Increasing plant diversity in the perennial phase of pasture-crop rotations is predicted to positively affect belowground productivity and microbial communities and, turn, augment agroecosystem services including soil health carbon storage. Using two grass one legume forage species grown as monocultures combined four intercropped combinations, we evaluated how identity richness influence produc...

Plant contamination by polycyclic aromatic hydrocarbons (PAHs) is crucial to food safety and human health. Enzyme inhibitors are commonly utilized in agriculture to control plant metabolism of organic components. This study revealed that the enzyme inhibitor ascorbic acid (AA) significantly reduced the activities of peroxidase (POD) and polyphenol oxidase (PPO), thus enhancing the potential ris...

Soil nitrogen (N) is a common limiting factor where soil N-cycling key component of agroecosystems. N transformation processes are largely mediated by microbes, and understanding bacteria involvement in agricultural systems has both agronomic environmental importance. This 2 yr field-scale study examined the abundances spatial distributions total bacterial community (16S rRNA), involved nitrifi...

Performance of eight spring-flowering bulbs, Chionodoxa sp. ‘Blue Giant’ (glory-of-the-snow), Crocus tommasinianus ‘Ruby (crocus), vernus ‘Remembrance’ Narcissus ‘Ice Follies’, N. ‘Tete-a-Tete’, ‘Thalia’ (daffodil), Muscari Magic’ (grape hyacinth), and Scilla sybirica (Siberian squill), was evaluated after planting into cool season tall fescue lawn [Lolium arundinaceum (Schreb.) Darbysh. (syn. ...

Abscisic acid (ABA) is known to play roles in regulating plant tolerance to various abiotic stresses, but whether ABA's effects on heat tolerance are associated with its regulation of heat stress transcription factors (HSFs) and heat shock proteins (HSPs) is not well documented. The objective of this study was to determine whether improved heat tolerance of tall fescue (Festuca arundinacea Schr...

Many states have passed legislation that regulates agricultural P applications based on soil P levels and crop P uptake in an attempt to protect surface waters from nonpoint P inputs. Phytase enzyme and high available phosphorus (HAP) corn supplements to poultry feed are considered potential remedies to this problem because they can reduce total P concentrations in manure. However, less is know...

The formation of aerenchyma in adventitious roots is one the most crucial adaptive traits for waterlogging tolerance plants. Pasture grasses, like other crops, can be affected by waterlogging, and there scope to improve through breeding. In this study, two summer-active cocksfoot (Dactylis glomerata L.) cultivars, Lazuly Porto, tall fescue (Lolium arundinaceum Schreb., syn. Festuca arundinacea ...

Cadmium (Cd) and lead (Pb) are recognized as the most toxic metal ions due to their detrimental effects not only to plants, but also to humans. The objective of this study was to investigate the effects of Cd and Pb treatments on seed germination, plant growth, and physiological response in tall fescue (Festuca arundinacea Schreb.). We employed six treatments: CK (nutrient solution as control),...
