Summary
The influence of 12 combinations of 5 different relative anion ratios and 3 different relative cation ratios in a nutrient solution on the production of tomato plants has been investigated in gravel culture during the years 1962, 1963 and 1964.
There were 5 N levels, respectively 36.3%, 54.4%, 63.1%, 72.5% and 86.0% of the total anions in equivalents and 3 K levels, respectively 66.8%, 33.7% and 22.4% of the total cations in equivalents.
Although differences were small, there was a significant reduction of earliness and total production for the highest N level. The other N levels showed no difference.
Earliness and total production were significantly better with the lower K levels, but again differences were small.
The influence of the composition of the nutrient solution on the production of the tomato plant was shown to be very small.
