Prior to 1910, the average corn yield was below 28 bushels an acre, and no state averaged over 54. However, with more than 100 bushels per acre having been produced in practically every section of the United States, yields can be doubled and the author believes that doubling our acre yield of corn is so important that it should be the focus of corn clubs, associations, breeders, and growers. This book is a collaborative effort between the author and the US Department of Agriculture and the States Relations Service. It provides the necessary scientific knowledge and practical methods to achieve these goals, and includes illustrations of 52 lantern slides used by the author to educate farmers and extension lecturers on the subject.
