Producing seedlings in forms, with or without pressing the nutritional mixture (the seedlings are replanted with the nutritive substrate, in which they developed) makes this method particularly useful for cultivation technologies in greenhouses and solariums. Seedlings produced in pots or cubs are obtained by directly sowing plants in pots or cubes, in order to replant them in the definitive place along with the soil they grew in, so that the roots are affected as little as possible. Thus, the shock caused by replanting is reduced, the setting occurs more rapidly and plants continue to grow without any stagnation in vegetation, obtaining earlier and larger productions. Potting soil ensures better nutrition conditions, water and nutrient reserves, which ensure that seedlings set even in draught conditions. In the paper experimental researches are presented conducted in the laboratory to determine functional and qualitative work indices of an installation for simultaneously filling pots with nutritive mixtures and sowing. This installation operates in stationary conditions in multiplication greenhouses, having the role of simultaneously filling plastic material pots (6, 8, 10 and 12 cm square and 6-12 cm high) with nutritive material and sowing. The installation can also be used to fill pot sets, made from 2, 3, 4 and 5 cm hexagonal (honeycomb shaped) paper. Functional work indices determined were: linear speed of the conveyor from the filling machine, flow rate of the distribution device from the filling machine, the depression in the distribution head. Qualitative work indices determined were: compaction degree, sowing precision as the number of seeds in pots, lateral seed displacement compared to the centre of the pot, the depth of burying the seeds.
