In this GGA study, electronic and magnetic properties were investigated with the implementation of the FP-LAPW method within the framework of DFT. Resulting compounds Ag0.125Sr0.875O and Au0.125Sr0.875O were formed by substituting transition metal atoms silver and gold in strontium oxide with 12.5% concentration. Formation energy values show the compounds are stable in the ground state. Volume optimization curves predict the doped compounds are stable in the ferromagnetic phase. Total DOS and band structure plots display half-metallicity at the Fermi level, and also magnetic moment was found in the supercells. [ABSTRACT FROM AUTHOR]

Field experiments were carried out at Mountain Livestock Research Institute (MLRI), Manasbal, Sher-e-Kashmir University of Agricultural Sciences and Technology Kashmir, India to study the direct and residual effect of different rates of organic and chemical sources of nutrients on fodder sorghum-fodder oat cropping sequence during Kharif 2008, 2009 and rabi 2008-09, 2009-10. Application of FYM @ 25tonnes recorded higher green fodder yield of sorghum than rest of treatments. The physical optimum dose of direct+residual effect of FYM on fodder sorghum-fodder oat sequence was 25.49 t ha-1 and economic optimum dose 12.63 t ha-1. Applying 120, 80 and 30 (N, P2O5, K2O kg ha-1) was found superior in green fodder yield than rest of treatments. However, physical optimum dose due to direct +residual effect of N, P2O5 and K2O on fodder sorghum-fodder oat was 134.19, 67.07 and 33.54 kg ha-1 and mean total economic optimum dose was found to be 128.0, 64.19 and 32.62 NPK kg ha-1 respectively.
