1899.] PUBLIC DOCUMENT — No. 33. 69 



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

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

 potatoes; and, as a second crop, turnips. 



Clyde Strawberries. — 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. 



Long Standing Spinach. — Three rows of this crop were 

 planted in each plot May 7. All germinated well, but by 

 June 9 many plants were dying on plots 1 and 4 (sulphate 

 of ammonia and muriate of potash, and sulphate of ammonia 

 and sulphate of potash), Avhile 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, 1J; Plot 2, 1561; Plot 3, 

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



The average yields in pounds produced by the different 

 fertilizers* were : — 



Manure :il one (Plot 0), 88.7 



Average of manure and muriate of potash (plots 1, 2 and 8), . 78.5 



Average of manure and sulphate of potash (plots 4, 5 and 6), . 82.3 



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



Average of manure 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 muriate 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 

 much smaller crop than the nitrate of soda. The most im- 

 portant fact brought out is the marked superiority of the 

 latter as a source of nitrogen for spinach. 



/ /<iit son Lettuce. — Two rows of this crop, planted May 

 7, were grown 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 sulphate of potash," etc It 

 should be remembered that dissolved bone-black was applied to all except Plot 0, 

 and that every plot received material supplying both nitrogen and potash as well as 

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

 each plot, see page 66.
