Rasad virdžinijskih duhanskih hibrida DH16 i DH17 je uzgojen na tri hranidbene otopine i posađen u poljskom pokusu u Kutjevu i Virovitici 2000. i 2001. godine. Pokus je izveden po randomiziranom potpunom blok rasporedu u 4 ponavljanja i sa 4 reda po 22 biljke na pokusnoj parcelici. Srednja dva reda, bez rubnih biljaka (40 biljaka) su korištena za procjenu prinosa, cijene i vrijednosti duhanskog lista nakon berbe i sušenja. Preporučene koncentracije hranjiva u hranjivoj otopini kod nas u proizvodnji su N:P:K= 150:75:150 ppm. U pokusu su korištene koncentracije N 150 i 170, P2O5 75 i 150, te K2O 150 ppm. Analize za sva svojstva rezultirale su značajnim razlikama u okolinama (lokacija x godina), dok je za cijenu i vrijednost signifikantna bila interakcija hibrid x okolina. Obzirom na sortiment, hibrid DH17 je u prosjeku imao nešto bolja gospodarska svojstva od hibrida DH16. Izvor hranjiva u otopini, kao niti njihova koncentracija nisu značajno utjecali na istraživana svojstva duhana. Stoga rezultati upućuju na mogućnost korištenja izvora hranjiva i njihove koncentracije u hranjivoj otopini korištenoj u pokusu za uzgoj rasada hibrida duhana DH16 i DH17.Seedlings of flue cured tobacco hybrid DH16 and DH17 grown in float system on three nutrient solutions were transplanted in a field experiment at two locations in 2000 and 2001. The experiment was organized as RCBD with four replicates and four 22 plant rows per each experimental plot. Middle two rows (40 plants) were used for analyzing yield, price and value. Recommended nutrient concentration for float system in Croatia is N:P:K = 150:75:150 ppm. In the experiment concentration of N was 150 and 170, of P2O5 75 and 150, and of K2O 150 ppm. The obtained data analyses resulted in significant differences between environments (year x location) for all the traits, while hybrid x environment interaction was significant for price and value. Hybrid DH17 was on the average slightly better than DH16 in all the traits. Source of nutrients and nutrient concentration did not have significant effect on the tobacco traits. The obtained results have indicated that the fertilizers and the nutrient concentration applied in the experiment can be used in the commercial tobacco production of the hybrids DH16 and DH17
