A field experiment was conducted during November, 2015- February, 2016 rabi season at college farm, N.M college of Agriculture, Navsari Agricultural University, Navsari, India to study the Effect of various levels of inorganic fertilizer and vermicompost with and without bio-fertilizer on growth, yield attributes and yield of sweet corn (Zea mays L. Saccharata).The design applied was factorial randomized block design having three factors with two levels of inorganic fertilizer @ 75% RDF, 100 % RDF, three levels of vermicompost 0, 2.0 and 4.0 t/ha and two levels bio fertilizers control and Azospirillum + PSB respectively. The result shows growth parameters viz.; plant height was influenced significantly by the impose of various levels of inorganic fertilizers. Significantly the highest plant height (85.43 and 184.40 cm) was recorded with 100% RDF (F₂) during 45 DAS and at harvest respectively. The days to 50 % silking of sweet corn was non-significantly influenced by various levels of inorganic fertilizers. The yield attributes viz., number of cobs per plant, cob length, cob girth, test weight, green cob yield and green fodder yield were influenced significantly by the impose of various levels of inorganic fertilizers. Significantly the maximum number of cobs per plant (2.11), cob length (18.98 cm), cob girth (16.03 cm), test weight of 100 grains (16.72), green cob yield (13138.72 kg/ha) and green fodder yield (188.87 q/ha) were recorded with 100% RDF (F₂) which was found significantly differ from the 75% RDF (F₁) treatment. The different level of vermicompost had significant effect on plant height and day to 50% silking. Significantly the maximum plant height and minimum days to 50% silking was recorded with vermicompost @ 4.0 t/ha (V₂) followed by vermicompost @ 2.0 t/ha (V₁). The yield attributes viz., number of cobs per plant (2.29), cob length (19.28 cm), cob girth (16.65 cm), test weight of 100 grains (18.13), green cob yield (14151.75 kg/ha) and green fodder yield (199.79 q/ha) were influenced significantly by different level of vermicompost. The vermicompost @ 4.0 t/ha (V₂) recorded the maximum number of cobs per plant, cob length, cob girth, test weight of 100 grains, green cob yield and green fodder yield. Application of biofertilizer had non-significant effect on most of the growth parameter, yield attributes and yield.
