ORCHARD NOTES. 43 



Treatment ipio. All six plots were pruned according to the 

 need of each tree and all except A were thoroughly sprayed 

 three times during the season with bordeaux mixture and lead 

 arsenate. Plot A was treated with lime-sulphur and bordeaux 

 according to the experiments described in the publications 

 referred to. 



Plots A and F received an application of chemical fertilizer 

 of 3.3-10-7 formula at the rate of 1500 lbs. per acre. Plot E 

 received 6 cords of barnyard manure. No fertilizer was applied 

 to Plots B, C and D during this season. B and C were fenced 

 and 5 sheep and 5 brood sows were turned into the respective 

 plots about the first of May. Sod was broken in A, E and F 

 about the last week in April, and cultivation was continued 

 throughout the season up to August i. Then winter vetch 

 was sown in these three plots as a cover crop. The animals in 

 the two plots were removed at the close of harvest. 



Treatment ipii. Treatment was identical with that of the 

 preceding year, except that all plots, with the omission of E, 

 received 1000 lbs. of chemical fertilizer of 4-8-7 composition. 

 Lime-sulphur and lead arsenate were the spray materials used. 



General Notes. Comparative and specific data are given in 

 tables to follow. In general the results so far obtained seem 

 to indicate most strikingly that the chief factor accountable for 

 low production per tree is the lack of cultivation. 



It must be remembered that in 1909 the condition of all the 

 trees in this entire experimental orchard, even making due al- 

 lowance for the few cases of difference in size and age, was 

 not uniform. However, the trees showed no greater differences 

 in vigor or lack thereof, than would be observed in any block 

 of trees planted presumably at one time, and having experienced 

 the same treatment or neglect for an indefinite period ; and this, 

 of course, holds true for their condition in the spring of 1910. 



By the close of the season, however, the difference in amount 

 and color of foliage between the cultivated and the uncultivated 

 divisions was significant. The yield of fruit, although com- 

 paratively small for the entire orchard, showed notable plot 

 differences, whereveiwthe size of trees allowed a fair basis of 

 comparison. 



The foliage in Plots B, C and D withstood the dry summer 

 of 1910 poorly. Disregarding the early leaf yellowing, for which 

 bordeaux spray injury may have been accountable, the leaves
