Research Note J.Res. ANGRAU 39(1&2)58-59, 2011 EFFECT OF MANURES, INORGANICS AND BIO-FERTILIZERS ON YIELD, JUICE QUALITY, NUTRIENT CONTENT AND UPTAKE OF SWEET SORGHUM (Sorghum bicolor (L.) Monech ) IN PONGAMIA BASED AGRISILVICULTURE SYSTEM KASTHURI RAJAMANI, M.A. AARIFF KHAN and A. PRATAP KUMAR REDDY Department of Soil Science and Agricultural Chemistry, College of Agriculture, Acharya NG Ranga Agricultural University, Rajendranagar, Hyderabad-500030. A field experiment was conducted during rabi 2008-09 at Agroforestry Research block, Acharya N.G Ranga Agricultural University campus, Rajendranagar, Hyderabad, on sweet sorghum grown in the inter spaces of two year old Pongamia grafts with a spacing of 5 x 4 m. The soil of the experiment site was red sandy loam in texture, neutral in reaction (6.93), non-saline (0.16 dS m -1 ), low in organic carbon (0.41%), available nitrogen (160.85 kg N ha -1 ), phosphorus (10.13 kg P 2 O 5 ha -1 ) and potassium (166.42 kg K 2 O ha -1 ). The experiment consisted of 9 treatments and replicated thrice in a randomized block design. The treatments are: T 1 - Control (without manure and fertilizer); T 2 - FYM 10 ( t ha -1 ); T 3 - 100 percent RDF ( 80-60-40 kg ha -1 NPK ); T 4 - 75 percent RDN + 25 percent N through Vermicompost; T 5 - 75 percent RDN + 25 percent N through FYM; T 6 - 75 percent RDN + 25 percent N through Poultry manure; T 7 - 75 percent RDN + Azospirillum @ 5 kg ha -1 ; T 8 - 75 percent RDN + VAM @ 5 kg ha -1 ; T 9 - 75 percent RDN + Azospirillum + VAM each @ 5 kg ha -1 . Recommended doses of phosphorus and potassium (60 and 40 kg ha -1 ) were applied uniformly to all treatments in the form of single super phosphate (SSP) and muriate of potash (MOP) respectively as basal except Control and FYM 10 ( t ha -1 ). Nitrogen was applied as per the treatments as scheduled in the form of urea in 3 equal splits (1/3 basal, 1/3 at knee high and 1/3 at ear head emergence stage). Plant samples were collected and analyzed at harvest for nutrient concentration and uptake by following standard analytical procedures. Grain yield and stover yield of sweet sorghum were higher, when the nutrients were applied through fertilizers (RDF). More or less similar yields could be realized, when poultry manure was used along with reduced dose of fertilizers. Grain yield of sweet sorghum was on a par with the above, when FYM or VC was applied along with 75% RDF. However, the stover yield decreased significantly when FYM and VC were used as substitutes to fertilizers. Biofertilizers tested viz., azospirillum and VAM were not as effective as fertilizers. The grain yield and stover yield decreased sharply, when part of the fertilizers was substituted with these bio-fertilizers, either singly or combinedly. The results are in accordance with the earlier findings of Kange et al., (2008). The effect of poultry manure on the juice quality of sorghum on the juice quality of sorghum stalks as estimated in the form of brix and sucrose was distinctly evident. The brix and sucrose values were higher with the use of poultry manure. However, the effect of the use of recommended dose of NPK fertilizers was on par with the above. Bio-fertilizers were not effective in influencing the juice quality. The nutrient concentration in the plant tissue and the uptake of these major nutrients by the crop were favourably influenced by the combined use of poultry manure and fertilizers. Higher values were recorded with this treatment. The other organic sources i.e. VC and FYM were less effective when compared to PM. Substitution of fertilizers through bio-fertilizers appeared to be less effective and not to any advantage. The results of the present investigations are in close agreement with the findings of Arbad et al., (2008). Based on the data on grain and stover yield, quality of juice and nutrient uptake, it is evident that integrated use of PM and fertilizers to supply the required plant nutrients to sweet sorghum is a good practice compared to total dependence on fertilizers alone.
