e0“In 1986, maximum yields achieved in the 6‐year continuous no till (NT) [5.82 Mg/ha] and first year no till (AT) [5.64 Mg/ha] were significantly greater than that of the 6‐year continuous conventional till (CT) [3.67 Mg/ha]”

Other claims from this paper (7)
- Intervention effect In 1986, first year no till yielded significantly more than continuous conventional till.
- Observation The drier 1987 season showed no yield differences between tillage treatments.
- Intervention effect First year no till required a higher fertilizer N rate for maximum yield than continuous no till in 1986.
- Observation Early 1986 nitrogen uptake ranked CT below AT and NT.
- Observation Early 1986 growth response ranked AT below CT below NT.
- Observation Critical ear leaf N values did not differ between NT and CT within either year.
- Recommendation The authors infer that a plant N norm from one tillage system may assess corn N status in another.
