Water stress is a frequent and critical limit to wheat (Triticum aestivum L.) production in North China. It has been shown that photosynthetic active radiation (PAR) is closely related to crop production. An experiment was conducted to investigate the effects of deficit irrigation and winter wheat varieties on the PAR capture ration, PAR utilization and grain yield. Field experiments involved J...

Should I switch from conventional till to no-till wheat production? This is one of the most common questions asked by Oklahoma farmers, but it is also one of the most difficult to answer. There are several considerations when making this decision, and there is certainly no one-size-fits-all program for converting from conventional till to no-till wheat production. A few factors to be considered...

The effect of short exposures to spinosad-treated wheat, Triticum aestivum L., or maize, Zea mays L., was evaluated against adults of four stored-product insect species: lesser grain borer, Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae); rice weevil, Sitophilus oryzae (L.) (Coleoptera: Curculionidae); red flour beetle, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae); and the psoc...

Trametes hirsuta (GenBank Accession Number: AB429065.1), a basidiomycete fungus was used for the production of laccases using different carbon sources namely glucose, sawdust, rice bran and wheat bran. Use of organic medium (agricultural/industrial wastes) is aimed to bring down the cost of media. Among these four carbon sources, the best laccase production was obtained in sawdust followed by w...

Wheat (Triticum aestivum) production in the rainfed area of Pothwar Pakistan is extremely vulnerable to high temperature. The expected increase in temperature due to global warming should result in shorter crop life cycles, and thus lower biomass and grain yield. Two major factors control wheat phenological development: temperature and photoperiod. To evaluate wheat development in response to t...

Sprouting of grains in mature spikes before harvest is a major problem in wheat (Triticum aestivum) production worldwide. We cloned and characterized a gene underlying a wheat quantitative trait locus (QTL) on the short arm of chromosome 3A for preharvest sprouting (PHS) resistance in white wheat using comparative mapping and map-based cloning. This gene, designated TaPHS1, is a wheat homolog o...

A knowledge model with temporal and spatial characteristics for the quantitative design of a cultural pattern in wheat production, using systems analysis and dynamic modeling techniques, was developed for wheat management, as a decision-making tool in digital farming. The fundamental relationships and algorithms of wheat growth indices and management criteria to cultivars, ecological environmen...

Fusarium species infect cereal crops worldwide and cause the important diseases Fusarium head blight and crown rot in wheat. Fusarium pathogens reduce yield and some species also produce trichothecene mycotoxins, such as deoxynivalenol (DON), during infection. These toxins play roles in pathogenesis on wheat and have serious health effects if present in grain consumed by humans or animals. In t...

proper conditions for producing crude beta-galactosidase from waste materials were de-termined. this enzyme is to be used in the production of lactose-hydrolyzed milk. whey permeate was used as a basic medium. twenty seven treatments were developed by 3 vary-ing factors of: yeast extract (1, 2, and 3 %), wheat steep liquor (1, 2, and 3 %), and whey powder (0.5, 1, and 1.5 %). crude enzyme extra...
