Other claims from this paper (16)
- Intervention effect Irrigation significantly increased yield of each soybean cultivar at each row spacing in each year.
- Intervention effect There were no yield differences among the I1, I2 and I3 irrigation regimes at either row spacing.
- Observation Average yield without irrigation was 2.86 Mg/ha in 1982.
- Observation Average yield without irrigation was 3.20 Mg/ha in 1983.
- Observation Average yield without irrigation was 2.97 Mg/ha in 1984.
- Intervention effect Yield increase from irrigation was 10% in 1982.
- Intervention effect Yield increase from irrigation was 8% in 1983.
- Intervention effect Yield increase from irrigation was 16% in 1984.
- Observation Irrigated yield of cultivar Forrest was 3.47 Mg/ha.
- Observation Irrigated yield of cultivar Centennial was 3.17 Mg/ha.
- Observation Irrigated yield of cultivar Braxton was 3.40 Mg/ha.
- Observation Water use efficiency was greatest with cultivar Forrest.
- Intervention effect Irrigation after R2 increased lodging by up to 50%.
- Mechanism Severe lodging may have reduced irrigated yields.
- Mechanism Relative yield increase from irrigation was limited by adequate rainfall and soil water storage, which gave high yields without irrigation.
- Recommendation The most efficient water regime was one based on an early maturing cultivar.
