Other claims from this paper (10)
- Intervention effect Without irrigation, corn and live grass depleted available soil water and corn died.
- Intervention effect With irrigation, corn and live grass used soil water faster than corn in dead sod until canopy closure.
- Intervention effect After canopy closure, corn in killed sod used more soil water than corn in live sod.
- Intervention effect Without irrigation, corn yield was zero with live sod.
- Intervention effect Without irrigation, corn yield was about 1000 kg/ha on killed sod.
- Intervention effect Without irrigation, corn yield did not respond to nitrogen rates of 112, 224 and 448 kg/ha.
- Association With irrigation, corn yield rose in proportion to nitrogen level and live sod amount.
- Observation Irrigated corn yielded 140 kg/ha with 112 kg/ha nitrogen on live sod.
- Observation Irrigated corn yielded 9,980 kg/ha with 448 kg/ha nitrogen on killed sod.
- Recommendation The authors conclude corn can be grown in grass sod on sloping Piedmont fields without serious soil erosion.
