1. Introduction to Groundnut

Groundnut (Arachis hypogaea L.) belongs to the family Fabaceae (Leguminosae) and is one of the most widely cultivated oilseed crops in tropical and subtropical regions.

Unlike many other crops, groundnut develops its pods underground. After pollination, the flower stalk elongates and pushes the fertilized ovary into the soil, where pods develop. This unique characteristic makes groundnut one of the most fascinating crops in agriculture.

Groundnut seeds contain approximately 44–50% oil and 25–30% protein, making them one of the richest natural sources of edible oil and plant protein.

India is among the world's leading producers of groundnut, with Gujarat, Rajasthan, Andhra Pradesh, Tamil Nadu, Karnataka, Maharashtra, Madhya Pradesh, and Telangana being the major producing states.

Groundnut cultivation has become increasingly profitable due to rising demand from:

• Edible oil industries
• Snack food manufacturers
• Peanut butter producers
• Confectionery industries
• Export markets
• Livestock feed industries

Farmers prefer groundnut because it:

• Requires relatively low water compared to many field crops.
• Improves soil fertility through biological nitrogen fixation.
• Fits well into multiple cropping systems.
• Provides high economic returns under proper crop management.

2. Origin and History of Groundnut

Groundnut is believed to have originated in Brazil and neighboring regions of South America. Historical evidence suggests that wild relatives of groundnut existed in Brazil, Peru, Argentina, and surrounding areas thousands of years ago.

From South America, Portuguese traders introduced groundnut to Africa during the sixteenth century. Later, the crop spread to North America, Mexico, the Caribbean Islands, Southeast Asia, China, and India through maritime trade.

In India, groundnut first reached the eastern coast of the former Madras Presidency. Historical records indicate that commercial cultivation began in the Mysore region around 1800 AD, after which it rapidly spread across peninsular India.

Today, groundnut is cultivated in more than 100 countries, with India, China, Nigeria, Sudan, Myanmar, Argentina, Indonesia, Senegal, and the United States among the leading producers.

Over the last century, continuous breeding and research have resulted in improved varieties with higher yield potential, disease resistance, drought tolerance, and better oil quality.

Groundnut has evolved from a regional crop into one of the world's most important oilseed commodities, contributing significantly to food security, edible oil production, livestock nutrition, and international trade.

3. Importance of Groundnut Cultivation

Groundnut is often called the "Wonder Crop" because almost every part of the plant has economic value.

Major Reasons for Its Importance

1. Edible Oil Production

Groundnut seeds contain 44–50% high-quality edible oil, which is widely used for cooking due to its pleasant flavor and excellent shelf life.

11. Land Preparation for Groundnut Cultivation

Proper land preparation is one of the most important steps in successful groundnut cultivation. Since groundnut produces pods beneath the soil surface, the soil should be loose, friable, and well-drained to allow easy penetration of pegs and proper pod development. Hard or compact soils restrict peg penetration, resulting in poor pod formation and reduced yields.

Objectives of Land Preparation

• Create a fine seedbed for uniform germination.
• Improve soil aeration and water infiltration.
• Eliminate perennial weeds.
• Enhance root development.
• Facilitate easy peg penetration.
• Prevent waterlogging.

Primary Tillage

Carry out one deep ploughing using a mouldboard plough or disc plough during summer (April–May). Deep ploughing exposes harmful insects, pupae, nematodes, and weed seeds to sunlight, reducing their population before sowing.

Secondary Tillage

After receiving pre-monsoon showers or irrigation, perform two to three harrowings or cultivator operations until the soil becomes fine and well-pulverized.

The final seedbed should be:

• Loose
• Well-levelled
• Free from weeds
• Well-drained
• Free from large soil clods

Organic Matter Incorporation

Incorporate well-decomposed Farmyard Manure (FYM) or compost during the final land preparation.

Recommended dose:

• FYM: 10–15 tonnes/ha
• Per Acre: 4–6 tonnes

Organic matter improves:

• Soil structure
• Water holding capacity
• Microbial activity
• Root growth
• Nutrient availability

Drainage Management

Groundnut is extremely sensitive to waterlogging. Construct drainage channels before sowing, especially in heavy rainfall areas.

12. Seed Selection

Seed quality directly influences germination, plant population, disease incidence, and final yield.

Always select certified, healthy, and genetically pure seeds.

Characteristics of Good Seed

• High germination (>85%)
• Uniform size
• Bold kernels
• Disease-free
• Insect-free
• Well-developed seed coat
• True to variety

Avoid:

• Broken kernels
• Shrivelled seeds
• Moldy seeds
• Damaged seeds
• Immature pods

Shelling of Pods

Groundnut pods should be shelled only 2–3 days before sowing.

Early shelling may reduce seed viability due to moisture loss and mechanical damage.

Use only fully mature pods for shelling.

13. Recommended Groundnut Varieties

Selection of suitable varieties depends on climate, rainfall, soil type, irrigation facilities, and market demand.

21. Nutrient Management in Groundnut Cultivation

Proper nutrient management is the foundation of successful groundnut production. Since groundnut is a leguminous crop, it has the ability to fix atmospheric nitrogen through Rhizobium bacteria. However, for optimum growth and high yields, balanced nutrition is essential.

Groundnut requires both macronutrients (Nitrogen, Phosphorus, Potassium, Calcium, Sulphur, Magnesium) and micronutrients (Zinc, Boron, Iron, Manganese, Copper, Molybdenum) at different growth stages. A deficiency of any one nutrient can lead to poor flowering, inadequate peg formation, empty pods, low kernel weight, and reduced oil content.

