in order to evaluate the efficiency of plant growth promoting rhizobacteria (pgpr) plus nitrogen and phosphorous chemical fertilizers on relative agronomic efficiency of p and n fertilizers and some agronomic parameters of wheat (triticum aestivum l.) cultivar n-80-19, an experiment was conducted at sari agricultural sciences and natural resources university during growing season of 2008-2009. ...

Biofertilizers are cheap, eco-friendly, improve soil fertility and plant nutrition within short time, effective components in organic farming. The present field study was carried with eight treatments to the effect of Azospirillum, Phosphobacterium AM fungus their combination on primary growth characters coriander. experiment conducted a factorial randomized block design. collar diameter, heigh...

The application of microbial inoculants (biofertilizers) is a promising technology for future sustainable farming systems in view of rapidly decreasing phosphorus stocks and the need to more efficiently use available nitrogen (N). Various microbial taxa are currently used as biofertilizers, based on their capacity to access nutrients from fertilizers and soil stocks, to fix atmospheric nitrogen...

to evaluate the effects of fertilizing and deficit irrigation regimes on some chemical properties of soil and plant, an experiment was conducted during 2007 and 2008 growing seasons. experimental design was a split plot based on a randomized complete block design with four replications. the treatments consisted of three deficit irrigation regimes (main plots) and six soil fertilizing systems (s...

BiofertiJizers are microbial preparations containing living cells of different microorganisms which have the ability to mobilize plant nutrients in soil from unusable to usable form through biological process. They are environmental friendly and play significant role in crop production. Previollsly it is mainly used for field crops but now-a-days it is used for fruit crops also. Biofertilizers ...

In this study the effect of four levels of nitrogen fertilizer (0, 50, 100, 150) kg/ha and four levels of super phosphate triple (0, 50, 100, 150) kg/ha were investigated on Rubia Inctorum L. (madder) under salinity stress. A factorial experiment was carried out in a research farm in Roaddasht, Isfahan based on complete randomized blocks with three replications. The results of the variance anal...

Continuous decline of earth’s natural resources and increased use hazardous chemical fertilizers pose a great concern for the future agriculture. Biofertilizers are promising alternative to gaining importance attaining sustainable play key role in increasing crop yield maintaining long-term soil fertility, which is essential meeting global food demand. Microbes can interact with plants enhance ...

the effect of different fertilizing systems and drought stress during grain development on grain minerals of barley (hordeum vulgare l.) was studied in field experiments on a clay-loamy soil during 2007 and 2008 growing seasons. the treatments consisted of three irrigation regimes (main plots) of: non-stressed (ns, normal irrigation continued until the end of plant physiological maturity), ...
