I. SUMMARY OF FIELD RESULTS WITH THE 

 USE OF FERTILIZER ON STRAWBERRIES. 



In the spring of 189T, at the request of the Oswego County Fruit- 

 growers' Association, the Horticultural Department of Cornell 

 University planned, and now has under way, a series of tests with 

 different fertilizers for the purpose of determining, if possible, the 

 one best suited to the needs of the strawberry when grown as a field 

 crop. These experiments were begun by the late E. G. Lodeman, 

 and they have been continued under the personal supervision of 

 C. E. Hunn. 



The three essential fertilizers, nitrogen, phosphoric acid and 

 potash, were used separately and in combinations in different 

 weights and seasons, careful notes being taken both as to growth of 

 plant and yield of fruit. The fertilizers were applied to young 

 plantations in spring after the first tillage and before the j^lants 

 bloomed, a year in advance of the recorded crop. The materials 

 were scattered alongside tlie row, within a few inches of the plants, 

 and were cultivated in. The plats were located on a variety of 

 soils, ranging from typical strawberry soil, i. e., gravelly loam, 

 throuo^h meadow land to black muck. 



In 1897, in cooperation with the Association, six plats, in as many 

 different localities, Avere selected and a careful line of experiments 

 was planned. But five of these beds were continued through the 

 year, the sixth liaving been disturbed by the digging of plants for 

 sale. Tables '1 to 5, inclusive, give the results of the first year's 

 work (1897). 



The second year (1898) the plats were reduced to three in num- 

 ber, one on good strawberry soil, one on meadow land, and one on 

 good wheat land. Tables G to 8, inclusive, give results of the second 

 year's work. h\ 1899, no experiments were made. In 1897 and 

 1898, the plats were of various sizes, but in the tables below (Nos. 

 1-8) the fertilizers and yields are figured to the acre.
