168 AGRICULTURAL EXPERIMENT STATION. [Jan. 



III. Experiments with Field and Garden Crops. 

 (Fields C and D, 1889.) 



A short description of the work carried on upon these 

 fields during the preceding year, 1888, may serve as an 

 introduction to a brief statement of the course adopted in 

 1889. 



Fitld O, 18S8. — This field comprises an area 328 feet 

 long and 183 feet wide. It was ploughed the previous fall, 

 and again April 26 ; it was harrowed soon after, and fertilized 

 broadcast at the rate of six hundred pounds of line-ground 

 bones and two hundred pounds of muriate of potash per acre. 

 The field is divided into two parts, running from east to 

 west ; they are separated from each other by a passageway 

 three feet wide. The northern half of the field is 70 feet 

 wide and 328 feet long ; the southern half is the same length, 

 but 109 feet wide. 



The latter was again subdivided into three equal parts, 

 each 111 by 109 feet, or 11,990 square feet. The east end 

 of this field was planted with a mixture of vetch (vicia 

 sativa) and oats (variety Western). The middle division 

 was planted the same day with serradella and the western 

 with Southern cow-pea. Vetch and oats were seeded broad- 

 cast, and serradella and Southern cow-pea in drills, three 

 feet three inches apart. 



The northern half of Field C w^as occupied by a series of 

 crops in rows, running north and south, three feet three 

 inches apart, with the exception of the carrots, which were 

 planted in rows fourteen inches apart. The crops were 

 arranged in the following order, beginning at the east end : — 



Dauvers carrots, ninety rows. 



Welcome oats, three rows. 



Hairy vetch ( Vicia viUosa) , one row. 



Small pea {Lathyrus sativus), one row. 



Sulla {Hedysaru7n coronaria) , one row. 



Bird's-foot clover (Lotus corniculatus) , three rows. 



Lotus villosus, three rows. 



Sweet clover {Melilotxs alba), three rows. 



Early cow-pea, one row.
