Introduction
Tomato is an important commercial vegetable crop
grown on large scale in India. It gives good
profit to the farmer. The tomato seeds are costly
and small, hence require nursery for due care in
production of seedlings. Raising the nursery of
tomato is a highly skilled job. The seedlings are
ideally grown on two types of beds.
2
Flat Bed
  • Traditionally used method of raising seedlings.
  • Width of the bed is adjusted so as to approach
    the centre of the bed conveniently.
  • This type of bed is prone to water logging and
    thus seedling decay.
  • It is not recommended specially during rainy
    season.

Raised Beds
  • Common type of bed adopted by professional
    vegetable growers.
  • The soil remains loose, water logging can be
    avoided and root growth can be intensified.
  • It also facilitates the air and light
    penetration, intercultural operations, pests and
    diseases managements.

4
Soil Preparation for Raised Beds
  • Deep ploughing and harrowing (30 cm deep) for
    fine tilth.
  • 10kg FYM, SSP 100g/m2 and Thimate 25g/bed applied
    before sowing.
  • The proportion of Soil and FYM is 31.
  • avoids water logging and maintains aeration.
  • The dimensions Width 1m, Height 0.30m, Length
    May vary as per the requirement and convenience.

Raising Seedling by Raised Bed Method
Bed Preparation
  • Prepare beds 9m long 1m wide and 15-20 cm high.
  • Tomato on 1ha area require seedbeds of 10x15m2
    size.
  • Break the clods and bring the bed to a fine
    tilth.
  • Apply 15 kg well decomposed FYM to each of this
    bed.
  • Mix 3g Trichoderma culture in 100g neemcake/m2 to
    soil.
  • Add 100g/bed of nitrogen, phosphorus and potash.

Sowing
  • F1 hybrids or improved varieties of tomato are
    preferred.
  • Seeds are sown in line at spacing of 7 cm and
    depth 1 cm.
  • Seed treatment of Thiram or recommended
    fungicide.
  • Fine sand is added in seed to enable proper
    spacing.
  • Seeds be covered with sieved soil and FYM layer.
  • Cover the bed with dry grass or straw until
    germination.

7
Care of Seedlings
  • Sprinkle 50-100g of insecticide dust formulations
    around nursery beds to prevent ants from eating
    seeds.
  • Drench with copper oxy chloride (3g/liter) after
    germination.
  • Cover beds with 40-50 mesh nylon net to protect
    from whiteflies, thrips and aphids.
  • Insect vectors are managed by spraying
    Imidacloprid _at_0.2ml/liter 7-10 days after
    germination and before transplanting.
  • The seedlings will be ready for transplanting in
    25-42 days.
  • Seedlings are hardened by holding irrigation and
    removing the nylon net before transplanting.

8
Use of Nylon Nets
Insect attack on plants in early stages can
affect growth and yield of the crop. Hence
vegetable seedling are grown under cover using
insect proof nylon net (40-50 mesh). The nets are
supported by Casuarinas or bamboo poles or GI
pipes. 150 square meter area is sufficient to
grow seedlings for 1 ha. This would incur an one
time expenditure of Rs. 5000.
Irrigation
Germination requires warmth and humidity.
Irrigation is applied frequently but precisely
with micro sprinklers to avoid displacement of
seeds. The first watering should be done in the
form of drenching with Bavistin 0.01.
9
Aftercare
  • Weeding Removal of weeds as required.
  • Pests Aphids, leaf miner, whitefly affect
    seedlings. They are controlled by spraying
    Malathion 0.02 (20mL/10L water) Neem seed
    kernel extract 4.
  • Damping Off It is a fungal disease caused by
    thick and compact sowing and poor drainage.
    Damping off causes mortality of seedlings. This
    can be prevented by seed treatment, drenching and
    spraying Bavistin 0.01(10g/10L water) at sowing
    and after germination.

Advantages of Raising Seedlings in Nursery
  • Healthy seedlings
  • Precision in seed use
  • Uniform growth of seedlings
  • Congenial conditions for growth
  • Proper management due to small area.
  • Timely availability of the seedlings
