EXPERIMEiVTAL FARMS 



7-8 EDWARD VII., A. 1908 



The one-tenth acre plots of wheats barley and oats had by the end of 1903 become 

 infested with several troublesome perennial weeds, hence it was thoug'ht best to sow 

 only one-half of each plot with grain in 1904, devoting the other half to a hoed crop 

 to clean the land. On this account no clover was sown on any of the cereal plots in 

 1904, and one-half of the wheat plots was sown with mangels, one-half of the barley 

 plots with potatoes, and one-half of the oat plots with carrots, computing the yields 

 of grain from a one-twentieth acre plot in each case. Similar hoed crops were sown 

 in 1905 and 190G changing the position of the varieties from year to year. 



INDIAN COEN PLOTS. 



The experiments with the plots of Indian corn have been conducted with the object 

 of obtaining the largest weight of well matured green fodder for the silo, and to have 

 the corn so far advanced when cut. that the ean? shall be as far as is practicable in 

 the late milk or glazed condition. Each plot has been divided from the outset into two 

 equal parts, on one of which — known as No. 1 — one of the stronger growing and some- 

 what I'ater ripening sorts has been tried, and on the other, marked No. 2, one of the 

 earlier maturing varieties. During the first four years one oif the Dent varieties was 

 tested under No. 1. On the other half of the plot (No. 2) one of the Flint varieties 

 was grown. For the first four years the No. 1 series was planted in drills 3 feet apart, 

 using about 24 pounds of seed to the acre and thinning the plants, when up, to 6 or 8 

 inches, and the No. 2 in hills 3 feet apart each way with 4 or 5 kernels in a hill. 

 During the past eight years both sorts have been grown in hills. 



In 1900 no crop of Indian. corn was grown on these plots, but clover was sown in 

 its place on May 5, in the proportion of 12 pounds per acre. This made a strong 

 growth, was cut twice during the season and left on the ground to decay, so that when 

 ploughed under, the land might get the full benefit of the clover crop. The clover 

 was allowed to remain growing until May 20, 1901. It was then ploughed under 

 about 6 inches deep, and harrowed well before the corn was planted. Clover was sown 

 cg^in in 1903, and ploughed under in May, 1904. Corn was planted in 1905 and 1906. 

 In 1906 it was planted on May 28, and cut for ensilage September 13. 



EXPERIMENTS WITH FERTILIZERS ON PLOTS OF INDIAN CORN, CUT GREEN 



POR ENSILAGE. 



o 



Fertilizers applied each year from 1888 to 

 1893 or 1899. No fertilizers used from 

 that time to 1905. Clover sown in 1900 

 in place of the corn and ploughed under 

 in May, 1901, before the corn was planted 

 In 1003 clover was again sown and 

 ploughed under in May, 1904. In 1905-C 

 fertilizers again applied as in 1898. Clover 

 discontinued.
