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 treatments comprised of inorganic fertilizer, vermicompost, biofertilizer (Azotobacter+PSB) and micronutrient (Zn and Fe). The treatments 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 juice percentage was significantly highest in treatment T7 (50% RDF+vermicompost @2.5 Mgha-1+biofertilizer) and statistically at par with T5 (50% RDF+vermicompost @2.5 mg ha-1+micronutrients).

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 treatments comprised of inorganic fertilizer, vermicompost, biofertilizer (Azotobacter+PSB) and micronutrient (Zn and Fe).
