abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...

One of the most important limiting factors of crop growth in the arid and semi-arid regions is water deficit. Mycorrhizal fungi is one of the most important microorganisms in the rhizosphere. The effects of these fungi apply via changes on some of the characteristics of roots and nutrients uptake in host plants under drought conditions. In order to evaluate the effect of arbuscular mycorrhizal ...

In order to evaluate the effect of seed priming and inoculation of two mycorrhizal species on a number of physiological characteristics, yield and yield components of a wheat cultivar (Parsi) in salinity stress conditions, an experiment was conducted as a split-plot factorial based on a randomized complete block design with three replications in the years 2014-15 and 2015-16 at Isfahan Jihad Tr...

In vitro production is one of the fast and low-cost methods for mass propagation of horticultural crops. But, in vitro plantlets are more sensitive than others and need more adaptation against climatological factors. In order to investigate the symbiosis effects of two species of mycorrhizal fungi on growth and yield of sweet pepper (Capsicum annum L.) cv Inspiration, under drought-stress condi...

The use of plant growth hormones and beneficial microorganisms, could reduce the drought damage. The purpose of this study was to investigate the treatment with salicylic acid and inoculated with mycorrhizal fungi at different levels of irrigation on flax growth. A factorial experiment based on randomized complete blocks design with 3 replications was performed in growth chamber of college of a...

The effect of drought stress and mycorrhizal symbiosis on the colonization, root and leaf phosphorous content, root and leaf phosphatase activity, root volume and area as well as shoot dry weight of a variety of hulless barley were evaluated using a completely randomized experimental design (CRD) with 3 replications. Treatments were three levels of drought stress of 30, 60 and 90% field capacit...
