conservation agricultural improved practices in cropping systems
Conservation agriculture aims to conserve, improve
and make more efficient use of natural resources
through integrated management of available soil , water
and biological resources combined with external inputs.
It contributes to environmental conservation as well as
enhanced and sustained agricultural production. It can
be defined as resource efficient or resource effective
agriculture. ( FAO,2008)
Population pressure & Unsustainable use of land
Severe land degradation and food insecurity
so, we have to produce more food from less land
through more efficient use of natural resources and
minimum impact on environment.

 Globally , CA is practiced in 106 Million ha.
USA : 27 m ha
Brazil : 26 m ha
Argentina : 20 m ha
Canada : 13 m ha
Australia : 12 m ha
Asia : 3.3 m ha
Paraguay : 2.4 m ha
Europe : 0.5 m ha
Africa : 0.5 m ha
( Derpsch , 2009)
CA is based on three principles
 Minimum mechanical soil disturbance.
 Permanent organic matter soil cover especially by
crop residues and cover crops.
 Diversified crop rotations in annual crops or plant
associations in perennial crops including legumes.

 Water Harvesting and Recycling
 Water Saving Irrigation Methods
 Laser Leveling
 In-situ Moisture Conservation Measures
 Other Water Saving Measures
 Alternate Land Use System
 Basic principle of rain water harvesting -‘catch water
where it falls’
 Different water harvesting systems are
 Surface Water Harvesting
 In situ rainwater harvesting
 Roof top rainwater harvesting
 Sub surface flow harvesting
 To improve irrigation efficiency of irrigation systems
 Water saving irrigation methods
 Micro irrigation
 Furrow irrigation in raised bed planting system
 Surge flow furrow irrigation

conservation agricultural improved practices in cropping systems
Sustainable agriculture is a system to manage the
natural resources in such a way that production functions
of future generation do not suffer (FAO)
Improvement of biological basis for long term
agricultural production by emphasizing on management
of renewable resources ( Hoffman & Caroll)

 About 100-170 mm of water was saved by method of
furrow irrigation in cotton compared to flooding
(Singh et al. 1995).
 Sprinkler irrigation improved the crop yield by 5% to
35% and saved water from 23% to 56% over
conventional irrigation methods in different crops
(Kumar and Sharma, 1999).
Resource Conserving Technology Potential benefits relative to
conventional practices
Zero tillage Reduced water use , reduce green
house gas emission, more tolerance to
heat stress
Laser aided land leveling Reduced water use, reduced fuel
consumption, reduced GHG emission
Diversification Conserve soil fertility , efficient use of
water
Raised bed planting Less water use, improved drainage,
more tolerance to water stress
Leaf colour chart for N management Reduced fertilizer N requirement,
reduced N loss and environmental
pollution
39
Wassmann et al ., (2009)
Conservation Agriculture improves
 Soil quality
 Reduces soil erosion
 Improves water use efficiency
 Reduces green house gas emission
 Yield
40
 Conservation Agriculture practices conserves and
improves natural resources leading to sustainability
which is not possible in conventional agriculture.
 Conservation Agriculture is site specific and need
based.
41
 Optimization of technology, production and efficiency.
 Development of suitable crop varieties.
 Development of suitable cost effective machines and
equipment's.

  • 5. Conservation agriculture aims to conserve, improve and make more efficient use of natural resources through integrated management of available soil , water and biological resources combined with external inputs. It contributes to environmental conservation as well as enhanced and sustained agricultural production. It can be defined as resource efficient or resource effective agriculture. ( FAO,2008)
  • 6. Population pressure & Unsustainable use of land Severe land degradation and food insecurity so, we have to produce more food from less land through more efficient use of natural resources and minimum impact on environment.
