Soybean Rust Epidemics as Affected by Weather Conditions in Brazil

Apparent photosynthesis of soybean plants as affected by changes in leaf water potential under field conditions

Fighting Asian Soybean Rust

Phakopsora pachyrhizi is a biotrophic fungus provoking SBR disease. SBR poses a major threat to global soybean production. Though several R genes provided soybean immunity to certain P. pachyrhizi races, the pathogen swiftly overcame this resistance. Therefore, fungicides are the only current means to control SBR. However, insensitivity to fungicides is soaring in P. pachyrhizi and, therefore, ...

Variations in germination and grain quality within a rust resistant common wheat germplasm as affected by parental CO2 conditions

Parental conditions, such as temperature, soil moisture, nutrient availability, light and competition during plant growth and seed maturation, influence seed quality and germinability. Elevated CO2 concentration can be also treated as a parental condition and should be considered when evaluating crop productivity under future climate conditions. Available information on the effect of parental C...

Development of Heterodera glycines pathotypes as affected by soybean cultivars.

The reproductive abilities of four races of Heterodera glycines were compared on soybean cultivars by using single cyst or mass inoculations. Progeny transfers were used to determine changes in reproduction of H. glycines. Reproduction of all races (1, 2, 3, 4) was best on 'Lee' and poorest on P1 88788. The size of females produced and numbers of eggs/female of the different races varied with t...

Soybean Productivity as Affected by Raised Seedbeds Under Dry Environments

Aims / Method: The objectives of this research were to evaluate soybean [Glycine max (L.) Merr.] response to early season iron deficiency chlorosis (IDC), agronomic characteristics, and productivity when grown on raised seedbeds compared with flat seedbeds. Soybean grain yield on raised seedbeds, averaged across six drier environments in 2012, was similar to flat seedbeds. Although grain yield ...
