Eggplants Water Requirement - typically require about 1.5–3 liters of water per day per plant

Eggplants typically require about 1.5–3 liters of water per day per plant, which adds up to approximately 45–90 liters per month and 540–1,080 liters per year.

Here’s a detailed breakdown based on growth stage, climate, and soil conditions:

🍆 Daily Water Requirement

  • Seedlings (0–1 month): 0.5–1 liter/day to maintain moist soil.

  • Growing plants (1–3 months): 1.5–2 liters/day as root systems develop.

  • Mature fruiting plants (3+ months): 2–3 liters/day during peak production.

Eggplants need about 1–2 inches of water per week, which translates to roughly 0.2857 inches/day. This equals around 1.5–3 liters/day, depending on soil type and weather.

📅 Monthly Water Requirement

  • Average range: 45–90 liters/month per plant.

  • Seasonal variation:

    • Hot/dry season: Up to 100 liters/month.

    • Cooler months or rainy season: May drop to 30–40 liters/month.

📈 Annual Water Requirement

  • Estimated total: 540–1,080 liters/year per plant.

  • Factors influencing this:

    • Local rainfall and humidity

    • Soil drainage and retention

    • Irrigation method (drip vs overhead)

    • Planting density and crop duration

💧 Irrigation Tips for Eggplant

  • Water deeply to encourage root growth up to 6 inches into the soil.

  • Avoid shallow, frequent watering—it leads to weak roots and yellowing leaves.

  • Best times to water: early morning or evening to reduce evaporation.

  • Monitor for signs of overwatering (fungus, wilting) or underwatering (dry soil, drooping leaves).
