Density-Dependent Plant–Plant Interactions Triggered by Grazing [PDF]

open access: yesFrontiers in Plant Science, 2019
Plant species performance in rangelands highly depends on the effect of grazing and also on the occurrence of unpalatable benefactor species that can act as biotic refuges protecting neighboring plants from herbivores.

Plant energetics and population density” [PDF]

open access: yesNature, 1999
Enquist et al. 1 present an interesting analysis of the link between plant size, allometry and mortality. But I believe that their claim that it has a functional basis is misleading when it is scaled up to whole populations.

Determination of Plant Densities [PDF]

open access: yesNature, 1948
E. J. MACHIN1 appears to be unaware of the extensive study by G. E. Blackman2 on the relation between plant density and percentage absence. In a theoretical appendix to this paper, I have pointed out that the most efficient size of quadrat corresponds to about 20 per cent absence, or a product of quadrat size and plant density of about 1·6 (the ...

Effect of Spatial-Temporal Light Competition on Cotton Yield and Yield Distribution

open access: yesAgronomy, 2021
The photosynthetically active radiation (PAR) of crop canopy is highly related to yield formation, but how it relates to yield and yield distribution is not well understood.

Plant Density Estimation Using UAV Imagery and Deep Learning

open access: yesRemote Sensing, 2022
Plant density is a significant variable in crop growth. Plant density estimation by combining unmanned aerial vehicles (UAVs) and deep learning algorithms is a well-established procedure.

The Optimal Cultivar × Sowing Date × Plant Density for Grain Yield and Resource Use Efficiency of Summer Maize in the Northern Huang–Huai–Hai Plain of China

open access: yesAgriculture, 2021
In order to explore the optimal cultivar × sowing date × plant density for summer maize (Zea mays L.) in the Northern Huang–Huai–Hai (HHH) Plain of China, field experiments were conducted over two consecutive years (2018–2019) on a loam soil in the ...

Investigation of some production factors on yield and quality of dry beans

open access: yesInternational Journal of Horticultural Science, 2002
The correlation between plant density and yield average shows that the volume of yield increases in varieties of large and medium-size seeds up to a plant density of 285-400 thousand/ha, after which it declines.
