R. W. Willey; R. Holliday The Journal of Agricultural Science 1971. doi:10.1017/s0021859600064522

Other claims from this paper (10)

Intervention effect Ear development shading decreased grains per ear.
Intervention effect Grain filling shading reduced grain yield.
Intervention effect Grain filling shading decreased grain size.
Intervention effect Thinning at anthesis did not increase yield per remaining ear.
Observation Earlier thinning showed competition progressively reduced ear capacity.
Association Higher population competition accelerated reduction in ear potential.
Association Grains per ear were suggested to most influence yield decline above optimum population.
Association Grain yield per area closely related to grains per area across population response curves.
Mechanism High population yield decline was suggested to result from fewer grains per area.
Mechanism Fewer grains per area at high density were attributed more to reduced late dry matter production than unfavorable partitioning.
