Soil types 4. Seasons 5. Temperature 6. Farm typology 7. Natural resource availability Generally no single strategy works for India However, to identify common strategic point was the main objective Ecological intensification (EI) is a term that has been used to describe a production system that “…satisfies the yield goals as per the environmental quality

- 14. Nurturingdiversity,resilience,livelihood &industrialinputs Conclusion There is no single startgey works for all ecology and farm typology Technology yield gaps depends on the farmer awareness, input availability and ecological conditions. Intra-state variability needs to be addressed with site specific technology Common strategic points to address the yield gaps needs to be identified and advocated for diverse conditions. There is need of location specific component technology targeting at farmers field in order to bridge the yield gap in maize systems.
