readily cleaned. The onion seed plot at the Farm this year was not a fair test as many 

 varieties were grown and in order to keep them pure, the heads were put in paper 

 bags, thus undoubtedly reducing the yield.

' Below will be found the average yield per plant of some of the different varieties 

 of vegetables, together with a germination test. 



YiEL'DS of seed from diiferent vegetable plants, Central Experimental Farm, 1915. 



The following number of plants of each kind of vegetable was grown by the 

 Horticultural Division in 1915. A note regarding the total amount of seed grown is 

 also appended. It must be remembered that many of the varieties were grown under 

 cotton covers to keep them from crossing and that this materially reduces the yield. 

 The average yields per plant referred to in table No. 1 were computed from plants 

 that were not covered and hence will not compare with those here referred to, which 

 are total yields of covered and uncovered. The piece of land used for growing these 

 seeds was 100 by 40 feet in dimensions. 



Number of Plants and Weight of Seed Produced at Central Experimental Farm, 1915. 



The above estimate of value is based on the retail price per pound of the diflferent 

 kinds of seed. 



N.B. — As the cabbage plants were nearly all covered, the amount of seed set was 

 very light.
