Thus, the objective of this study was to quantify the morphological response of maize roots to N. Growth chamber and field studies were conducted. Fieldgrown maize was sampled during the 4 weeks after emergence to evaluate differences between field and growth chamber data. Numbers of seminal roots and lengths of the seminal root system did not increase substantially after 8 days. The nodal root system increased exponentially from 1.6 m at 8 days after emergence to 21 m at 29 days after emergence. Using the slant-board culture technique, maize plants grown in a growth cham. ber received 0, 21, 42, 105, or 210 ppm total N from 50 ROOT LENGTH ROOT APEX NITRATE SLANT-BOARD. Maizlish, N.A.
