Effective weed control prior to seeding is essential for proper turfgrass establishment since competition from weeds can cause sward fail. Herbicides with multiple active ingredients different chemical families could increase efficacy, but hinder the of newly seeded turf. Research trials were initiated in fall 2020 Olathe and Manhattan, KS, determine if tall fescue (Schedonorus arundinaceus) be...

Abstract The effects of single species cover crops on corn ( Zea mays L.) N requirement and grain yield are well studied throughout the U.S. Midwest. However, comparing crop mixes that include different compositions grass broadleaf is limited. Fourteen response experiments were conducted in South Dakota from 2018 to 2021. Fall planted after small harvest mixtures dominantly grasses, broadleaves...

Transketolase from the leaves of Nicotiana tabacum var. John William's Broadleaf is inhibited by exposure to low intensity blue light in the presence of low concentrations of FMN, which functions as a sensitizer. The degree of photoinactivation is reduced in the presence of quenchers of triplet FMN. Photoinactivation does not occur in the absence of oxygen and is also lessened in the presence o...

Extreme weather events often cause the input of fresh plant tissues into soils in forests. However, interspecific patterns tree tissue-leached dissolved organic matter (DOM) characteristics are poorly understood. In this study, we collected leaves and twigs two broadleaf trees (Liquidambar formosana Schima superba) coniferous (Pinus massoniana Pinus elliottii) subtropical plantations China, mea...

Food habits of the tuatara (Sphenodon punctatus) on Stephens Island, in north-western Cook Strait, were studied by field observations and faecal analysis. The tuatara is a selective predator, feeding on a wide range of small animals, mainly large insects. Its diet shows seasonal changes and habitat differences, related to local conditions: the coastal broadleaf forest habitat, which predominate...
