Subtopic: Precision Planters
Question Statement:
A precision maize planter has a vertical cell plate with 16 cells on its periphery. The drive wheel diameter is 64 cm and is geared to rotate at the same speed as the metering plate (speed ratio 1:1). The theoretical plant-to-plant spacing in the row (in cm) is:
Answer Key:
12.6
Step-by-Step Solution & Explanation
Ground distance travelled in one revolution of drive wheel $= \pi D = \pi \times 64 = 201.06\text{ cm}$. In one revolution, 16 seeds are dropped. Spacing between seeds $= \frac{201.06\text{ cm}}{16} = 12.57\text{ cm}$.
