Techniques in High Tech Agriculture

2. GROUP MEMBERS :

3.  Introduction of High-tech Agriculture
 Characteristics
 Importance of Post Harvest
 Advantages and Disadvantages
 Scope for Post Harvest

4.  High tech agriculture is a knowledge based agriculture
system that makes use of technology to increase the
value and quality of the farms produce.
 Found around densely populated urban areas where
land is limited and costly.
 It uses computer technology and automation to manage
processes such as watering, fertilizing and pest control
to ensure high-quantity and high-quality crops.

5. 1. Purpose :
 Outputs produced in high-tech agriculture are mainly
for commercial purposes.
 They are either sold locally or exported overseas.
2. Inputs :
 High capital inputs are requires.
 Set-up cost of high-tech farms can be as much as a few
millions dollars.

6.  Technology : Hydroponics, Aeroponics and Tissue
culture.
 Shelters and Greenhouse : to create condition close to
ideal for plant growth.
 Computers and Automation devices : To automatically
adjust the temperatures and amount of moisture in the
special buildings to suit the growth of crops or animals.
 Research and Development : continual improvement of
existing technologies, to know the needs of the market
and to meet market demands.

7. 3. Outputs :
 Variety of high quality outputs are produced.
 Examples- Vegetables, flowers, fruits, ornamental fish,
eggs and other dairy products.
 Impacts on the Environment-
 More environmentally friendly than soil based farming.
 Water is supplied directly to the plant roots, thus
wastage of water is minimized.
 Minimizes wastage of resources.
 Uses less water and land.

8.  Methodology of soil-less cultivation.
 It is a method of growing plants using mineral nutrient
solution in water, without soil.
 Advantages:
 No soil is needed for hydroponics.
 Water stays in the system & can be reused.
 Stable and provides high yields, hence economically
valuable.
 Control nutrition levels accurately.
 Pests and diseases are easier to get rid.
 Ease of harvesting.

10.  Methodology of growing plants in air and mist environment
without use of soil.
 Uses water and fish waste and conducted without a growing
medium.
 Advantages:
 It ensures a steady supply of water, which allows farmers to
grow greater amounts and wider varieties of crops.
 Land previously unsuitable are made through irrigation.
 It reduces the need of human labours by using computers.

12.  It is a technique of growing cells, tissues, organs or whole
organism in vitro (in glass) on artificial culture medium
under aseptic and controlled conditions.
 Used to produce clones of plant in a method known as
micropropagation.
 Advantages :
 Reduce time to propagate plant.
 Save time for crop improvement selection.
 Can create potential disease free plants.
 Can conserves endangered species.
 Save space and reduce cost for land use.

14.  A greenhouses is a structure with walls and roof made
chiefly of transparent material, such as glass in which plants
requiring regulated climatic conditions are grown.
 Advantages :
 Yield may be higher than 12-13 times higher than out door
cultivation.
 Ideally suited for vegetables and flower crops.
 Disease free and genetically superior transplants can be
produced continuously.
 Maintenance of stock plants, cultivating grafted plant-lets
and micro propagated plant-lets.

16.  Extend support to GM plants or plant biotechnology.
 Best way to utilizing the potential of floriculture.
 Efficient utilization of chemicals and fertilizers.
 Water requirements of crops very limited and easy to
control.
 The yield may be 10-12 times higher.
 Export oriented view.
 Major beneficiary to small holding farmer.

17.  Crops are grown closely together hence more plants can
be grown per unit land.
 Plants are grown in soil or nutrient solution, they are
not exposed to soil disease or bacteria.
 Crops in soil less cultivation has the direct intake of
nutrient so it is more healthier.

18.  High Capital :
 Large amount of money is needed to place machines
and computer.
 Huge amount of electricity is required.
 High Labour :
 Labour are required for injecting nutrients to the
machines for plants.
 Need for more Research and Development :
 Many steps and prevention must be taken before
carrying out high tech agriculture. Hence lots research
is needed.

19.  There is tremendous production of fruits and vegetables in shorter
period. Therefore to avoid the post harvest loss.
 Increase substantial returns to processors for off season
consumption.
 Availability of cheap labour, government subsidy for cold storage
and processing units, convenience of roads in case for marketing
and transport.
 Availability of cans, bottles and other equipments at cheap rate,
there is tremendous for export of processed products like jam, jelly,
marmalade, pickles, etc.
 Dehydrated and dried vegetables in addition to domestic demand
in India.
