The tillage-based winter wheat (Triticum aestivum L.)-summer fallow (WW-SF) cropping system has dominated dryland farming in the Pacific Northwest USA for 125 years. We conducted a large-scale multidisciplinary 8-year study of annual (i.e., no summer fallow) no-till cropping systems as an alternative to WW-SF. Soft white and hard white classes of winter and spring wheat, spring barley (Hordeum ...

most part of durum wheat is produced in semitropical dryland regions in iran. heat and drought stresses are the main constraints in these regions. so, identification of durum wheat cultivars with high yield and tolerant to these stresses is the main breeding strategy in dryland agricultural research institute. the genotype capeiti was evaluated at gachsaran agricultural research station from 19...

aftab cultivar originated from national cereal breeding programs .the new cultivar  was evaluated in international high rainfall wheat yield trial nursery at gachsaran and gonbad agricultural research stations (2008-2009). due to optimum grain yield and other agronomic traits, the new cultivar was tested in advanced yield trials in gachsaran, ilam, khoram abad and gonbad research stations (2009...

Sorghum [Sorghum bicolor (L.) Moench] grain yield is severely affected by abiotic and biotic stresses during post-flowering stages, which has been aggravated by climate change. New parental lines having genes for various biotic and abiotic stress tolerances have the potential to mitigate this negative effect. Field studies were conducted under irrigated and dryland conditions with 128 exotic ge...

in order to evaluate the effects of convention and conservation (no-tillage and reduced tillage) tillage methods on wheat and chickpea yield and yield components and soil physical properties under rainfed conditions in kermanshah (n: 34°19', e: 47°17'), some experiments were performed in sararood dryland agricultural research station during three cropping seasons (2011-2014). in the f...

Dryland alluvial rivers vary considerably in character. In terms of processes, high energy, sediment-laden flash floods in upland rivers contrast dramatically with the low sediment loads and languid flows of their lowland counterparts while from a form perspective, the unstable wide, shallow and sandy braid plains of piedmont rivers are quite different from the relatively stable, narrow, deep a...
