Effect of Buckwheat (Fagopyrum esculentum)on Soil Aggregate Stability and Suppression of Common Weed Varieties

Abstract

Farmers and agricultural researchers have become increasingly interested in looking for more effective ways to reduce crop yield limitations. For the diversity of their functions, cover crops have been one area of focus. The fast germination, quick growth, and broadleaf structure of buckwheat (Fagopyrum esculentum) allow for its effective use as a cover crop, particularly as a weed suppressant. Past studies have suggested that buckwheat is able to maintain or improve soil structure; further investigation is needed in order to determine the exact effect. In this study, I observed whether seeding method and seeding rate of buckwheat had a beneficial effect of suppressing weeds and building soil structure. Central aim: Determine the seeding rate and method of buckwheat at which both weed suppression and improvement of soil structure can be obtained.
