India is the second largest producer of vegetable crops in the
world. However, its vegetable production is much less than the
requirement, if balanced diet is provided to every individual.

Why protected cultivation?Why protected cultivation?
In the changing scenario of increasing
population, decreasing cultivable land / water
resources, increasing urbanization/industrialization there
is need to produce more from available resources.
Further, with globalization of markets and global
climate change, greenhouse cultivation of high value
crops has emerged as the only top most important
technology for ensuring high productivity, improved
quality, lucrative return and continue supply.

What is Protected cultivation?
Protected cultivation can be defined as a cropping
technique where in the micro environment surrounding
the plant body is controlled partially / fully as per plant
need during their period of growth to maximize the
yield and resource saving.
They are different type of protected structure :
Poly house
Glass house
Net house
Plastic low tunnel

quality harvest.
Remove excess growth
Force plants to give desired/ certain shape.
Minimize direct contact with the soil.
Maximum use of resources.

PruningPruning
Tomato crop require pruning of all lateral branches.
Pruning must be done on a frequent schedule (every 3 to 4
days) .
Care should be taken to remove only suckers and not the
main terminal bud.
Pruning is done early in the day when plants are turgid.
The pruning time should be used to inspect plants for
obvious problems such as disease, nutritional
deficiencies, insects etc.
All pruned plant material should be placed in a container and
removed from the greenhouse.

The main stem is allowed to grow along the supporting
string and the growing point is removed at the 6th leaf
stage.
• The two emerging lateral branches are trained into V
shape on the overhead wire.

Single stem training in tomato :
Single main stem should be retained in the tomato crop
by removing all side shoots or suckers .
Plants are supported by plastic or binder twine, loosely
anchored on the base of the plants with the help of
plastic clips .

In this system of training two main shoots are
maintained as a leaders after topping.
Side shoots are pinched after one or two pairs of leaves,
generally one fruit is kept per side shoot.

Mulching
Mulching is done to cover
the soil around plants with a
protective material, which
may be organic or synthetic.
It reduces evaporation of
water from the soil.
Prevents compaction of the
soil surface.
It prevents the leaching of
fertilizer.
It suppress the weed
growth.

POLLINATION
In the greenhouse, wind is not strong enough to
shake the flowers sufficiently to transfer the pollen.
The optimum temperature for pollination is within
the range 21 to 27° C.
Optimum relative humidity is 70 percent. Above 80
percent relative humidity, pollen grains are not
dispersed well.
Different methods are used for effective
pollination and good quality yield.
1. Hand pollination
2. Battery operated vibrator
3. Air blowers
4. Bumble bees

Battery operated vibrator :
Greenhouse tomato growers should use an electric pollinator
to ensure good fruit set.
Air blowers :
It take half the time to pollinate the same number of plants
compared to electric vibrator.
In general, 5 % reduction in yield if you use this device.

Bumble bees :
Bumble bees are excellent pollinators for greenhouse tomato.
Estimated that each bee can pollinate up to 350 flowers.

De-leafing
When leaves of vines touch
the ground are removed to
prevent diseases development.
The amount of de-leafing that
occurs higher up the plant
varies between growers.
The purpose of de-leafing
higher up the plant stem is to
increase light penetration and
air circulation.

The crop beds are drenched
using 4 per cent
formaldehyde (4 l/ m2 of
bed) and covered with
black polyethylene mulch
sheet.
Four days after formalin
treatment, the polyethylene
cover is removed.
Fumigation
Four days after formalin
treatment, the polyethylene
cover is removed.
The beds are raked
repeatedly every day to
remove the trapped formalin
fumes completely, prior to
transplanting.
26

Side shoots (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 attain a few
inches long, at the time, they
easier to distinguish from the
main stem.

The growing point and
small fruit clusters at the
top of the plant are
removed this operation is
called topping.
Topping is carried out for
rapid fruit development
and improving size of
already-set fruit in the
lower part of the plant.
To avoid sunburn the
shoots are left to grow at
the top.

Staking
Immediately after
transplanting plant stems
should be secured to
nylon/plastic (high density)
twine, and quality of twine
should be ensured.
Twines are hung from
horizontal wires at least 3 m
about the ground.
Horizontal wires must be
sturdy enough to support the
weight of all plants in the row.

29

Fruit thinningFruit thinning
Small, undersized fruit are always removed, as these
will generally not grow to marketable size and reduce
the size of the other fruit.
This technique is powerful, so use it with great caution.
The optimum number of fruits per plant varies with the
cultivar and even more or less, with the growing
conditions.
Farmer may decide to remove too many fruits and
ultimately unnecessarily limit the production.
Fruit must be pruned or removed as soon as it can be
handled, before it grows too large.

Conclusion
Various horticultural practices likes as pruning, training, staking,
mulching, PGRs and pollination found effective for achieving significant
higher yield.
In tomato, single stem training reported better vegetative and
reproductive characters of crop. While in case of capsicum four leader
system found higher yield with its attributes.
In capsicum, four shoot pruning system with NAA @ 10 ppm had
significantly improve the yield characters.
In case of PGRs, NAA @ 20 ppm significantly improve the marketable
yield.
In case of pollination, bumble bee found best for fruit set and higher
yield under poly house conditions.
Use of black polythene mulch and double shaded polythene mulch gave
higher yield with good quality fruits
Use of the red shed net in fenugreek, coriander and garlic significantly
improve vegetative and reproductive growth.
