बैंगन की स्वस्थ पौद उगाना : एक पारिस्थितिकी अनुकूल दृष्टिकोण

Brinjal is the most common growing vegetables by small and marginal farmers In India, it is one of the most common, popular and principal vegetable crops grown throughout the country except higher altitudes. It is a versatile crop adapted to different agro-climatic regions and can be grown throughout the year.

It is a perennial but grown commercially as an annual crop. A number of cultivars are grown in India, consumer preference being dependent upon fruit colour, size and shape.It is a transplanted crop and raising of healthy seedling is very difficult by the farmers as the seedlings suffers from diseases and pest in nursery itself.

In nursery, during kharif season seedlings die due to attack of damping off disease and also possibility of viruses are there. Brinjal fruit and shoot borers feed inside the stem of the young seedlings which resulted in drying and death of terminal shoots.

Therefore precaution must be taken for raising healthy seedling which can give better field establishment of crops and higher yield and toxin free healthy fruits. These can be done by managing the nursery by ecofriendly approach without using harmful chemicals for environmental sustainability.

Seedling raising technique:

Raised bed for brinjal Nursery Seed sowing for raising brinjal seedlings

Nursery Bed Preparation:

Brinjal seeds are sown on raised nursery bed which is required to avoid problem of water logging in heavy soils. Before bed preparation, nursery area should be ploughed properly and kept for sun drying or solarization.

Fungal culture of Trichoderma virideis mixed with cow dung manure (@ 1 kg per 5 kg) at least 15 days before sowing and then these are mixed with nursery soil. Neem cake can also be given in the nursery.

Raised beds of size 3 m× 1 m and 10-15 cm in height are prepared. Thus, fifteen beds are sufficient to raise seedlings for planting one hectare area. An about 50 cm distance is kept between two beds to carry out operations of watering, weeding, etc. The surface of beds should be smooth and well leveled.

Seed rate for brinjal growing

Open pollinated Varieties: 400g/ha

Hybrids : 200-250 g / ha

Growing seedlings of Brinjal on raised bedBrinjal Seed treatment for raising seedlings

Seeds can be treated with Trichoderma viride culture (@4 g/ kg of seed) or Pseudomonas fluorescens(@ 10 g / kg of seed)to avoid damage from damping-off disease.

Raising of Seedlings:

Sowing is done thinly in lines spaced at 5-7 cm distance and at a depth of 2-3 cm. After sowing lines are covered with a fine layer of soil.

The beds should then be covered with dry grass to maintain required temperature and moisture and light watering is done by water can.

The watering should be done in morning and evening or as per the need till germination is completed. The cover of dry straw or grass is removed immediately after germination is completed.

Nursery bed should be covered with 50 % green shade net to protect the seedling from scorching heat and heavy downpour.

After germination regular watering should be done to keep the seedling healthy. Pheromone trap should be installed to keep the seedling free from fruit and shoot borer.

One pheromone trap per 5 nursery bed is sufficient. Yellow sticky trap is kept to catch various sucking pest which spread viruses.

After germination care

Water stagnation should be avoided. Hoeing should be done to loosen soil and easy aeration 10 days after germination. Regular hand weeding should be done to keep weed free.

Plant protection in Brinal

1. Fruit and shoot borer

  1. Remove the affected seedlings
  2. Spray Neem Seed Kernel Extract 5 % at 10 days after germination

2. Whitefly
Trapping of whitefly using yellow sticky trap at 1 trap per 5 bed.  Spray Neem oil 3% + Teepol (1 ml/lit) or spray Neem Seed Kernel Extract 5 %.

Seedlings for transplanting

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.
