EXPERIMEXTAL FARMS 



7 GEORGE V, A. 1917 



Comparison of potatoes cut and coated with gypsum or land plaster, with sets not so 



coated and planted the same day, also cutting and coating, and not coating the 



sets two weeks before planting. 



"Variety experimented with: Gold Coin. 



Planted in rows 66 feet long, rows 30 inches apart, sets planted 12 inches apart. 



All planted May 8. 



All harvested September 21. 



By the table below it will seem that coated seed was in both instances superior 

 to uncoated seed in producing a crop, and that the seed cut fourteen days before 

 being planted gave better results than fresh-cut seed both when coated and uncoated. 



EXPERIMEXTS FOR EARLY CROP. 



An experiment was made in the planting and growing of potatoes in various 

 ways for early crop. 



First: from seed consisting of cut tubers. 



Second: from seed consisting of whole tubers, unsprouted. 



Third: from seed consisting of whole tubers, sprouted. 



Number of varieties, ten; four early, six late. ' 



Drills 30 feet long for each variety, and 30 inches apart. 



Sets planted 1 foot apart in drill, thirty of each variety. 



Manure in drills at the rate of 16 tons per acre. 



All seed planted on March 19, 1915. 



Harvested at intervals of two weeks, 10 feet of each variety at each harvesting. 



In the following tables: No. 1 represents cut tubers, No. 2 represents whole 

 tubers unsprouted. No. 3, represents whole tubers sprouted.
