- Intervention effect First-cut dry matter yield rose significantly with nitrogen level.
- Intervention effect First-cut dry matter yield rose significantly as irrigation interval shortened.
- Intervention effect Gypsum significantly increased first-cut dry matter yield.
- Observation Reduced irrigation frequency had a greater effect than 3N fertilization.
- Observation Gypsum benefit was 5% at the seven-day irrigation interval.
- Intervention effect Combined treatment increased 1978 yield from 1.84 to 6.12 tonnes/ha.
- Intervention effect Combined treatment increased 1979 yield from 3.20 to 7.23 tonnes/ha.
- Intervention effect Height and leaf area index increased with gypsum.
- Intervention effect Height and leaf area index increased as irrigation interval fell from 15 to seven days.
- Intervention effect Gypsum alone significantly increased germination percentage.
- Association Yield was significantly correlated with leaf area index and plant height.
- Association Yield was not correlated with germination percentage.
- Association Height and leaf area index accounted for about 87% of yield variability.
- Observation Second-cut yields responded similarly but were lower than first-cut yields.
- Observation Seasonal water use averaged about 1.02 times pan evaporation.
- Intervention effect Combined treatment raised 1978 water-use efficiency from 15.6 to 43.9 kg/ha-cm.
- Intervention effect Combined treatment raised 1979 water-use efficiency from 19.1 to 51.2 kg/ha-cm.
