Here some details in ppt about how to grow Tomatoes in Greenhouse.

2. TOMATOES
PLANTING
 Bed Preparation
• Top width - 90 cm.
• Path width – 50 cm
• Height – 40 cm.
 Planting Distance
 40-45 cm between two plants
 50 cm between two rows

3.  Planting Material
Seedling of four to five weeks age are used,
before flowering.
 Planting seasons:
June-July
November- December
 Types of Tomato
1. Beef stick tomatoes
2. Truss ( vine) tomatoes
3. Cherry tomatoes
4. Round tomatoes

5. CULTURAL PRACTICES IN TOMATOES
 Suckering
 Crop Support
 Training
 De-leafing
 Fruit Pruning
 Truss hooks
 Topping
Harvesting

6. Suckering
 Indeterminate growth habit
 suckers will develop between each compound
leaf and the stem. These suckers are removed
as they develop, leaving only the main stem as a
growing point.
 Side shoots are usually not pruned until they are
a few inches long, at which time they are easier
to distinguish from the main stem.

8. Crop Support
 Nylon strings hung from horizontal wires
at least 3 m about the ground
 A plant fully loaded with fruit weights 7 to
14 kg
 Each individual stem is clipped to a string
with special plastic clips (Tomato clip)
available in several sizes.

9. Crop Support

10. Training (Tying)
 Plants should be trained as single (main)
stem.
 The plants can be supported with the help
of plastic twine loosely anchored around
the base of the plants (non slip loop) at
one end.

11. De-leafing
– When vines are lowered, leaves touching the
ground are removed to prevent disease
development.
– To increase light penetration and air
circulation. Typically, all leaves are removed
below the lowest fruit cluster.

12. Fruit Pruning
 Small, undersized fruit at the end of a
cluster (distal fruit) are always removed.
 Truss hooks
grown under relatively low light
conditions, the peduncles of the
inflorescences (trusses) are too weak to
support the weight of fruit they bear
and, are liable to bend or ‘kink’.

13. Fruit Pruning

14. Truss hook

15. Topping
 Six weeks before the anticipated crop
termination date, the growing point and
small fruit clusters at the top of the plant
are removed.
 fruit requires 7-8 weeks from anthesis to
harvest so small fruit will not have
enough time to develop to maturity.
 Increase size of already-set fruit in the
lower part of the plant.

16. Pollination
 Hand pollination method is used, Timing is
important in hand pollination for fruit set. i.e.
when humidity conditions are most favorable
(50-70%). Pollination is done at least twice a
week; inadequate pollination will lead to
misshapen fruits and lower yields.

17. Pollination

18. Harvesting
 Production of tomatoes starts after 60-75
days the total crop period for tomatoes is
8-9 months after planting.
 Yield- i) Truss tomatoes - 50-60kg/ Sq.meter
ii) Cherry tomatoes - 31 kg/ Sq.meter
