To improve the accuracy of winter wheat yield estimation, the Crop Environment Resource Synthesis for Wheat (CERES-Wheat) model with an assimilation strategy was performed by assimilating measured or remotely-sensed leaf area index (LAI) values. The performances of the crop model for two different assimilation methods were compared by employing particle filters (PF) and the proper orthogonal de...

Wheat bran, rye, millet and corn meal supplements used alone or in various combinations with mixed oak sawdust significantly influenced crop cycle time, biological efficiency (BE) and basidiome quality of maitake (Grifola frondosa). The combination of 10% wheat bran, 10% millet and 10% rye and the combination of 10% wheat bran plus 20% rye gave the highest and most consistent yields. The shorte...

Water extractable organic matter (WEOM) is critical for soil fertility because of its role as a readily available C substrate microbial metabolism. In the semi-arid Texas High Plains, dryland cropping systems are common limited precipitation and irrigation water. Little known about long-term effects on WEOM content composition, how these differ from native grassland. The objective this study wa...

Wheat is the main crop and often a strategic crop in many European countries. From a historical perspective, we describe the transfer of "reduced height genes" (Rht genes) from Japanese wheat varieties to wheat varieties in Europe and their influence on the increase of the total wheat production in the last century. Historic pathways of Rht genes were influenced directly or indirectly by wheat ...

Wheat is one of the major cereal crops with annual global production over 600 MT from about 200 M hectares (FAO 2012). The cultivation of wheat started about 10,000 years ago as part of the Neolithic revolution which state a transition from hunting and gathering of food to settle agriculture. Earlier cultivated forms of wheat were diploid (einkorn) and tetraploid (emmer) with known initial orig...

Replacing portions of fallow between sorghum [Sorghum bicolor (L.) Moench] harvest and wheat (Triticum aestivum) planting with cover crops provides opportunity to increase productivity profitability in dryland winter wheat–sorghum–fallow (WSF) cropping systems. The objective this study was identify potential spring replacement management optimize resource use efficiency a WSF system. conducted ...

Crop simulation model has been becoming the core of agricultural production management and resource optimization management. Displaying crop growth process makes user observe the crop growth and development intuitionisticly. On the basis of understanding and grasping the occurrence condition, popularity season, key impact factors for main wheat diseases of stripe rust, leaf rust, stem rust, hea...
