The current practice used to evaluate broadleaf weed cover in turfgrass is visual assessment, which time consuming and often leads inconsistencies among evaluators. In this study, we investigated the effectiveness of constructing Random Forest models (RF), either pixel-, object-based (OBIA) or a combination both detect quantify cover. High resolution multispectral images were captured 136 plots...
The total concentration of zinc, iron, nitrogen and phosphorus, as well as their water and acetic acid extractable forms – nitrate nitrogen, ammonium nitrogen and phosphate phosphorus – were determined in st. John’s wort herb (Hypericum perforatum l.) yarrow herb (Achillea millefolium l.), nettle leaves (Urtica dioica l.) and birch leaves (Betula pendula roth.), collected from four natural loca...
Plants need essential nutrients for their growth and development. Iron and boron are micronutrients that are needed by plants in very small concentrations. This study was conducted as a pot experiment to investigate the effect of iron and boron on Achillea millefolium in a factorial randomized complete design with three replications. Iron at three levels (0, 5 and 20 μM) and boron at three leve...
Two new aphid species of the nominotypical subgenus genus Macrosiphoniella (Aphidinae) are described from Kazakhstan. Both inhabits yarrow (Achillea millefolium L.). kazakhstanica sp. n. most similar to M. silvestrii Roberti, 1954 but differs latter in number secondary rhinaria apterous and alate viviparous females (5–10 24–26 vs 14–25 48–68), proportion processus terminalis base VI antennal se...
Background and Aim: There are several reports regarding anti-inflammatory and tissue repair properties of the plant Achillea, but neuroprotective role of ethanolic extract of Achillea millefolium has not been studied after peripheral nerve injury. Therefore, the purpose of the present study was to assess neuroprotective effects .of Achillea millefolium ethanolic extract on the spinal cord alpha...
