204 AGRICULTURAL EXPERIMENT STATION. [Jan. 



The various mixtures of fertilizers used l^y 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 May 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 

 sul>sequent tabular statements of the yield of the crops show 

 the date of maturity and the cjuantity oljtained at different 

 dates : — 



Yield of Spinach {Variety Neiu Zealand). 



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.
