Two field experiments were carried out at the village ten, Abu Humus, El-Beheira Governorate, Egypt, during two successive seasons 2016/2017 and 2017/2018, to evaluate effect of three types herbicide irrigation intervals on productivity quality onion cultivar (Giza Red). The designed as split plot in randomized complete block design with replications. Irrigation – (I1) 20 days, (I2) 30 (I3) 40 ...

efficacy of many herbicides to control broad- and narrow-leaf weeds (grass weeds) in tobacco fields of mazandaran and guilan provinces was investigated. the experiment was randomized complete blocks design in four replications and the following treatments: eptam (eradicane 82% ec) at 6 l.ha-1 which incorporated pre-planting (ppi), trifluralin (treflan 48% ec) at 2 l/ha ppi, cycloate (roneet 72....

a field study was conducted to determine the integration of split n fertilization and herbicide application on weed management and wheat (triticum aestivum l.) yield in shiraz, iran, in 2005/2006 and 2006/2007 growing seasons. the experimental design was split plot with four replications. main factors consisted of n timing and splitting, and sub plots included iodosulfuron–methyl–sodium plus me...

The genotoxic effects of the herbicide oxyfluorfen on root meristem cells Heianthus annuus L. (sunflower) were investigated. roots treated with 75, 150, and 300 ppm concentrations for 12 24 h. different genetic endpoints such as mitotic index (MI), chromosome aberrations (CA), micronuclei (MN) analyzed in both control test groups. showed a marked mitodepressive action mitosis. Additionally, MN ...

The response of plants to the peroxidizing herbicide oxyfluorfen was investigated. The action of this p-nitrodiphenyl ether is based on inhibition of plastidic protoporphyrinogen oxidase, which leads to accumulation of protoporphyrin IX in the cytosol yielding reactive oxygen species by light activation. The induction of activities of antioxidative enzymes was followed in Nicotiana tabacum plan...

X 1908+075 is an optically unidentified and highly absorbed X-ray source that appears in early surveys such as Uhuru, OSO-7, Ariel V, HEAO-1, and the EXOSAT Galactic Plane Survey. These surveys measured a source intensity in the range of 2–12 mCrab at 2–10 keV, and the position was localized to ∼ 0.5. We use the Rossi X-ray Timing Explorer (RXTE) All Sky Monitor (ASM) to confirm our expectation...

In this work, the cytotoxic and genotoxic influences of oxyfluorfen herbicide were surveyed by examining mitotic index, stages, chromosomal anomalies, micronucleus percentage, comet assay parameters on somatic cells Allium cepa. The roots treated with 0.2, 0.4, 0.8 1.6 ppm concentrations 12, 24 36 h. application periods. Mitotic index was noticeably diminished in each group when matched their c...
