Response of flue-cured tobacco to reduced fertilization

The aim in flue-cured tobacco production is to produce high quality leaf competitive on world market in price and quality. Rationalization of fertilization would decrease production costs, and diminish negative overfertilization effect on environment. Cultivars of Croatian flue cured tobacco were planted at two fertilization rates 60 kg N, 35 kg P2O5 and 210 kg K2O per ha, and 40 kg N, 25 kg K2O and 150 kg P2O5 per ha, at two locations, Kutjevo (silt loam soil), and Virovitica (sand loam soil), during three years. The lower fertilization resulted in better agronomic traits and lower production costs than the higher rate. The studied traits were more influenced by location then by fertilization rate.
