Other claims from this paper (13)
- Association Double-cropped soybean yield varied by residue management and soil moisture, with no practice best in all years.
- Intervention effect Plowing gave significantly higher double-cropped soybean yield in four years.
- Intervention effect Disking gave the highest double-cropped soybean yields in three years.
- Intervention effect In three of eleven years soybean grain yield did not differ significantly by residue treatment.
- Intervention effect The plow system averaged 23.2 bu/acre, exceeding burn-disk by 2.4 and disk only by 1.8 bu/acre.
- Intervention effect Plowing significantly increased double-cropped soybean seed weight and leaf potassium concentration.
- Intervention effect Disking increased soil bulk density regardless of year.
- Intervention effect Residue management significantly affected soil moisture, but differences were generally small.
- Intervention effect Earlier residue management had no significant effect on yield, seed weight, and leaf N, P and K in subsequent full-season soybean.
- Intervention effect Earlier residue management had no significant effect on yield, seed weight, and leaf N, P and K in subsequent winter wheat.
- Observation Soil pH, organic matter, available P and exchangeable K changed little after six cycles.
- Recommendation The authors judge the small plow yield advantage insufficient to cover added tillage costs.
- Recommendation The authors expect little long-term effect of residue practice on later yield or soil quality in rotations double-cropped every two or three years.
