TOMATOES 



Fertilizer containing both yielded $24.46 profit per acre. 



Dried blood or nitrate of soda alone does not seem to be 

 necessary for the largest return, but a combination of both 

 of these seems to be best. That is for the largest returns. 



From all experiments that have been carried on, there is 

 evidence enough to believe that two per cent, of nitrogen in 

 the fertilizer formula is best for tomatoes, either in the form 

 of dried blood or nitrate of soda. Experiments have been 

 carried on with six per cent, potash and ten per cent, potash, 

 and the returns were the same. 



Mr. Haw (Onondaga County) : Did you have a check on 

 that potash? 



Mr. Wilkinson: The test carried on in the western state 

 included plots without potash, with six per cent., ten per 

 cent, and a great many others, including checks. There are 

 some locations in New York State where ten per cent, potash 

 is absolutely necessary in order to get a yield of tomatoes. 

 Now, in what form do you use this potash, muriate or sul- 

 phate? From the experiments carried on in these midwes- 

 tern colleges, it has been found that the muriate yield per 

 plot varied from one to five and one-half tons; with the sul- 

 phate it varied from one and one-third to six and forty-one 

 hundredths tons. In each case the sulphate appeared to be 

 superior to the muriate as a source of potash. Thus, there 

 was an average difference in all experimental work of twenty- 

 two per cent, in favor of the sulphate. 



Question: Did this fertilizer have any effect upon the 

 color or ripening? 



Mr. Wilkinson : It probably did. From all experimental 

 work that I have been able to look over, I have found that 

 practically everyone agrees in the Mid-West that about ten 

 per cent! acid phosphate is necessary. In New York State 

 we are not willing to say that ten per cent, of acid phosphate 

 is necessary. In fact, we use a fertilizer with probably two 

 per cent, less of phosphoric acid. 



In Indiana they have determined under a three-year test 

 that a 2-10-6 formula was best for their conditions, and the 

 fertilizer made up in this way would consist of one hundred
