The following examples will Illustrate the difference between the two. A 

 50-cent retail price is used in these examples, rather than the prevailing A9c 

 price merely to simplify the arithmetic. Fractions are rounded to the nearest 

 cent. 



a) A store margin of 257„ on a 50c: item at retail is 13c - price to grower 37c. 



A mark-up of 33% on this wholesale price of 37c would result in a retail 

 price of A9c • 



b) A store margin of 33% on a 50c item is 17c - price to grower 33c. A mark-up 



of 50% on this wholesale price would result in a retail price of 50c. 



c) A store margin of 40% on a 50c item is 20c - price to grower 30c. A mark-up 



of 66% on this wholesale price would result in a retail price of 50c. 



d) A store margin of 50% on a 50c item is 25c - price to grower 25c. A mark-up 



of 100% on this wholesale price would result in a retail price of 50c.

SIZE AND YIELD OF McINTOSH APPLE TREES 

 ON E.M. II AND VII ROOTSTOCKS 



The branch spread of 19 year old Mcintosh trees on E.M. II and VII rootstocks 

 was determined by taking two measurements at right angles to each other. Measure- 

 ments were made from the tip of the outermost branch on one side of the tree to the 

 outermost tip on the opposite side. The average spread of trees on E.M. II was 

 25 feet. The smallest tree had a spread of 20 feet and the largest tree had a 

 spread of 28 feet. Trees on E.M. VII were a little larger and more uniform in size. 

 The average spread was 29 feet with a range of 27 to 31 feet. No attempt has been 

 made to confine the spread of these trees by pruning. Some heading back has been 

 done in the tops of the trees to restrict tree height. The height of the trees 

 ranges from 12 to 14 feet. 



The average annual yield per acre during the past 19 years for trees on E.M. II 

 was 547 boxes per acre, and 619 boxes for E.'M. VII trees. These yields were 

 calculated on the basis of a 20 ft. x 30 ft. planting distance for permanent trees. 

 Trees on seedling rootstocks planted 30 ft. x 40 ft. would have to have average 

 yields of 15 and 17 boxes per tree to equal the yields of trees on E.M. II and VII. 



The average yield in 1962 for E.M. II was 1447 boxes per acre and for E.M. VII 

 1483 boxes per acre.
