Interaction effect of nitrogen form and planting density on plant growth and nutrient uptake in maize seedlings

Journal of Integrative Agriculture, 2019
High planting density is essential to increasing maize grain yield. However, single plants suffer from insufficient light under high planting density. Ammonium (NH4+) assimilation consumes less energy converted from radiation than nitrate (NO3−).

High nitrogen application rate and planting density reduce wheat grain yield by reducing filling rate of inferior grain in middle spikelets

Crop Journal, 2021
Excessive use of nitrogen fertilizer and high planting density reduce grain weight in wheat. However, the effects of high nitrogen and planting density on the filling of grain located in different positions of the wheat spikelet are unknown.

Grain Yield, Nitrogen Use Efficiency and Antioxidant Enzymes of Rice under Different Fertilizer N Inputs and Planting Density

Agronomy, 2022
Nitrogen fertilizer and planting density are key factors affecting rice yield and nitrogen utilization efficiency. There is still a need to optimize nitrogen fertilizer and planting density management for high yield.

Leaf angle: a target of genetic improvement in cereal crops tailored for high‐density planting

Plant Biotechnology Journal, 2022
Summary High‐density planting is an effective measure for increasing crop yield per unit land area. Leaf angle (LA) is a key trait of plant architecture and a target for genetic improvement of crops.

High planting density and leaf area index of masson pine forest reduce crown transmittance of photosynthetically active radiation

Global Ecology and Conservation, 2019
High planting density of Masson pine (Pinus massoniana) is perceived to have a major impact on timber production as well as understory biodiversity through changed leaf area index (LAI) and reduced understory photosynthetically active radiation (PAR ...

High Density Apple Planting Systems [PDF]

Journal of the Northeastern Agricultural Economics Council, 1974
Historically, the standard tree set in commercial apple orchards has been 27 trees per acre, planted on 40 foot centers. With this planting system trees tend to become quite large, requiring substantial amounts of labor for pruning, spraying and harvesting. The large amount of vegetative growth on these trees renders much of the innertree fruit bearing

Plant energetics and population density [PDF]

Nature, 1999
Enquist et al. 1 present data from 37 plant species showing that the use of resources by individual plants scales approximately as the 3/4 power of plant mass, as predicted previously from a model of resource use in fractal-like branching structures2.

Effect of Planting Density on Canopy Structure, Microenvironment, and Yields of Uniformly Sown Winter Wheat

Agronomy, 2023
A strong canopy structure is central to maximizing yield. The canopy microenvironment, which is related to crop growth and development, reflects changes in a crop’s microclimate. In this study, with the uniform sowing of winter wheat (Triticun aestivum L.

Effects of biochar application and nutrient fluctuation on the growth, and cadmium and nutrient uptake of Trifolium repens with different planting densities in Cd-contaminated soils

Frontiers in Plant Science, 2023
Biochar has been used to remediate contaminated-soil with heavy metals, however, less is known on how biochar interacts with planting density and nutrient fluctuation to affect the remediation.
