carbon dioxide is the most important resource for crop growth. in order to investigate the effect of elevated co2 concentration on morphological and physiological characteristics of sesame (sesamum indicum l.) and amaranthus (amaranthus retroflexus l.) an experiment was conducted in greenhouse conditions. the experiment was factorial based on randomized complete block design with six treatments...

Light availability has a profound effect on plant growth and development. One of the ways to study the effects of light intensity on plant growth and development without the confounding problem of photosynthate availability is sucrose injection/supplementation. A greenhouse experiment was conducted to evaluate the effects of light levels (0% and 75% shade) and sucrose injection (distilled water...

Wood vinegar, a by-product of wood pyrolysis, is mostly discarded. vinegar has phytotoxic effect and could be potentially used as naturally derived herbicide for weed control. The objective this research was to evaluate the efficacy from pyrolysis apple (Malus × domestica Borkh.) tree branch wastes control weeds. concentrations required inhibit 50% motherwort (Leonurus cardiaca L.), redroot pig...

The current study aimed to investigate the chemical composition and the synergistic potential of two essential oils (EOs), as obtained from Salvia officinalis L. (SEO), and Thymus vulgaris L. (TEO). The antifungal potential was tested in vitro against Fusarium graminearum (Fg 06_17), the herbicidal effect was studied using weed seeds of Amaranthus retroflexus (ARET), Chenopodium album (CALB), E...

Amaranthus retroflexus L. and Chenopodium album are noxious weeds that have a cosmopolitan distribution. These species successfully invade adapted to wide variety of diverse climates. In this paper, we evaluated the morphology biochemistry 16 populations A. 17 C. Seeds from collected Spain, France, Iran were grown together at experimental field agriculture research University Mohaghegh Ardabili...

Plant defensive metabolite Alkaloid were screened for analyzing their antimicrobial property. The present study quantified the alkaloids present in selected members of tribe Amarantheae. Maximum percentage of alkaloids are shown by Amaranthus tricolor L., Aamaranthus viridis L. and Amaranthus caudatus L. (88.8%) and the least were shown by Amaranthus spinosus L. and Amaranthus dubius Mart. (5.8...

The spatial variation in plant species associated with intercropping is intended to reduce resource competition between species and increase yield potential. A field experiment was carried out on corn (Zea mays L.) and soybean (Glycine max L.) intercropping in a replacement series experiment with weed contamination consist of: weed free, infestation of redroot pigweed, infestation of jimsonweed...
