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

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.

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.

Maize COMPACT PLANT 3 regulates plant architecture and facilitates high-density planting

The Plant Cell
Abstract Compact plant architecture allows more efficient light capture under higher planting density. Thus, it is a crucial strategy for improving crop yield, particularly in maize (Zea mays L.). Here, we isolated a maize gene, COMPACT PLANT 3 (CT3), regulating plant architecture, using map-based cloning.

PLUG PLANT FERTILIZATION AND PLANTING DENSITY AFFECT ONION PRODUCTIVITY IN SICILY

Acta Horticulturae, 2009
The aim of this study was to evaluate the effects of different planting density and different levels of plug plant fertilization on onion production in Sicily. Onion landrace ‘Bisacquino’ was sown in the first week of January 2006 in a unheated greenhouse in polystyrene plug trays.

PLANT-TO-PLANT VARIABILITY OF MAIZE PLANTS GROWN AT DIFFERENT DENSITIES

Canadian Journal of Plant Science, 1983
Development of plant-to-plant variability in plant height, flowering characteristics and grain yield was studied in two maize (Zea mays L.) hybrids grown over 2 yr at 62 000, 93 000 and 124 000 plants/ha. The purpose of the research was to provide fundamental data on patterns of interplant variability in maize, as a foundation for more applied studies

Plant Density and Soybean Yield

Crop Science, 1988
The spacial distribution of plants in a crop community is an important determinant of yield. However, the mechanisms responsible for the observed responses to changing plant density are not well understood. Field experiments utilizing a systematic design that made it possible to evaluate a wide range of plant densities in a single experiment were ...

Plant Density and Crop Yield

Applied Statistics, 1970
In investigations into the relationship between mean plant density and crop yield, an inverse power response curve has often been used. In this paper the theoretical properties of a family of these curves are examined, including situations where two or more such relationships are being compared. Methods of fitting these response models are given.
