Seed rate

On an average 370 – 500 g seed is required for raising required seedlings for one ha land.

Seed treatment 

Seed treatment with Trichoderma viridae / T. harzianum @ 2g /100 g of seeds to prevent seed and soil borne infection of fungal diseases. Or

Treat the seeds with (Carboxyn 37.5% + Thiram 37.5%) DS @ 1.5g or (Carbendazim 1.0g + Thiram 1.5g)/ kg of seeds.

Nursery

Raised beds are necessary to avoid problem of water logging in heavy soils

In sandy soils, however, sowing can be taken up in flat beds.

Raised beds of size 7.2 x 1.2 m and 10-15 cm in height are prepared.

Thus, ten such beds are sufficient to raise seedlings for planting one hectare area.

About 70 cm distance is kept between two beds to carry out operations of watering, weeding, etc.

The surface of beds should be smooth and well levelled. Well-decomposed FYM or leaf mould may be mixed with the soil at the time of bed preparation.

To avoid mortality of seedlings due to damping off, drenching of the beds with Bavistin (15-20 g/10 litres of water) is effective.

Sowing should be done thinly in lines spaced at 5-7 cm distance.

Seeds are sown at a depth of 2-3 cm and covered with a fine layer of soil followed by light watering by water can.

The beds should then be covered with dry straw or grass or sugarcane leaves to maintain required temperature and moisture.

The watering should be done by water can as per the need till germination is completed.

The cover of dry straw or grass is removed immediately after germination is complete.

During the last week in nursery, the seedlings may be hardened by slightly withholding water.

The seedlings are ready for transplanting within 4-6 weeks of planting when they attain a height of 15 cm with 2-3 true leaves.

Transplanting

Land Preparation

The field is ploughed to fine tilth by giving four to five ploughing with a sufficient interval between two ploughing.

Planking should be done for proper levelling. The field is then divided into beds and channels.

Well-decomposed FYM is thoroughly incorporated at the time of land preparation.

Spacing

Normally the long fruited varieties are transplanted at 60 x 45 cm, the round varieties at 75 x 60 cm and high yielding varieties at 90 x 90 cm spacing.

Seedlings are transplanted in furrows in light soils and on side of the ridges in case of heavy soils.

A pre-soaking irrigation is given 3-4 days prior to transplanting.

At the time of transplanting, the roots of the seedlings should be dipped in a solution of Bavistin (2g/litre of water).

Transplanting should preferably be done in the evening.

Manure and fertilizers

15-20 tonnes of well-decomposed FYM is incorporated into the soil.

Generally, application of 150 kg N, 100 kg P2O5 and 50 kg K2O is recommended for optimum yield

For hybrid varieties, the recommended dose is 200 kg N, 100 kg P2O5 and 100 Kg K2O.

Half dose of N 25 2 and full dose of P and K is given at the time of planting.

The balance half of N is given in 3 equal split doses.

The first split dose is given one and half month after transplanting, the second dose one month after the first application and the final at three and half months after transplanting.

Irrigation

A light irrigation is given on the first and third day after transplanting.

Thereafter irrigation is given at an interval of 8-10 days during winter and 5-6 days during summer.

Intercultural Operations

Two-three hoeing and the earthing up are required to keep the crop free of weeds.

Pre- emergence application of Fluchloralin (1.5 kg a.i./ha) coupled with one hand weeding 30 days after transplanting is effective for control of weeds.

Plant protection

Pests : Pests Fruit and shoot borer, jassids, Epilachna beetle and mites are the major pests.

Diseases : Diseases Bacterial wilt Fusarian wilt, Phomopsis blight, little leaf, mosaic and damping off are the major diseases.

IPM practices

Nursery

Always prepare raised nursery beds about 10 cm above ground level for good drainage to avoid damping off etc.

Cover the nursery beds with polythene sheet of 45 gauge (0.45 mm) thickness for three weeks during June for soil solarisation which will help in reducing the soil borne insects, diseases like bacterial wilt and nematodes. However, care should be taken that sufficient moisture is present in the soil for its solarisation.

Mix 250 gm of fungal antagonist Trichoderma viride in 3 kg of FYM and leave for about seven days for enrichment of culture. After 7 days mix in the soil in a bed of 3 sq. m.

Seed of popular hybrids like F1- 321 be sown in beds in the first week of July. Before sowing, seed be treated with T. viride @ 4 gm/ kg. Weeding should be done from time to time and infected seedlings should be rogued out from the nursery.

Main crop

Bird perches @ 10/ acre should be erected for facilitating field visits of predatory birds.

Delta and yellow sticky traps @ 2-3/ acre should be installed for hoppers, aphids and white fly etc.

Give 2 to 3 sprays of 5 % NSKE against sucking pests.

Sprays of NSKE also bring down the borer incidence significantly. Neem oil (2%) application is also helpful in reducing borer infestation, though marginally. If incidence of leaf hopper and other sucking insect pests is still above ETL, then apply imidacloprid 17.8 SL @ 150 ml/ha.

Pheromone traps @ 5/ acre should be installed for monitoring and mass trapping of shoot & fruit borer Leucinodes orbonalis. Replace the lures with fresh lures after every 15-20 day interval.

Relaese egg parasitoid T. brasiliensis @ 1 – 1.5 lakh/ ha for shoot & fruit borer, 4-5 times at weekly interval.

Apply neem cake @ 250 kg/ ha (in two splits) in soil along the plant rows at 25 and 60 DAT for reducing nematodes and borer damage. Don’t apply neem cake when there is heavy wind velocity or temperature is above 300C.

Clipping of borer damaged shoots and collection and destruction of damaged fruits i.e. clean cultivation helps in management of borer and phomosis disease effectively.

If the borer incidence crosses ETL (5% infestation), apply cypermethrin 25 EC @ 200 g a.i/ha (0.005%) or carbaryl 50 WP @ 3 g/litre of water or endosulfan 35 EC @ 0.07%.

Continuous cropping of brinjal leads to more borer and wilt infestation. Therefore, crop rotation with non-solanaceous crops should be followed.

Periodically collect and destroy the egg masses, larvae and adults of hadda beetle.

Rogue out the little leaf affected plants from time to time.

Use of green manure, mulching with polythene, soil application with bleaching powder will reduce the infection of bacterial wilt disease.

Harvesting and Yield

The fruits become ready for first picking in about 120-130 days of seed sowing depending on the variety.

Fruits are harvested when they become greenish yellow or bronze and their flesh turns dry and tough.

Pressing the thumb against the side of the fruit can indicate the maturity of the fruit.

If the pressed portion springs back to its original shape, the fruit is too immature

Some portion of the calyx and the stem-end is retained on the fruit during harvesting.

Since all the fruits do not mature at the same time, the fruits are harvested at an interval of 8-10 days.

Yield

Depending on variety and season the average yield of brinjal is 20-30 t/ha
