biofertilizer is a substance which contains living microorganisms which can use instead of chemical fertilizer in sustainable crop production. the effects of phosphate solubilizing bacteria; root endophytic fungi (ef) piriformospora indica, and arbuscular mycorrhizal fungus (amf) glomus mosseae on growth and nutrient uptake of sunflower plants grown in mixture with two clover species, persian c...

Nonpoint-source pollution from agricultural activities is currently the leading cause of degradation of waterways in the United States. Applying best management practices to flood-irrigated mountain meadows may improve agricultural runoff and return flow water quality. Prior research has focused on fertilizer use for increased hay yields, while few studies have investigated the environmental im...

ABSTRACT- To investigate the effects of bio-chemical and organic fertilizers on yield and seeds NPK contents of pumpkin (Cucurbita pepo var. styriaca), an experiment was conducted at the Research Farm of Kurdistan University in 2009 growing season. Treatments were included 1) control, 2) seeds inoculated with free-living N fixing bacteria (NFB), 3) seeds inoculated with phosphate-solubilizing b...

in order to study the combined and separate effects of phosphorus fertilizer, phosphate-solubilizing bacteria and mycorrhizal fungus on adjusting and reducing the loss of yield resulting from drought stress during the stage of growth of grain corn (sc704) an experiment was performed in aboureihan campus of the university of tehran, iran, during 2007-2008. the experiment was conducted as split p...

A greenhouse pot experiment was conducted to evaluate the effect of phosphorous (P) fertilizers application to an alkaline calcareous soil on the water use efficiency (WUE) of lettuce cultivar "robinson" of iceberg type. Head fresh and dry weights, total water applied and WUE were affected significantly by the P fertilizer type and rate. P fertilizers addition induced a significant enhancement ...

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...

   A biological experiment was carried out for the purpose of knowing effect type organic matter, source and level phosphorous on growth yield corn (Zea mays L.) in gypsum soil.  The one agricultural fields Salah al-Din Governorate / Al-Alam district year 2019. study included three factors (type fertilizer, level).  factor fertilizer (not adding Z, compost K sheep waste S), ...

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" ...
