POTATOES 

 (Chapter 19) 



1. Bring some sprouting potatoes to school and place 

 them in a warm, moist place. Observe the sprouting of 

 the eyes. 



2. Cut a potato in about one-half as many pieces as 

 it has eyes. Plant these in a box of earth or in the ground 

 and pull up a plant every few days to observe the growth 

 of roots and tubers. How long after planting do the 

 young tubers start? 



3. If it takes 200 gallons of Bordeaux mixture, cost- 

 ing $1.50, to spray one acre of potatoes once, and it 

 takes two applications to cure the blight, what is the 

 cost of the mixture for spraying 10 acres of potatoes for 

 the season? 



4. How many bushels of potatoes worth 60 cents a 

 bushel will be needed to pay the extra cost of spraying? 



5. If an acre of potatoes yields 110 bushels, what is 

 the value of the crop at 40 cents per bushel? 



6. If a potato farmer gave his crop careful attention 

 it would cost him $25.00 per acre to grow potatoes. What 

 is the net profit per acre if the yield is 110 bushels worth 

 40 cents a bushel ? 



7. Potatoes are usually planted in rows 3 feet apart 

 with hills 16 inches apart in the row. How many square 

 feet of ground does each hill occupy? How many hills 

 will there be in an acre containing 43,560 square feet?
