Challenges for Food Security
Exploding population – little control / No control
Harvested area shrinking (?)- crop intensification
Greater competition for land, labor and watergood land diverted to other sectors
Increasing production costs
Climate change more apparent – terminal heat,
rusts etc.
Resource fatigue - Reducing factor productivity,
land degradation
‘One size fits all’ approach and untrained
extension staff.
Issues Realized And Solutions
Issues

Meeting the Food Security Challenge
Conservation Agriculture (CA) is now a
globally accepted agro-ecological approach to
sustainable intensification of crop production.
CA comprises resource conserving agricultural
production practices that aim to produce more
at less costs while enhancing the quality of the
natural resource base.
CA is all about generating multiple options for
farmers who are endowed differentially.
Conservation Agriculture Means Dramatic
Tillage Reductions Combined with Adequate
Surface Retention of Crop Residues

Zero Tillage – A cost effective and input
use efficient technology
Advantages of Zero Tillage
Zero Till (ZT) –Wheat Seeding
• Reduced costs (Rs 20002500/ha) due to savings in fuel
and labor
• Timely planting of kharif and
winter season crops, resulting
in higher yields
• Lower density of herbicide
resistance in comparison to
traditional tillage.
• Significant
irrigation
water
savings (up to 15-20%)
• Improved input use efficiency
because of the right placement
of seed and fertilizer nutrients
• Better plant stands
• Less burning of crop resides

Rotavator : An emerging issues
Increased seed rate (160 kg/ha)
Promote sowing by broadcasting the seed
Enhanced weed problem of Phalaris minor/ other weeds
Use of Rotavator - soil compaction - symptomatic problems crop lodging and water logging /chlorosis
Farmers have to apply additional N / P to overcome yellowing
Low productivity (less tillering, small earhead & grain size and
low grain weight )
Rotavators donot operate in presence of residues 4-5 T/ ha
Rotavator use promote burning of crop residues.
Rotavator use need to be Banned
