Other claims from this paper (7)

Association Tempest lodged more than Tokyo, particularly in 1971.
Intervention effect Yield generally declined with each delay in sowing.
Intervention effect In 1971, yield increased with each increase in sowing rate.
Intervention effect In 1972, there was no yield difference due to sowing rate.
Intervention effect In 1973, yield increased to the third sowing rate and levelled out at the fourth.
Recommendation A sowing rate of over 34 kg/ha may be required to assure good yields each year.
Association Seed weight was not affected by sowing rate.

Observation Plant dry weight ranked 25°/20° above 30°/25° and 17°/12° with a 5°C daily range.
Observation Plant dry weight ranked 25°/15° above 30°/20° with a 10°C daily range.
Intervention effect At the same day temperature, nights 10°C cooler increased plant dry weight versus nights 5°C cooler.
Intervention effect Gradual and sudden temperature changes produced little difference in dry matter production.
Observation Outdoor plant dry weight was approximately that at 25°/20°.
Observation Seed yield was greatest at 25°/15° and 30°/20° and very small at 17°/12°.
Association Pod and seed number tended to increase with temperature under a 5°C daily range.
Observation Pod and seed numbers were nearly the same at 25°/15° and 30°/20°.
Intervention effect At the same day temperature, a 10°C daily range gave greater pod and seed numbers than a 5°C range.
Observation Outdoor pod and seed numbers were similar to 25°/20°.
Observation The 100-seed weight was greatest at 25°/20° and extremely small at 17°/12°.
Association N, K, TAC, and seed oil accumulation tracked dry matter accumulation across temperatures.
Association P accumulation tended to rise with temperature.
Observation At maturity, N, P, K and TAC accumulated mainly in seeds, Mg+Ca in pod shells, and Fe and Na in roots.
Association Seed Fe and oil concentration tended to rise with temperature.
Association Seed carbohydrate concentration tended to fall with temperature.
Association Palmitic, stearic and oleic acids tended to increase with temperature.
Association Larger seeds ripened outdoors or at 25°/20°, 25°/15°, or 30°/20° had higher germination percentage.
Recommendation The authors judged 25° to 30° day temperature with a 10°C daily range optimal for ripening performance.
