Groundnut can be cultivated as a floor crop in coconut gardens, as an intercrop
with tapioca and as a catch crop after second crop paddy with irrigation. The crop
is grown best in sandy loam and loam soils.
Rainfed: May-June to Sept- Oct.
Irrigated: Jan- May
Note: TG-3, TMV-2 and TMV-7 are recommended as intercrops in coconut gardens.
Seed and sowing
Pure crop : 100kg kernels/ha
Intercrop in coconut : 80 kg kernels/ha
Intercrop in tapioca : 40-50 kg kernels/ha.
Plough the field 3-4 times into a fine tilth. Sow the seeds by dibbling in ploughed
furrows at a spacing of 15 x 15cm. For seed treatment, the rhizobial culture is
Cattle manure or compost: 2t/ha
Lime: 1-1.5 t/ha
Fertilizers N:P2O5: K2O – 10:75:75 kg/ha
Apply entire quantity of cattle manure or compost and recommended quantity of fertilizers
as basal dressing and incorporate well into the soil. Apply lime at the time of
flowering of the crop and mix with the soil by light hoeing or raking.
Irrigation and interculture
Irrigate the crop once in 7 days. Weed the crop 10-15 days after germination of
seed by light hoeing. Give another light hoeing or raking at the time of application
of the lime. Do not disturb the soil after 45 days of sowing.
Red hairy caterpillar, termites and leaf miner are the major pests of groundnut.Against
leaf miner apply any of the organo-phosphorous insecticides with contact action.
Spraying carbaryl 0.15% controls red hairy caterpillars. Against ants/ earwigs/
termites damaging the pods, apply carbaryl 10% DP in the soil at the time of seeding.
Tikka leaf spot disease infects both the rainfed and irrigated crops. Prophylactic
spraying with Bordeaux mixture 1% before flowering will control the disease.
The crop will be ready for harvest when the leaves start yellowing and begin to
dry up. Development of brown colour inside the pods also indicates maturity of the
