conducted. The per cent of trees giving strong, medium and weak growth during the 

 season, an average for all the varieties, is also given. 



It will be seen that there is an apparent injury from using large quantities mixed 

 into the soil in that the growth on these plots was not as strong as that on the plots 

 not so treated. It will be noticed also that where large quantities were spread on the 

 .surface and worked in shallow the growth was better than when it was mixed with 

 the soil at planting time. It would appear that moderate applications may be used 

 to some advantage. These trees will not be fertilized next spring and notes will be 

 taken as to their growth next season.

EXPERIMENTAL ORCHARD WORK. 



There are no bearing apple trees at this Station except a few scattered, uneven 

 ones along the base of the hills on land very broken and difEcidt to get at, consequently 

 it has been found advisable to select one orchard at Berwick, Kings county, one at 

 Bridgetown, Annapolis county, and one at Falmouth, Hants county, for orchard experi- 

 mental work. Spraying experiments for the purpose of getting definite information 

 as to what spray mixture will control the apple scab best and give the largest percent- 

 age of first-grade fruit have, for the most part, occupied our attention during the past 

 season. The experiments were duplicated as far as possible in the different orchards. 

 Orchards with trees as uniform as possible were selected, and these were divided into 

 plots of six trees each. All trees in a comparative test were given similar treatment 

 other than spraying, thus eliminating possible error. 



The experimental work .at Berwick and Falmouth, was conducted by J. M. Rob- 

 inson, B.S.A., Assistant for Horticulture, Experimental Station, Kentville, and at 



16 — 39 Kentville.
