Title: Organic farming is a system which do not use synthetic inputs such as chemical fertilizers, pesticides, hormones and relies on crop rotations, crop residues, animal manures, off-farm organic waste and biological system of nutrient mobilization and plant


1
Introduction
  • Organic farming is a system which do not use
    synthetic inputs such as chemical fertilizers,
    pesticides, hormones and relies on crop
    rotations, crop residues, animal manures,
    off-farm organic waste and biological system of
    nutrient mobilization and plant protection.
  • Organic farming promotes agro-ecosystem health
    and soil biodiversity and provides opportunity
    for export of horticultural crops.
  • People are becoming health conscious and ready to
    purchase organically grown food and plant
    products.

2
Impact of Green Revolution
  • Green Revolution in India has created lot of
    ecological and environmental problems like
  • Soil deterioration due to intensive cultivation
    and reduction in crop production from High
    Yielding Varieties.
  • Decrease in input use efficiency and declining
    water table.
  • Increase soil salinity and crop susceptibility to
    pest and diseases and pest becoming highly
    tolerant to pesticides.

3
Objectives of Organic Farming
  • To produce chemical free healthy food and
    conserve genetic diversity of crop plants.
  • To maintain and enhance long term soil fertility
    and encourage biological cycles involving soil
    flora and fauna.
  • To help in soil and water conservation and
    minimize various forms of pollution in
    agricultural practices.
  • To recycle agricultural waste products and
    preserve traditional and indigenous knowledge in
    farming system.

Approaches in Organic Farming
  • Use of Green Manuring crops
  • Composting and use of Organic Manure
  • Biological Pest Management
  • Crop Rotation for residual benefits
  • Bio-fertilizer application for soil micro-flora
    development
  • Integration of Animal husbandry in crop production

Approaches for Organic Farming
  • Use of Green Manuring Crops Green manure crop
    like dhaincha, sunhemp, cowpea etc incorporated
    in soil at proper stage can improve soil
    fertility and reduces cost of external inputs
    like fertilizers.
  • Composting and use of Organic Manure Organic
    manure like cattle dung, rural urban composts,
    animal wastes, crop residues can be recycled in
    to compost and used as manure for crop
    production. Organic manures like FYM. Compost,
    Oil Cakes, Bone meals, Blood meal can be used.

Approaches for Organic Farming
  • Biological Pest Management Biological agents
    like Trichoderma viride and Azadirachtin are
    effectively used to control pest and diseases in
    crops and pests are kept below economical
    threshold level.
  • Crop Rotation for Residual Effects It is
    practice of growing one crop after another on the
    same piece of land in different timings to
    enhance soil fertility through selection of crops
    which will help each other like Cereal crop
    rotated with Pulse crop in sequence.

7
Approaches for Organic Farming
Integration of Animal Husbandry Byproducts of
animal husbandry like dung and urine are used as
resources in organic farming. Bio-fertilizer
Application Bio-fertilizers like Azotobacter,
Azospirillum, Rhizobium, mycorrhiza are
preparations containing living cells of
micro-organisms that help crop plants in uptake
of nutrients by their biological interactions. It
is cost effective components of organic farming,
based on renewable source of plant nutrients.
