A seed-sowing assembly, especially of rice, consisting of at least two single seeding units arranged in parallel and displaced longitudinally from each other, which allows a narrow separation between furrows, wherein each of said single units comprises a first pivoting support arm connected at one of its ends that supports a load regulator； and a second pivoting support arm connected to another end of the first support arm that supports at least one furrow-generating disc； at least one depth limiting wheel coupled to at least one furrow-generating disc； a seed contact wheel； and a third pivoting support arm connected to one end of the second support arm that supports two furrow-closing wheels. A seed-sowing machine comprising the seed-sowing assembly.
