1. What is the Pea Seed Rate Calculator?

The Pea Seed Rate Calculator helps Indian farmers determine the optimal amount of pea seeds to sow per hectare based on target plant population and seed size (TGW). This ensures proper plant density for maximum yield.

2. How Does the Calculator Work?

The calculator uses the pea seed rate formula:

Where:

• Target Population — Desired number of plants per square meter
• TGW — Thousand Grain Weight in grams (measure of seed size)

Explanation: The formula calculates the seed quantity needed to achieve the target plant population considering seed size and germination rates.

3. Importance of Seed Rate Calculation

Details: Proper seed rate ensures optimal plant density, prevents overcrowding or sparse stands, and maximizes yield potential while minimizing seed costs.

4. Using the Calculator

Tips:

• For Indian conditions, typical target population ranges from 30-50 plants/m²
• TGW for peas typically ranges from 150-300g depending on variety
• Adjust for expected germination percentage (add 10-20% for safety margin)

5. Frequently Asked Questions (FAQ)

Q1: What is the ideal plant population for peas in India?
A: For most Indian varieties, 35-45 plants/m² is optimal, depending on soil fertility and irrigation.

Q2: How do I determine TGW for my seeds?
A: Weigh 1000 seeds from your batch using a precision scale, or consult your seed supplier for variety-specific TGW.

Q3: Should I adjust for germination percentage?
A: Yes, if your seeds have 80% germination, divide the calculated rate by 0.8 to get the actual sowing rate.

Q4: What's the typical seed rate for peas in India?
A: Most Indian pea varieties require 80-120 kg/ha depending on seed size and sowing method.

Q5: Does sowing method affect seed rate?
A: Yes, broadcasting requires 10-15% higher seed rate compared to line sowing for the same plant population.
