 and the test should be to get a regular number of kernels for each drop

Cross-sections of kernels showing depth of germ and the white floury or starchy- 

 portion lying just below the germ. The kernels in the lower row have better germs than 

 those in the upper row. Nos. 17. 15. 13 and 11 are among the best, while Nos. 2, 14 and 18 

 are among the poorest because they have very shallow germs and are low in feeding value. 

 The white, starchy appearing material lying just below the germ has the very lowest 

 feeding value of any part of the kernel. Nos. 17, 15 and 11 show a very small amount of 

 this material, while Nos. 1, 2, 12 and 19 show a great deal and should be discarded for 

 seedpurposes. 



The upper row (Nos 21-37) show the depth of the germ when the kernels are split 

 into lengthwise through the middle of the germ. Nos. 21, 24, 27, 28, 29, 33 and 35 show 

 very deep germs and are from ears rich in protein and oil. No. 35 being from the ear 

 richest in protein of 2,000 tests, while Nos. 22, 23, 36 and 37 are from ears very poor in 

 feeding value it will also be noticed that the germs are very small. 



Note. — Chemical analysis shows that the per cent of ail and protein is 

 higher in the germ than in any other part of the kernel. Thus we can 

 see the importance of a deep kernel and a broad, deep, well filled germ. 



of the planter. If the corn is uniform the planter should give the desired 

 number of kernels at each drop. If the number of kernels dropped is ir- 

 regular this corn should be resorted to remove irregular or discarded 

 kernels. 



There is no one thing that would do more to increase the yield of 

 corn on every farm, in Iowa than the careful selecting and sorting of the 

 seed both in the ear and after it is shelled, and then stay with it until 

 the planter will drop the desired number of kernels at least ninety times 

 out of 100 tests. It may be necessary to have the plates of the planter 

 drilled or get new ones or take more care in sorting out the large, small 

 and irregular kernels. The main thing is to stay with it until the work Is 

 satisfactory. 



The preparation of the seed corn and testing of the planter should be 

 done during the latter part of February and the forepart of March. If 

 this important work is put off until April or May it is very likely 

 neglected, as is too often the case. This is simply a matter of good busi- 

 ness management and no one can afford to neglect it. 



After the corn has been sorted, shelled and thoroughly tested in the 

 planter it should be put in sacks (about a bushel in each sack) and hung
