Effects of Partial Tillage Seeding of Hairy vetch on Green Manure Biomass and Rice Yield in Rice-based Cropping System
Year: 2013
Type: article
Abstract: To investigate the effect of partial tillage seeding of hairy vetch on green manure biomass and rice yield, on-farm experiment was conducted at eco-friendly hairy vetch cultivation area located in Yesan-gun, Chungcheongnam-do. Seeding methods of hairy vetch consisted of partial tillage seeding (PTS) and broadcasting before rice harvesting (BBRH). Hairy vetch was incorporated into soil on May 18 and rice seedling was transplanted on May 26. The growths of hairy vetch before overwintering were investigated on November 11. Plant height of BBRH plot was longer than that of PTS plot, but somewhat larger number of seedling stand was found in PTS. Biomass and N production of hairy vetch were investigated on May 18. Results of the investigation showed no difference between two seeding methods. Although the seeding time was 21 days late in PTS, the biomass of hairy vetch and rice yield were equivalent to those of BBRH seeding, so we conclude that PTS could improve overwintering survival of hairy vetch in rice cropping system.
