in order to investigate the effect of different levels of biofertilizer inoculation and phosphorus chemical fertilizer on mineral elements absorption in forage corn sc. 540 under humidity regimes, an experiment was conducted as line source based on a randomized completele block design with three replications during two growing seasons of 2012 and 2013. the implementation of line source was appl...
Pig farming produces more manure than can reasonably be spread onto surrounding fields, particularly in regions with high livestock densities and limited land availability. Nutrient recycling offers an attractive solution for dealing with manure excesses and is one main objective of the European commission-funded project “BioEcoSIM”. Phosphate salts (“P-Salt”) were recovered from the separated ...
in order to study the effect of fertilizer management on summer savory production, a field experiment was conducted at the agricultural research station, college of agriculture, ferdowsi university of mashhad, iran during growing season of 2009. a randomized complete block design with three replications was used. treatments included: 1) nitroxin biofertilizer 2) phosphate solubilizing bacteria ...
Due to the excessive use of chemical fertilizers and also the lack of adequate information on the growth responses of ornamental plants to bio-fertilizers and municipal solid waste compost, this investigation was carried out on Zinnia. Therefore, a field experiment was conducted in complete randomized block design with three replications. Fertilizers included municipal solid waste compost, phos...
A pot experiment was carried out on hybrid drumstick PKM 1 added with inorganic and organic fertilisers. Seeds of hybrid Drumstick PKM1 were sown in the plastic pots in glass house condition. Single inorganic fertilizer, phosphate solubiliser and bio organic fertilizer as well as in different combinations were applied to the pots. Data revealed that plant height, fresh and dry biomass, moisture...
In order to study the effects of phosphate biofertilizer Barvar 2 and triple super phosphate fertilizer on yield, quality and nutrient uptake in Medicago scutellata, cv. Robinson, a field research work was done in the Research Field of Agricultural College, Shahed University, located in Tehran, Qom highway in 2006. The treatments included phosphate biofertilizer Barvar 2 at two levels including...
In the present study, the amount of nitrate and phosphate leaching from agricultural lands into the Zanjanrood River in Iran was simulated using the Soil & Water Assessment Tool (SWAT) model. The measured average monthly discharges at the Sarcham station were used to calibrate and validate the SWAT model, and the SWAT Calibration and Uncertainty Program (SWAT-CUP) model was applied to perform t...
