bushels, or an average of 4 bushels per tree on the cultivated 

 trees, as compared with 31 bushels, or an average of 2.8 bushels 

 per tree where mulching was used. 



By reference to the diagram of the orchard, page 183, it may 

 be seen that much better returns have, as a rule, been obtained 

 from those trees upon which stable manure has been used. For 

 example, trees 13, 14, 17, 18, 21 and 22, on the cultivated plat, 

 received stable manure and produced an average of 2.7 bushels 

 per tree in 1904, and 4.9 bushels in 1905; while the others, 

 receiving commercial fertilizers, gave an average of .8 and 3.4 

 bushels for the two years respectively. On the mulched area 

 similar results followed. Trees 55, 56, 59, 60, 63 and 64, 

 received stable manure and gave an average of 2 . i and 3 . i 

 bushels for the two years ; while the other trees, receiving com- 

 mercial fertilizer, yielded an average of i .9 and 2.5 for the two 

 years. These facts are given without further comment. 

 Future management of the orchard will of course be governed 

 by the lessons learned. 



Thu Potash Orchard. 



The study of the specific influence of different potash salts 

 upon the apple is continued as in former years. The treatment 

 is as detailed in Bulletin 89 ; but the need of additional nitrogen 

 being evidenced by the growth of the trees, an application of 

 350 pounds per acre of nitrate of soda, and of about 650 pounds 

 per acre of acid phosphate was made in 1904, besides the usual 

 excessive application of potash salts. The season being very 

 dry, the trees did not profit much by this application and it was 

 repeated in 1905, with marked advantage. 



The severe winter of 1904-5 worked serious injury to some of 

 the trees but as a result of the fertilizing and the cultivation 

 given, most of them have started a vigorous new growth, and 

 fruit buds are well developed for next year. 



Without going into details at this time, it may be said that 

 there is no noticeable difference in the character of fruit or of 

 the behaviour of the trees as a result of the form of potash used. 

 The work will be continued further, however. 



Orchard Rijnovation. 

 In 1902, because of the manifestly favorable results following 

 the treatment given the orchards above referred to, one hundred
