Calculate the plant population of maize sown in 5000 sq m area if the crop is sown in paired row of 40/80 cm and P-P 25 cm

Solution(By Examveda Team)

How to calculate plant population:
1. The plant population of any field is given by multiplying the plant's spacing by the spacing between the rows.
2. The total area of the field a square meters.
3. Divide 10,000 by the result of multiplying the between plant spacing and the between rows spacing as given:
$${\text{Plant population =}}$$    $$\frac{{{\text{area of field under cultivation }}\left( {{{\text{m}}^2}} \right)}}{{{\text{between plant spacing (m)}} \times {\text{between rows spacing row (m)}}}}$$
Here, Space between the plants is 40 and 80.
Taking average is 60 centimeter = 0.6 meter
Space between the rows = 25 centimeter = 0.25 meter
$$\eqalign{ & {\text{Plant population}} = \frac{{5,000}}{{0.60 \times 0.25}} \cr & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, = \frac{{5,000}}{{0.15}} \cr & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, = 33,333 \cr} $$
