MAINE AGRICUI.TURAL EXPERIMENT STATION. I913. 33 



Selected Turkey Red produced 27 1-2 bushels of grain and 

 2,385 lbs. of straw per acre. 



Considering these yields of grain in pounds per acre it is 

 seen that 30 1-2 bushels of wheat are equivalent in pounds to 

 a yield of 57 bushels of oats per acre; 27 1-2 bushels of wheat 

 to 51 1-2 bushels of oats. It should be said that more experi- 

 ments should be conducted to determine the time of planting in 

 its relation to yield of grain and straw. However, in our judg- 

 ment the time of sowing winter wheat should not be later than 

 September 5 to get the best results. 



Yield of Apples from Individual Trees. 



It has been felt for some time that in one respect the records 

 of the individual apple trees at Highmoor were not complete. 

 The yield of apples from each tree has in the past been esti- 

 mated and not accurately determined. Since in different years 

 such estimates are made by various people they are not suitable 

 for comparative purposes. After all it is the yield of apples 

 that is the important thing to know about a tree. This fact 

 was fully appreciated at the beginning of the experiments. The 

 reason for not attempting to measure the yield has been that it 

 was thought likely to involve too great a loss of labor at a verj- 

 busy season. With a good crop of apples there are twenty to 

 twenty-five pickers employed at Highmoor. If each man should 

 lose five minutes on each bag of apples it would mean a great 

 loss of time for the season. 



However, the necessity of having some accurate' measure of 

 the yield of fruit from each tree has been becoming more 

 urgent each year. It was decided that this year we should try 

 out some methods for doing this. With a relatively light crop 

 of apples this year it was possible to work out the details with- 

 out causing much loss of time. 



The method finally adopted was as follows : Large tripods 

 were constructed with the legs about twelve feet long. From 

 the center of such a tripod there was suspended a rod upon 

 which a pair of 60-pound spring balances hung. Such a tripod 

 was placed between the rows of trees to be picked. The pick- 

 ers all use bags which fasten over the shoulder. Each picker 

 brought his bag of apples to the tripod, hung it on the scales
