The possible reason for this effect of tillage systems on seed bank may be attributed to the reduction of seed bank density of field bindweed in conventional tillage due to frequent plowings and resultantly maximum seed germinations in rainy seasons because the repeated tillage operations might have brought the seeds of field bind weed near the soil surface which emerged rapidly due to more soil aeration and availability of sunlight (Cardina et al., 2002).
Economic evaluation of field bindweed (Convolvulus arvensis) control in a winter wheat-fallow rotation.
Because of all abovementioned the identification of allelopathic effects of field bindweed and effect of water soluble chemicals can lead to a better understanding of the weed and reduction of the negative impact on early growth of maize.
The plants of field bindweed were collected during the summer of 2012 at the flowering stage (Hess et al.
The presence and mismanagement of field bindweed population and high concentrations of water soluble chemicals produced can negatively affect germination and early growth of maize.
Ghareib (2010): Methanol Extract Potential of Field Bindweed (Convolvulus arvensis L.) for Wheat Growth Enhancement.
Study of allelopathic effects of aqueous extracts of roots and seeds of goosefoot red-root amaranth and field bindweed on germination and growth of lentil seedlings.
Most of reduction effects were obtained by adding leaf residues from field bindweed leaf and the least by adding the residues of whole plant.
Rate of leaf area per plant of wheat equivalent to 21.45 [cm.sup.2] in control conditions in which decreased significantly with different amounts of residues from field bindweed. This reduction increased by adding the amount of residues to soil so that adding 40g.
and leaf residues treatment yield the maximum grain as 3.31 g, thus adding 40 g residues root, stem, leaf and whole plant of field bindweed to soil decreased 38.79, 35.05, 14.58 and 22.25 % grain yield, respectively.
The results of this study showed that the residues of roots and shoots of field bindweed (C.
"If we could get these three together, this would give us a good start on controlling field bindweed
," Boldt says.
