Other claims from this paper (9)
- Intervention effect RT yielded 10.8 Mg per hectare in 1995, significantly above CP and GCP.
- Intervention effect GRT yielded 10.3 Mg per hectare in 1995, significantly above CP and GCP.
- Observation CP grain yield ranged from 1.3 in 1992 to 8.4 Mg per hectare in 1993.
- Observation GRT had the highest four-year average yield excluding grass strip area, 7.3 Mg per hectare.
- Observation GCP four-year average yield was 7.2 Mg per hectare.
- Observation RT four-year average yield was 6.9 Mg per hectare.
- Observation CP four-year average yield was 6.7 Mg per hectare.
- Intervention effect Corn yields improved in 1994 and 1995 when grass height was limited.
- Recommendation The authors propose contour ridge tillage with grass strips to sustain crop productivity.
