Sustainable Agriculture For
Sustainable Future
How far have we come?
GREEN REVOLUTION:• Crop improvement
• Mechanization
• Inorganic source of nutrients
• Chemical methods of plant protection
WHAT WE LOST……?HEALTH
SOIL
Soil compaction
Soil erosion
Degradation of soil fertility
ECOSYSTEM
Bio magnification
ATMOSPHERE
Green house effects
Global warming
Climate change
WATER BODIES
Eutrophication
ARE THEY SAFE…?
ENERGYHow long will they support us?
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.
AIMS….Environmental quality
Eco friendly
Rational use of resources
Economic viability
FINALLY
To satisfy present human needs without compromising the base for the future
WHAT ARE ITS DIFFERENT APPROACHES?
Organic farming
Integrated farming
Permaculture
Ecofarming
HOW IT CAN BE REALIZED…?
SOIL/LANDConservation tillage(no till farming, minimum
till)
Crop- rotation(long term)
Biochar application
PLANT NUTRITION• Organic source(FYM, compost, vermi compost…)
• Green manures
• Bio fertilizers
• N-fixing gene
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
4. Protozoa: Neodiprione
5. Nematodes: Neoaplectana glaseri - Japanese beetle
6. Insects: Tiger beetle preys on rice earheadbug, lady bird beetle feeds on aphids
• 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
• Soil solarization
• Disease and pest resistant varieties
• Biochar application
• Plants ( neem, onion, garlic etc)
WEED MANAGEMENT
• Bio herbicide
1. Cactus feeding moth (Cactobolustis cactorum) to control prickly pear cactus
2. Cecidochorea utilis to control Eupatorium spp
3. Phytophthora
• Cultural practices
• Mulching
• Alleopathy
WATER MANAGEMENT
• Drip irrigation
• Sprinkler irrigation
• Rain water harvesting
• Mulching
• Drought tolerant varieties
• Drainage
FARM POWER/ENERGY
• Solar power
• Biogas
• Animal power
CHALLANGES
• Effectiveness
• Economic viability
• Productivity increment
Can it feed the increasing
number of mouths?
CAN WE REALIZE THE DREAM TOWARDS
EVER GREEN REVOLUTION?
Thank You
