A Field experiments was conducted on sweet sorghum to evaluate the influence of inorganic (chemical ) fertilizer, organics(Vermicompost), Biofertilizers (Azotobactor and phosphate solublising organisms(PSB) and micronutrient (Zn and Fe) on soil properties,green stalk yield, grain yield and various quality parameters of sweet sorghum (Var.HES-04) on Vertisol (Typic Haplustert) at Sorghum Research Station, Marathwada Agricultural university, Parbhani during kharif season of 2005-06. The seven treatment comparised of inorganic fertilizer, vermicompost, biofertilizer (Azotobacter+PSB) and micronutrient (Zn and Fe). The treatment used were T1-100% RDF, T2-50% RDF+vermicompost @ 2.5 Mg ha-1, T3-50% RDF+micronutrients ZnSO4 20 kg ha-1 and FeSO4 25 kg ha-1, T4-50%RDF+biofertilizer (Azotobacter + PSB), T5-T2+micronutrient (Zn+Fe), T6-T2+biofertilizer, T7-T2+biofertilizer (Zn+Fe). The result indicated that the grain yield, green stalk yield and application of vermicompost, biofertilizers alone with 50% recommended dose of fertilizers and micronutrients were found desirable to improve soil health and sustained the productivity in sweet sorghum growth on Vertisol.
