1. Climate Requirements

● Spinach grows well in cool and temperate climates.
● Suitable sowing seasons: Summer and Rabi.
● Can be grown throughout the year under temperate climate.
● Extreme heat reduces leaf quality and increases bolting.

2. Soil Requirements

● Prefers well-drained loamy or silt-loam soil rich in organic matter.
● Soil should be soft and fertile for quicker leaf production.
● Soil health and water pH directly affect leaf color and yield.
● Avoid waterlogging to prevent root diseases.

3. Sowing & Spacing

● Best sowing months:

• January–February
• September–November
• Seed rate:
• Summer: 15–20 kg/ha
• Winter: 10–15 kg/ha
• Spacing: 20–30 cm between lines
• Sow seeds in moist, fine, well-prepared soil.
  

4. Manure & Fertilizer Management

● Apply 30–40 MT/ha FYM (Farm Yard Manure).
● Recommended fertilizer dose: NPK 100 : 50 : 50 kg/ha.
● Provide micronutrients as per soil test for deep green leaves.

5. Irrigation

● Provide 8–10 irrigations during the crop cycle.
● Irrigation interval:

• Summer: every 6–7 days
• Winter: every 10–15 days
• Avoid stagnant water to prevent fungal diseases.
  

6. Crop Duration

● Total duration: 120–130 days.
● Allows 6–8 cuttings of fresh leaves.

7. Factors Affecting

● High temperature
● Heavy rainfall
● Climatic fluctuations
● Poor soil health
● Improper water pH
● Pest and insect attack
