An experiment was carried out during rabi season 2011 at Post Graduate Centre, University of Horticultural Sciences, Campus, Gandhi Krishi Vignana Kendra, Bangalore to study the effect of integrated nutrient management on growth, yield and quality of potato (Solanum tuberosum L.). Application of 50% RDF + 50% FYM + Azotobacter + Phosphobacteria recorded maximum plant height (77.76 cm), number of leaves plant-1 (103.65), number of stems plant-1 (9.11), stem girth (3.74cm), fresh weight accumulation (2.01 kg plant-1), dry weight (255.3 g plant-1), number of tuber plant-1 (7.87), total tuber yield ha-1 (34.14 t ha-1), tuber dry matter (21.67%), starch content (78.20%) and total sugars (1.74%) which was on par with T4 and T3. The maximum net income per hectare (282909 Rs.) was recorded in plants provided with 50% RDF + 50% FYM + Azotobacter + Phosphobacteria (T7 ) and the highest benefit: cost ratio (1:2.25) was recorded in plants provided with STCR targeted yield (T3 ).
