Other claims from this paper (15)

Intervention effect Top growth rate in the vegetative period increased as planting density increased.
Intervention effect Top growth rate in the ear-filling period decreased rapidly, reaching its minimum at the highest planting density of about 100,000 plants/ha.
Observation The optimum leaf area index during ear-filling, where maximum TGR occurred, was about 3.0 in all years.
Observation The planting density giving the optimum LAI of about 3.0 was 73,000 plants/ha.
Observation Maximum ear growth rate in the latter half of ear-filling was obtained at 60,000 to 80,000 plants/ha.
Intervention effect Ear growth rate decreased at densities higher than the optimum range.
Association The decline in ear growth rate at higher planting density was promoted in the cold years of 1980 and 1981.
Intervention effect Incidence of barren plants increased with increasing planting density.
Association Barren plant incidence exceeded 20% when net assimilation rate in the latter half of ear-filling fell below 2.0 g/m2/day.
Intervention effect Ear dry-matter yield was highest at the medium planting density.
Intervention effect Stover and total dry-matter yields increased with increasing planting density.
Intervention effect Whole-plant dry-matter percentage did not differ significantly among planting densities in most years.
Intervention effect Ear/total ratio decreased with increasing planting density.
Intervention effect Maturity was delayed with increasing planting density.
Recommendation The optimum planting density for high yield and high quality of silage maize in the north-marginal area is about 70,000 to 75,000 plants/ha.

S. R. Winter; E. K. Thompson Agronomy Journal 1987. doi:10.2134/agronj1987.00021962007900010023x

Other claims from this paper (14)

Intervention effect Wheat grazed until 1 February had reduced leaf area index, biomass and mean tiller weight compared with grain-only wheat.
Intervention effect Wheat grazed until 1 February had reduced height and single-seed weight compared with grain-only wheat.
Intervention effect Grain yield, tiller density at heading and harvest index of wheat grazed until 1 February were not reduced compared with grain-only wheat.
Intervention effect Grazing until 6 March or later progressively reduced wheat LAI, biomass and tiller weight.
Intervention effect Grazing until 6 March or later progressively reduced wheat height and single-seed weight.
Intervention effect Heading of wheat was delayed by late grazing.
Intervention effect Wheat tiller density was not reduced unless grazing continued past 31 March.
Intervention effect Wheat harvest index was not reduced unless grazing continued past 17 March.
Mechanism Grazing until 6 March or later appeared to reduce wheat grain yield by limiting leaf area index and biomass in the spring.
Mechanism Removal of spikes by grazing cattle cannot be a primary cause of the loss in wheat grain yield.
Intervention effect Grazing past the period of initial elongation of the first internode delayed internode elongation in wheat.
Observation Growth and grain yield responses of wheat to grazing duration were basically the same across growing seasons.
Observation The grazed wheat did not reach Feekes stage 6 until about 1 April.
Recommendation The delay in reproductive development caused by continued grazing should be considered when grazing termination decisions are based on stage of development.
