Agronomic Responses of Corn to Planting Date and Plant Density
Agronomy Journal, 2011Corn (Zea mays L.) grain yield is closely related to plant density and is typically maximized in the northern Corn Belt when planting occurs in late April. However, spring rainfall events often result in wet soil conditions that delay planting. From 2008 to 2010, experiments were conducted at two locations in southern Minnesota to determine whether the

Plant Density and Soybean Yield
Crop Science, 1988The 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 ...

Density‐Structured Models for Plant Population Dynamics
The American Naturalist, 2011Density-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

Crop Yield and Planting Density
Annals of Botany, 1983From 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 ...

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.

HIGH DENSITY PLANTING FOR SWEET CHERRY ORCHARDS
Acta Horticulturae, 2014While 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.

Applications of Density Sensor in Power Plant Desulphurization
2008 IEEE Pacific-Asia Workshop on Computational Intelligence and Industrial Application, 20087828 density sensor is a powerful tool in the desulphurization process in power plants. The characteristics, operation, electrical wiring, installation as well as the configuration software are introduced for this density sensor. It has been demonstrated that 7828 density sensor has met the comprehensive technological requirements in power plants.

Predictive control of a low density polyethylene plant
2001 European Control Conference (ECC), 2001The 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.

Flowering plant density and pollinator visitation in Senecio
Oecologia, 1983It 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
