cold stress is one of the most important environmental stresses for rice especially in temperate and high elevation areas. in present study, the effect of different temperatures, as the main plot, including 25 (control), 10 and 5°c on 12 rice cultivars (including champa yasouj, gerde, lenjan askari, kaamfirouz, kohsar, shafagh, domsiya mamassani, dular, gharib, hasan saraei, mosa tarom and 304)...

in order to evaluate the yield and yield components of rice (oryza sativa l. cv. tarom hashemi) in integrated rice, duck and azolla, an experiment was conducted at the research farm of sari university of agricultural sciences and natural resources during 2012. experiment was arranged in split plot based on a randomized complete block design with three replications. the number of ducks as main p...

spiders are the powerful and efficient predators in almost all ecosystems which have effective role in different pest control. the fauna of these arthropods was surveyed during 2005-2009, and their population fluctuations and activities were studied in mazandaran paddy fields in 2005-2006. a total of 53 spider species of 44 genera were collected and identified from paddy fields of mazandaran pr...

Tarom region of Zanjan province is one the olive production centers in Iran, which faced a crisis salinity stress following salinization water resources. The selection tolerant cultivars using pivotal characteristics interesting challenges. This study was conducted to investigate behavior ‘Zard’, ‘Abou-satl’, and ‘Arbequina’ context marginal waters. Therefore, one-year-old self-rooted plants th...

in order to study the effect of different nitrogen fertilizer rates and source-sink limitation treatments on yield and yield component of contrast rice (oryza sativa l.) cultivars, a field experiment was carried out in the rice research institute of iran-deputy of mazandaran (amol) during 2006. a split split experiment in the basis of randomized complete block design with 3 replications and 3 f...

Tashvir and Varmazyar deposits are part of the epithermal ore system in Tarom–Hashtjin Metallogenic Belt (THMB), NW Iran. In both deposits, veins hosted by Eocene volcanic-volcaniclastic rocks Karaj Formation spatially associated with late granitoid intrusions. The assemblages consist pyrite, chalcopyrite, chalcocite, galena, sphalerite (Fe-poor), lesser amounts bornite minor psilomelane pyrolu...
