This research was conducted to investigate the relationships between soil(organic matter, potassium, phosphorous, sodium, fine gravel, soil texture, EC, lime,gypsum, nitrogen) and environmental (elevation, slope) factors with distribution ofvegetation types in rangelands of Sabzdasht, located in Bafgh, Yazd province at 2012. Forthis purpose, four vegetation types were selected as follows: Artem...

Irrigation with saline water is a possible solution to alleviate freshwater shortages. The long-term use of for irrigation requires consideration the influence salt on environmental conditions soil. objective this field study was determine effects three continuous years physiochemical properties and microbial communities in drip-irrigated cotton fields. total dissolved solid (TDS) levels treatm...

Among different doses of gamma rays, 1.5 kR induced 71.84% callus in Basrnati rice in amodified MS medium and 2% redifferentiation under anon-saline environment, 20% callusing response with 7.5%,2.8% and 2.5% redifferentiation was induced by 2.0 kR at electrical conductivity (EC) of 4,s and 6 dS.m of NaCl respectively, in regeneration medium. A non-irradiated non-saline environment reveale...

Salinity is of significant economic importance in the sugar industry because it affects the growth rate and sucrose yield of sugarcane. The aims of this study were to assess how various aspects of the physiology of sugarcane are affected by increasing levels of soil salinity during the growing season, and to determine whether or not there are differences in the physiological responses of differ...

Salinization is the main characteristic of soils in arid and semi-arid regions which reduce the agricultural potential ofirrigated lands. Therefore, soil reclamation as well as determination of the leaching requirement for salt control is veryimportant for better plant growth. In this study, the effects of leaching on saline soils of Sistan region, southeast of Iranwere examined using unsaturat...

BACKGROUND Skin cancers are the most common cancers around the world. Cutaneous malignant melanoma (CMM) is the malignancy of melanocytes that are mainly located in the skin and mucous membranes. OBJECTIVE This study tried to evaluate the incidence and mean survival time of cutaneous malignant melanoma (CMM) in Yazd, Iran. It seems that the epidemiology and clinical aspects of CMM in Iran are...

Water scarcity and imbalances in irrigation drainage are the main factors leading to soil salinization arid areas. There is a recognized need for effective measures prevent improve saline−alkali land. The principal objective of this project was investigate effects on desalination farmland process improving saline–alkali soils; these included subsurface pipe (SPD) open ditch (ODD). results tests...
