Population development of Tylenchulus semipenetrans in dry soil was investigated in a greenhouse study. Citrus seedlings were grown in sandy soil in vertical tubes with upper and lower sections. Nematode population densities in the upper tubes were measured at 16, 23, and 37 days, post-treatment. Three treatments consisted of i) irrigating both tubes when soil water potential reached -1 5 kPa (...

Surface water resources, especially rivers, are at risk more than other sources for the reason of many uses. This study aims to examine some quality parameters of Karun river water in the Gotovand spatial range to Ahwaz during the years of 2010-2013.The data investigated in this study were obtained from the annual mean biochemical parameters measurements at nine sampling stations at the Water A...

the effect of different fertilizing systems and drought stress during grain development on grain minerals of barley (hordeum vulgare l.) was studied in field experiments on a clay-loamy soil during 2007 and 2008 growing seasons. the treatments consisted of three irrigation regimes (main plots) of: non-stressed (ns, normal irrigation continued until the end of plant physiological maturity), ...

background: uranium poses both chemical and radiological hazard to the living system. drinking water from river is one of the major sources of uranium intake. dissolution of minerals, washout from rain water, rock-water interaction, agricultural run off, and industrial disposals are some of the sources of uranium in river water system. present study was aimed to determine the uranium in the wat...
