Abstract
Cabbage plants were grown in nutrient solutions containing 3 levels of nitrogen (as NaNO3; 10, 100, 500ppm N) combined with 3 levels of sulfur (as Na2SO4; 1, 10, 50ppm S), and the effects of the nitrogen and sulfur supply on the growth and the chemical composition of the plants were studied.Total plant dry weight increased with an increase in the S supply when the N supply was 100 or 500ppm, but was always small when the N supply was 10ppm, irrespective of the S supply. The highest cabbage-head yield was obtained at 100ppm N and 10ppm S, while little cabbage-head yield was obtained at 10ppm N or 1ppm S. The total N content in each organ increased greatly with an increase in the N supply and decreased slightly with an increase in the S supply. The total S content incresased greatly with an increase in the S supply and decreased slightly with an increase in the N supply. A total N content below 2% and a total S content below 0.1% on a dry basis in the outer leaves was found to be insufficient for cabbage-head formation. Cabbage-head development was most efficiently when the total N/S content ratio was between 10 and 20, although the ratio fluctuated widely, from 4 to 235. N-deficient plants contained less sugars and more starch as compared with the N- and S-sufficient plants. S-deficient plants contained less sugars and 80% ethanol -insoluble protein N and more 80% ethanol-soluble non-protein N.
