EXPERIMENT STATION BULLETINS

As soon as the ground was in proper condition the following spring, it was plowed, 

 rolled and harrowed at frequent intervals, until the time of planting. The early 

 varieties were planted May 14, and the late ones June 4. The seed was treated 

 with corrosive sublimate (1-2,000) for one hour, and the crop showed a very small 

 amount of scab. At the time of planting, furrows six inches deep and forty-two 

 inches apart were made and each variety was given a space in the row forty feet 

 long. Two pounds of each variety was used for seed and was cut into twenty-five 

 pieces, which were dropped eighteen inches aparr. The seed was coverd with a 

 lioe, after which the ground was rolled with a heavy roller to pack the soil. To 

 prevent the evaporation of moisture from the soil and hinder the growth of small 

 weeds, a weeder was used at intervals of four to six days until the plants were 

 about five inches high, after which a Planet. Jr., cultivator Avas used, strictly adher- 

 ing to level culture. Both early and late varieties were watered by the irrigating 

 system about the time of setting and once when the tubers were half gi'own. The 

 season was very favorable for the growth of the plants, and as they were not killed 

 by frost until the middle of October, many varieties continued to grow, even though 

 the tubers reached edible maturity earlier in the season.
