204 AGRICULTURAL EXPERIMENT STATION. [Jan. 



The various mixtures of fertilizers used by us in the 

 experiments under discussion provide by actual supply for 

 one-half of the available nitrogen actually called for to meet 

 the demand as above pointed out. A liberal cultivation of 

 peas and beans cannot fail to benefit the nitrogen resources 

 of the soil. 



Potatoes were planted ^lay 10 ; spinach and beets were 

 sown May 15 ; lettuce and cabbage plants were set out May 

 15 ; tomatoes were set out May 29 ; celery plants were set 

 out June 20. The seeds in every case were taken from the 

 same lot ; the young plants were raised under corresponding 

 conditions in the same hot-bed, and a corresponding number 

 transplanted in each plat. All plats were kept clean from 

 weeds and treated in a like manner during the season. The 

 crops were harvested whenever fit for the market. The 

 subsequent tabular statements of the yield of the crops show 

 the date of maturity and the quantity obtained at different 

 dates : —

The seed was sown May 10 ; the crop was harvested July 

 12. The low yield of Plat 4 was due to poor germination 

 of the seed.
