planting density

As planting densities increase so does the proportion of far red light in the canopy.

Over the past few decades, major increases in grain yield have come largely through increasing planting densities.

The maximum authorized planting density is 3,000 vines/ha.

A compromise between planting density for maximizing flower production, weed control and ease of fruit collection may be essential.

This means increasing the planting density (i.e., the numbers of plants per hectare) in an already growing forest stand."

Planting density affects multiple aspects of maize.

Because the two genotypes were phenologically different, planting density optima are probably different for each population.

Bambara groundnut is mainly cultivated as intercrop, however the planting density varies between 6 to 29 plants per square meter.

The planting density is 9 000 vines per hectare using a double Guyot training and the average age of the vines is 30 years.

A minimum planting density of 9,000 vines per hectare and a minium grape maturity of 11.5 per cent potential alcohol is required.

Controlling the disease involves eliminating conducive conditions as much as possible by altering planting density and carefully timing applications and rates of nitrogen.

The minimum planting density is 2,000 vines/ha, whether planted as low individual vines (en vaso) or on trellises (en espaldera).

In the UK, there is a nationwide experiment for silvopastoral systems in which a number of tree species and planting densities are being studied over a range of sites.

Planting density per hectare ranges from 5,000 vines per hectare in the older vineyards of the Estate to 7,000 vines per hectare in the Bellaria vineyards.

Hydraulic structures (inlet and outlet zones) should be designed to ensure adequate pre-treatment and prevent large nutrient 'spikes' Landscape design, using appropriate plant species and planting density are also necessary.

"From the beginning, in late 1996, Paul was involved in all aspects of planning, from the clones of merlot to plant, to planting density, to equipment selection," Mr. Olsen-Harbich said.

The newer vineyards are planted on trellises (en espaldera) to allow mechanisation of the vineyard activities, at authorised planting densities of between 2,000 and 4,500 vines/ha depending on the terrain.

Hemp, because of its height, dense foliage and its high planting density as a crop, is a very effective and long used method of killing tough weeds in farming by minimizing the pool of weed seeds of the soil.

In almost every case, however, the wineries ultimately benefited from the disaster by rectifying errors they had made and by taking advantage of the latest research on new grape clones, planting density and the compatibility between rootstocks and the vines grafted to them.

At the Sonoma vineyard, the estate utilizes traditional Mediterranean viticultural practices, such as a vertical trellis for the vines, the choice of rootstocks that are more resistant to phylloxera and a planting density of 2 m x 1m (2,000 vines per acre).

Plant diseases can also be partially controlled by use of pesticides, and by cultivation practices such as crop rotation, tillage, planting density, purchase of disease-free seeds and cleaning of equipment, but plant varieties with inherent (genetically determined) disease resistance are generally the first choice for disease control.
