Low level or no use of organic and inorganic fertilizers serious imbalances soil nutrients, depressed potato yields pose accelerated mining native nutrients. Present on-farm studies was undertaken to observe the combined effects FYM compost along with fertilizers, particularly NPSB on production. The experiment comprised seven treatments: No fertilizer, recommended NP (115 kg N 92 ha-1 P2O5), P...

Background: Soybean is an important legume crop that contributes largely to protein and edible oil. The current experimental trial was held study the influence of various phosphorous levels Phosphorous solubilizing bacteria on growth yield attributes soybean [Glycine max. var. Shivalik]. trail conducted sandy loamy soils central plain zone Punjab. Methods: accomplished during Kharif season in y...

Improving the up-conversion efficiency is the key issue in rare earth doped glasses. The quantum efficiency, optical gap, radiative transition rate and lifetimes of excited states are greatly influenced by the optical properties of the host material, ligand field, multi-phonon relaxation processes, impurities, temperature and concentration of rare earth ions. This presentation gives a panoramic...

A field investigation was conducted at Agronomy research farm A. S. (P.G) College, Lakhaoti, Bulandshahr during rabi seasons of 2006 and 2007. The treatments consisted combination four cropping systems viz. chickpea sole (M1), linseed (M2), chickpea+ 2:1 ratio (M3) pigeonpea + 4:2 (M4) in main plots; two irrigations vegetative stages (30-40 days) flowering stage (70-75 (S1) one irrigation (S2) ...

Mn(II) doped P2O5-ZnO-CaO glasses are being characterized by techniques like XRD, UVVisible and different physical properties. XRD patterns in present glasses have confirmed the amorphous nature of glass samples. The optical absorption spectrum exhibited three bands which are characteristic of Mn(II) in distorted octahedral site symmetry., The density is one of the tools to reveal the degree of...

Soils generally contain adequate amount of inorganic and organic phosphorous but most of these remain unavailable to plants. The efficiency of water soluble phosphorus alone is usually low and soluble phosphorus when added to soil along with phosphate solubilizing microorganisms indicates utilization. The presence of soil microorganisms capable of transforming insoluble phosphorus to soluble fo...

In this study, enrichment possibility of apatite-bearing iron ore sample was investigated to obtain and phosphate concentrates, separately. It determined that the raw contains 35.75% Fe 5.36 P2O5. Magnetite from can be enriched with low field strength wet magnetic separators, apatite magnetite residues by flotation. For purpose, ground minus 106 m size then subjected separation following Accor...
