The aim of the present investigation was to determine the allelopathic effect of aqueous extract from either fresh or oven dried leaves and root of unstressed or water stressed maize plants on soybean growth and its effects on rhizosphere soil treated with maize plant extract. The extracts were applied for 10h to soybean [Glycine max (L.) Merr.] as seed soaking treatment prior to sowing. The ap...

Western corn rootworm (Diabrotica virgifera) (WCR) depends on the continuous availability of corn. Broad adoption of annual crop rotation between corn (Zea mays) and nonhost soybean (Glycine max) exploited WCR biology to provide excellent WCR control, but this practice dramatically reduced landscape heterogeneity in East-central Illinois and imposed intense selection pressure. This selection re...

Drought stress is a major constraint to the production and yield stability of soybean [Glycine max (L.) Merr.]. For developing high yielding varieties under drought conditions, the most widely employed criterion has traditionally been direct selection for yield stability over multiple locations. However, this approach is time consuming and labor intensive, because yield is a highly quantitative...

Soybean (Glycine max L.) is an important source of protein for human and animal nutrition, as well as a major source of vegetable oil. The soybean crop requires adequate water all through its growth period to attain its yield potential, and the lack of soil moisture at critical stages of growth profoundly impacts the productivity. In this study, utilizing (1)H NMR-based metabolite analysis comb...

The western corn rootworm (WCR,Diabrotica virgifera virgifera LeConte) is an important pest of corn. Annual crop rotation between corn and soybean disrupts the corn-dependent WCR life cycle and is widely adopted to manage this pest. This strategy selected for rotation-resistant (RR) WCR with reduced ovipositional fidelity to corn. Previous studies revealed that RR-WCR adults exhibit greater tol...

Changes in plant metabolism due to water deficit combined with other stresses, such as high irradiance and temperatures, cause damage the physiology development of crops, which can lead significant yield losses. The aim this study was determine potential potassium phosphite (PP) induce tolerance soybean plants. experiment carried out an acclimatized growth chamber. Soybean plants, upon reaching...

J. Econ. Entomol. 85(4): 1507-1515 (1992) ABSTRACT Resistance in certain genotypes of soybean, Glycine max (L.) Merr., has been shown to adversely affect insect behavior and development in laboratory feeding experiments involving excised leaf material. This study investigated effects of resistance in various developmental stages of intact soybean plants on feeding behavior and physiology of cor...

Calcium-dependent protein kinases (CDPKs) are plant-specific calcium sensors that play important roles in various aspects of plant physiology. Here, we investigated phylogenic relationships, chromosomal locations, gene structures, and tissue-specific, herbivory- and drought-induced expression profiles of soybean (Glycine max) GmCDPKs. Fifty GmCDPK genes were identified, which phylogenetically g...
