Labor-saving Cultivation Practice of Tartary Buckwheat in Korea

摘要

This study is conducted to develop labor-saving culture practices for the effective production of Tartary buckwheat. Seeds of KW53 sterilized with Venomil powder were sawn at a rate of 13kg/10a in a farmer's field at Bongpyoung town on April 23, 2005. Compound fertilizer(N-P-K=8:14:12) was spreaded as basal dressing at a rate of 25kg/10a. Seeding rates were 6kg/10a for broadcast seeding by hand and 3.2kg/10a for soil covering direct seeding machine. Three kinds of herbicide treatments such as Lasso only, mixture of Lasso and Gramokson, and successive combination of Lasso and Gramokson and hand picking off as a control were made in order to save labor to control weeds. At the 90th days after sawing, plants were harvested by different methods such as mower, combine, and man-power. In this Tartary buckwheat study, it was found that yield increased upto 40% with soil covering direct seeding machine and save labor upto 96% by using combine.
