A field experiment was conducted at Research Farm of ICAR Research Complex for NEH Region, Nagaland Centre, Medziphema during 2010 and 2011 to study the effect of different sources of organic manures and inorganic fertilizers on productivity, profitability of rice and soil health in Eastern Himalayan Region on a sandy loam soil. Among the organic sources of nutrient poultry manure (2.5 t ha-1) was found to be the best in terms of productivity, profitability and soil health. The results showed significant improvement in all yield attributes and yield (5.6 t ha-1) as well as nutrient uptake and crop profitability (` 340.73 ha-1day-1) due to the application of 2.5 t ha-1 of poultry manure along with 60-13.1-25.0 kg ha-1 N, P and K fertilizers over other treatments. The same treatment recorded highest net energy output (184.20 x 103 MJ), benefit cost ratio (2.66) and had significantly improved in soil organic carbon, nitrogen, phosphorous and potassium content of soil after harvest of the crop.
