1899.] PUBLIC DOCUMENT — No. 88. i\9 



The crops the past season have been : strawberries (Clyde) , 

 spinach, lettuce, table beets, tomatoes, cabbage, celery and 

 potatoes ; and, as a second crop, turnips. 



CJi/de Sfratvberries. — Three rows were set in each plot. 

 The growth was vigorous and healthy on all plots. Plots 4, 

 5 and 2 now show a slight superiority over the others, while 

 Plot is the poorest. All are well stocked, in matted 

 rows. 



Lowj Standing Spinach. — Three rows of this crop were 

 planted in each plot May 7. All germinated well, but l)y 

 June 9 many plants were dying on plots 1 and 4 (sul[)hate 

 of anmionia and nuiriate of potash, and sulphate of anmionia 

 and sulphate of potash) , while nearly all the plants in these 

 plots appeared yellow and sickly. All the spinach was har- 

 vested in two cuttings. The yields in pounds were as 

 follows: Plot 0, 69; Plot 1, 1^; Plot 2, 156^; Plot 3, 

 77f ; Plot 4, 13^; Plot 5, 1591; plot 6, 73|. 



The average yields in pounds produced by the ditfereut 

 fertilizers* were : — 



Manure alone (Plot 0), 88.7 



Average of manure and muriate of potash (plots 1, 2 and 3), . 78.5 



Average of manure and sulphate of potash (plots 4, 5 and G), . 82.3 



Average of manure and sulphate of ammonia (plots 1 and 4), . 7.4 



Average of maniu'e and nitrate of soda (plots 2 and 5), . . 158.0 



Average of manure and dried blood (plots 3 and 6), . . 75.8 



It will be noticed that the nuiriate of potash plots are 

 inferior to those receiving sulphate of potash, though the 

 difference is small. The sulphate of ammonia plots proved 

 almost an absolute failure, while the dried blood gave a 

 muc^h smaller crop than the nitrate of soda. The most im- 

 l)ortant fact brought out is the marked superiority of the 

 latter as a source of nitrogen for spinach. 



Hanmn Lettuce. — Two rows of this crop, planted May 

 7, were gi'owu in each plot, the plants being brought by 



♦ To enable the reader the better to make comparisons, the plots are characterized 

 as "manure and muriate of potash," "manure and suli)liate of i)<)tash," etc. It 

 should bo remembered that dissolved l)onc-l)lack was applied to all except Plot 0, 

 and that every plot reaMved material supplying both nitrojjen and potash as well as 

 phosphoric acid in addition to the manure. For the fidl list of fertilizers applied to 

 eacli plot, see page 66.
