To deliver food security for the 9 billon population in 2050, a 70% increase in world food supply will be required. Projected climatic and environmental changes emphasize the need for breeding strategies that delivers both a substantial increase in yield potential and resilience to extreme weather events such as heat waves, late frost, and drought. Heat stress around sensitive stages of wheat d...

in order to evaluate the effects of yield and yield components and weed diversity and density in row intercropping for wheat and canola, a field experiment was conducted based on a complete randomized block design with three replications at the agricultural research station of ferdowsi university of mashhad, iran during two growing seasons of 2008-2009 and 2009-2010. treatments included four pa...

cultivars, net return is maximized when grazing is terminated at first hollow stem—the stage at which hollow Although grazing of winter wheat (Triticum aestivum L.) is a stem can first be identified above the crown (Redmon common practice in the southern Great Plains, little is known about the efficacy of wheat as a dual-purpose crop in the Nebraska Panhanet al., 1996). However, beyond an optim...

High temperature (HT, heat) stress is detrimental to wheat (Triticum aestivum L.) production. Wild relatives of bread wheat may offer sources of HT stress tolerance genes because they grow in stressed habitats. Wheat chromosome translocation lines, produced by introgressing small segments of chromosome from wild relatives to bread wheat, were evaluated for tolerance to HT stress during the grai...

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...

Improving the efficiency of resource utilization has received increasing research attention in recent years. In this study, we explored the potential physiological mechanisms underlying improved grain yield and water-use efficiency of winter wheat (Triticum aestivum L.) following organic fertilizer application. Two wheat cultivars, ChangHan58 (CH58) and XiNong9871 (XN9871), were grown under the...

to study the effects of urea foliar spray at different plant growth stages on grain yield and protein percentage of two dryland wheat varieties of sardari and azar 2, an experiment was conducted in east mangor agricultural station of mahabad in 2007– 2008. the experiment design was split plot based on randomized complete block design with three replications. treatments were 50 gr×10 m-2 n as ur...

Wheat (Triticum aestivum L.) is one of the most important agricultural crops in China. In addition to the yield, the grain quality of wheat is central to the well-being of humans. Because of its high grain protein content (GPC), wheat is extensively applied in many foods and industrial uses. Currently, increasing grain quality is becoming a widely discussed topic in crop sciences. Wheat quality...

The objective of this experiment was to study of water relations and chlorophyll in different wheat genotypes and their correlations with grain and biological yields. 21 genotypes of bread wheat were compared in a field experiment as randomized complete blocks design with four replications. The results showed that relative water deficit, relative water loss, excised leaf water retention, cell m...

This study setout to investigate the effect of wheat residue, tillage, and nitrogen fertilizer management on some agronomic traits of soybean as a split split plot based on randomized complete block design with three replications. The main plots included wheat residue management: collecting and leaving residue and sub plot included tillage (without tillage and conventional tillage), and the sub...
