Maize is one of the most productive crops whose seeds are used in poultry sector as main ingredients their diet. It also important forage for ruminants silage. The aim this research was to assess effect defoliation and detopping on dual-purpose maize production field (Kermanshah, Iran, Mediterranean climate conditions) laboratory experiments. study included a control (intact plant), removal lea...

CO477, CO478, CO479, and CO480 are mid- to late-season (75 – 81 days flowering, CHU=1720–1855) corn (Zea mays L.) inbred lines with high stalk sugar levels. The level of in the stalks very especially when grown as lines. On average, inbreds yield three times more than their testcrosses. These first be developed released for biofuel production, from breeding program Agriculture Agri-Food Canada....

Key impediments to increased corn yield and quality in the southeastern US coastal plain region are damage by ear-feeding insects and aflatoxin contamination caused by infection of Aspergillus flavus. Key ear-feeding insects are corn earworm, Helicoverpa zea, fall armyworm, Spodoptera frugiperda, maize weevil, Sitophilus zeamais, and brown stink bug, Euschistus servus. In 2006 and 2007, aflatox...

Average maize yields have increased steadily over the years in the USA and yet the variations in harvestable yield have also markedly increased. Much of the increase in yield variability can be attributed to (1) varying environmental stress conditions; (2) improved nitrogen inputs and better weed control; and (3) continuing sensitivity of different maize lines to the variation in input supply, ...

The effect of plant growth-promoting rhizobacteria (PGPR) on seed germination, seedling growth and yield of field grown maize were evaluated in three experiments. In these experiments six bacterial strains include P.putida strain R-168, P.fluorescens strain R-93, P.fluorescens DSM 50090, P.putida DSM291, A.lipoferum DSM 1691, A.brasilense DSM 1690 were used. Results of first study showed seed I...

The main aim of this research was to study the effect two sowing times (early and late) on Fusarium fumonisin contamination some yield component traits maize hybrids from FAO maturity groups 500 (ZP 560) 600 666) within a two-year growing season (2016–2017). F. verticillioides subglutinans have been identified as ear rot (FER) pathogens potential producers B-type fumonisins (FBs), with predomin...

Shoot apical meristems produce organs in a highly stereotypic pattern that involves auxin. Auxin is supposed to be actively transported from cell to cell by influx (AUXIN/LIKE AUXIN proteins) and efflux (PIN-FORMED proteins) membrane carriers. Current hypotheses propose that, at the meristem surface, PIN proteins create patterns of auxin gradients that, in turn, create patterns of gene expressi...

Fusarium verticillioides (Sacc.) Nirenberg (teleomorph Gibberella moniliformis Wineland) is one of the key pathogens of maize stalk rot disease. However, a clear understanding of stalk rot pathogenesis is still lacking. Previously, we identified the F. verticillioides FSR1 gene, which plays a key role in fungal virulence and sexual mating. The predicted Fsr1 protein contains multiple protein-bi...

Reduced insecticide use in cotton, Gossypium hirsutum L., as a consequence of the Boll Weevil Eradication Program and the broad adoption of Bt cotton, have helped make the tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), a consistent pest of cotton each year in the mid-south. Maize, Zea mays L., has been implicated as having a role in the season-long dynamics of tarnished plant bug...

Smart, M. G., Shotwell, O. L., and Caldwell, R. W. 1990. Pathogenesis in aspergillus ear rot of maize: Aflatoxin B1 levels in grains around woundinoculation sites. Phytopathology 80: 1283-1286. Aflatoxin contamination of preharvest maize intermittently presents serious problems in grain storage and in animal health. To determine whether this mycotoxin can be translocated through the ear in the ...
