The objective of this paper was to analyse allelopathic effect 3 different aqueous solutions from tree heaven’s (Ailanthus altissima (Mill.) Swingle) root extract and their dilutions on common wheat (Triticum aestivum L.), pigweed (Amaranthus retroflexus L.) red bristlegrass (Setaria pumila L.). Investigated obtained were solution, solution with isolated ailanthone without ailanthone. Each thes...

Field and greenhouse studies were conducted to investigate the compatibility of MSMA in a tank mixture with glyphosate or glufosinate for broadleaf and grass weed control. Glyphosate, glufosinate, and MSMA were evaluated at 0.53, 13, and 23 rates, with 13 rates of 0.84 kg ae/ha, 0.5 kg ai/ha, and 2.2 kg ai/ha, respectively. Glyphosate and glufosinate provided similar levels of control for most ...

Experiments were conducted to evaluate the effect of tillage systems and weed management on weed suppression and potato yield. Striptillage (ST) and conventional-tillage (CT) systems produced equal yields of Irish potato (Solanum tuberosum L.) or sweetpotato [Ipomoea batatas (L.) Lam.] when herbicide treatments were applied. Weeds in the nontreated control reduced yield of Irish potato and prev...

In order to quantifying emergence pattern of rapeseed weeds, this experiment was conducted in 40 plots (40 quadrates at Agricultural Sciences and Natural Resources University of Khuzestan, and 30 fields of Bavi (30 quadrates), Ahvaz, Iran, in 2016-2017 growing seasons was monitored, counted and recorded weekly. Three different emergence pattern of nine weed species were identified, Prickly lett...

Soil temperature influences crop growth and quality under field and greenhouse conditions; however, precise investigation using controlled cultivation systems is largely lacking. We investigated effects of root-zone temperatures on growth and components of hydroponically grown red leaf lettuce (Lactuca sativa L. cv. Red Wave) under a controlled cultivation system at 20 ̊C. Compared with ambient ...

In previous studies we proposed the plant leaf fatty acid composition, and more precisely the ratio C18:3/(C18:0 + C18:1 + C18:2) as a tool to diagnose soil contamination ex situ. These studies led us to normalize this parameter as a biomarker of soil quality using Lactuca sativa growing under controlled conditions as the plant model species. The evaluation of the toxic effects of pollutants is...
