phosphate solubilizing bacteria are a group of plant growth promoting rhizobacteria (pgpr) that increase growth and yield of plant by enhancing insoluble phosphates. in this study, a greenhouse experiment was carried out to investigate the effect of phosphate solubilizing bacteria and phosphorous fertilizer on the yield and chemical components of sesame. this experiment was conducted in factori...

Ginkgo biloba L. is one of the most extensively planted and productive commercial species in temperate areas around the world, but slow-growth is the most limiting factor for its utilization. Fertilization is one of the key technologies for high quality and high forest yield. To better understand the impacts of fertilization on Ginkgo productivity, the effects of fertilization treatments (singl...

The effect of seed inoculation by phosphate solubilizing microorganisms and different levels of phosphorus chemical fertilizer on forage and grain quality of barley (Karoon x Kavir cultivar) was studied in Experimental Farm of College of Agronomy and Animal Sciences, University of Tehran during 2006-2007 growing seasons. Three phosphorus fertilizer levels of 0 (control), 30 and 60 kg ha were al...

Phosphate-rock or more precisely the phosphorites form the repository of phosphate supply for the fertilizer industry for manufacture of elemental phosphorus, phosphoric acid and innumerable alkali phosphates. It has now been universally agreed that phosphorites have some kind of sedimentary marine origin, the source of phosphorous being of organic and/or inorganic origin (1). The principal pho...

abstract fertilizer use efficiency (fue) is one way of improving the fertilizer management in agriculture. in this study, spinach (spinacea oleracea) was used as a case study vegetable to determine its nitrogen use efficiency in varamin, iran. an experiment was conducted using split plot design with three replications. treatments included of five levels of n as 0, 150, 200, 250 and 300 kg ha-1 ...

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 ...

Phosphate fertilizer experiments with nonbearing citrus trees were started at planting time in commercial groves on 5 flatwoods soils. The soils included 1) Brighton peat, 2) Sunniland, 3) Keri-Bradenton, 4) Immokalee, and 5) Immokalee-Pomello. Some of the phosphate treatments were applied only once, as broadcast applications at planting time. Other treatments were applied periodically to indiv...

in order to investigate the effect of various rates of phosphorus fertilizer and efficiency amount of broadcasting and banding methods on yield and yield components of corn (zea mays l.), a field experiment were arranged in a split-plot design based on a randomized complete block design with four replications at the research field, ramin agricultural and natural resources university, mollathani...
