When 12 species of vegetable were supplied with NO3 in solution culture, growth was generally better in the high N than in the low N regime, although kidney beans grew better in low N; the pH of the solution had almost no effect on growth. Vegetables supplied with NO3 + NH4 grew well under all cultural conditions and growth was better than or almost as good as that in the NO3 treatment. In plants grown with NH4 growth was reduced with high N at pH 5 but not with low N at pH 7.
