Abstract
“Standard yield variety” and “high-yielding variety” of rice, winter wheat, maize, soybean, potato, beet, and sunflower were grown, and the relationship between root growth and absorption of nitrogen was studied. To estimate the role of root in nitrogen absorption, nitrogen absorption rate (ΔN, g N m−2 d−1) was parameterized into root dry weight (RW, g m−2) and specific absorption rate of nitrogen per root dry weight (SARN, ΔN RW−1).Keywords
