A study was undertaken in the Khurda district of Orissa to assess the impact of on-farm trials on Rice-based Utera Cropping Techniques on the knowledge level of farmers. The knowledge level of the farmers have been measured by involving three major aspects of integrated management of rice-based utera cropping techniques viz., I) Sowing Time, II) Nutrient Management and III) Improved Cultural Practices. The results revealed that there was a remarkable change in knowledge level of the farmers in all the three aspects of Integrated Crop Management Techniques after exposure to on-farm trials. The pre-exposure mean knowledge level was increased from 20.5% to 89.0% indicating a change of 68.5% in the overall knowledge level of the farmers.
