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
