Groundnut is a dual-purpose crop. It can be cultivated as an oil crop as well as a protein or a pulse or leguminous crop. Although groundnut is a leguminous crop, it is mainly grown for its oil, used as for the production of animal feeds, for making soup in Africa, eating locally in combination with maize, garri or bread

what does groundnut seed contain?

The seed called nut contains about 40 – 55% oil, 30% protein and 18% carbohydrate. Industrial products of groundnut include:
(i) Groundnut cake.
(ii) Groundnut oil.

(iii) Groundnut butter.

Land Preparation for the cultivation of groundnut

The land is cleared, stumping i done and land can also be prepared mechanically by ploughing, harrowing and ridging.

Varieties/Cultivars of groundnut

Bunch or erect type, creeping type, Kano local, Kano 50 and castle carry.

Climatic requirement for the cultivation of groundnut

Groundnut requires a temperature of 25C – 30C, rainfall of 70 – 100cm per annum.

Maturity Period groundnut cultivation

: It matures between four to six months.

process of Harvesting groundnut

: Harvesting is done when the lower leaves turn brown and begins to fall. Harvesting is done by using native hoes or by pulling the plants up by hand. The nuts are then picked from the plant root and stem. Harvest 102 – 150 days after planting, depending on the variety. Harvesting can be done manually or mechanically by uprooting the plant and allowing them to dry for easy removal of pods.

Processing and storage of groundnut after cultivation

: Harvested nuts are dried properly. The seeds are removed from the shells by pounding them slightly in mortars or by beating them with sticks. Small shelling or decorticating machine can also be used to remove the seeds from the pod.
Storage: Dried groundnuts can be stored in clean rhumbus or silos. The unshelled pods are stored in sacks while the shelled nuts are stored in bags. The shelled nuts are treated with insecticides before storage.

Pests of Groundnut and control methods during cultivation

(1) Rodents: These include rats which dig up and eat sown seeds.
Control: Fencing and trapping should be done.
(2) Groundnut Beetle: This sacks the nuts during storage.
Control: Fumigation with phostoxin tablets should be done. Other pests include aphids. caterpillar and grasshopper, bruchid or weevil or floor beetle.

Diseases of groundnut and control methods

(1) Groundnut rosette disease: It is caused by a virus which is transmitted by aphid and other piercing and sucking insects.
Symptoms: Symptoms include green leaves which become yellow with mosaic form of mottling. The plant becomes stunted and finally withers and dies.
Control: (i) Plant healthy seeds. (ii) Uproot and burn infected plants. (iii) Spray to kill the vector (aphids) with insecticide.

(2) Tikka Disease: It is caused by a fungus (Cercospora personata), which can be spread by air or wind as in air-borne diseases and insect-borne disease

Symptoms: Symptoms include yellowing of leaves with dark brown spots on the under surface. Falling of the leaves soon will set in.
Control:
(i) Early planting. (ii) Practise crop rotation. (iii) Use resistant varieties. (iv) Maintain farm sanitation.
(3) Aspergillosis: It is caused by a fungus (Aspertilles Havus) which makes the seed become mouldy. Spores are transmitted through the soil. Pods become toxic because of the presence of aflatoxins which are poisonous. The hypocotyl of the geminating seeds will die.
Control: (i) Plant mould- free seeds.
(ii) Treat seeds with fungicides.
