Technical efficiency of resource conserving technologies in rice wheat system: case of Bihar and Eastern Uttar Pradesh in India

Abstract

This study aimed to evaluate the technical efficiency of farmers engaged in rice-wheat cropping systems in India using Resource Conserving Technologies (RCTs) such as zero-tillage and direct seeding, under the intervention of the Cereal Systems Initiative for South Asia (CSISA) project primarily funded by the Bill and Melinda Gates Foundation. The goal of the project is to alleviate hunger and malnutrition as well as increase income and food security for poor farmers living in South Asia. The Resource Conserving Technologies (RCTs) are being promoted as part of conservation agriculture supported by the project. These technologies are designed to reduce the strain agricultural production has on two critical natural resources: water and soil. The RCT technologies are being promoted by the CSISA project in several locations in India, and the main ones are direct seeded rice, reduced-tillage, and zero-tillage. The farmers participating in the study are part of the CSISA project and are located in Eastern Uttar-Pradesh and Bihar in Northeastern India. The data used in this study was derived from a socio-economic survey conducted in these two regions during the Kharif season of 2009 and Rabi season of 2010. A Stochastic frontier Analysis, using the Cobb-Douglas or Translog function form, was performed to investigate and compare the determinants of technical efficiency among farmers receiving intervention and those who are not. Farmers receiving intervention from the CSISA project tend to be more technically efficient than those without intervention.
