Excerpt from Vegetable Crops

In the preparation of this book the author has had one main purpose; namely to meet the needs of college and university teachers of vegetable gardening for a textbook which brings together the results of experimental and research work. While vegetable gardening has been given less attention by scientific workers than most other important branches of agriculture, there is a large amount of experimental evidence available that has never been brought together. This material has not been used by vegetable gardening teachers to the extent that it should, largely because it is so scattered through the literature of the past forty years. The author has studied the literature and has attempted to give the experimental evidence available on the subjects discussed. On many subjects discussed no experimental evidence was found, and in these cases, the author has given what he believes to be the best information available.

The author believes that college and university teaching should be based mainly on principles of growing and handling vegetables rather than on detailed directions for performing the various operations. The emphasis should be on the science rather than on the art of gardening. Proficiency in the art of gardening can be acquired only by practice, and it is impracticable for the college to give the student sufficient practice in all phases of gardening to make him proficient. It is entirely practicable to teach students principles upon which successful gardening practice may be based and this is the contribution that the college should make. It is clearly recognized that some practice is necessary to a thorough understanding of the principles involved. The socalled practical exercises or laboratory work should be so planned and conducted as to bring out the principles taught, rather than merely to teach the student how to perform a given piece of work. The author has attempted to outline the best practice and to back this up with experimental evidence where such evidence is available.

In the preparation of this book extensive use was made of the material presented in publications of the various state experiment stations and the United States Department of Agriculture, and in scientific journals. Credit has been given for the material used. The author wishes to express his appreciation for helpful suggestions from his colleagues and others, especially to Dr. Paul Work, Dr. E.V. Hardenburg, and Professor H. W. Schneck.
