In the worldwide search for new strategies in sustainable weed management, the use of plant species able to produce and release phytotoxic compounds into the environment could be an effective alternative to synthetic herbicides. Eucalyptus globulus Labill. is known to be a source of biologically active compounds responsible for its phytotoxic and allelopathic properties. Our previous results de...

This study attempts to analyze teaching and learning processes of web-based instruction (WBI) as shown in recent literature, and to develop a theoretical framework of WBI using a prominent existing distance education theory called Transactional Distance Theory in order to provide better understanding of the essential pedagogical components of WBI. Recent studies have shown that the key elements...

in order to study the response of wheat (triticum aestivum) cv. chamran and wild barley (hordeum spontaneum) to different herbicides, a pot dose response experiment was conducted in a completely randomized design with three replication at research greenhouse of ferdowsi university of mashhad in 2008. different doses of herbicides including clodinafop propargyl, pinoxaden, sulfosulfuron, and met...
