fall after the first harvest and often lives over into the second season, 

 it seems much superior to field peas and preferable to common vetch 

 for forage. {Hatch Fund) 



Top-Dressing for Grass Hay 



Top-dressing of grass hay lands was begim on the college fanii in 

 1933 to test the efficiency of the more important nitrogen carriers, to 

 compare these wdth equal quantities of nitrogen in mixed fertilizers, and 

 to try different dates and different amounts of the same nitrogen car- 

 rier. Each of the 14 plots is about one-five hundredth of an acre 

 in extent. {Hatch Fund) 



Spray or Dust Potatoes 



Either spraying or dusting is satisfactoiy for potatoes in a season 

 like 1933 if the job is properly done, according to a comparative ex- 

 periment on the Lane farm, Chichester. {Hatch Fund) 



More Evidence on Early Haying 



Time-of-cutting studies on yield and feed value of hay have been 

 continued, following the publication early in 1933 of the conclusions of 

 trials in 1930, 1931, and 1932. The facts point out that grass hay 

 such as timothy, if it is to be of most value for dairy cows, should be 

 hai-vested before the period of bloom. This means starting haying as 

 early as June 15 in southern New Hampshire and not later than June 

 25 in the northern section. {Hatch Fund) 



No Difference From Broadcasting, Drilling Fertilizer 



To compare broadcasting versus drilling fertilizer for potatoes and 

 to determine the development of scab at different pH levels, one acre 

 of the crop was grown on the Ireland farm in Greenland in 1933 on a 

 piece of land which had been in sweet clover the previous year and 

 which had been limed and treated with basic slag as a lime carrier, 

 both at different rates. The methods of applying the fertilizer showed 

 no significant differences in yield. The use of basic slag resulted in 

 much less scab than did the lime, and the former was less effective 

 in correcting acidity. {Purnell Fund) 



Nitrogen Shines in Pasture Research 



The dry year of 1932 resulted in universal response to nitrogen in 

 the investigations on top-dressing old pastures. This research is con- 

 tinuous on the Seavey Brothers' fann, Stratham, and in seven other 

 widely scattered regions of the state. What 1933 will show depends on 

 the chemical analysis yet to be made of the harvested grass. 



Because of the possibility of different results for the Connecticut val- 

 ley, an experiment was started near Claremont this year by F. S. 

 Prince, T. G. Phillips, P. T. Blood and G. P. Percival. Fifteen plots 

 were staked out and treated with different nitrogen carriers and varia-
