How to calculate Plant Population per hectare

 How to calculate Plant Population per hectare

1. The Plant population of any field is given by multiplying the between plants spacing with the spacing between the rows.
2. The total area of a hectare is 10000 square metres.
3. Divide 10000 by the result of multiplying the between plant spacing and the between rows spacing as given in as shown below

Plant population = 10 000
______________________________
between plants spacing (m)x between rows spacing row (m)

An example
If the between plant spacing of soybean is 5 cm and between row spacing is 45 cm what is the plant population per hectare?

1. First convert cm to m
45cm =0.45m, 5 cm =0.05
2. Multiply between plants spacing and the between rows spacing
0.45m x 0.05m = 0.0225 sqm
3. Divide area of 1 hectare by 0.0225 sq m 

10000 sq m / 0.0225 sq m = 4,44,444 

4. Therefore Plant population of soybean per ha is 4,44,444
