From these results, we learn that the Early American Purple Top 

 and the White Ep-"- -"""-ieties are not only among- the freest from rot, 

 but they are also heavy yielding- varieties. The Jersey Navet turnip, 

 vhich formerly g^ave very g-ood yields, has given unsatisfactory returns 

 during the past few seasons ; so much so that we have dropped it from 

 our lists entirely in our experiments with fall turnips in 1904. 



Selection of Seed. Large, medium, and small sized turnip s^ed 

 has been sown on separate plots in each of four years. The experiment 

 was conducted in duplicate each year, so that we now have average 

 results of eight separate tests. The seed used on the different plots 

 was of the same variety and of practically the same quality, except in 

 size. The average yields produced from the different selections for the 

 four years are as follows : Large seed, 25.4 tons; medium-sized seed, 

 21.7 tons; and small seed, 16.2 tons per acre. 



Parsnips. 



Parsnips have not been grown very generally as a farm crop in 

 Ontario. Enquiries have been received occasionally, however, asking 

 about the yields of parsnips as compared with other classes of roots for 

 cultivation as a stock food. Four varieties have now been grown for 

 five vears, the averap-e yield of roots per acre being as follows: Buck- 

 bee's N*"---" Sugar, 11.:; tons; New Ideal Hollow Crown, 11 tons; Im- 

 proved Half Long, 10.3 tons; and Improved Long Smooth, lo.i tons. 

 The Sutton's Cattle variety, which has been grown for four years in 

 succession has given an average of 10.2 tons of roots per acre. It will 

 be observed that the parsnips have yielded considerably less per acre 

 than the leading varieties of mangels, sugar beets, turnips, or carrots. 



Kohl Rabi. 



This crop is somf^^^imes grown for food for stock in some of the 

 older countries. The root of the kohl rabi is somewhat like that of 

 cabbage; while the leaves resemble those of Swede turnips. The valu- 

 able part of the plant, however, grows about three inches above the 

 level of the ground in the form of a bulb. Kohl rabi makes a very nice 

 food for domestic use, and is prepared for culinary purposes in much 

 the same way as Swede turnips. The seed of kohl rabi resembles very 

 closely that of Swede and fall turnips, and the crop is grown in much 

 the same manner as turnips. 



The following is the average yield in tons per acre of each of two 

 varieties of kohl rabi grown in the experimental grounds for six years : 

 Early White Vienna, 20.7 tons and Earliest Erfurt, 18.2 tons. The 

 Goliath Purple variety, which has been grown for tliree years, gave an 

 average of 16.7 tons per acre. In the crop of 1904, the yields were 

 very high, being as follows : Early White Vienna, 27 1-2 tons; Earli- 

 est Erfurt, 26.9 tons; and Goliath Purple, 18.3 tons per acre. It will 

 be seen from these results that the Early White Vienna gave the larg- 

 est yield per acre in 1904, and also in the average of six years.
