ABSTRACT:
Seeds of a second crop (e.g. soybeans) are sown in a standing grain crop (e.g. wheat). When the grain crop is ripe it is harvested by cutting with a combine at a level slightly above the top of the partially grown second crop. Seeding of the second crop is performed using a self-driven, preferably three-wheel vehicle carrying a grain drill box having flexible tubes which fit between the rows of grain and each of which discharges the seed into a gap between two downward-inward slanted discs which first cut a slit in the ground, then deposit the seed and finally cover the slit. The discs are supported and their depth controlled in such manner as to cause minimum interference with the grain.
