Groundnut Cultivation and farming in india

Groundnut, also known as peanut or monkey nut, is a major oilseed crop of India and also an important agricultural export commodity. It is rich in protein, oil, minerals and vitamins. It is grown in an area of about 85 lakh hectares with the total production of 84 lakh tonnes. Groundnut cultivation in India is mainly confined to the states of Gujarat, Andhra Pradesh, Tamil Nadu, Karnataka, Maharashtra, Madhya Pradesh, Uttar Pradesh, Rajasthan, Punjab and Orissa.

Soil and Climate Requirements

Groundnut is best grown in well-drained sandy loam or sandy clay loam soil with a pH of 6.5-7.0 and high fertility. Deep well-drained soils with good aeration are ideal for groundnut. The crop cannot tolerate waterlogging, salinity or alkalinity. Optimum soil temperature for good germination of groundnut is 30°C. The low temperature at sowing delays germination and increases seed and seedling diseases.

Groundnut is a warm season crop that requires a long and warm growing season of about 120-150 days. It can be grown from sea level to an altitude of 1500 meters. The crop needs adequate moisture during the vegetative and flowering stages and dry weather during the pod development and maturity stages. The optimum rainfall requirement for groundnut is 500-600 mm per annum.


There are many varieties of groundnut available in India for different agro-climatic conditions and purposes. Some of the popular varieties are:

Land Preparation

The land should be prepared well in advance before sowing. The soil should be ploughed thoroughly to obtain a fine tilth and to remove weeds and stubbles. The field should be leveled and harrowed to make it uniform and smooth. The land should be given one or two ploughings followed by cross harrowing. The clods should be broken and the soil should be firmed by rolling or planking. The field should be divided into small plots of convenient size with proper drainage channels.


The sowing time of groundnut varies from region to region depending on the onset of monsoon and availability of moisture. In general, the sowing time is June-July for kharif season, October-November for rabi season and February-March for summer season. The sowing should be done when there is sufficient soil moisture for germination.

The seed rate depends on the variety, seed size, germination percentage and spacing. In general, the seed rate varies from 80-120 kg/ha for bold seeded varieties and 100-140 kg/ha for medium sized varieties. The seeds should be treated with fungicides such as thiram or captan @ 3 g/kg of seed to prevent seed borne diseases. The seeds should also be inoculated with Rhizobium culture @ 10 g/kg of seed to enhance nitrogen fixation.

The seeds should be sown at a depth of 5-6 cm in rows spaced at 30-45 cm apart depending on the variety and soil type. The spacing between plants within the row should be 10-15 cm. The seeds should be covered with fine soil and pressed lightly. The sowing should be done with a seed drill or by dibbling method.

Manure and Fertilizer Application

Groundnut requires a balanced supply of nutrients for optimum growth and yield. The application of manure and fertilizer should be based on soil test results and crop requirement. In general, the following doses of manure and fertilizer are recommended for groundnut:


Groundnut is a drought tolerant crop that can withstand short periods of water stress. However, irrigation is essential for obtaining higher yields and better quality. The irrigation requirement depends on the soil type, rainfall pattern, crop stage and climatic conditions. In general, the following irrigation schedule is recommended for groundnut:

The irrigation interval should be 10-15 days depending on the soil moisture status. The irrigation should be given through furrows or sprinklers to avoid wetting the foliage and pods. The irrigation should be stopped 10-15 days before harvest to facilitate easy digging and drying of pods.

Weed Control

Weeds are a major problem in groundnut cultivation as they compete with the crop for nutrients, water, space and light. They also harbor pests and diseases and reduce the quality and quantity of pods. Weed control is essential for obtaining higher yields and better quality. Weed control can be done by mechanical, cultural or chemical methods or by a combination of these methods.

Mechanical weed control involves manual weeding or hoeing with hand tools or power weeders. This method is effective but labor intensive and time consuming. It should be done at least twice during the crop growth, once at 25-30 days after sowing and again at 45-50 days after sowing.

Cultural weed control involves intercropping, mulching, crop rotation or mixed cropping with other crops that suppress weeds. Intercropping groundnut with crops such as maize, sorghum, pearl millet or small grains can reduce weed growth and increase land use efficiency. Mulching the soil with organic materials such as straw, leaves or crop residues can conserve soil moisture, prevent weed germination and improve soil fertility. Crop rotation with non-leguminous crops can break the weed cycle and reduce soil-borne diseases. Mixed cropping with crops such as sesame, sunflower, castor or cotton can provide additional income and diversify risk.

Chemical weed control involves the use of herbicides to kill or suppress weeds. Herbicides can be applied either pre-emergence or post-emergence depending on the type and stage of weeds. Pre-emergence herbicides are applied before the emergence of weeds and crop while post-emergence herbicides are applied after the emergence of weeds and crop. The choice and dose of herbicide depend on the weed spectrum, crop stage, soil type and climatic conditions. Some of the commonly used herbicides for groundnut are:

HerbicideDose (kg/ha)Time of applicationMode of action
Fluchloralin1.0-1.5Pre-sowingInhibits cell division in roots
Pendimethalin1.0-1.5Pre-emergenceInhibits cell division in roots
Alachlor1.0-1.5Pre-emergenceInhibits lipid synthesis in shoots
Butachlor1.0-1.5Pre-emergenceInhibits lipid synthesis in shoots

Pest and Disease Management

Groundnut is susceptible to various pests and diseases that can cause significant yield losses and quality deterioration. Pest and disease management is essential for obtaining higher yields and better quality. Pest and disease management can be done by integrated pest management (IPM) approach that involves the use of resistant varieties, cultural practices, biological control agents and chemical pesticides as per need.


Some of the major pests that attack groundnut are:


Some of the major diseases that affect groundnut are:


Groundnut is ready for harvest when the leaves turn yellow and start shedding. The maturity of the crop can also be judged by the color of the inner surface of the pod shell. The color changes from white to brown or black as the crop matures. The harvesting time varies from 90 to 150 days depending on the variety and season.

The harvesting of groundnut involves two operations: digging and threshing. Digging is done by using a spade or a plough to lift the plants along with the pods from the soil. The plants are then allowed to dry in the sun for 2-3 days. Threshing is done by beating the plants with a stick or a flail to separate the pods from the plants. The pods are then cleaned, graded and stored in gunny bags or jute sacks in a dry and well-ventilated place.

The yield of groundnut varies from 1 to 4 t/ha depending on the variety, season, soil type and management practices.
