Effects of Different Planting Densities on Photosynthesis in Maize Determined via Prompt Fluorescence, Delayed Fluorescence and P700 Signals

Plants, 2021
The mutual shading among individual field-grown maize plants resulting from high planting density inevitably reduces leaf photosynthesis, while regulating the photosynthetic transport chain has a strong impact on photosynthesis.

Changes in Radiation in Canopy and the Yield of Maize in Response to Planting Density and Irrigation amounts

Guan'gai paishui xuebao, 2021
【Objective】 Planting density and soil moisture combine to modulate plant growth and its ultimate yield. Taking maize as an example, this paper investigates the response of light radiation in the canopy and yield of the maize to different combinations of ...

Planting density and selection method in rice plant

Japanese Journal of Breeding, 1963
1. An investigation was made on the interaction between genotype and planting density in rice -plant, with the aim of contributing to the breeding of varieties adapted to high planting density. 2. The experiment consisted of two different forms of culture, i. e., early season culture and ordinary season culture.

Effects of planting date and plant density on yield and some physiological characteristics of single cross 550 hybrid maize as a second crop [PDF]

Caspian Journal of Environmental Sciences, 2022
Maize grain yield has a high potential and as planting late maturing cultivars is delayed for any reason, middle-aged maize cultivars can be used as an alternative plant.

Biomass conversion and expansion factors in Douglas-fir stands of different planting density: variation according to individual growth and prediction equations

Forest Systems, 2017
Aim of study: We built biomass expansion factors (BCEFs) from Douglas-fir felled trees planted with different planting densities to evaluate the differences according tree size and planting density.

Response of Water Radiation Utilization of Summer Maize to Planting Density and Genotypes in the North China Plain

Agronomy, 2022
Increasing the planting density of summer maize to improve the utilization efficiency of limited soil and water resources is an effective approach; however, how the leaf water-use efficiency (WUEL), yield, and RUE respond to planting density and ...

Increasing Planting Density and Optimizing Irrigation to Improve Maize Yield and Water-Use Efficiency in Northeast China

Agronomy
We investigated the effects of variety, planting density, and irrigation amount on grain yield, water-use efficiency (WUE), and evapotranspiration (ETc).

Episodic herbivory, plant density dependence, and stimulation of aboveground plant production [PDF]

Ecology and Evolution, 2020
AbstractHerbivory is a major energy transfer within ecosystems; an open question is under what circumstances it can stimulate aboveground seasonal primary production. Despite multiple field demonstrations, past theory considered herbivory as a continuous process and found stimulation of seasonal production to be unlikely.

Determining optimal mulching, planting density, and nitrogen application to increase maize grain yield and nitrogen translocation efficiency in Northwest China

BMC Plant Biology, 2020
Background The combination of mulch with N fertilizer application is a common agronomic technique used in the production of rainfed maize ( Zea mays L. ) to achieve higher yields under conditions of optimum planting density and adequate N supply. However,
