Abstract
Nitrogen and chlorophyll were determined in leaf samples from field experiments with pineapples. In the most striking of 4 exps. the chlorophyll content varied from 1.02 mg. per 100 sq. cm. with no N added as fertilizer to 13.40 mg. chlorophyll with 38.4 pounds N per 1000 plants. A similar but less decided trend was obtained in the other exps.
