Abstract

A field experiment was conducted on Typic Haplustert at Research Farm, Marathwada Agricultural University, Parbhani (M.S.), India in rainy season of 2005-06. The soil was slightly alkaline (pH 8.2) and low in available N (231 kg ha^-1) and moderate in availability of P₂O₅ (15 kg ha^-1) and high in K₂O (472 kg ha^-1) having DTPA extractable Zn and Fe 0.79 and 4.29 mg kg^-1, respectively. The experiment was laid out in Randomized Block Design (RBD) with seven treatments replicated thrice. The sweet sorghum variety used was HES-04. Inorganic fertilizers were applied as per recommended dose of fertilizer and micronutrients as per treatment through chemical fertilizers. However, Azotobacter and phosphorus solubilizing bacteria (PSB) were used for seed treatment before sowing. Vermicompost was applied @ 2.5 Mg ha^-1 as per treatment at the time of sowing. Green stalk and grain yield, chemical analysis, Juice extraction, total soluble solid (°Brix), reducing and non-reducing sugars were determined at physiological maturity using standard procedures. The grain and green stalk yield of sorghum was significantly improved by application of inorganic fertilizers @ 50% RDF+vermicompost and micronutrients (Zn and Fe) along with seed treatment of biofertlizers. Similarly, addition of micronutrients also has contributed in increasing yield of crop. Quality of sweet sorghum in terms of juice extraction (%), °brix, reducing and non-reducing sugar was also found to increase with different integrated management practices particularly with application of 50% RDF+vermicompost+biofertilizer along with micronutrients. Comparatively higher nutrient concentration of NPK in grain and stover was found in 50% RDF along with micronutrients and Fe and Zn in stover was found higher in same treatment.

Abstract

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).

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.

Abstract

The experiment was conducted in pot conditions at the Department of Agricultural Chemistry and Soil Science, College of Agriculture, Parbhani from 12 October 2005 to 3 January 2006, in order to study release the pattern of water soluble sulphate sulphur through different sulphur sources at periodic intervals in vertisols. In the incubation study, the water soluble sulphate sulphur was increased due to addition of various sources of sulphur. Water soluble sulphate sulphur increased upto 56 days in Vertisols and gradually decreased there after. Out of four sources tried S-90 (T₁) released water soluble sulphate sulphur to the maximum followed by SSP, gypsum and elemental sulphur.
