Herbicide-resistant weeds are challenging for producers to control in crop fields. This study explores the potential of cover crops reduce weed pressure and improve soil health. Cover that had good canopy development, including grasses such as ryegrass wheat, best control. Soybean yields were similar all crops, though there was a trend towards lower brassica Graza radish forage collards. Soybea...

in order to investigate the effect of different cover crops on density and diversity of weeds, the researcher carried out an experiment in randomized complete block design with seven treatments and three replications for two years (2009-2010) in iran citrus research institute. treatments included planting four cover crops of legumes such as clover (trifolium alexandrinum l.), green bean (phaseo...

A field experiment was conducted to observe the influence of a cover crop (winter wheat, Triticum aestivum L.), and a perennial weed (dandelion, Taraxacum officinale Weber ex Wigg.), on vesicular-arbuscular mycorrhiza (VAM) inoculum potential, soil aggregation, and maize yield after one season. Mycorrhizal colonization of maize roots was higher following the autumn planting of either winter whe...

Sunflower has historically been an important crop in Central Queensland. In recent years the sunflower area in Central Queensland has been reduced due to low and variable prices and increased competition from alternate summer crops. Issues of tall persistent stubble that provides little ground cover and a lack of in-crop weed control options have also contributed to declining popularity of sunf...

In modern agriculture, with more emphasis on high input systems, weed problems are likely to increase and become more complex. With heightened awareness of adverse effects of herbicide residues on human health and environment and the evolution of herbicide-resistant weed biotypes, a significant focus within weed science has now shifted to the development of eco-friendly technologies with reduce...

Weed emergence timing: a new tool for managing weeds in crop fi elds The success of integrated weed management relies on matching control strategies to the specifi c weed problem in a fi eld. Managers must know not only which weed species (and how many) are present in a fi eld; they also must understand the distribution and development stages of these weeds throughout the fi eld. Weed control r...
