Impacts of grass planting density and components on overland flow hydraulics and soil loss

Land Degradation & Development, 2022
Although abundant studies have confirmed the positive effect of vegetation on runoff and soil erosion reduction, few studies have clarified the effects of planting density and its components (aboveground parts and roots) on slope runoff and soil erosion ...

Density-dependent habitat selection in plants

Evolutionary Ecology, 1997
Pea plants exhibit density-dependent habitat selection as they grow. We split the root of a young pea (Pisum sativum L.) so that half grew in one pot and half in an adjacent pot. The rest of the plant remained intact. This is a ‘fence-sitter plant’. Each root-half was exposed either to no competition in its pot or to competitor plants sharing its pot ...

Density-dependent plant-soil feedbacks of two plant species affected by plant competition

Science of The Total Environment, 2022
Both plant-soil feedbacks (PSF) and plant competition drive plant community assembly, but their interactive effects have rarely been investigated, and the role of community composition in modulating these interactions is unknown. We conducted a fully reciprocal experiment with two plant species (Polygonum criopolitanum and Carex thunbergii) and their ...

Plant Density and Competition

2016
Crops respond to planting density modifying the characteristics of individual plants by changing the number and size of their organs. The density response can be described mathematically by the “Law of Reciprocal Yield”. Under very high density mortality of individuals occurs and is often more pronounced when environmental conditions are more suitable (

Mechanical properties of soybean plants under various plant densities

Crop and Pasture Science, 2020
Lodging can reduce grain yield and quality, especially in crops planted at high densities. Force analysis, which relates stem mechanical properties and morphological characteristics under high densities, was used to study lodging in soybean (Glycine max (L.) Merr.).

Density‐Structured Models for Plant Population Dynamics

The American Naturalist, 2011
Density-structured models are structured population models in which the state variable is the proportion of populations or sites in a small number of discrete density states. Although such models have rarely been used, they have the advantage that they are straightforward to parameterize, make few assumptions about population dynamics, and permit rapid

Optimisation of Planting Densities and Nitrogen Requirement for Bt Cotton under High Density Planting System

International Journal of Bio-resource and Stress Management, 2023
A field investigation was conducted at College farm, Professor Jayashankar Telangana State Agriculture University, Rajendranagar, Hyderabad, Telangana, India during kharif (July to January, 2021–22)to optimise the planting density and nitrogen dose on cotton yield and economics.

HIGH DENSITY PLANTING FOR SWEET CHERRY ORCHARDS

Acta Horticulturae, 2014
While a number of training systems are suitable for increasing sweet cherry planting density, the V and vertical axis systems are perhaps best suited to the task. New ideas regarding tree shape include short trees grown using dwarfing rootstocks like the Gisela® series.

Increasing yield, quality and profitability of winter oilseed rape (Brassica napus) under combinations of nutrient levels in fertiliser and planting density

Crop and Pasture Science, 2020
. Oilseed rape (Brassica napus L.) is a crucial source of edible oil and livestock feeding, and is a promising biofuel crop. The increasing demand for oilseed rape requires strategies to increase yield while retaining quality.

Density Determination in Plant Communities

Oikos, 1958
In an earlier paper by the former of the present authors (BOCHER, 1935), a modification of Raunkier's method of frequency determination was described. This modification made it possible to evaluate the density of shoots or individuals in plant communities.
