48 BULLETTl^ 1082, U. S. DEPARTMEXT OF AGRICUI.TUEE. 



The turn-off of bulbs from the acre in 1919 will be seen to total 

 86,994. In 1920 the turn-off totaled 163,845 bulbs, but for certain 

 reasons it was desirable in that year to get rid of as many bulbs of 

 some varieties as possible. Consequently, all bulbs of these varieties 

 that would flower were disposed of. Many of these bulbs were 

 smaller than should have been sold for anything but planting stock. 

 Of this latter class there were, as nearly as can be estimated, 58,720. 

 Deducting this from the total, there is a net merchantable turn-off of 

 105,125 bulbs from the acre in 1920. 



The yield in 1920 is further slightly augmented by the fact that 

 there were planted on the acre about 10,000 bulbs of all sizes which 

 had been used for bedding on the grounds of the Department of 

 Agriculture at Washington, D. C, in the spring of 1919. These, while 

 not normal for first-quality stock, nevertheless probably gave a greater 

 proportion of merchantable bulbs in 1920 than the average run of the 

 Bureau of Plant Industry planting stock. The reproduction in these 

 stocks, however, was much below normal. These relations are well 

 brought out in the narrow ratio between the number of bulbs planted 

 and the number turned off as merchantable in some varieties in 

 Table 7. In Wouwerman only 2,099 were planted and 1,900 were 

 turned off. This may necessitate reducing the total turn-off to 

 100,000. 



Table 7 contains lists of all the varieties grown on the tested acre 

 of ground devoted to tulips each year. The blanks opposite the 

 varieties in the "Marketed" column indicate in practically every 

 case that all the stock was planted back in the autumn of 1920. The 

 1919 list, as will be seen, is comparatively short in number of varieties 

 and made up very largely of single earlies, which were the only stocks 

 grown on the new place that year.
