2. Exploding population – little control / No control Harvested area crop intensification Harvested area shrinking (?)- crop intensification Greater for land, labor and water- good land diverted to other sectors Greater competition for land, labor and water- good 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. Challenges for Food Security

3. Issues Realized And Solutions Poor quality seed Use of quality seeds IssuesSolution Weed infestationIntegrated weed management Spray techniques and equipment Timely availability of suitable spray equipments and proper use of spray techniques Low tendency of herbicide use Popularize and change in mind set for appropriate herbicide use Water shortagesGW development, save water, reduce evaporation, weed control Poor land leveling Precise leveling of lands

4. Machinery problem (operational) Machines perfections: For loose residue situations Supply of improved quality machines Diversification of R-W system Adequate irrigation facilities and community approach for diversification IssuesSolution

5. 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. Meeting the Food Security Challenge

6. Conservation Agriculture Means Dramatic Tillage Reductions Combined with Adequate Surface Retention of Crop Residues Conventional Till Systems CA Zero Till Systems

7. CA is Enhanced by Diversified, Economical Crop Rotations

8. Properly Managed CA Encourages Sustainable Soil Management Physical Soil Quality Chemical Biological Soil Organic Matter

9. Conservation Agriculture enhances biological tillage instead of mechanical tillage

12. CA based RCTs options for System sustainability Zero tillage Paired row ZT Control traffic ZT Direct seeding Unpuddled transplanting Reduced tillage Bed planting Surface seeding

13. Zero Tillage – A cost effective and input use efficient technology

14. Zero Till (ZT) –Wheat Seeding Reduced costs (Rs 2000- 2500/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 Advantages of Zero Tillage

15. Permanent FIRB (Residue managed) RiceWheat Mungbean

16. 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

17. CA Planters for Small-Scale Farmers

19. Helps early sowing Saves water, labor and diesel Increases fertilizer use efficiency Reduced soil erosion Improves soil organic C No-tillage is a win- win technology

20. No-till wheat is more tolerant to abrupt temperature rise: Climate change adaptation Conventional RCTs can help Agriculture in Beating the Heat

21. Zero-tillage Zero-tillage with controlled traffic Zero tillage paired row ( 5% more yield gain) Bed planting – saves seed, water and labor, improves grain quality and Yield. Improved Technological options for wheat
