The chemical interaction between plants, which is referred to as allelopathy, may result in the inhibition of plant growth and development. The objective of this research was to determine the impact of kenaf (Hibiscus cannabinus L.) plant extracts on the seed germination of five plant species. Four concentrations (0, 16.7, 33.3 and 66.7 g/L) of kenaf leaf, bark, and core extracts were applied t...

Heavy metal contaminated soil raises major global environmental and agricultural concern. Recently soil pollution through lead (Pb) and chromium (Cr) becoming serious problem and remediation or utilization of those contaminated soil with potential crops is of the outmost importance. The objectives of present study were to examine the effects of Pb and Cr on three different kenaf and mesta varie...

shortage of irrigation water is a crucial problem especially in arid and semiarid regions; therefore, application of wastewater in agriculture in such regions seems to be an indispensable solution. a field experiment was conducted in non-agricultural soil to investigate the effect of treated municipal wastewater (tmw) on the yield and fiber quality of cotton (gossypium hirsutum l.) crop. the tr...

Currently, biofibers are used as a reinforcement in polymer composites for structural elements and construction materials instead of the synthetic fibers which cause environmental problems expensive. One chemicals with pH close to neutral that can be potentially modified fiber material is sodium chloride (NaCl). Therefore, this study aims investigate characteristics composite board made from Na...

This study was devoted to the development of pulp Luffa Cclindrica and its characterization paper (annual plant fiber of the family Cucurbitaceae). Baking at soda helps to achieve a high level of delignification (Kappa ≤ 10) and high yield (≈ 67%).The beatability stack Valley is comparable to refined wood fibers, the fibers develop a normally time with good hydrophilic pro...

Abstract In this research, the hybrid natural fiber composite specimens were fabricated with a 64 wt% epoxy resin matrix, 20 coir fiber, and 16 of various fibers by hand-layup method. The influences (Coir, Jute, Flax, Cotton, Human Hair, Sisal, Kenaf, Calotropis) on mechanical characteristics (tensile, flexural, impact strengths) drilling properties (delamination factor ovality) Coir-fiber base...

The objective of this study was to determine the effect of Verticillium dahliae Kleb. on cotton yield and fiber technological properties, relationships among to disease and seed cotton yield, fiber yield and fiber technological properties and also determine susceptible and tolerant cotton varieties. The study was conducted in the Southeastern Anatolia Agricultural Research Institute’s exper...

Abstract This study investigated the rheological and mechanical properties of cement composites with kenaf jute fibers for use in shotcrete. The length volume fractions fiber were varied; analyzed terms air content, compression flexural tests conducted, degree dispersion was assessed using fluorescence microscopy. rougher surfaces led to a higher yield stress viscosity composite compared fibers...
