Study area was selected from Talou farm to Chahjam Kavir in Damghan. Several plant types were distinguished in mentioned site. The types were Artemisia herba alba-Pteropyrum olivieri, Anabasis aphyllaLycium depressum, Tamarix. spp.-Halocnemum strobilaceum, Ha. strobilaceum Halostachys bellangeriana, Ha. strobilaceum-Limonium iranicum. In each plant type, three dominant plant species were select...

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...

To determine salt sensitivity for wheat at various growth stages, a factorial experiment arranged as randomized complete block design was conducted in the ambient environment at the National Salinity Research Center, Yazd, Iran. Treatment were two cultivars of wheat (Kavir & Roshan) and salinity imposed at emergence, tillering, stem elongation, spike emergence and one week after anthesis. A con...

The effect of seed inoculation by phosphate solubilizing microorganisms and different levels of phosphorus chemical fertilizer on yield and yield components 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. The experimental treatments were arranged in split plot factorial based ...
