Land and water are the two essential factors
required for agricultural development and economic advancement of a country
There is a need to maximize per unit
production by better & efficient use
of these two natural resources
Efficient nutrient and water management
practices improve nutrient and water use efficiency, crop
yield and reduce environment pollution
Tunnel farming structure for high value /off season
vegetables
The Agriculture sector
of Pakistan directly adds 2104% to its GD, Provide40% employment and 60%
experts.
The Production of Horticultural Crops including Fruit and
vegetables have been estimated at 15.12 Million tones
The vegetable contribute 50% Share in the national
Horticulture production of Pakistan from more than 600,000 hectares
The rank of vegetable in term of area and production include
Potato, Onion, Tomato, Turnip, Carrot, Cauliflower, Chilies, Radish, Lady finger and Squash.
The Production of high value crops including sweet pepper,
hot peppers, tomato, cucumber, gourds, zucchini, eggplant are way below the top
ten vegetable products of Pakistan.
This allows the growers a greater demand and market price
for these products. With a total
production of 8.1 Million tones, the high value/off season vegetables are produced to the tune of 350,000 tons only
or 4.5%.
This presents a great deal of demand from the market side
and the consumers who are ready to purchase these high value crops mostly used
as salads and vegetable curries in everyday life.
The production of these high value off-season vegetables in
Pakistan is a new technology. Way back in 2003, it was initiated in Pakistan
through a private sector venture in Mamon Kanjan, Faisalabad.
The concept was well developed and got popularity all over
the country. The same model has become key interest for growers of KPK, Gilgit
and other regions, who want to improve their farm productivity and income as
well.
The farmers who had switched from traditional crops like
wheat, sugar cane and cotton, to these new high value vegetables through forced
cultivation (tunnel technology) have obtained much higher profits.
Through this technology the interior temperature is raised
inside the covered structure to grow different vegetables. In this way,
off-season vegetables are made available in the market 30-45 days earlier of
their real season.
There is a huge demand for fresh vegetables in the local as
well as international markets, which includes Europe, Middle East, and Far
Eastern market
IMPORTANCE OF
VEGETABLES
•
Contain
essential human food nutrients, which are absent in other consumables.
•
Rich and
economical source of vitamins, carbohydrates, minerals and other salts
necessary for human life.
•
Act as
defensive shields against numerous harmful diseases.
IMPORTANCE OF
Tomatoes
Tomatoes, aside from
being tasty, are very healthy as they are a good source of vitamins A and C.
Vitamin A is
important for bone growth, cell division and differentiation, for helping in
the regulation of immune system and maintaining surface linings of eyes,
respiratory, urinary and intestinal tracts.
Vitamin C is
important in forming collagen, a protein that gives structures to bones, cartilage,
muscle and blood vessels. It also helps maintain capillaries, bones and teeth
and aids in the absorption of iron.
Lycopene is a very
powerful antioxidant which can help prevent the development of many forms of
cancer.
A raw tomato has
about 20% of the lycopene content. However, raw or cooked tomatoes are
considered the best source for this antioxidant.

Objective
To reduce the impact
of high and low temperature fluctuations and hail storms that often affect crop
yields, as well as to grow crops off season to guarantee food supply at the
household level to local farmers
Improving Farming
System
Growing of off-season
vegetable (tunnel farming), fruit plant nursery raising, train farmers in new
technologies can help to improve the
socio- economic condition of the farming
communities
Types of protected
structures
Ø Green houses
Ø Plastic houses
Ø Screen house
Ø Tunnels
BASIC FACTS
Vegetables are a
required source of vitamins, proteins, essential nutrients and carbohydrates
for a balanced diet.
In Pakistan, farmers
are limited to grow seasonal vegetables and are dependent on marketing
mechanism of demand and supply.
Growing off-season
vegetables and fruits means improving the diet and increasing the household
income.
In the absence of
storage infrastructure and vegetable processing industries, off-season
vegetable farming is the only viable option that can add value to the farmers’
produce.
Temperature
fluctuations during summer make the vegetable crop susceptible to insects,
pests and diseases and similarly, cold temperature during winter create
favorable conditions for diseases.
The tunnels offer
protection to vegetables crops both in summer and in winter. The tunnel farming
offers maximum crop yields, better maintenance of the fertility of land,
controlled temperature and humidity, protection from wild animals and insects
and better water conservation.
In order to produce
vegetables under protection, it is necessary to consider a wind-free area, but
if this is not possible, windbreaks should be erected or planted.
Water must not be
very saline, as it is further enriched by the addition of fertilizers. Finally,
the tunnel must preferably be situated close to a market, in order to
facilitate that products reach the market place as soon as possible.
Crops such as
cucumber, tomato, pepper, bitter gourds, melons, brinjal and water melon are
highly valued vegetables that show significant increase in yield when grown in
tunnel farming
