EXPEEIMEXTAL FARMS 



5 GEORGE v., A. 1915 



Tlie land for this experiment was very firm this spring, and obviously was not in 

 great need of packing. It was therefore to be expected that the packing would not 

 have a decidedly beneficial effect. From the figures obtained we would not make any 

 observations as to which kind of packer will give best results, nor as to what time of 

 packing is best, but might point out that the three plots packed after ploughing in 

 the summer, and again after seeding in the spring gave the highest yields. 



Soil Packing for \Yheat Sown oii Spring Ploughed Stubble Land. 



The plots for this experiment grew wheat in 1912. They were ploughed April 16 

 and treated as described below. The wheat was sown April IT at the rate of Ig bushels 

 per acre. Considerable variations was observed in the time required for germination, 

 heading out, and ripening, as will be noted in the following table: —

We are unable to draw any conclusion from these results except that the two 

 xmpacked plots were a little later and more uneven in germinating. 



SOIL packing for wheat on fall ploughed stubble land. 



The plots for this experiment grew wheat in 1912. They were ploughed October 

 10, 1912. Those on which fall packing is given were packed October 15. The spring 

 packing was done April 16 and 18. Wheat was sown April 19, at the rate of If bushels 

 per acre. The date of coming up and ripening is given in tabular form below. All 

 headed out June 28, except plot 22, which vras two days later.
