Intervention effect Selection only for early flowering significantly changed virtually every trait measured in corn.
Intervention effect Selection only for early flowering increased corn yield by 1.00 q/ha per cycle.
Intervention effect Selection only for early flowering increased stalk breakage by 2.8% per cycle in corn.
Intervention effect Selection only for early flowering decreased plant height by 7.2 cm per cycle in corn.
Intervention effect Selection only for early flowering decreased ear height by 5.2 cm per cycle in corn.
Intervention effect Selection only for early flowering reduced days to flowering by 1.8 days per cycle in corn.
Intervention effect Selection only for early flowering reduced silk delay by 0.3 days per cycle in corn.
Recommendation Selecting materials for adaptation to high plant densities may be possible by the silk delay method in corn.
Association Early flowering cycles had a distinct yield advantage in a cool, short season, in a maturity-influenced cycle-by-year interaction.

Competition of Sicklepod with Soybeans

Donald L. Thurlow; Gale A. Buchanan Weed Science 1972. doi:10.1017/s0043174500035906

Other claims from this paper (6)

Association Weed density was a linear function of soybean yield over 0 to 15 weeds/m2 (sicklepod competition).
Association Densities of 7.7 weeds/m2 reduced soybean yield by 19 to 32% and 34 to 35% on the two soils.
Association The weight of weeds at harvest was inversely correlated with soybean yield.
Intervention effect Sicklepod was more competitive when grown 15 to 30 cm from the drill than in the drill.
Intervention effect Soybean yields were reduced in some instances when sicklepod competed for as little as 4 weeks.
Intervention effect Weed removal at 2 to 4 weeks after soybean emergence gave maximum soybean yield with no further weed removal needed.
