Abstract: The effect of different levels of integrated nutrient sources and bio-fertilizers on growth, yield and quality parameters of elephant foot yam was evaluated at RHRS farm Navsari, Gujarat. The application of 50 % RDN through inorganic fertilizers + 50 % RDN through vermicompost (T2) had shown significant impact on most of the parameters studied like plant height (73.02 cm and 78.87 cm), canopy spread E-W (88.17 cm and 90.27 cm) and N-S (88.87 cm and 89.82), and number of leaflets per plant (362.07 and 318.90) which recorded maximum values given in the brackets at the age of 120 and 150 DAP, respectively. These values were statistically remained at par with T3 treatment. Yield and quality attributes viz., harvest index (51.77 %), fresh corm weight (1.267 kg) and yield per hectare (26.37 t) were recorded highest with treatment T2 and were also on par with T3 treatment while the starch content was highest (16.57 %) in T3 treatment. The application of bio-fertilizers also gave significantly the highest results for the all the parameters discussed with respect to organic and inorganic sources application. The treatment which received 50 % RDN through FYM along with combination of bio-fertilizers T3B1 realized highest benefit: cost ratio followed by the treatment receiving 50 % RDN through vermi-compost along with combination of bio-fertilizers (T2B1).
