POTATOES — PLANTING AT DIFFERENT DISTANCES ArART. 



For the past six years an experiment has been tried in planting the sets at differ- 

 ent distances apart in the rows, the rows in each case being 2£ feet apart. The best 

 average results have been obtained, so far, by planting the sets 14 inches apart, 

 though the results from planting 12 inches apart are nearly the same. The yields of 

 unmarketable potatoes in this test did not vary much except where the sets were 

 planted 8 inches apart, but in this case there was a somewhat larger proportion of un- 

 marketable potatoes than in the others. For the first four years of this test only one 

 variety was used, but during the last two years two were planted and their average 

 yield given. This year the varieties planted were Everett and Uncle Sam, an early 

 and a late variety. The amount of seed per acre used may appear large, but from ex- 

 periments conducted here it has been found advisable to use large sets. 



POTATOES PLANTING AT DIFFERENT DEPTHS. 



An experiment has been conducted during the past four years in planting pota- 

 toes at different depths in rows 1\ feet apart and 12 inches apart in the rows. The 

 sets had at least three eyes each, and were about uniform in size. The soil was sandy" 

 loam, every year. Level cultivation was adopted, and thus very little soil was thrown 

 on the potatoes after they were covered at the time of planting. The following table 

 ghows that the best yields were obtained from planting the sets only 1 inch deep. As 

 the relative yields from the different depths of planting have not been the same every 

 year, it will be necessary to continue this test for some time before accurate conclu-
