. Field crop production; a text-book for elementary courses in schools and brief courses in colleges. Agriculture. 42 FIELD CROP PRODUCTION different types we find variations in the shape of the kernel and the manner of growth of the plant. 34. Dent corn. — Dent corns have the hard or horny endosperm arranged along the sides of the kernel and the white or soft endosperm sm^rounding the germ on three sides and extending to the crown. Thus the horny endo- sperm forms rigid sides to the kernel, while the center, being composed of soft endosperm containing a large amomit of water, shrinks more rapidly than the sides and causes a dent in the crown at maturity. Because of this dent in the crown, the class is called dent corn. The degree of the dent is largely due to the proportion of soft to hard endosperm. Dent corn is char- acterized by its deep and usually wedged shaped grains, large di- ameter of the ear and large num- ber of rows of kernels. There is of course great variation in the height of the plant, the size and shape of the ear, and the hke, due to variety differences or to environment. Usually only one ear is produced on each stalk, but when planted thinly or on very fertile land, two and sometimes three ears are produced. Dent corn does not sucker freely except when thinly planted. The number of rows of kernels per ear varies from 10 to 24, but almost all of the dent varieties have from 16 to 20 rows. The ears vary from 6 to 14 inches in length, and from to inches in circumference. The most common measurements are from to 7 inches in cir- cumference and from 8 to 9 inches in length. Ears vary.
