How to Calculate Plant Population

How to Calculate Plant Population.
Plant population refers to the number of plants per unit area of land.

Plant spacing, on the other hand, refers to the arrangement of plants on the area planted.

1. The Plant population of any field is calculated by multiplying “the between plants spacing within row and the spacing between the rows”.
2. The result is used to divide the total area of a land. For example:

Acre = 4,000 square meters
Hectare = 10,000 square meters

Examples:

If the between plant spacing of Tomatoes is 30cm and between row spacing is 90cm what is the plant population per hectare?

1. First convert cm to m
30cm =0.3m, 90cm =0.9

2. Multiply between plants spacing and the between rows spacing
0.3m x 0.9m = 0.27 sqm

3. Divide area of 1 hectare by 0.27sq m
10000 sq m / 0.27 sq m = 37037
4. Therefore Plant population of Tomatoes per ha is 37,037.

Note: if the spacing is in meter (m) you just multiple spacing within the row and between the rows.

For example
If plantain farm is spaced 3m by 3m, the planting population per hectare is 1,112 plantain stands (3×3 = 9. 10,000/9 = 1,112 per hectare).

If the land is an acre, the answer will be: 4,000/9 = 450 plantain suckers.
