Foreword 



This PUBLICATION present? the 64th annual report of the Director 

 of the. Agricultural Experiment Station of the L niversity of New 

 Hampshire, and is a summary of the results on some eighty project? 

 for the period July 1. 1951. to June 30. 1952. The brief individual 

 project summaries were prepared by the respective project leaders. 

 The material presented herein is organized by departments and not 

 specifically by subject matter. 



The introduction of new projects and the termination of old 

 ones are constantly taking place. A special effort is made to serve 

 the agricultural interests of the state through both fundamental and 

 applied research. With the limited funds available it has not been 

 possible to respond to all requests for specific research or to meet 

 all the needs of agriculture. We try, however, to use all our resources 

 effectively and efficiently. 



Our research workers are informed about agricultural problem- 

 through their frequent contacts with farmers. Moreover, in meeting 

 with other professional people and through the services rendered by 

 the Office of Experiment Stations, they become acquainted with the 

 results of research throughout the country. It is neither necessary nor 

 feasible to duplicate much of the work done at other stations, ex- 

 cept as the results are not applicable under New Hampshire condi- 

 tions. Costs of research have increased greatly, thus making it all 

 the more necessary to select only the most important problems for 

 investigation. 



Beginning in July. 1954, the Experiment Station proposes to 

 publish quarterly the results of its research in a popular form. The 

 reports will be given general distribution and should keep farmer- 

 well informed currently as to the. progress of the Agricultural Experi- 

 ment Station's research progress.