Major Nutrient Functions

• Nitrogen (N): Promotes vegetative growth and leaf development.
• Phosphorus (P): Encourages root growth, flowering, and early maturity.
• Potassium (K): Improves drought tolerance, disease resistance, and seed quality.
• Calcium (Ca): Essential for peg penetration, pod filling, and kernel development.
• Sulphur (S): Required for oil formation and protein synthesis.
• Magnesium (Mg): Vital for chlorophyll production and photosynthesis.

Balanced fertilization improves:

• Pod size
• Kernel filling
• Oil percentage
• Shelling percentage
• Drought tolerance
• Disease resistance
• Market quality

22. Recommended Fertilizer Dose

Key Takeaway

Balanced nutrition is the foundation of high-yielding groundnut cultivation. Farmers who combine soil testing, timely fertilizer application, gypsum at flowering, micronutrient correction, and organic matter incorporation consistently achieve higher pod yield, better kernel quality, and improved oil recovery.

31. Weed Management in Groundnut Cultivation

Weeds are one of the major constraints in groundnut production, especially during the early growth stages. Since groundnut is a slow-growing crop during its initial 30–45 days, weeds compete aggressively for nutrients, moisture, sunlight, and space. If not controlled properly, weed infestation can reduce pod yield by 30–70%, depending on the weed species and severity of infestation.

The critical period of weed competition in groundnut is 15–45 Days After Sowing (DAS). Maintaining a weed-free field during this period is essential for maximizing yield.

Common Weeds in Groundnut Fields

Grassy Weeds

• Echinochloa spp.
• Cynodon dactylon (Bermuda Grass)
• Dactyloctenium aegyptium
• Digitaria spp.

Broadleaf Weeds

• Amaranthus viridis
• Trianthema portulacastrum
• Euphorbia hirta
• Portulaca oleracea

Sedges

• Cyperus rotundus
• Cyperus iria

Integrated Weed Management (IWM)

The best approach combines cultural, mechanical, and chemical methods.

Cultural Practices

• Use certified weed-free seed.
• Follow crop rotation.
• Maintain optimum plant population.
• Prepare a clean seedbed.
• Remove weeds from field bunds.
• Use organic mulch where feasible.

Mechanical Control

• First hand weeding: 20–25 DAS
• Second hand weeding: 40–45 DAS
• Light earthing-up after the second weeding improves peg penetration and suppresses new weed growth.

Mechanical weeding is especially effective in small and medium-sized farms.

32. Herbicide Recommendations

Chemical weed control is particularly useful where labour is scarce or costly. Herbicides should be selected based on weed flora and applied according to label recommendations.

Pre-Plant Incorporation (PPI)

Fluchloralin

• Apply before sowing and incorporate into the soil.
• Controls annual grasses and many broadleaf weeds.

Pre-Emergence (0–3 DAS)

Pendimethalin

• Apply immediately after sowing on moist soil.
• Provides broad-spectrum control of annual grasses and broadleaf weeds.

Early Post-Emergence

Depending on the weed spectrum and the registered products available in your region, suitable post-emergence herbicides may be used following label recommendations and local agricultural university advisories.

Best Weed Management Schedule

33. Irrigation Management

Groundnut is moderately drought-tolerant but responds exceptionally well to timely irrigation. Both moisture stress and waterlogging adversely affect growth and yield.

Proper irrigation management ensures:

• Uniform germination
• Better flowering
• Successful peg penetration
• Proper pod filling
• Higher oil content
• Increased kernel weight

The crop generally requires 450–700 mm of water, depending on soil type, climate, and season.

Irrigation Frequency

Sandy Soils

• Every 5–7 days during summer.
• Every 7–10 days during winter.

Loamy Soils

• Every 7–10 days during summer.
• Every 10–12 days during winter.

Heavy Soils

• Irrigate only when required based on soil moisture.

Avoid over-irrigation, as excessive moisture encourages fungal diseases and reduces oxygen availability in the root zone.

34. Critical Irrigation Stages

Groundnut is highly sensitive to moisture stress during specific growth stages.

1. Germination (0–7 DAS)

Adequate soil moisture ensures rapid and uniform emergence.

2. Flower Initiation (25–35 DAS)

Water stress during flowering reduces the number of flowers and affects pod production.

3. Peg Formation (35–50 DAS)

This is the most critical stage. Moist soil is essential for pegs to penetrate the soil successfully.

4. Pod Development (50–80 DAS)

Insufficient moisture leads to poor pod filling and lower kernel weight.

5. Seed Filling (80–100 DAS)

Adequate moisture improves oil accumulation and seed quality.

Irrigation During Harvest

Stop irrigation 10–15 days before harvesting to:

• Improve pod maturity.
• Facilitate easier digging.
• Reduce pod losses.
• Prevent fungal infections.

35. Water Management and Drainage

Water management is not only about irrigation but also about avoiding excess water.

Best Practices

• Prepare raised beds in poorly drained soils.
• Maintain drainage channels between plots.
• Remove standing water immediately after heavy rainfall.
• Irrigate based on soil moisture rather than fixed intervals.

Water Conservation Techniques

• Mulching
• Drip irrigation
• Rainwater harvesting
• Laser land levelling
• Conservation tillage

These methods improve water use efficiency and reduce irrigation costs.

36. Intercropping Systems

Groundnut is highly suitable for intercropping because of its compact growth habit and nitrogen-fixing ability.

Recommended Intercrops
