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 ...

Predictive control of a low density polyethylene plant

2001 European Control Conference (ECC), 2001
The paper aims to present the possibilities of controlling a multizone tubular reactor for producing low-density polyethylene using the Model Based Predictive Control (MBPC) strategy, specifically Extended Predictive Self-Adaptive Control (EPSAC) approach.

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.

Crop Yield and Planting Density

Annals of Botany, 1983
From the established responses of plants to photosynthetic activity and to the availability of nutrients in the soil, a crop yield : planting density response equation is derived with parameters that are of biological significance. The relationship between crop yield, Y (kg m~2) and planting density, p (number of plants m~2), is of considerable ...

Flowering plant density and pollinator visitation in Senecio

Oecologia, 1983
It has commonly been assumed that pollinator energy intake increases with flowering plant density, and visitation to flowers should therefore be higher in denser stands. I therefore investigated the relationship between flight distance and flight time for bumblebees and butterflies foraging on Senecio integerrimus and S. crassulus in the Colorado Rocky

Plant Protoplast Enucleation by Density Gradient Centrifugation

2003
A number of different methods have been developed for the enucleation of cells, particularly mammalian cells. Centrifugation of cells adhering to a surface may lead to the nucleus being drawn out from the cytoplasm, resulting in the formation of an enucleated cell or cytoplast and a nucleus surrounded by a thin layer of cytoplasm bounded by a plasma ...
