Book Description
Excerpt from Sixth Annual Illinois Corn Performance Tests, 1939 Each test field was planted as described in Bulletin 427 On all but the Modoc field, each entry (variety or hybrid) was planted in 10 plots, each plot being 12 hills long and 2 rows wide. At Modoc 45 of the 57 entries were planted in 9 plots instead of 10. All plots were planted 3 kernels to a hill, and the only correction made for imperfect stand was to adjust the yields for missing hills. All seed was treated with organic mercury dust before planting. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from Illinois Corn Performance Tests, 1937 This shift to hybrid corn means that many farmers who formerly selected their seed from fields of open-pollinated corn on their own farms are now depending on purchased seed, and they are finding a large number of hybrids on the market from which to choose, many of which are good, some of which are definitely superior to the better open-pollinated varieties, and still others of which are no better than the open-pollinated varieties. The field tests reported herein have therefore been made in order to help the farmer to choose those strains of corn that have outstanding merit, and to help the producer in his efforts to develop such strains. They are a part of a corn-improvement program conducted in coopera tion with the Division of Cereal Creps and Diseases, Bureau of Plant Industry, U. S. Department of Agriculture, and the Illinois State Natural History Survey. The data for the three previous years of these tests are reported in Bulletins 411, 427, and 429 of this Station. For the first time in the history of the hybrid corn program. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from Illinois Corn Performance Tests, 1940 At Round Lake the moisture content of the samples ranged from percent to percent (table 4) on October 9. The average for the 5 adapted open-pollinated varieties was percent; and 14 hybrid entries had the same or a lower percentage Of moisture. The average for the entire field on October 9 was percent, and at harvest (november 15) it was percent. The average of the open-pollinated varieties at harvest time was percent; and 42 hybrid entries had the same or a lower percentage. The moisture content of the hybrids at harvest time ranged from percent to percent. The above data from the Round Lake field indicate that after an early killing frost most hybrids dry Out faster than the open-pollinated varieties. In general the hybrids which had the higher percentage Of moisture on October 9 had the higher percentage at harvest, and the hybrids with the lower percentage of moisture on October 9 had the least moisture when harvested. At Kings (table 6) the situation was much the same as at Round Lake. The moisture content of the grain decreased more rapidly in most of the hybrids than in the open-pollinated varieties. On Oc tober 8 the percentage of moisture for all entries on the field ranged from percent to percent, while at harvest time it ranged from percent to percent. Eleven hybrids had the same or a lower moisture content than the average of the open-pollinated varie ties on October 8; at harvest time 31 hybrids had the same or a lower percentage of moisture than the open-pollinated varieties. Dropped ears. A count was made of the dropped ears on all of the 1940 test fields, but there were too few such ears to warrant the drawing Of any conclusions.

Book Description
Excerpt from Illinois Corn Performance Tests: Results for 1936 The samples taken for determination of damaged corn were stored for a time in a heated dryer. The percentage of damaged kernels, by weight, was determined in either a 200 or a 250-gram sample of the grain, according to the Federal Grain Grade standards. The acre-yield of sound corn was computed from the total acre yield and the percentage of sound corn. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from Illinois Corn Performance Tests, 1941 Greenfield five open-pollinated varieties were grown and are separated from the hybrids in making up averages and resistance ratings. With each table is a footnote indicating the difference in the total lodging necessary for significance, and the table should be studied with this difference in mind. Tables 13, 17, 21, 24, and 29 Show that many widely used hybrids are below average in their resistance to lodging caused by rootworm attack. These data Show why so much corn was badly lodged in Illi nois during 1941. It should be kept in mind that the lodging reported in these tables is only that caused by rootworms.
