in order to evaluate the effect of using zinc granulated phosphorous biofertilizer on yield and yield components of white bean (phaseolus vulgaris l.), a field experiment based on a randomized complete block design with three replications was performed. experimental treatment were included of using phosphate and triple super phosphorous chemical fertilizer at five levels (without using of chemi...

The application of zeolite to soils increases cation exchange capacity, and as increases nutrient retention capacity. Imbalanced nutrient management is one of the reasons responsible for low yield of potato in Iran. This study was carried out in research field of Islamic Azad University; Arak Branch at central of Iran to evaluate effect of zeolite particles and phosphorus fertilizer on agro-phy...

Recent human population increase has been enabled by a massive expansion of global agricultural production. A key component of this "Green Revolution" has been application of inorganic fertilizers to produce and maintain high crop yields. However, the long-term sustainability of these practices is unclear given the eutrophying effects of fertilizer runoff as well as the reliance of fertilizer p...

introduction: citrus are one of the important orchard fruit production that after banana is second in production at the world level and every year, chemical fertilizers having most important role in increasing crops productions, but in long application of fertilizers cause soil destructions and polluting underground water. also soils of dry regions are very poor in organic matter level. nowaday...

to investigate the effect of on-farm seed priming and arbuscular mycorrhizal fungi in different amounts of phosphate fertilizer on emergence, yield and yield components of a semi-mid maturity corn hybrid (es-sensor), an experiment was conducted at the research station of agriculture college, bu-ali sina university in 2012 in a factorial randomized complete block design with three replications, ...

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...

most plants are able to increase soil phosphorus availability by exuding some compounds such as organic acids when they experience phosphorous deficiency. considering this special ability of plants, the main purpose of the present research was to investigate if application of organic acids may increase p availability in soil. therefore, a greenhouse experiment was conducted with five treatments...

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 ...

in order to study the effect of on-farm seed priming and two bio-fertilizers on emergence and yield characteristics of chickpea, a factorial experiment was conducted in a randomized complete block design in hamedan with three replications in 2013. the factors consisted of phosphate fertilizer (0, 50 and 100 percent of recommended) bio-fertilizer (mycorrhizae, barvar2, both of them and no-applic...
