EXPERIMENT STATION RECORD. 



some of the experiments conducted for several years in succession. A 

 previous bulletin on this work has been noted (E. S. R., 7, p. 394). 



Ninety-two varieties were sown on plats at the rate of 2 bu. per acre 

 during the first week of September. All varieties ripened between 

 July 14 and 21 and gave an average of 3.4 tons of straw and 42.9 bu. 

 of grain per acre, and an average weight of grain of 63 lbs. per meas- 

 ured bushel. Of 48 varieties grown for 5 years in succession Dawson 

 Golden Chaff, Early Genesee Giant, Egyptian, Imperial Amber, Early 

 Eed Clawson, Reliable Golden Drop, Russian Amber, and Egyptian 

 Amber, in the order named, gave the best results, the average yields 

 varying from 45.3 to 52.6 bu. per acre. Among 44 new varieties of 

 winter wheat grown in 1898 Gold Coin, Silver Dollar, White Golden 

 Cross, Pedigree Genesee Giant, Oregon, Forty Fold, and Zerena were 

 the most productive, yielding from 50 to 52 bu. per acre. The average 

 yield of Dawson Golden Chaff and Early Genesee Giant, grown for 

 3 years in succession on 25-acre fields, was about 36 bu. per acre. The 

 average results for 5 years show that Egyptian Amber, Emporium, 

 Bissell, Long Berry Red, Turkish Red, and Geneva were least affected 

 with rust. During a period of 9 years there has been a variation from 

 26.1 to 52.9 bu. in the average yield of grain per acre, from 1.2 to 4 tons 

 in the average yield of straw per acre, and from 55 to 63.3 lbs. in the 

 average weight of grain per measured bushel. 



The results from the test in seed selection show that large plump 

 seed produced 6.3 bu. per acre more than small plump seed and 8.25 

 bu. more than shrunken seed. Seed grain which had been broken in 

 threshing yielded only one-fifth as much as large plump seed. 



The results of sowing winter wheat on different dates indicate that 

 best results are obtained by sowing during the last week in August or 

 the first week in September. 



In tests conducted for 5 years in succession 1£ bu. of seed per acre 

 gave better results than 1 bu. per acre and similar results to using 2 

 bu. of seed per acre. It was also found that sowing broadcast and 

 drilling with the grain drill gave results practically alike. The follow- 

 ing table gives the results of experiments in the preparation of soil for 

 winter wheat:
