Technological innovations in CA Machinery : How can policymakers support engineers?

• Supporting/Enabling elements – Declining Farmers income, Labour Shortages, Degradation of Natural Resources (Soil, Water & Environment), Climate Change & Sustainability of Agriculture

• Challenges – Land Holding, Economic Condition, seasonal use , size & shape of Fields, terrain, machine v/s Labour and mind set (CA Course)

Mechanization & CA

Conservation Agriculture

Three Principles

• Minimum Disturbance

• Soil Cover with residue

• Crop Rotation

Three Benefits

✓ Enhanced Productivity

✓ Richer Resources

✓ Climate Adaptation

<<<<<<<<<< Choosing Directions >>>>>>>>>

•System Approach & Un-sustainability can not be the option

•It need to be biophysically and socio-economically sustainable.

•Sustainability also demands confronting climate change

Can We marry CA and PW&NM using SSD ?

• Minimize Surface Evaporation

• Improved WUE

• Easy Mechanical operations

• Effective fertigation – Better NUE

• reduce the volatile losses of NH3

• minimize immobilization in surface residues

• May be Less Weeds & More Drip line life

• Possibility of Automation

Wheat on permanent beds with Sub Surface drip in Maize-wheat System

Direct seeded Wheat after Direct seeded Rice with Sub Surface drip in Rice -wheat System

Enhancing Water and Nitrogen Use efficiency through fertigation in Maize Wheat and Rice Wheat system using Sub Surface drip (SSD) irrigation under Conservation Agriculture

• Fertigation using SSD saved 25% of fertilized N in both Maize and wheat without any yield penalty

• Irrigation water productivity increased by about 150 and 100% in maize and wheat, respectively

• Saving of 20% fertilizer N and increased irrigation water productivity by about 60-80% in rice with similar yields

• Increase in wheat grain yield and irrigation water productivity by 10 -20% and 30%, respectively.

Barriers to Wider adoption

• Mind set (undoing conventional Agriculture)

• Preachers and Practitioners

• Conflicting Messages & policies

• Short term / Long term gain v/s risk

• Ability of the farmer to take risk & no incentive

• New Set of Machines & Knowledge Intensive

• Few Custom operators

How Policy Can Support Engineers

• Avoid Policy Mismatch

• Encourage Farmer and Environment Friendly Innovations with proper knowledge dissemination and effective trainings

• Criteria of Promotion for a machine should be linked with environmental /soil health benefits

• Forceful implementation or willful adoption

• Strong policy support -Turning Agriculture Waste into Wealth – with wide publicity

• Innovative business cases for scaling and Win Win for all

• CA - Sacred service to save environment, water, soil health with more net returns
