of lit- 

 tle growth, during the dark days of 

 winter. Care should be taken not to 

 scratch the dried blood into the soil 

 deeper than one-half inch, as deeper 

 cultivation will cause the breaking of 

 many small roots, and dropping of the 

 older leaves, as a result of the disturb- 

 ance of the root system. 



The results given in this summary 

 were obtained by applying fertilizer to 

 the type of soil known as the brown 

 silt loam, common throughout the 

 "corn belt." On account of the mod- 

 erate amount of dried blood recom- 

 mended, and the small tendency of 

 acid phosphate to produce injury from 

 overfeeding, these amounts are un- 

 doubtedly safe for use on any Illinois 

 soil. The fertilizers recommended will 

 supply the elements lacking in most 

 soils also, with the exception of those 

 peaty and sandy soils of northern Il- 

 linois which have been shown to be 

 deficient in potassium.
