Growing Conditions

☀️
Sun: Full sun; requires 12-14 hours of daylight during growing season for optimal grain development
💧
Water: Requires flooded paddies during most of the growing season; maintain 5-10 cm water depth in fields during vegetative and reproductive stages. Needs approximately 1000-1500 mm total water (rainfall plus irrigation). Drain 7-10 days before harvest.
📏
Spacing: 6-8 inches between rows; 2-3 inches between plants within rows (typically direct seeded at 40-50 kg/hectare) inches
📅
Days to maturity: 120-140 days from sowing to harvest
🌱
Planting depth: Direct seeding: 2-3 cm deep; Transplanting: 20-25 days old seedlings planted 2-3 cm deep

Soil

Type: Well-draining clay loam to silty loam soil, slightly alkaline to neutral
pH: 6.5-7.5
Amendments:
Organic matter (farm compost or well-rotted manure) Nitrogen-rich fertilizers (urea or ammonium sulfate) Phosphorus and potassium fertilizers for balanced nutrition Zinc sulfate (in zinc-deficient soils)

Growth Stages

1

Germination & Early Seedling

7-10 days

Seeds absorb water and germinate; first shoot emerges within 5-7 days. Seedlings develop initial leaves and simple root system.

Maintain flooded conditions (pre-germinated seeds) or moist seedbed. Ensure adequate drainage to prevent damping off. Keep nursery beds weed-free.

2

Vegetative (Tillering)

30-45 days

Main stems develop side shoots (tillers); leaf number increases; plant establishes robust root system. This stage is critical for determining final plant structure and yield potential.

Maintain 5-10 cm water depth. Apply first dose of nitrogen fertilizer (40 kg N/hectare) at 15-20 days after transplanting. Second nitrogen dose at active tillering stage (30 days). Control weeds through timely weeding or herbicide application.

3

Panicle Initiation & Reproductive

20-30 days

Transition from vegetative to reproductive phase; panicles (flower heads) emerge from boot leaf; florets begin developing. Plant height stabilizes; focus shifts to grain development.

Apply third and final nitrogen dose (20 kg N/hectare). Maintain optimal water level and monitor for diseases (blast, brown spot). Ensure adequate potassium for grain filling.

4

Flowering & Grain Filling

25-35 days

Anthesis (flower opening) occurs; pollen is shed and fertilization happens. Grains fill with starch and nutrients; kernels gain weight and change color from green to golden yellow.

Maintain water level to support grain filling. Avoid water stress. Monitor for pest activity (stem borers, leaf folders). Continue disease surveillance.

5

Maturity & Harvest Ready

7-10 days

Grains achieve full maturity; color shifts to golden brown; moisture content drops to 18-20%. Stems become brittle and ready for cutting. Grain hardness reaches optimal level.

Begin draining fields 7-10 days before harvest. Reduce or stop irrigation. Monitor moisture content. Harvest when 80-90% of panicles have turned golden brown.

Companion Planting

Plan your garden →

Plant with:

Azolla (nitrogen-fixing aquatic fern in paddies) Fish (integrated rice-fish farming systems) Legumes (in rotation systems, not simultaneously)

Avoid planting near:

Continuous rice monoculture without rotation Plants requiring well-drained soils in a paddy environment

Common Pests

  • Use resistant varieties, apply neem oil spray, maintain proper water management, use pheromone traps, apply carbofuran or chlorpyrifos if severe

  • Remove affected leaves, spray with spinosad or lambda-cyhalothrin, encourage natural predators like spiders

  • Avoid excessive nitrogen, use insecticidal soap, apply imidacloprid or buprofezin, maintain field hygiene

  • Use blast-resistant varieties, apply fungicides (tricyclazole, azoxystrobin) at panicle initiation, improve field drainage, avoid dense planting

  • Use disease-free seeds, apply mancozeb or carbendazim fungicide, improve water management, remove crop residue

Harvest Tips

Harvest when 80-90% of panicles turn golden brown, typically 120-140 days after sowing. Moisture content should be 18-20% for optimal grain quality. Use mechanical combine harvesters or traditional sickles. Cut at the base of the stem, bundle, and cure for 7-10 days in the sun before threshing. Thresh immediately after curing to minimize grain damage. Winnow to separate chaff. Store at 12-13% moisture content in cool, dry conditions to preserve aroma and cooking quality.

Fun Facts

  • 🌱 Pusa 1121 was developed at IARI Delhi in 1999 and is named after the famous Indian Agricultural Research Institute's postal code; it revolutionized basmati rice production by combining the premium aromatic qualities of traditional basmati with significantly higher yields.
  • 🌱 The grain elongates by 40-50% upon cooking—a kernel that measures 8.5-9 mm before cooking can stretch to 12-13 mm, creating the characteristic long, slender appearance highly valued in international markets.
  • 🌱 India exports Pusa 1121 rice to over 150 countries worldwide, and it commands premium prices in international markets; the variety is so popular that it accounts for a significant portion of India's basmati rice export revenue, making it an economically important crop for Indian farmers.
