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

Answer: Option A

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
$$\begin{array}{rl}& \text{Plant population}=\frac{5,000}{0.60\times 0.25}\\ & =\frac{5,000}{0.15}\\ & =33,333\end{array}$$
