Required plant population of gram may be obtained by using a seed rate of (kg/ha)

Answer: Option B

To find the seed rate per hectare, we have to divide the number of seeds needed by the number of seeds per kg, and multiplying this times the size of the field in hectares will give the total amount of seeds required.
The required plant population of a gram may be obtained by using a seed rate of 75 - 100 kg/ha.
