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 ...

Recent studies have shown that estimates of leaf chlorophyll content (Chl), defined as the combined mass of chlorophyll a and chlorophyll b per unit leaf area, can be useful for constraining estimates of canopy light use efficiency (LUE). Canopy LUE describes the amount of carbon assimilated by a vegetative canopy for a given amount of absorbed photosynthetically active radiation (APAR) and is ...

Large numbers of a cockroach that resembled the German cockroach, Blattella germanica (L.), were observed duringwinter 2005Ð2006 in home turf settings inWeslaco, TX, 11 km from theU.S. borderwith northeasternMexico. In June and July 2006, this cockroachwas observed at night on the foliage of soybean,Glycine max (L.)Merr., in numbers often exceeding 50 per m row. Because of its similarity to B. ...

The photosynthetic metabolism is a key point to improve soybean yield. In this work, we demonstrated that radiation use by plants can be improved, aiming the grain yield in lower canopy. objective of study was observe whether increase solar input canopy improves their performance. Three experiments were carried out during 2017/2018 season. For each experiment, treatments consisted opening one o...

Soybean [Glycine max (L.) Merr.] yield has increased over time through the introduction of new varieties and improved agronomic practices. However, seed protein concentration decreased. We conducted field studies in 2018 2019 to investigate effects fungicide, insecticide, foliar fertilizer application on grain quality two soybean maturity groups (MG). In-season treatments targeted nutrient avai...
