Other claims from this paper (8)
- Intervention effect Deep placement of both fertilizers significantly increased plant nitrogen content.
- Intervention effect Coated urea gave 67.2 g seed yield per plant, above the control.
- Intervention effect Lime nitrogen gave 70.6 g seed yield per plant, above the control.
- Intervention effect Labeled nitrogen absorption tended lower with lime nitrogen than coated urea at R3 and R5.
- Intervention effect At R7 nitrogen recovery was 70% with lime nitrogen, higher than 61% with coated urea.
- Intervention effect At R7 nitrogen from fixation was 32.1 g m -2 with coated urea, above control.
- Intervention effect At R7 nitrogen from fixation was 31.1 g m -2 with lime nitrogen, above control.
- Mechanism The authors suggest continuous nitrogen supply at lower roots promotes shoot growth, leaf photosynthesis, nitrogen fixation and seed yield.
