Seed Treatment
For effective seed treatment, use Thiamethoxam 30% FS at 10 ml / kg seed to protect against sucking pests. Combine with Carbendazim 50% WP at 3 gm / kg seed to prevent fungal diseases. This dual treatment ensures healthier germination and robust plant growth.
Nursery Preparation
There are two methods of nursery preparation mentioned below:
Method 1:
For transplanting in a 1-acre area, a nursery of 0.1 acre (4 Guntha) is needed. Prepare four beds measuring 7.2 m in length, 1.2 m in width, and 10 cm in height. Sow seeds in lines 5 cm apart and cover them with soil. Water the nursery beds twice daily until germination, then once daily afterward. Reduce water application ten days before transplanting to harden the brinjal seedlings. Three days post-germination, drench the seedbed with Ridomil (20 gms in 10 liters of water) to prevent damping-off disease. At 25 days after sowing, spray a solution of 19:19:19 (5 gm) and Thiamethoxam (0.25 gm) per liter of water.
Method 2:
Fill pro trays with cocopeat at a rate of 1.2 kg per tray. Sow treated seeds in the trays, one seed per cell. Cover the seeds with cocopeat and stack the trays, covering them with a polythene sheet until germination begins (5 days). After 6 days, place the trays with germinated seeds individually on raised beds inside a shade net.
Spacing
- Row Spacing: Maintain a distance of 90-120 cm between rows.
- Plant Spacing: 45-60 cm between plants within a row.
Nutrient Management
- NPK Fertilization: Apply 100 kg of nitrogen (N), 75 kg of phosphorus (P), and 50 kg of potassium (K) per acre.
- Basal Dose Application: Incorporate a basal dose of NPK at 50 kg of nitrogen, 75 kg of phosphorus, and 50 kg of potassium per hectare during initial soil preparation.
- Top Dressing: Administer an additional 50 kg of nitrogen per acre as a top dressing 30 days after planting, or during the earthing up process.
Irrigation Management
- Frequency: Regular irrigation is crucial, especially during flowering and fruiting stages.
- Methods: Drip irrigation is highly recommended for efficient water use and uniform distribution.
- Water Management: Avoid waterlogging; ensure proper drainage.
Intercultural Operations
- Weeding: Regular weeding is essential to reduce competition for nutrients and moisture.
- Thinning: Thin seedlings to maintain the recommended plant population.
- Mulching: Apply organic mulch to conserve moisture and control weeds.
Crop Protection
Crop protection includes pest and disease management. Below are the pests and diseases that affect Brinjal crops.
Pest Management
Leaf miner
Leaf miners are larvae that feed on the mesophyll tissue within leaves, creating irregular mines that may become necrotic. They can also tunnel into stems, hindering plant development, and sometimes attack the fruit as well.
Organic Control: Spray Neem oil @ 2 ml per lit water
Chemical Control: Spray Abamectin 1.9% EC – 0.5 ml OR Thiamethoxam 25% WG – 0.5 gm OR Cartap Hydrochloride 50% SP – 1.5 gm per liter water.
Sucking Pest – Thrips, Aphid, Whitefly, Jassids
In Brinjal crop, sucking pests like thrips, aphids, and whiteflies suck the leaf sap, weakening the plants and leading to stunted growth and reduced yields.
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 Dimethoate 30% EC 2 ml OR Imidacloprid 17.8% SL – 0.5 ml per liter
Fruit and Shoot Borer
The larva penetrates young shoots, leading to the wilting of terminal shoots or dead hearts. It also tunnels into leaf petioles, flower buds, and developing buds, resulting in leaf wilting, bud drop, and rendering fruits unsuitable for consumption.
Mechanical Control: Install 4-5 Fruit borer traps per acre in the field.
Chemical Control: Spray Emamectin benzoate 5% SG – 0.5 gm OR Chlorantraniliprole 18.5% SC – 0.4 ml OR Ampligo insecticide 0.5 ml OR Gracia Insecticide 1 ml per liter water.
Nematode
Symptoms include premature leaf fall, wilting and decline in growth and fruit production. Roots of infected plants show typical galls / knots.
Organic Control: Drench Paecilomyces Lilacinus @ 2 lit per acre.
Chemical Control: Drench Bayer Velum Prime – 300 ml per acre.
Red Mite
Nymphs and adult insects feed on plant sap, causing white patches to appear on the leaves. Affected foliage becomes mottled, eventually turning brown and dropping from the plant.
Chemical Control: Spray Diafenthiuron 50 % WP – 1 gm OR Propargite 57 % EC – 2.5 ml OR Spiromesifen 22.9 % SC 1 ml per liter water.
Disease Management
The following disease are harmful to Brinjal farming and directly affect the yield of the Brinjal crop.
Alternaria Leaf Blight
Small, yellow-brown spots with a yellow or green halo initially appear on the oldest leaves.
Chemical Control: Spraying of Ridomil Gold @ 2 gram OR Antracol (Propineb)@ 2.5 gram per liter water.
Cercospora Leaf Spot
The disease initially manifests as small spots with light to tan brown centers on older leaves. As it progresses, these lesions enlarge, covering significant portions of the leaf surface.
Chemical Control: Spray saaf fungicide @ 2 gm OR Curzet @ 2.5 gm/liter water.
Bacterial Wilt
Symptoms of bacterial wilt include wilting, stunting, yellowing of foliage, and ultimately the collapse of the entire plant, marking the disease’s distinctive characteristics.
Organic Control: Drench biofungicide Pseudomonas Fluorescens 500 gm per acre.
