e0“Yields within tillage systems and between weed control treatments in 1982 were not significantly different because adequate rainfall reduced the effect of weed competition for soil moisture.”

Other claims from this paper (7)
- Intervention effect In wet 1982, conventional tillage produced significantly greater soybean grain yield than no tillage except under preemergence-only weed control.
- Intervention effect No-tillage soybean seed yields in 1983 and 1984 equaled or exceeded those under conventional tillage.
- Intervention effect No tillage conserved more soil moisture and increased soil moisture availability during drought in 1983 and 1984.
- Intervention effect No tillage reduced soybean water stress during pod filling in drought periods.
- Intervention effect Conventional tillage caused significantly greater early weed growth than no tillage in untreated plots in all three years.
- Intervention effect Soybean plants increased weed control by an average 36% under no tillage.
- Intervention effect Soybean plants increased weed control by an average 38% under conventional tillage.
