The objective of this study was to evaluate possible effects mineral fertilizer (NPK), one commercial and three N2-fixing, P-solubilizing and/or ACC deaminase-containing bacteria based bio-fertilizers in triple strains combinations (BF9: Bacillus megaterium 47/9+ Paenibacillus macquariensis RC696 + Pseudomonas fluorescens 9/7; BF10: RC665+ RC382 BF11: simplex RC64 putida 3/10 Burkholderia pyrro...

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...

A experiment was lay out in order to evaluate the effects  of different biofertilizers on yield and yield components of maize at the Lorestan provience, Iran. The experiment was a factorial design with three replications. Treatments were three nitrogen biofrtilizers (Nitrokara (N1), O4 (N2), O6 (N3) and control (N4)) and three phosphate biofrtilizers ...

Struvite precipitation is a simple technology for phosphorus recovery from source-separated urine. However, production costs can be high if expensive magnesium salts are used as precipitants. Therefore, waste products can be interesting alternatives to industrially-produced magnesium salts. We investigated the technical and financial feasibility of wood ash as a magnesium source in India. In ba...

in order to investigate the effects of municipal waste compost and benefit fungi of trichoderma species on seedling emergence parameters, growth and some micronutrients uptake of garden cress a pot experiment was carried out in factorial arrangement based on randomized complete block design with 3 replications. treatments consisted of three levels of municipal waste compost (15, 30, 45 mg ha-1 ...

The aim of this study was to evaluate P availability, P and C contained in the microbial biomass, and enzymatic activity (acid phosphatases and β-glucosidases) in a Nitisol with the application of mineral and organo-mineral fertilizers. The experiment was performed in a protected environment with control over air temperature and soil moisture. The experimental design was organized in a "5 x 4" ...

this research was carried out at agricultural and natural resources research center, isfahan, islamic republic of iran (kabootar abad) for two years (2006-2007). the experiment was conducted as a split plot arranged in randomized block design with four replications. treatments were four levels of n fertilizer [110, (160 = soil and water research institute recommendation), 210 and 260 kg ha-1] a...

Chemical precipitation is a suitable method for the recovery and removal of ammonium in water and a fertilizer known as MAP (magnesium ammonium phosphate; MgNH4PO4.6H2O; struvite) is obtained. Additionally, the advantage of this method is that environmental conditions do not have any effect compared to biological methods. In this study, the recovery of ammonium (Cmean=348 mg NH4 /L ± 38.1; n=25...

in order to study the effect of bio-fertilizers  in decrease the effects of water stress on yield, yield components and oil percentage of goldasht spring safflower cultivars (carthamus tinctorius l.), an experiment on split plot in a randomized complete block design with three replications was carried out  in 2012 at the agricultural research station of islamic azad university of roudehen branc...
