Abstract: The effect of different levels of integrated nutrient sources and bio-fertilizers on growth, yield and quality parameters of sweet potato 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 growth parameters studied like vine length at 60, 90 DATP and at harvest (78.98 cm, 120.17 cm and 175.87 cm, respectively) and the highest number of leaves at harvest i.e. 138.80 per vine. Both of these characters were at par with T3 treatment (50 % RDN through inorganic fertilizers + 50 % RDN through FYM). Highest total and marketable tuber yield per hectare (34.47 t and 32.67 t, respectively) and yield attributes viz., number of tuberous roots per vine (5.10), fresh weight of tubers per vine (0.512 kg), tuber girth (15.94 cm) and tuber length (24.34 cm) were recorded significantly highest in T2 treatment and were also at par with the treatment T3. The marketable tuber yield per hectare recorded 21.81 % increase in T2 treatment over the lowest yield noted in T1 treatment. Application of different nutrient sources did not show significant influence on any of the quality parameters recorded. The application of bio-fertilizers also gave significantly the highest results for 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 biocompost along with combination of bio-fertilizers (T4B1).
