High Seed Retention at Maturity of Annual Weeds Infesting Crop Fields Highlights the Potential for Harvest Weed Seed Control
Seed production of annual weeds persisting through cropping phases replenishes/establishes viable seed banks from which these weeds will continue to interfere with crop production. Harvest weed seed control (HWSC) systems are now viewed as an effective means of interrupting this process by targeting mature weed seed, preventing seed bank inputs. However, the efficacy of these systems is directl...
متن کاملEffects of Mix Cropping of Alfalfa and Annual Ryegrass on Forage Production
Mix cropping of alfalfa (Medicago sativa) and annual ryegrass (Lolium rigidum) may improve forage production in the rangeland and field conditions, especially in spring after the establishment year. In this study, the effects of different sowing rates of alfalfa and annual ryegrass seeds in the replacement and additive series of mix cropping were evaluated on forage yield in first year after th...
متن کاملControl of Italian Ryegrass (Lolium multiflorum) in Wheat (Triticum aestivum) with Several Postemergence Herbicides
Field experiments were conducted in Virginia in 2000 and 2001 to investigate responses of wheat and diclofop-methyl-sensitive and –resistant Italian ryegrass to POST applications of several experimental and registered herbicides. The experimental herbicide combination AE F130060 03 was as effective as diclofop-methyl and more effective than chlorsulfuron plus metsulfuron, chlorsulfuron plus met...
متن کاملAgizicui:fural Economics School of Agriculture a Model of Wheat Yield Response to Application of Diclof0p-methyl to Control Ryegrass (lolium Rigidum)
A general model of crop yield response to herbicide application is proposed. The model includes three components: the effect of herbicide dosage on weed density, the effect of surviving weed density on crop yield and the effect of herbicide directly on the crop. The model is used to estimate the response of wheat yield to application of diclofop-methyl to control ryegrass .(Lolium rigidum) in A...
متن کاملارزیابی مقاومت به خشکی در دو گونه چمن بومی ایران
In recent decade, establish and maintenance of turf grasses is faced with serious doubts due to reduction of precipitation and water resources. So, identification of drought-resistant native and rangeland species, and introducing them as turf grass not only is effective in reducing water consumption, but also help to preserve the genetic resources of the country. In order to evaluate the usabil...
