e0“Grain yield of sorghum, when grown at 16 plants m-2, increased from 9.2 to 11.5 t ha-1, and tiller mortality rate decreased from 0.7 to 0, if all individual tillers were systematically removed from the plant as soon as they appeared.”

Other claims from this paper (19)
- Observation Sorghum produced up to six tillers per plant at 2 plants m-2.
- Observation Rice produced up to 30 tillers per plant at 25 plants m-2.
- Observation Only primary tillers were observed in sorghum.
- Observation Secondary and tertiary tillers developed in rice.
- Association Sorghum tiller emergence rate was linearly related to main tiller leaf number.
- Association Rice tiller emergence rate was exponentially related to leaf number.
- Association Primary tiller emergence in rice was linearly related to leaf number, similarly to sorghum.
- Association Secondary tiller emergence probably followed leaf number of the mother primary tiller.
- Observation Leaf emergence dynamics on primary tillers matched the main tiller in both species.
- Association Sorghum tiller emergence ceased at leaf area index 0.6 across plant densities of 2 to 16 plants m-2.
- Observation Rice tiller emergence ceased at leaf area index 1.0 to 3.5.
- Observation Secondary and tertiary tillers ceased emerging later than primary tillers.
- Observation Tiller senescence systematically affected the youngest tillers in both species.
- Observation The apparent effect of tiller senescence on grain yield differed between sorghum and rice.
- Intervention effect Removing emerging sorghum tillers decreased tiller mortality rate from 0.7 to 0.
- Intervention effect Increasing water depth at mid-tillering decreased rice tiller mortality from 0.33 to 0.24.
- Intervention effect Transplanting younger rice seedlings decreased tiller mortality from 0.53 to 0.39.
- Intervention effect Reduced rice tiller mortality under these treatments did not affect grain yield.
- Observation Most tiller dynamic features were relatively consistent between the species under the studied conditions.
