Wheat (Triticum aestivum L.) variety mixtures represent a relatively unexplored avenue for maintaining yield and improving flour quality. A field experiment was conducted to examine the responses of three spring wheat varieties in pure variety and in variety mixtures under continuous cropping in Northeast China. Three modern spring wheat varieties, along with a three-variety mixture and a t...

Remote sensing-derived wheat crop yield-climate models were developed to highlight the impact of temperature variation during thermo-sensitive periods (anthesis and grain-filling; TSP) of wheat crop development. Specific questions addressed are: can the impact of temperature variation occurring during the TSP on wheat crop yield be detected using remote sensing data and what is the impact? Do c...

in recognition of the value and limitations of available water resources in agriculture and the occurrence of periodic drought in iran, water conservation and optimal usage of available water is essential. the main objective of this study was to optimize field water management and cropping patterns using deficit irrigation. the effect of reducing water consumption on different growth stages usi...

The effect of cropping system on the distribution of organic carbon (OC) and nitrogen (N) in soil aggregates has not been well addressed, which is important for understanding the sequestration of OC and N in agricultural soils. We analyzed the distribution of OC and N associated with soil aggregates in three unfertilized cropping systems in a 27-year field experiment: continuously cropped alfal...

Diseases can greatly lower wheat yield and grain quality. Leaf rust, Stagnospora (Septoria) glume blotch, Septoria leaf blotch, and powdery mildew have historically been the most damaging diseases on wheat in Alabama. Stripe rust has recently emerged in the Deep South as a very destructive disease of wheat. Field cropping history, cultivar selection, and weather patterns all have a tremendous i...

oroum is a new bread wheat cultivar originated from the cross between cultivar alvand and an exotic wheat line (ns732/her) at oroumieh agricultural research station in 1995-96 cropping season. the f1 plants were grown in oroumieh in 1996-97 cropping season, however f2-f5 population and regional preliminary yield nursery were grown and evaluated at miandoab agricultural research station during 1...

Conducting research on monitoring contaminated fields by heavy metals is necessary in order to achieve sustainable agriculture, increase product quality and keep public health. This study was carried out using split plot experiment based on randomized complete blocks design with three replications during 2014-2015 in Shavor Agricultural Research Center in order to evaluate the effect of croppin...

Two novel antifungal compounds were isolated from a culture broth of Sterile Dark, an unidentified fungus isolated from the rhizosphere of wheat grown in a continuous cropping field. These compounds were elucidated to be phthalide-based compounds by spectroscopic analyses.

Continuous cropping of rice (Oryza sativa L.) and wheat (Triticum aestivum L.) deplete soil fertility and crop productivity. One strategy to increase crop productivity under rice-wheat system is balanced application of crop nutrients. Field experiment was conducted to assess the impact of phosphorus (0, 40, 80, 120 kg P ha(-1)) and zinc (0, 5, 10, 15 kg Zn ha(-1)) on the productivity of rice ge...

Fusarium head blight is one of the most serious cereal diseases of the world. Epidemics of Fusarium head blight can lead to a decline in grain quality and yield. In addition, grains often become contaminated with mycotoxins, which are harmful to humans and animals. In a field survey of winter wheat in Switzerland, Fusarium graminearum proved to be the most prevalent species responsible for head...
