PREFACE 



Agronomy. The farm crops of a country are the foundation 

 of its agriculture. All farm boys and others interested in agri- 

 culture should make a careful study of these crops. The Field 

 Crops Section of PLANT PRODUCTION is designed for those who 

 desire a plain practical treatise on the various field crops. Only 

 the more important economic plants have been discussed. The 

 aim of the authors has been to present the subject matter in 

 such simplified form that there will be no doubt as to its mean- 

 ing in the mind of the reader. The various home projects 

 presented will enable the student to put what he has learned into 

 actual practice. 



The simple truth concerning the growth of farm crops, im- 

 pressed upon the student as nature unfolds to him her secrets, 

 should develop interest in agriculture and a better understand- 

 ing of the many interesting facts of science continually unfolded 

 before our eyes in the everyday world in which we live. 



After many years of teaching experience with young people 

 from the farms, the authors have endeavored to put into book 

 form the methods which proved most successful in impressing 

 young people with the value and importance of pure-bred seeds 

 and the best practice in the growing and handling of farm crops. 



Horticulture. The text in horticulture aims to present 

 in a simple, direct, and logical manner the basic principles gov-

 problems, and exercises on the text as might be used for class 

 work.

 tion of the individual plant as a unit, is most adaptable to peda-
