Experiment Station, Wisconsin, 30.1 bushels; Lawrence Wadleigh, Rock- 

 ingham, 29.4 bushels; George Mansfield, Hillsboro, 27.2 bushels. 



Trials of oats and annual legumes showed the following yields per 

 acre in air-dry weight: Oats and hairy vetch, 4,544 pounds; oats and 

 spring vetch, 5,013 pounds; oats and peas, 5,749 pounds; Wilson soy 

 beans, 2,517 pounds; Manchu soy beans, 2,571 pounds; Wilson soy 

 beans and Hungarian, 4,085 pounds; Wilson soy beans and Japanese 

 millet, 3,565 pounds; Wilson soy beans and Sudan grass, 2,906 pounds. 



Early Cut Hay Gives More Protein 



To what extent does the date of cutting hay affect the amount of pro- 

 tein per acre? In an attempt to answer this question quadruplicate 

 plots of hay land were laid out on the University farm, were not top- 

 dressed and were harvested at ten-day periods beginning June 10. After 

 each harvest the hay from the plots was transported to a drier, es- 

 pecially constructed for the purpose, and evaporated to an air-dry basis. 



Hay cut June 10, when the heads were appearing, had the highest 

 percentage of protein. The greatest yield of protein per acre came June 

 .30, while the heaviest yield of hay per acre was obtained on July 10. 

 After this date the total yield decreased slightly, while the yield of 

 protein per acre fell off rapidly after June 30. 



The findings of the first harvest and of the second, conducted on all 

 plots September 2, indicate that a farmer in southern New Hampshire 

 is justified in haying in time to finish before July 1 instead of waiting 

 for that as a starting date. (Hatch Fund) 



Roughage Production Costs 



Reduction in the number of men used at silo-filling time has been 

 especially noticeable during the investigation of roughage-production 

 costs in New Hampshire by M. F. Abell. He finds it quite common 

 now for farmers to dispense with the man in the silo and the extra man 

 at the cutter and with the help of low and special racks, to reduce the 

 high labor cost of filling silos. 



He has obtained 225 silage records and 245 hay records and expects 

 to increase the number of each to 300. A check on the survey records 

 will be supplied by 12 detailed silage records and eight detailed hay 

 records. (Purnell Fund) 



Potato Marketing 



If potato growers in southern New Hampshire wish to compete with 

 the better producers in Coos county, they must obtain yields of at 

 least 250 bushels per acre, according to potato-marketing studies by 

 E. H. Rinear and M. F. Abell. On the basis of 300 bushels and 200 

 bushels for northern and southern New Hampshire respectively, the 

 Coos-county grower would net at least $25 more per acre at a price of 

 $1.50 per bushel to the consumer. 



During the fall of 1930 additional information was obtained from the 

 growers as to number of seconds graded out per 100 bushels, the price 

 received, method of selling, distance to market and amount of time re- 

 quired by each grower in marketing. When this material is analyzed
