t0“Sudan grass (Sorghum sudanense (Piper) Stapf)”
e0“as the intrarow spacing between hills was increased from 15 cm to 20 and 25 cm, grain weight per panicle decreased by 11.3% and 25.7%, grain yield per hectare decreased by 6.6% and 15.7%, and harvest index decreased by 12.0% and 23.5%, respectively.”

Other claims from this paper (16)
- Intervention effect No cutting gave 52.3% higher grain yield than one cutting.
- Intervention effect No cutting gave 74.5% higher hay yield than one cutting.
- Intervention effect One cutting increased harvest index by 17.0% compared with no cutting.
- Intervention effect One cutting increased combined hay and green forage yield by 19.9%.
- Intervention effect The higher potassium rate gave maximum grain yield and yield components other than the stated exceptions.
- Intervention effect The potassium rates did not significantly differ in 1000 grain weight, hay yield, or combined hay and green forage yield.
- Intervention effect Spacing at 20 cm decreased grain weight per panicle by 11.3% from 15 cm.
- Intervention effect Spacing at 25 cm decreased grain weight per panicle by 25.7% from 15 cm.
- Intervention effect Spacing at 20 cm decreased grain yield by 6.6% from 15 cm.
- Intervention effect Spacing at 25 cm decreased grain yield by 15.7% from 15 cm.
- Intervention effect Spacing at 25 cm decreased harvest index by 23.5% from 15 cm.
- Observation The three factors interacted significantly for yield and yield components.
- Intervention effect Highest grain and hay yields occurred with no cutting, high potassium, and 15 or 20 cm spacing.
- Intervention effect At 15 or 20 cm spacing, one cutting plus high potassium sometimes matched no cutting plus low potassium for grain yield.
- Recommendation The authors advise against cutting Sudan grass when seed production is wanted.
- Recommendation For simultaneous green forage and grain, the authors recommend one cutting with 15 cm spacing and 120 kg ha-1 potassium.
