Method of seed production

    Method of seed production
    • Seed to seed
    Stages of seed production
    • Breeder seedīƒ Foundation seedīƒ  Certified seed.
    Varieties
    • Samba Varieties: K1, CO1, Pusa Jwala, PKM1, CO3, K2, Pant C1, G4
    • Gundu Varieties: CO2, G5 (Andhra Jyoti), PMK1, PLR1, CO4
    • Notified Varieties: G5, Chanchal, CO1, CO2, Hot Portugal, Jawhar mirch 218, Jwala, K1, K2, MDU1, Pant C1, Panjab lal , PKM1, Sanauri, Sindhur
    Hybrids
    • KT.1, (Pusa Deepti), Solar Hybrid 1, Solar Hybrid 2. Early Bounty, Indira, Lario, Hira, Bharat.
    Season
    • June July, February March, September October.
    Land requirement
    • There is no land requirement as of previous crops, but the land should be free from volunteer plants.
    • Generally areas affected by wilt or root rot may be avoided. Crop rotation must be followed to avoid endemic solanaceous pests.
    Isolation requirement
    • Minimum isolation distance of 400 M for foundation and hybrid seed and 200 M for certified seed production are necessary.
    Seed rate
    • Seed required for one hectare is 500 g to 1 kg for variety; for hybrids Female - 200 g and male - 50 g
    Seed Treatment
    • Seeds should be treated with captan @ 2g/kg or Trichoderma viride @ 4g /kg of seed and also seed treatment with Azospirillium @ 0.1 % improved the seedling vigour in chilli.
    Nursery
    • Sowing the seeds in raised nursery bed of 20 cm height, in rows of 5 cm gap and covered with sand.
    • Eight and ten nursery beds will be sufficient to transplant one acre.
    • Application of 2 kg of DAP 10 days before pulling out of seedlings.
    Transplanting
    • The seedlings of 30 35 days old are ready for transplanting.
    • Transplanting may be done on the ridges in the evening.
    Foliar spray
    • To arrest the flower drop, NAA (Planofix) can be sprayed @ 4ml/litre of water.
    • Very light irrigation is also done to arrest the flower drop.
    Manuring
    • Application of 50 tonnes of FYM/ha for irrigated crop.
    • Basal 100:70:70 kg of NPK and 50 kg of N at 15 days after transplanting and 50 kg N at 45th days after transplanting.
    Roguing
    • Field inspection and roughing should be done both for varieties and hybrid at different stages based on the plant height and its stature, flower colour and pod characters.
    • The plants affected with leaf blight, anthracnose and viral diseases should be removed from the seed field.
    Specific Field Standards
    Factors Foundation Certified
    Off types (max) 0.1% 0.2%
    Designated diseased plant (max) 0.1% 0.5%

    • The designated diseases are caused by Collertotictum capsici and leaf blight caused by Alternaria solani.
    Pest and disease management
    Pests
    Fruit borer
    • Spraying of carbaryl 50 WP 3 g/lit or chlorpyriphos 20 EC 3 ml/lit or quinalphos 25 EC 2 ml/lit.
    Thrips
    • Spraying of dimethoate 30 EC 2 ml/lit or methyl demeton 25 EC 2 ml/lit or formothion 2 ml/lit or dust quinalphos 1.5 D at 20 kg/ha thrice at fortnightly intervals.
    Aphids
    • Acephate 75 SP 1 g/lit or methyl demeton 25 EC 2 ml/lit or phosalone 35 EC 2 ml/lit.
    Yellow Muranai mite
    • Spray dicofol 18.5 EC 2.5 ml/lit or ethion 50 EC 4 ml/lit or wettable sulphur 50 WP 6 g/lit.
    Rootknot nematode
    • Application of TNAU formulation of VAM (containing 1 spore/g to control root knot nematode in nursery).
    Diseases
    Damping off
    • Treating the seeds with Trichoderma viride 4 g/kg or Pseudomonas fluorescens 10g /kg of seed 24 hours before sowing.
    • Apply Pseudomonas fluorescens as soil application @ 2.5 kg/ha mixed with 50 kg of FYM.
    • Stagnation of water should be avoided.
    • Drenching with Copper oxychloride at 2.5 g/lit at 4 lit/sq.m
    Leaf spot
    • Spraying of Mancozeb 2 g/lit or copper oxychloride 2.5 g/lit.
    Powdery mildew
    • Spraying of Wettable sulphur 3 g/lit or Carbendazim 1 g/lit, 3 sprays at 15 days interval from the first appearance of symptom.
    Die-back and fruit rot
    • Spraying of Mancozeb 2 g/lit or copper oxychloride 2.5 g/lit thrice at 15 days interval starting from noticing the die-back symptoms.
    Chilli mosaic
    • Raising two rows of maize or sorghum for every five rows of chilli crop against wind direction.
