Crop substitution – groundnut substituted with pigeonpea, castor, pearlmillet and sorghum

Crop rotation – kharif groundnut – greengram/ horsegram where Northeast monsoon is assured.

Drought tolerant varieties – Girnar-1

Deep tillage is done for reducing soil borne pest

Pearlmillet acts as a barrier for thrips and leaf miner

Castor acts as a barrier for spodoptera litura, Achoea janata

Groundnut + soybean for trapping leaf miner, thrips

Seed treatment: Carbendazim (Bavistin) 2 kg of seeds for seed borne fungi viz., collar rot and stem rot.

Seed treatment with Mancozeb (3 g)/ Carbendazim (2 g) for 1 kg of kernels

Cultural practices •

Soil amendment with castor cake @ 500 kg/ha (preferably 15 days before sowing) for soil borne diseases like stem rot and collar rot.

Intercropping of groundnut with pigeonpea/ pearlmillet/ sorghum (3:1) depending upon the locally recommended intercrops against foliar fungal diseases (early and late leaf spots, rust) and insect pests (leaf miner and thrips)

Use of trap crops such as cowpea/ soybean (leaf miner and leaf hoppers)/ castor (Spodoptera and leaf hoppers) as border crops for sucking/ defoliating insects.

One hand weeding at 30-35 days after sowing after the application of pre-emergence weedicide Fluchloralin @ 1.5 kg a.i./ha

Mahaboobnagar, Nalgonda, Warangal •

Varieties: JL-24

Seed rate: 100 kg/ ha

Seed treatment: Seed treatment with Mancozeb (4 g)/ Carbendazim (2 g) for one kg of kernals

Planting pattern: 30x10 cm

Nutrient management: 20 kg N + 40 kg P 2O 5+ 40 kg K 2O/ha.

10

In Zn deficient soils – apply ZnSO 4 25 kg/ha once in three years

50% recommended dose of fertilizer + Farm yard manure 5 t/ha in sequence crops

Pest management: •

Root grub: Apply Thimmet or Phorate granules at 10 kg/ha to soil before sowing or treat the seed with Chlorpyriphos @ 6 ml/kg seed.

Aphids, leaf miner: Spray 0.05% Endosulfan or Dimethoate or monocrotophos

Red hairy caterpillar: •

Arrange bonfires 2 days after soaking rain from 8.00 PM to 10.00 PM

Make a furrow around the field, and apply carbaryl dust in the furrow

For second and third instar larvae, spray Dimethoate @ 2 ml/l or Monocrotophos @ 1.6 ml/l

Poison bait with 10 kg rice bran + 1 kg jaggery + 500 ml Quinolphos can be applied for effective control.

Late leaf spot: Spray Mancozeb 2 g + Carbendazim 1 g/l or Hexaconazole @ 2 ml/l. Spraying can be taken up based on leaf wetness at 70 days after sowing. There is no need to spray for July sown crop.

Stem necrosis: Removal of weeds particularly Parthenium on the bunds and in the field
