Title: Weed Occurrence and Control in Simultaneous Wheat Sowing Culture with Rice Harvest under No-tilled Paddy Field
Abstract: To establish weed control method in no-tilled and rice straw-covered wheat sown coincidentally with rice harvest using combine-attached drill seeder, several herbicides and their combination were tested for 2 years. Similar number of panicle to hand-weeding plot was secured at sprayed plot with Buta EC + Glyphosate SL mixture just after seeding. Water-foxtail(Alopeculus aequalis) and broadleaf weeds were controlled effectively by Buta EC + Glyphosate SL mixture, showing the control efficacy of 92 percent. In the 1st cropping year, weed species occurred was simple and water-foxtail predominated nearly half. However, weed species was diversified and water-foxtail predominated 83.5 percent in the 2nd cropping year. Wheat yield of Buta EC + Glyphosate SL plot showed no difference with hand-weeding plot. Dry weight of water-foxtail showed closer linear relationship with wheat yield reduction than that of broadleaf weed.
