To investigate the effect of different levels of salinity on yield of three cultivars of cotton, an experiment was performed for two years (2008-2009) as split plot, based on randomized complete blocks design with four replications, at Rudasht Agricultural Research Station, Isfahan Province, Iran. To prepare the salinity levels, mixtures of well water, Zayandehrud river water and drainage water...

within communicative, interactive, and learner-centered framework of language teaching and learning, students need to learn four skills of listening, speaking, reading, and writing for their educational success. but of all the language skills, reading enjoys a paramount significance in so many second or foreign language academic contexts. in spite of its importance, language learners still have...

Arbuscular mycorrhizal fungi (AMF) are widespread endosymbionts in terrestrial ecosystems and their exudates have important effects on soil properties. A greenhouse experiment was conducted with six AMF treatments including four exotic species inoculums (Funneliformis mosseae ,Claroideoglomus claroideum  and Rhizophagus irregularis and a mixed isolate of three species), one mixed native AMF spe...

The current experiment was designed to evaluate the effect of plant growth promoting rhizobactria (PGPR) on chlorophyll fluorescence and some physiological parameters in basil (Ocimum basilicum L.) leaf under salinity stress. The experiment was conducted in factorial arrangement based on completely randomized design. Treatments were four levels of salt stress (0, 40, 80 and 120 mM of NaCl) and ...

In order to study the effects of inoculation of rhizobium and mycorhizae on the response of alfafa cultivars to different salinity levels a pot experiment was conducted. The experiment was arranged as factorial in a randomized complete block design with three replications. The treatments included three alfafa cultivars (Rehnani, Hamadani and Bami), four levels of salinity (0, 60, 120 and 180 mm...
