Friday Sharing Program of AgriYouthNepal Date: 3rd March 2015 Presenter: Dhiraj Bhatta Agriculture and Forestry University (AFU)

1. Sustainable Agriculture
For
Sustainable Future

3. How far have we come?
GREEN REVOLUTION:
• Crop improvement
• Mechanization
• Inorganic source of nutrients
• Chemical methods of plant protection

4. WHAT WE LOST……?
HEALTH

5. SOIL
Soil compaction
Soil erosion
Degradation of soil fertility

6. ECOSYSTEM
Bio magnification

7. ATMOSPHERE
Green house effects
Global warming
Climate change

8. WATER BODIES
Eutrophication

9. ARE THEY SAFE…?

10. ENERGY
How long will they support us?

11. THEN WHAT….? IS THERE
ANY ALTERNATIVE…?
SUSTAINABLE AGRICULTURE
(Gordon McClymont)
The act of farming using principles of ecology
An integrated system of plant and animal
production practices having a site specific
application and that will last over the long
time.

12. AIMS….
Environmental quality
Eco friendly
Rational use of resources
Economic viability
FINALLY
To satisfy present human needs
without compromising the base for
the future

13. WHAT ARE ITS DIFFERENT
APPROACHES?
Organic farming
Integrated farming
Permaculture
Ecofarming

14. HOW IT CAN BE REALIZED…?
SOIL/LAND
Conservation tillage(no till farming, minimum
till)
Crop- rotation(long term)
Biochar application

15. PLANT NUTRITION
• Organic source(FYM, compost, vermi compost…)
• Green manures
• Bio fertilizers
• N-fixing gene

17. PLANT PROTECTION MEASURES
• Bio insecticide
1. Virus: Nuclear Polyhedrosis virus(NPV): hairy
caterpillar
Orychtes Baculo virus(OPV):rhinoceros
beetle
2. Bacteria: B. thuringiensis
3. Fungi: Entomophora, Verticillium, Aspergillus

19. 4. Protozoa: Neodiprione
5. Nematodes: Neoaplectana glaseri - Japanese
beetle
6. Insects: Tiger beetle preys on rice earhead
bug, lady bird beetle feeds on aphids

20. • Bio pesticides
1.Agrobacterium radiobacter control crown gull
of apple caused by A. tumefaciens
2. Erwinia herbicola controls citrus canker
caused by Xanthomonas citri
3. Trichoderma spp to control foot rot of ground
nut, wilt of brinjal and aerial blight of
soyabean

21. • Soil solarization
• Disease and pest resistant varieties
• Biochar application
• Plants ( neem, onion, garlic etc)

22. WEED MANAGEMENT
• Bio herbicide
1. Cactus feeding moth (Cactobolustis
cactorum) to control prickly pear cactus
2. Cecidochorea utilis to control Eupatorium spp
3. Phytophthora

23. • Cultural practices
• Mulching
• Alleopathy

24. WATER MANAGEMENT
• Drip irrigation
• Sprinkler irrigation
• Rain water harvesting
• Mulching
• Drought tolerant varieties
• Drainage

25. FARM POWER/ENERGY
• Solar power
• Biogas
• Animal power

26. CHALLANGES
• Effectiveness
• Economic viability
• Productivity increment
Can it feed the increasing
number of mouths?

27. CAN WE REALIZE THE
DREAM TOWARDS
EVER GREEN
REVOLUTION?

30. Thank You
