Other claims from this paper (10)
- Intervention effect Monocropping of wheat is not a feasible replacement for winter wheat-soybean doublecropping in a nonirrigated environment on clay soil.
- Intervention effect Wheat yields were higher in the monocrop treatments than in the doublecrop in most years.
- Intervention effect Wheat yields from subsoiling alone (TRT 3) were among the highest each year.
- Intervention effect Net returns from subsoiling alone (TRT 3) were among the highest in only 2 of the 4 years.
- Intervention effect Combined net returns from the wheat-soybean doublecrop (TRT 6) were among the highest in all years.
- Intervention effect Combined net returns from the wheat-soybean doublecrop (TRT 6) were positive in only 2 of the 4 years.
- Observation Soybean yields in the doublecrop averaged only 14.8 to 25.2 bu/acre.
- Association Expenses of summer fallow maintenance for monocropped winter wheat were not offset by sufficiently higher yields.
- Intervention effect Yield of wheat in the subsoiled and bedded treatment (TRT 5) never significantly exceeded that of the subsoiled flat-planted (TRT 3) or bedded (TRT 4) treatments.
- Intervention effect The 4-year mean yield of flat-planted monocropped wheat without subsoiling (TRT 1) was 7.5 bu/acre below that after subsoiling (TRT 3).
