Production of occidental type of tobacco seedlings (Barley and Virginia) in our country, so far has been organized in traditional way. It considered tobacco seedlings production in semi hot hotbed, which has been heated with manure. Tobacco seedlings' production in qualitatively new way considers seed sowing in Todd's systems. The goal of this kind of researches is to compare these two ways of seedlings' production in economic way, i.e.

Intensively researching different populations of elecampane, we are able to present the results of yield achieved during three years' microexperiments (2001, 2002, 2003) realized in non-watering field crop production. Comparing the results of yield, it was concluded that all five populations had higher yield, both fresh and dry elecampane root mass, compared to standard cultivars called "Domaća".

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.
