Summary:
Effective nonchemical weed management approaches can assist with weed management problems for which there are no registered herbicides, reduce the use of herbicides in conventional production systems, provide increased options for sustainable systems, and result in more profitable, less labor intensive organic production systems. A multistate project, NE1026: Weed Management Strategies for Sustainable Cropping Systems was recently established and Florida is participating with a focus on cultural weed control utilizing cover crops. Buckwheat has the potential to suppress weeds by competing for resources, by limiting weed seed germination and propagule sprouting through soil microclimate modification, and by allelopathy. An experiment is proposed for spring and fall 2007 to determine the optimal environmental conditions and range of effective planting dates for production of buckwheat, and its effects on weed emergence and growth. T he work will result in preliminary data on optimal planting dates that will be used in developing a proposal to allow completion of the research and development recommendations on optimal planting dates. An additional objective of assessing the impact of different incorporation practices on buckwheat decomposition, regrowth, and weed suppression will be added. This work will facilitate the effective use of buckwheat in suppressing specific problematic weeds in Florida and the southeastern US and contribute to the aggregate data being generated on effective planting windows for buckwheat in other regions of the U.S. Increased use of cover crops for weed management in sustainable agricultural systems, and a decrease in tillage, cultivation and hand weeding in organic systems can be expected, in conjunction with improved weed control and crop yield.
Objectives: To determine the optimal environmental conditions and range of effective planting dates for production of buckwheat as a cover crop and its effect on weed emergence and growth. |
