Maize root response to N in the greenhouse and field

  • E. L. Anderson
Short Communications

Summary

Root growth and morphology were compared between seven week old maize plants grown in the greenhouse and in the field. The plants were similar in shoot dry weight and the partioning of N and dry matter to roots were similar except for the field grown plants in 1983. Field grown plants had greater root mass per length and greater calculated diameter than greenhouse plants. Nitrogen fertilization decreased N and dry matter partitioning to the root system in all three environments.
