Groundnut (Arachis hypogaea) — Moongfali or Mungphali — is India's most important oilseed crop and a major source of edible oil, protein-rich cake and direct food. India is the world's second-largest groundnut producer after China, growing 6–7 million tonnes annually. Gujarat, Andhra Pradesh, Tamil Nadu, Karnataka, Rajasthan and Maharashtra lead production. For farmers in semi-arid regions, groundnut is a drought-tolerant, nitrogen-fixing cash crop that improves soil while generating income.

🌍 Climate & Soil Requirements
Climate और Soil
- Temperature: 25–30°C for germination and vegetative growth. 20–25°C for pod filling. Below 17°C slows growth. Above 35°C during pegging and pod development reduces pod set.
- Rainfall: 500–1,250mm. Excess rainfall during pod maturity causes aflatoxin contamination and quality loss. Well-distributed moderate rainfall is ideal — matches well with most semi-arid regions.
- Soil: Light sandy loam to loamy, well-drained. pH 6.0–6.5. Calcium-rich soil critical for pod development — groundnut pods develop directly in soil and need calcium. Heavy clay soils cause distorted pods and harvesting difficulty.
- Important: Avoid waterlogged soil. Groundnut cannot tolerate standing water even for 24 hours during pegging stage.
🗓️ Sowing Guide & Calendar
Sowing Guide और Calendar
| Season | Sowing Time | Harvest | Region |
|---|---|---|---|
| 🌧️ Kharif (main) | June–July | October–November | All India — 80% production |
| ❄️ Rabi | November–December | March–April | AP, TN, Karnataka (irrigated) |
| 🌸 Summer | February–March | May–June | AP, TN — with irrigation |
Sowing Method
- Seed preparation: Shell seeds 1–2 days before sowing. Treat shelled seeds with Thiram 3g + Carbendazim 1g per kg + Rhizobium culture 25g/kg. Rhizobium inoculation is free nitrogen — never skip this step.
- Spacing: 30×10 cm (bunch type), 45×15 cm (spreading/Virginia type). Correct spacing critical for pod development space.
- Seed rate: 80–100 kg/ha (bunch type), 100–120 kg/ha (Virginia type).
- Sowing depth: 4–6 cm. Too shallow = poor establishment. Too deep = poor emergence.
💧 Irrigation, Fertilizer & Earthing Up
Irrigation, Fertilizer और Earthing Up
Irrigation
| Stage | Irrigation Timing | Notes |
|---|---|---|
| Pegging (30–35 days) | 🔴 Critical — if no rain | Pegs penetrate soil here — drought causes total pod failure |
| Pod formation (45–60 days) | 🔴 Critical | Pod size determined here — consistent moisture essential |
| Pod filling (60–90 days) | High importance | Every 10–12 days in absence of rain |
| Maturity (last 2 weeks) | Stop irrigation | Dry conditions at maturity reduce aflatoxin risk |
Fertilizer (per hectare)
- N: Only 20 kg/ha basal — Rhizobium fixes remaining nitrogen. Excess nitrogen suppresses nodule formation.
- P: 40–60 kg/ha as SSP (single superphosphate) — SSP preferred over DAP as it also provides sulfur which increases oil content.
- K: 40–60 kg/ha — MOP at basal.
- Calcium (most important): Apply 400–500 kg/ha gypsum (calcium sulfate) at pegging stage by broadcasting around plants. This is the most critical nutrient specifically for groundnut pod filling and prevents empty pods.
- Earthing up: At 30–35 days — pile 5–8 cm soil around plant base. This covers pegs entering soil, improves pod development space and stabilizes plant. Critical practice — skip this = 20–30% fewer pods.
🐛 Pest & Disease Management
Pest और Disease Management
| Problem | Symptoms | Management |
|---|---|---|
| 🍄 Tikka Disease (Cercospora) | Brown circular spots with yellow halo on leaves — most common | Mancozeb 2.5g/L or Chlorothalonil spray every 10–15 days from 30 DAS |
| 🍄 Stem Rot (Sclerotium) | White fungal growth on stem base, yellowing, wilting | Trichoderma soil drench, Carbendazim dip at transplanting. Remove infected plants. |
| 🪲 White Grubs | Plants wilting in patches — roots eaten | Chlorpyrifos 20EC 5ml/L soil drench, Imidacloprid seed treatment |
| 🐛 Spodoptera (Leaf Eater) | Skeletonized leaves at night | Bt spray, Emamectin benzoate at early stage |
| ⚠️ Aflatoxin | Not visible — contaminates pods in wet storage | Prevention only: harvest at right time, dry to 8% moisture, store dry |
