Intercropping is a sustainable practice to achieve higher production with the aim to limit external inputs. A field experiment was conducted at the research farm of the Faculty of Agriculture, University of Maragheh, Maragheh, Iran, during 2016 growing seasons with ten treatments to evaluate the yield, analyze the competition and insect’s assemblages in sunflower (as main plant)/soybean (as com...

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...

in order to study the weed populations in wheat, under different crop rotations an experiment was carried out at agricultural research station of jolgeh rokh, iran. during growing season this project was done in five years, based on randomized complete bloch design with three replications, on crop rotations included: wheat monoculture for the whole period (wwwww), wheat- wheat- wheat- canola- w...

The dominance of invasive species is often assumed to reflect their competitive superiority over displaced native species. However, invasive species may be abundant because of their greater tolerance to anthropogenic impacts accompanying their introduction. Thus, invasive species can either be the drivers or passengers of change.We distinguish between these two possibilities in California grass...

Aquaponics is an innovative, eco-friendly, and sustainable food production system that combines hydroponic crop with recirculating aquaculture. This study aimed to assess the haematological, biochemical, health status of Nile tilapia common carp in monoculture polyculture systems. A total 800 (Oreochromis niloticus) (Cyprinus carpio) average body weight 1.1± 0.2 g were used. The fish divided in...
