A two year trial (2005-2066) was conducted in order to study the influence of plant density and seed inoculation on 1,000 grain mass and seed yield. As a material of soybean variety ZPS 015 was used. Variety is grown in optimal (recommended) plant density (500,000 plants/ha), than in plant density less for 100,000 plants/ha than optimal (400,000 plants/ha). The second investigation factor included variants with and no inoculations. Small field trials wee conducted on carbonate chrnozem soil type using a split plot design in three replication. Achieved results show that spoybean productivity depended upon plant density and seed inoculation. The highest 1,000 grain mass is registered in reduced plant density, what is expected. It was equally decreased with increasing plant density. The highest seed yield is registered on optimal (recommended) density. On average for examined plant densities, seed inoculation increased 1,000 grain mass for 4.2% and seed yield for 10.2%.
