This study has evaluated the technical efficiency of farmers engaged in rice-wheat cropping systems in northeastern India who are using resource-conserving technologies (RCTs) such as zero tillage (ZT) and direct-seeded rice (DSR). These technology promotions are being carried out under the intervention of the Cereal Systems Initiative for South Asia (CSISA) project, primarily funded by the Bill & Melinda Gates Foundation. The RCTs are being promoted as part of conservation agriculture supported by the project. The data used in this study have been derived from the socioeconomic surveys conducted in Eastern Uttar Pradesh and Bihar in northeastern India during the kharif season of 2009 and the rabi season of 2010. A stochastic frontier analysis was carried out to investigate and compare the determinants of technical efficiency among farmers receiving intervention and those who are not. The study revealed that farmers receiving CSISA intervention have realized higher levels of technical efficiency. Additionally, farmers who are receiving subsidies and farmers who are planting more diversified crops have higher levels of technical efficiency
