Nutritional Value

• Rich in soluble fiber (β-glucan) – helps lower cholesterol
• Good source of protein, iron, zinc, manganese, and B vitamins

• Used for oatmeal, porridge, cookies, livestock feed, silage

Climate Requirement

• Type: Cool-season crop
• Optimum temperature: 15–25°C
• Tolerates light frost, but not extreme heat
• Grown mainly in Rabi season in India (Nov–March)

Soil Requirement

• Prefers well-drained loamy soils
• pH range: 6.0–7.5
• Can tolerate slightly acidic soils
• Requires good moisture (not suitable for drought-prone areas)

Major Oat Growing Regions

• World: Russia, Canada, USA, Poland, Australia, Finland
• India: Punjab, Haryana, Uttar Pradesh, Madhya Pradesh, Rajasthan

Seed Rate & Sowing

• Seed rate: 80–100 kg/ha (grain purpose) | 100–120 kg/ha (fodder purpose)
• Sowing depth: 2–3 cm
• Row spacing: 25–30 cm

Fertilizer Requirement

• General recommendation: 80:40:40 NPK kg/ha
• Apply ½ N + full P & K as basal; rest of N in 2 splits (tillering & stem elongation)
• Oats respond well to organic manure

Forage & Fodder Use

• Excellent for green fodder, silage, hay
• Cut at 50% flowering stage for best nutritive value
• Fodder yield: 350–400 q/ha (green fodder)
• Grain yield: 20–30 q/ha under good management

Diseases & Pests

• Diseases:
  • Leaf rust (Puccinia coronata)
  • Crown rust
  • Smut
  • Helminthosporium leaf spot
• Pests: Aphids, stem fly, armyworms
• Management: Resistant varieties, crop rotation, fungicides (Mancozeb, Propiconazole)

Weed Management

• Pre-emergence herbicide: Pendimethalin @ 0.75–1.0 kg/ha
• Early intercultural weeding

Harvesting & Yield

• For grain: Harvest when panicles turn yellow & grain moisture is 14–15%
• For fodder: Harvest at 50% flowering stage
• Grain yield: 20–30 q/ha
• Green fodder yield: 350–400 q/ha

 Storage

• Dry grains to <12% moisture
• Store in cool, dry godowns with aeration
• Treat with neem leaves or fumigation against pests
