Round the year (As per the Regional Practices and Timings)
|
| Field Preparation |
Prepare the land by ploughing once or twice, depending on the soil type. Mix 5 tons of Farm Yard Manure (FYM) . Spread this mixture evenly over the soil and use a rotavator to achieve a fine tilth throughout the field. Prepare raised beds, 90 cm wide bed preparation, by using a tractor.
|
| Seed Treatment / Rate / Timing / Chemical |
To protect seed from soil borne fungus, treat seed with Carbendazim@2 gram/kg of seed or Thiram@2.5 gram/kg of seed before sowing.
|
| Spacing |
60 cm between rows and 20-25 cm between plants.
|
| Seed Rate |
3 Kg/acre
|
| Fertilizer Dose with Timing |
- 120:60:40 NPK / Ha.
- Basal Dose per acre includes 50 kg of DAP, 50 kg of MOP, and 10 kg of Micronutrients.
- After 20 days, apply 50 kg of Urea, 10 kg of Magnesium Sulphate, and 10 kg of Zinc Sulphate as top dressing.
- After 40 days, apply 50 kg of DAP and 25 kg of Urea as top dressing.
- After 55 days, apply 50 kg of Urea based on specific crop requirements.
|
| Weed Control - Chemicals with Doses and Timing |
Timely weed removal is very important, need-based hand weeding can be done to ensure a healthy crop.
|
| Diseases & Pest Control |
- Pest
Fall Armyworm
The larvae initially feed on the lower parts of the leaves, leaving semi transparent patches. As they mature, they can defoliate plants extensively. Their feeding on young plants may also destroy the growing point, preventing the development of new leaves or cobs.
- Mechanical Control: Install Pheromone trap @ 5 per acre.
- Organic control: Spray Neem oil @ 2 ml per lit water.
- Chemical control: Spray Emamectin benzoate 5% SG – 0.5 gm OR Chlorantraniliprole 18.5% SC – 0.4 ml OR Profex Super Insecticide – 2 ml per Liter water.
- Aphids
Aphids harm plants by extracting sap from leaves. Their extensive feeding causes leaves to yellow and develop brownish-red streaks.
- Mechanical Control: Install Yellow and Blue sticky traps @ 10 per acre.
- Organic Control: Spray Neem oil @ 2 ml per lit water.
- Chemical Control: Spray Acetamiprid 20% SP – 0.5 gm OR Thiamethoxam 25% WG – 0.5 gm OR Ulla Insecticide 0.4 gm OR Imidacloprid 17.8% SL – 0.5 ml per Liter.
- Stem borer and Corn Borer
Stem borer larvae tunnel through the midrib and stem, consuming internal tissues, while corn borers feed on tassels, foliar tissues, and midribs. As older larvae tunnel deeper into stalks, ears, and kernels, they cause extensive damage to the plant.
- Chemical Control: Spray Emamectin benzoate 5% SG – 0.5 gm OR Chlorantraniliprole 18.5% SC – 0.4 ml OR Ampligo insecticide 0.5 ml per Liter water.
- Disease Management
The following diseases are harmful to Sweet corn farming and directly affect the yield of the Sweet corn crop.
- Downy Mildew
Affected plants show chlorotic streaks on the leaves, accompanied by white powdery growth on both leaf surfaces. This condition stunts plant growth, causing a bushy appearance due to shortened internodes.
- Organic Control: Spray Pseudomonas Fluorescens 1 gm per Liter water.
- Chemical Control: Spray Advancer Glow @ 3 gm OR Curzet @ 2.5 gm/Liter water.
- Leaf Blight:
Mature symptoms manifest as distinctive cigar-shaped lesions, measuring 3 to 15 cm in length. These elliptical lesions exhibit a tan coloration with distinct dark areas. Initially appearing on lower leaves, they progressively spread to upper leaves and ear sheaths as the crop matures.
- Organic Control: Spray biofungicide Trichoderma viride 200 gm per acre.
- Chemical Control: Metalaxyl 8% + Mancozeb 64% WP – 3 gm OR Dow Curate 3 gm OR Taqat – 2 gm per Liter water.
