Background: In Iran, maize is cultivated in wide areas including northern provinces. It is one of the most important crops for poultry and livestock feeding, which is susceptible to aflatoxins (AFs) contamination. So, pre-harvest maize samples from Mazandaran province, north of Iran were analyzed for AFs contamination. Objective:   Methods: Thirty-five pre-harvest maize samples were analyzed ...

The widespread planting of crops genetically engineered to produce insecticidal toxins derived from the bacterium Bacillus thuringiensis (Bt) places intense selective pressure on pest populations to evolve resistance. Western corn rootworm is a key pest of maize, and in continuous maize fields it is often managed through planting of Bt maize. During 2009 and 2010, fields were identified in Iowa...

Lady beetles (Coleoptera: Coccinellidae) are important polyphagous predators in maize, Zea mays L., fields. Transgenic Cry3Bb1 maize hybrids express a coleopteran-specific insecticidal protein derived from Bacillus thuringiensis (Berliner) subsp. kumamotoensis that is targeted at corn rootworm larvae. This study evaluated impacts of Cry3Bb1 protein-expressing maize, tefluthrin-treated maize, an...

In maize (Zea mays L., 2n = 2x = 20), map-based cloning and genome organization studies are often complicated because of the complexity of the genome. Maize chromosome addition lines of hexaploid cultivated oat (Avena sativa L., 2n = 6x = 42), where maize chromosomes can be individually manipulated, represent unique materials for maize genome analysis. Maize chromosome addition lines are partic...

Eight maize varieties viz. four composites (Mohor, Barnali, Khoibhutta, and BARI Maize-6) and four hybrids (BARI Hybrid Maize-1, BARI Hybrid Maize3, BARI Hybrid Maize Top 1 & Pacific 984), were tested for their response to zinc fertilization (0 and 3 kg Zn/ha) at the Regional Agricultural Research Station (RARS), Jessore (AEZ-11, High Ganges River Floodplain) during 20022005. The varieties were...

intercropping systems are one of the best approaches in development of sustainable agriculture. based on this purpose, the present study was conducted to evaluate effect of strip intercropping on maize and bean growth analysis and their yield during 2009. the experiment was set up in a completely randomized block with 3 replications and 6 treatments based on replacement design. the treatments w...

Background and Aims Maize bushy stunt phytoplasma (MBSP) is a bacterial pathogen of maize ( Zea mays L.) across Latin America. MBSP belongs to the 16SrI-B sub-group within the genus ' Candidatus Phytoplasma'. MBSP and its insect vector Dalbulus maidis (Hemiptera: Cicadellidae) are restricted to maize; both are thought to have coevolved with maize during its domestication from a teosinte-like an...

A total of 280 unsexed broiler chicks, 21 days-old and weighing 580 g on average were randomly distributed into 28 experimental units of 10 birds each. Seven experimental diets containing respectively 0% (T0 control), 20% raw cowpeas (T1), 20% raw cowpeas + 0.2% of Canarium charcoal (T2), 20% raw cowpeas + 0.2% maize cob charcoal (T3), 20% cooked cowpeas (T4), 20% cooked cowpeas + 0.2% Canarium...

Bacterial diversity and community structure of two maize varieties (white and yellow) during fermentation/steeping for ogi production, and the influence of spontaneous fermentation on mycotoxin reduction in the gruel were studied. A total of 142 bacterial isolates obtained at 24-96 h intervals were preliminarily identified by conventional microbiological methods while 60 selected isolates were ...

The cytogenetic interactions in maize x Tripsacum hybrid derivatives can be remarkably complex. The number of viable, somewhat female fertile chromosome combinations is astonishing. Fifty-four different combinations are listed in this paper, and others are certainly possible. In successive backcrosses to maize, chromosome numbers scale both up and down with ease, sometimes stabilizing for a few...
