Effect of Weed Management Methods on Weed Occurrence and Tea Plant Growth in New Tea Plantation

To develop an effective method for weed control in a newly established tea plantation, various methods of weed management such as soil mulching and growth of cover crops were evaluated in 3 to 4 year-old Hushun cultivar for 3 years in Jeju. The occurrence and occupancy of weeds differed depending on the weed management method applied, with White clover and Red clover suppressing weeds most effectively. Regarding the growth characteristics of covering crops, Italian ryegrass was taller than tea tree, Red clover and Crimson clover were similar, and White clover grew well for the first two years after seeding but was still shorter than tea tree. Biomass production from the control (noninterfered grown weeds) was the highest, followed by Italian ryegrass and Crimson clover. Effect of different weed management methods on the growth of tea tree was negligible. There was no significant difference between the treatment methods on soil. These results indicate that White clover was the most appropriate weed management method for increased tea tree growth, soil properties and weed suppression.
