- \(6.00\,kg/ha\)
- \(6.67\,kg/ha\)
- \(7.00\,kg/ha\)
- \(7.67\,kg/ha\)

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Seed rate means the quantity of seed required for sowing one hectare of land. In planters, seed rate depends mainly on row spacing, plant spacing, seed size and number of seeds dropped per hill.
Step 1: Cotton is generally planted at a specified row-to-row and plant-to-plant spacing.
Step 2: When spacing is fixed, the number of planting points per hectare can be estimated.
Step 3: Seed rate is then obtained by multiplying the number of planting points with the seed requirement per planting point.
Step 4: For the given cotton planter condition in the question, the calculated seed rate is: \[ 6.67\,kg/ha \]
Step 5: Therefore, the correct answer is: \[ \boxed{6.67\,kg/ha} \]
