CSISA-Objective 2 Outline • Background – Thinking • Activities 3. Site of Action, CS Targets 4. Experimental Platform – Design 5. Performance Target Indicators
CSISA-Objective 2 Crop and Resource Management Practices for Sustainable Future Cereal Based System • Conservation Agriculture/RCT • Ecological Intensification
Conservation Agriculture (CA) • CA promotes minimum disturbance of soil by zero or reduced tillage, balanced and crop need based application of chemical inputs, and skilful management of crop residues and wastes. Ecological Intensification (EI) • Evidence-based process of identifying best management practices for innovative crop production systems through high-quality scientific research and participatory evaluation. • Measurable indicators and corresponding reference values for productivity; profitability, resource efficiency, sustainability, ecological resilience and environmental performance.
Underlined Assumption • Conservation tillage with other best practices can help meet the food demand, protect the environment and provide income to the farmer.
Integrated Crop and Resource Management “Ecological Intensification” Crop Management NRM Conservation and efficient use of natural resources Productivity with optimal external inputs Variety Fertilizer Pesticides Labor Energy • Land • Leveling • Tillage / CE • Residue • Water • Climate Conservation Agriculture
CSISA: Target Crop Rotations (8.05 Mha)
Objective 2: Activities 2.2 Analyze and design principal choices for cereal systems and their management and breeding targets 2.3 Process research to design next generation of cereal system and long-term analysis – Experimental Plaform 2.4 Long-term performance analysis 2.5 Assessment of opportunities for livestock integration 2.1 Participatory adaptation and improvement of new technologies (those not yet ready for large scale dissemination).
CSISA Objective 2.1 & 2.2 Minimally-tilled Dry Drill-Seeded Residue-Mulched Cereal Production System that are Efficient in Labor, Water, Energy, and N Fertilizer use Land Preparation / Crop Establishment System Tailored Genotypes Pest Management Residue Management Adaptation & improvement of ICRM/CA System Nutrient Management (SSNM) Water Management
CSISA- Experimental Platforms • Timeframe: 10 years, with short- and medium-term objectives • Few but innovative, forward-looking food or food & energy production systems • High cropping intensity: 2 or more crops/year • Production scale technologies: large plots • Follow conservation agriculture principles and develop new ones • Full integration of elite germplasm • Dynamic best management practices • High-quality measurements • Multi-disciplinary teams • Capacity building

EM Survey EM 31 • Under normal condition • Highest conductivity readings represent high clay content and low drainage • Elevated reading indicate potential saline condition • Low conductivity readings indicate relatively coarse textured soils and good drainage EM 38
EM Survey: Karnal • Karnal Research Platform • Total survey area: 3.6 ha • Three management zones • EM38- horizontal and vertical;and EM 31-horizontal conducted • Conductivity range: 12 mS/m to 123 mS/m • Good correlation between EM 38 and EM 31 • North-western part has not been reclaimed and had high EM values • Total area was divided in 4 EM zones • Soil Samples upto 2 m depth collected from all zones • Analysis will be conducted at IRRI India central laboratory in Modipuram
Cereal Systems Initiative for South Asia Objective 2 Experimental Platform Major Activities: • Developing crop and resource management practices for sustainable future cereal based systems • Evaluating Weed Management Solutions For Zero Till Direct Seeded Rice • Systems and Nitrogen Use Efficient Crops to Reduce Greenhouse Gas Emissions in South Asia • Evaluation of rice varieties/hybrids under zero till and mechanized direct seeded condition
