In order to evaluate the productivity potential of some bread wheat varieties and promising lines under no-till rainfed condition two different on-farm trials were conducted in cold (Sonqor) and warm (Sarpol-e Zahab) regions of Kermanshah province during 2017-18 cropping season. In the cold condition, 12 winter genotypes and in the warm condition 32 spring genotypes were evaluated for grain ...
Water erosion and runoff can be severe due to poor infiltration through frozen soil in the dryland wheat (Triticum aestivum L.) production region of the inland Pacific Northwest (PNW), USA. For more than 70 years, farmers and researchers have used various methods of subsoiling to reduce runoff and erosion and to improve infiltration and soil moisture storage. The practice and equipment have evo...
Many farmers in the steeply sloped Palouse region of eastern Washington and northern Idaho practice no-till (NT) farming. Soil quality and water intake parameters were assessed in standing wheat (Triticum aestivum L.) stubble along summit, side, and toe-slope positions in a 2-yr study at three paired-farm sites using traditional tillage (TT) vs. NT management. Paired sites had similar south-fac...
A 2-year tillage-based winter wheat (Triticum aestivum L.)-summer fallow (WW-SF) rotation has been practiced by the vast majority of farmers in the low-precipitation (<300 mm annual) rainfed cropping region of east-central Washington and north-central Oregon for 140 years. Until recently, alternative crops (i.e., those other than WW) so far tested have not been as economically viable or stable ...
Nitrogen fertilizer is commonly applied to winter wheat in the High Plains to achieve moderate to high yields. Typically, anhydrous N is applied in the summer or early fall with a tillage operation. Some growers apply liquid N in the spring if winter and spring moisture are high to take advantage of higher yielding condition. Phosphate fertilizer is less frequently used on winter wheat than N f...
Wheat is one of the founder crops of Western agriculture. This study reconstructs agronomic conditions, potential yields, and kernel weight in the beginnings of cultivation of domesticated free-threshing wheat, c. 8000 BC. The carbon and nitrogen stable isotope compositions and the dimensions of fossil grains of naked wheat (Triticum aestivum/durum) were analysed. Samples were collected in Tell...
The effects of nitrogen (N) accumulation and translocation on photosynthesis have been widely reported, while the impacts N accumulation, translocation, simultaneous improvements in grain yield gluten quality dryland wheat still remain unclear. For this reason, relationships between photosynthesis, use efficiency (NUE), related traits yield, quality, 11 representative genotypes 2018–2021 croppi...
