This paper surveys sowing norms (row spacing and seed rate) in both our country and the world, as well as the optimal seed rates in grass seed production. It gives a short overview of row spacings and seed rates applied in our and some other countries. Earlier, grass cultivated for the purpose of seed production was grown on small vegetation area. According to some researches, high seed yields can be achieved by cultivating grass on large vegetation area.

The results of the two-year comparative research of qualitative and quantitative traits of marigold seed of different genotypes in regard to the standard cultivar were analyzed. The highest yield of seed in both study years was registered in genotype "King orange", and the lowest in genotype "R". Concerning the quality of seed, that is, germination energy and total germination, the best results were established for genotype "King orange" and the poorest for genotype "R" in both study years.

Results of two-year investigations (2000 and 2001) on the influence of seeding method and basic meteorological elements (precipitation and temperature) on yield and quality of fenugreek seed (Trigonella foenum graecum L.) are presented in this paper. Considerably higher yield of fenugreek seed in all variations was obtained in the second study year which was probably caused by more favorable precipitation during vegetation period.
