How is plant density measured?
The actual plant density expressed in plants per square meter horizontal ground (plants m−2) was computed simply as the number of plants counted on the segments, divided by the product of the length of the segments and the row spacing.
What is meant by plant density?
Plant density is simply the number of individuals per unit ground area. In many circumstances, the identification of the individual is obvious. The unit of the population can clearly be identified as the individual plant in a crop of, for example, sunflowers (Helianthus annuus) or carrots (Daucus carota).
Why is plant density important?
Planting density modifies the photosynthetic rate and photosynthetic carbon assimilation capacity of different parts of leaves. This is so because planting density influences the nutritional status and light distribution characteristics of plants.
How do you measure seedling density?
Using a measuring tape, hip chain, or other device, measure the distance between several seedlings in a row(between 3 and 5), and divide by the number of seedlings.
What factors affect plant density?
Optimum plant density depends on size of the plant, elasticity, foraging area, nature of the plant, capacity to reach optimum leaf area at an early date and seed rate used. The factors affecting plant density are grouped into two as (a) genetic and (b) environment factors.
How do you calculate plant density per m2?
Calculating Spacing
- Divide 1m2 by the desired planting centres (this will be noted on the label) i.e. if you need to plant 30cm apart: 1m2 ÷ 0.3 = 3.33.
- Multiply 3.33 (top edge) x 3.33 (side edge) to get 11 plants per m2.
- Multiply this number by the number of square metres required to get the number of plants needed.
What happens if plant density is too high?
If the planting density is too high, plants may compete against each other, known as intra-specific competition. Under those conditions, the performance of individual plants becomes a limiting factor for maximum crop yield.
What is the optimum plant density?
Optimum plant density (i.e. the minimum population that produces maximum yield) and suitable plant arrangement per unit area allow crops to exploit resource optimally and produce high yields (Squire, 1993. (1993).
What is target plant density?
TARGET PLANT DENSITY Target plant densities should reflect the tillering capacity of the variety. For example, low tillering varieties (such as H45) should be sown at higher plant densities than high tillering vari- eties (such as Sunvale) to achieve target tiller numbers.
How do you calculate plant density per hectare?
A hectare is ten thousand rectangle metres in size in general. Divide ten thousand by the result of multiplying the plant spacing and row spacing among each other. plant populace= ten thousand ÷ among plant life spacing (m) × among rows spacing (m).
How do you calculate plant density per acre?
To calculate plant population per acre:
- Determine the area of the field in acres.
- Multiply the area of the field by the number of plants grown per stand.
- Divide the result by the product of space between plants in acres and space between rows in acres.
How do you calculate plant population in Ha?
The plant population per hectare was estimated using the following formula (Adebooye et al. 2006) : Pp = [10,000 m 2 9 number of plants per stand]/ [product of spacing], with Pp = plant population per hectare. …
How do you calculate plant population spacing?
The Plant population of any field is given by multiplying the between plants spacing with the spacing between the rows….
- First convert cm to m.
- Multiply between plants spacing and the between rows spacing.
- Divide area of 1 hectare by 0.27sq m.
How do you measure plant spread?
Plant spread is the maximum width of the plant as measured at its widest part from leaf tip to leaf tip at maturity.
How is agricultural density calculated?
To find the agricultural density, divide the area of farmland by the population of farmers in that area, giving you an average of land worked by each farmer.
