1. What is Seed Size?

Seed size refers to the three-dimensional measurement of a seed, typically expressed in cubic millimeters (mm³). It's an important characteristic in agriculture and botany that affects germination, seedling vigor, and crop yield.

2. How Does the Calculator Work?

The calculator uses the simple volume formula:

Where:

• \( length \) — Longest dimension of the seed (mm)
• \( width \) — Middle dimension of the seed (mm)
• \( height \) — Shortest dimension of the seed (mm)

Explanation: The formula calculates the volume of the seed by multiplying its three principal dimensions.

3. Importance of Seed Size Measurement

Details: Seed size correlates with many important agricultural characteristics including germination rate, seedling survival, and eventual plant size. Larger seeds often have more stored nutrients for the developing seedling.

4. Using the Calculator

Tips: Measure each dimension accurately using calipers for precision. Enter values in millimeters. All values must be greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: How should I measure seed dimensions?
A: Use digital calipers for accuracy. Measure length (longest axis), width (middle axis), and height (shortest axis) at the seed's widest points.

Q2: Does seed shape affect the calculation?
A: The formula assumes a roughly rectangular shape. For irregular seeds, the result is an approximation of volume.

Q3: What's a typical seed size range?
A: Seed sizes vary greatly - from dust-like orchid seeds (0.01 mm³) to large coconuts (over 1,000,000 mm³).

Q4: Why is seed size important in agriculture?
A: Seed size affects planting depth, spacing requirements, and often correlates with early seedling vigor and establishment.

Q5: How many measurements should I take per seed?
A: For research purposes, measure at least 10 seeds from the same batch and calculate the average size.
