CORN 115 



lected from the detasseled rows. This gives pedigreed corn, 

 because the parentage is known on both sides. The yield 

 of corn may be increased several bushels to the acre by 

 using seed selected and bred by this method. 



2. Acre Yield. Select an acre of good corn land. 

 Fertilize it and prepare it well. Pick out the best seed 

 corn, about 15 ears, and test them for germination, so that 

 the seed selected is sure to grow well. Plant 4 kernels in a 

 hill and thin to three plants when well up. Give it the 

 best care during the summer. In the fall, husk the corn 

 and weigh it, allowing 70 pounds of ears to a bushel. 

 Compare this yield with the average yield of the rest of the 

 field. 



3. Determining Stand of Corn in a Field. Select 10 

 rows in different places across the field. Count the number 

 of hills in each row if all had been planted. Next count 

 the number of hills with number of stalks, the number of 

 hills with i stalk, the hills with 2 stalks, and the hills with 

 3 stalks. Count those with more than 3 stalks with those 

 with 3 stalks. Estimate how many stalks all the 10 rows 

 would have if every hill had 3 stalks. Find how many 

 stalks were lacking, that is, how many stalks there are on 

 the basis above given. If the 10 rows had a total of 3,600 

 hills, in a perfect stand, or 100 per cent, there would be 

 10,800 stalks in them.
