The present study deals with the general remarks on the establishment of the direct seed-drilling which may recover wasted pastures in the highland area of Kyushu. The pasture management from the viewpoint of its maintenance and utilization is indispensable to the sustainable production of livestock from pastures. In pastures in the highland area of Kyushu which belongs to the Asian monsoon zone, the persistence of temperate pastures is limited to short years on account of unfavorable conditions such as high temperature and large rainfall in summer and the difficulty in pasture management. The author investigated the vegetation changes that took place in the pasture management related to weather, grazing and fertilization factors. This resulted, however, in wasted pastures owing to overgrazing and fertilizing in summer, where bare grounds appeared and were occupied by various weeds and there was a reduction of main valuable grass species. Orchardgrass (Dactylis glomerata L.) is considered a main grass in the highland area of Kyushu. Then, to recover vegetation simply in wasted pastures, I made attempts at overseeding and weed control which were considered of importance to the pasture management. Moreover, as the overseeding was not easy, some basic experiments were conducted to investigate the effects of various factors on the establishment of seed drilled into pasture sods
