Rice (Oryza sativa L.) productivity is a major concern under rain-fed agriculture. Due to lack or inadequacy of knowledge on modern agricultural practices and technology, smallholder and marginal rural and tribal farmers do not conduct improved agronomic practices. As a result, rice grain yield is low and food scarcity at household level is conspicuous. This study emphasized the impact of Integrated Nutrient Management (INM) and Integrated Pest Management (IPM) on rice productivity in tribal villages of Koraput district, India. Participatory rice yield enhancement trials for three rice varieties namely Khandagiri, MTU–1001 and Ramachandi were conducted in 21 villages with 47 farming families. Simultaneous field trials highlighting farmers’ or traditional and improved practices were carried out to train farmers. After one growing season that is Kharif, yield and agronomic variables were recorded. Results indicated that the upland rice responded very well to the management practices followed by lowland and medium land rice in that descending order.

Key words: Integrated nutrient management, integrated pest management, smallholder and farmers, yield.
