ABSTRACT A field experiment was conducted at Research Farm of ICAR Research Complex for NEH Region, Nagaland Centre, Medziphema during 2010 and 2011 for “Enhancement of Rice Productivity, Profitability, Carbon budget and Soil fertility through Integrated Nutrient Management” in Eastern Himalayan Region on a sandy loam soil. Among the organic sources of nutrient poultry manure (2.5t/ha) was found to be most profitable in terms of productivity, profitability and sustaining soil health. The results showed significant improvement in all yield attributes and yield (6.03 t/ha) as well as nutrient uptake and crop profitability (Rs.366.28 /ha/day) due to the application of 2.5 t/ha of poultry manure along with 75-16.5-31.3 kg/ha N, P and K fertilizers over other treatments. The same treatment recorded significantly improved in soil organic carbon, nitrogen, phosphorous and potassium content of soil after harvest of the crop. However, highest cost benefit ratio (2.76) was recorded in the incorporation of 5 t/ha of Dhaincha (Sesbania aculeate) along with 75-16.5-31.3 kg/ha N, P and K over other under the study. Key words: Rice productivity, profitability, carbon budget

Keywords: Rice productivity, profitability, carbon budget
