Introduction Groundnut (Arachis hypogaea L.) is an annual unpredictable legume cum oilseed crop which is also known as peanut, earthnut, monkeynut.

It has the 13th most important food crop and 4th most important oilseed crop of the world.

Groundnut seeds (kernels) contain 40-50% oil, 20-50 % protein and 10-20 % carbohydrate.

Groundnut seeds are a nutritional source of vitamin E, niacin, calcium, phosphorus, magnesium, zinc, iron, riboflavin, thiamine and potassium.

Groundnut kernels are consumed directly as raw, roasted or boiled kernels or oil extracted from the kernel is used as culinary oil.

It is also used as animal feed (oil pressings, seeds, green material and straw) and industrial raw material (oil cakes and fertilizer).

These multiple uses of groundnut plant makes it an excellent cash crop for domestic markets as well as for foreign trade in several developing and developed countries.

Cultivated groundnut originates from South America (Wiess 2000).

It is one of the most popular and universal crops cultivated in more than 100 countries in six continents .

Major groundnut growing countries are India (26%), China (19%) and Nigeria (11%).

Its cultivation is mostly confined to the tropical countries ranging from 40º N to 40º S.

Major groundnut producing countries are: China (40.1%), India (16.4%), Nigeria (8.2%), U.S.A (5.9%) and Indonesia (4.1%).

Among oilseeds crops in India, groundnut accounts for about 50% of area and 45% of oil production.

In India, about 75% of the groundnut area lies in a low to moderate rainfall zone (parts of peninsular region and western and central regions) with a short period of distribution (90-120 days).

Based on rainfall pattern, soil factors, diseases and pest situations, groundnut-growing area in India has been divided into five zones.

In India, most of the groundnut production is concentrated in five states viz. Gujarat, Andhra Pradesh, Tamil Nadu, Karnataka and Maharashtra.

These five states account for about 86% of the total area under peanut cultivation.

The remaining peanut producing area is scattered in the states of Madhya Pradesh, Uttar Pradesh, Rajasthan, Punjab, and Orissa.

Page 7: Groundnut seminar

Although the crop can be grown in all the seasons, it is grown mainly in rainy season (Kharif; June-September).

The kharif season accounts for about 80% of the total groundnut production.

In the Southern and Southeastern regions, groundnut is grown in rice fallows during post-rainy season (Rabi; October to March).

If irrigation facilities are available, groundnut can be grown during January to May as a spring or summer crop.

Monsoon variations cause major fluctuations in groundnut production in India.

Groundnut is grown in different cropping systems like sequential, multiple, and intercropping (Basu and Ghosh 1995).

What is yield gap and how to estimate it ?

Estimation of yield gap : The methodology developed by International Rice Research Institute (IRRI) have been followed to estimate the magnitudes of yield gap, wherein potential yield, potential farm yield and farmers’ yield are defined as yield obtained on research stations, demonstration plots and farmers’ fields, respectively (Gaddi et al., 2002).

Yield gap is the difference between potential yield and actual yield. The difference is explained by a number of constraints - biological, physical and socioeconomic.

All these constraints together account for the total yield gaps. It can be diveded into two parts viz., yield gap I and yield gap II.

Yield gap I = Potential yield - Potential farm yield

This yield gap arises from differences in environment that cannot be managed in the farmers’ fields.

Yield gap II: Potential farm yield - farmers’ yield

This gap reflects the effects of biological, soil and water, physiological, genetic and socio-economic constraints.

Page 12: Groundnut seminar

Production constraints in groundnut lack of varities for late sowing with drought tolerance.

Lack of alternate crops

Non availability efficient drills and harvesters

Imbalanced nutrition (poor soil fertility, non availability of organic manures, acid soils with low

organic matter content, low N and P and widespread Ca, Sulphur deficiency , very low fertilizer use.)

Delayed planting

Use of low seed rate and poor plant population

Use of poor quality seed and non-availability of quality seed

Poor water management

12

Page 13: Groundnut seminar

Cont….

Severe weed infestation

Moisture stress at more than one growth stage ( critical period)

Incidences of pest and diseases & non adoption of proper pest and disease management

Tikka and bud necrosis diseases.

Pests like Red hairy caterpillar, thrips, aphids etc

Due to terminal drought and harvesting of groundnut under low moisture condition causes yield losses.

Lack of exposure to productive technology packages

Widespread poverty

Table 33: Pests and disease management in groundnut Table 33: Pests and disease management in groundnut

Pests Management

Red hairy caterpillar Set up light traps and bonfire immediately after receipt of rains to attract and kill the moth.Deep ploughing in summer.Dig a deep, straight end trench and dust Carbonyl or Methyl parathion.Poison baits (5 kg rice bran + 1.0 kg jaggery + 500 ml Chloropyriphos) in the form of pellets around the field during evening hours

Aphids, Thrips Spray Monocrotophos (2 ml l-1 of water)

Leaf miner Quinalphos (2 ml l-1 of water)

Bud necrosis Early planting of kharif crop in June.Intercropping with millets Timely chemical control of thrips

Tikka Spray Mancozeb (2.0 g l-1) + Caebendazim (1.0 g l-1)

Use of medium sized seed material for sowing is highly profitable.

Sowing of groundnut in 1st fort night of June increases the pod yield.

FYM in combination with chemical fertilizers and micronutrients (like gypsum, lime, boron etc.) enhances the pod yield.

Pre plant incorporation of Fluchloralin fb Imazethapyr was found most economical.

Irrigating the crop at critical stages is economical.

Application of sand to deep black soil increases the pod yield.

Need to develop varities suitable for drought, pests, disease resistance.

INM, IWM, IPM modules to be prepared.

Need to develop suitable groundnut genotypes with fresh seed dormancy.

Improved agronomic practices.
