to evaluate the effects of some phosphorus solubilizing bacteria strains on yield and agronomic traits in local bean (phaseolus vulgaris l.) of guilan, different phosphate fertilizer rates were tested during 2014 growing season. this research was carried out in experimental field of agricultural and natural resource research center of guilan province as split plot arrangement based on randomize...

this study was carried out to determine effects of phosphorus residual applied to wheat on vetch (vicia panonioca) growth, yields and some  soil  physical, chemical  properties in soil. the experiment was conducted with randomized completely block design in a field with three replications including four levels of p residual (applied for wheat p0, p15, p30, and p45 kg p2o5 in hectare) from tripl...

Maize grain yield varies highly with water availability as well as with fertilization and relevant agricultural management practices. With a 311-A optimized saturation design, field experiments were conducted between 2006 and 2009 to examine the yield response of spring maize (Zhengdan 958, Zea mays L) to irrigation (I), nitrogen fertilization (total nitrogen, urea-46% nitrogen,) and phosphorus...

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...

A field experiment was conducted to evaluate the effects of two nitrogen levels (N: 0,100 kg ha -1 ) and four phosphorus levels (P: 0, 60, 90, 120 kg P2O5 ha -1 ) on smooth bromegrass (Bromus inermis Leyss.) seed quality by measuring germination, mean germination time (MGT), protein and phosphorus contents, acid phosphoesterase (APT) and antioxidant enzymes activities, hydrogen peroxide (H2O2) ...

At the Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj, a field experiment was undertaken during Rabi season 2022. The soil texture experimental plot sandy loam, with pH 7.1, low organic carbon (0.28 percent), available N (225 kg/ha), P (19.50 and K (213.7 kg/ha). Rhizobium sp (20g/kg seed), PSB + (10g/kg seed 10g/kg seed) were used as bio-fertilizers, phosphorus (50 kg P2O5/ha, 6...

Serials Li2O–Al2O3–SiO2 matrix glasses and glass-ceramics with different content of P2O5 were prepared by conventional melt cooling method and crystallization process. The effects of P2O5 content on microstructure and properties such as viscosity, melting temperature and coefficient of thermal expansion (CTE) of Li2O–Al2O3–SiO2–P2O5 glasses and glass-ceramics were investigated by DSC, XRD, CTE ...

A field experiment was conducted at R.G.S.C, Banaras Hindu University, Mirzapur, Uttar Pradesh, India during 2016 in kharif season (Sep.-Oct.) The aim to evaluate the effect of different nitrogen, phosphorus and potassium level on fodder production sudan grass (Sorghum bicolor var. Sudanese) for optimization growth yield, crude protein content economics grass. experimental laid out split plot d...

In order to better understand and develop the technology of integrating dephosphorization decarburization in a single converter (abbreviated as IDDSC), relevant thermodynamic issues were discussed by calculation. Based on calculation, bridges between phosphorus distribution ratio, temperature, slag composition constructed. Besides, connections behavior microstructure also established investigat...

Automotive catalysts can be exposed to various poisonous substances that cause physical or chemical deactivation. One of such poisons is phosphorous, which originates from lubricant oils. This study focuses on the phosphorus deactivation Pd/SSZ-13 used as a passive NOx adsorber (PNA). A clear caused by was observed, and it increased increasing content phosphorous. It concluded phosphorous both ...
