Peanut Cultivation: A Complete Guide to Growing Groundnut Successfully
Peanut, also known as groundnut (Arachis hypogaea), is one of the most important oilseed and food crops grown across tropical and subtropical regions. In countries like India, peanuts play a vital role in farmers’ income, edible oil production, and nutrition. Peanuts are valued for their high content of protein, healthy fats, vitamins, and minerals.
Successful peanut cultivation requires proper knowledge of climate, soil, varieties, and crop management practices. This blog provides a complete guide to peanut cultivation, from land preparation to harvesting, along with frequently asked questions.
Importance of Peanut Cultivation
Peanuts are used in multiple ways—direct consumption, peanut butter, oil extraction, animal feed, and confectionery products. The crop also improves soil fertility by fixing atmospheric nitrogen through root nodules, making it beneficial in crop rotation systems.
Due to its wide adaptability and good market demand, peanut cultivation is highly profitable when managed properly.
Peanut is a warm-season crop and grows best in a tropical climate.
Temperature: Ideal temperature ranges between 20°C and 30°C
Rainfall: Requires 500–1,000 mm of well-distributed rainfall
Sunlight: Full sunlight is essential for healthy growth and pod development
Excessive rainfall or prolonged cloudy weather can lead to fungal diseases and poor pod formation.
Peanuts prefer light, well-drained soils for proper pod development.
Best soil types: Sandy loam or loamy soil
Drainage: Good drainage is essential to avoid waterlogging
Proper land preparation is crucial for high yields.
Plough the field 2–3 times to achieve a fine tilth
Remove weeds, stones, and crop residues
Level the land to ensure uniform irrigation
Raised beds or ridges are often recommended in areas prone to water stagnation.
Improved Varieties of Peanut
Selection of suitable varieties depends on region, season, and purpose.
Spanish types: Short duration, small seeds (e.g., JL 24)
Virginia types: Large seeds, spreading habit
Runner types: High yield and oil content
Farmers should choose certified seeds recommended by local agricultural universities.
Kharif season: June to July (with onset of monsoon)
Rabi/Summer season: November to December (under irrigation)
Seeds should be treated with fungicides and Rhizobium culture before sowing to prevent diseases and enhance nitrogen fixation.
Spanish varieties: 100–125 kg/ha
Virginia varieties: 120–150 kg/ha
Use bold, healthy, and disease-free kernels for better germination.
Although peanuts fix nitrogen, balanced fertilization improves yield.
Basal dose (per hectare):
Calcium and gypsum: Application of gypsum at flowering stage improves pod filling and seed quality.
Peanuts require timely irrigation, especially during critical growth stages.
Avoid over-irrigation as it can cause root rot and fungal diseases. Drip irrigation is an efficient option for water-saving and higher productivity.
Weeds compete with peanuts for nutrients and water, especially during early growth.
Manual weeding: 2–3 weedings at 15–45 days after sowing
Mulching: Reduces weed growth and conserves moisture
Herbicides: Pre-emergence herbicides can be used as recommended
Pest and Disease Management
Integrated Pest Management (IPM), including crop rotation, resistant varieties, and timely spraying of recommended pesticides, helps reduce losses.
Peanuts are ready for harvest in 100–130 days, depending on the variety.
Inner shell veins turn dark
Harvesting should be done carefully to avoid pod losses. After harvesting, plants are dried for a few days, and pods are separated.
Rainfed conditions: 1.0–1.5 tons/ha
Irrigated conditions: 2.0–3.0 tons/ha
Proper crop management can significantly improve yield and profitability.
