Contents: The influence of different tillage variants and low herbicide doses of triasulfuron & chlortoluron mixture (Dicuran forte 80 WP) on weed populations and crop yield were studied in spring barley on lessive pseudogley soil in North-Eastern Croatia at the Čačinci locality in 1999. Tillage had no significant influence on annual broad-leaved weed biomass production, which was 22 kg ha-1, on the average. Chisel ploughing and disk harrowing significantly increased perennial weed biomass by 21 and 44 times, respectively compared to mouldboard ploughing. The average efficacy of total weed biomass control was 95, 89 and 81% at full, onehalf and one-quarter of the recommended herbicide dose, respectively and did not differ very much between tillage treatments. Both reduced herbicide doses ensured very good biomass control of the most abundant weed populations such as Ambrosia artemisiifolia L., Chenopodium album L., Ch. polyspermum L. and Polygonum lapathifolium L. No significant tillage and herbicide dose effects were recorded in barley yields, which ranked from 4.93 t ha-1in chisel ploughing to 4.48 t ha-1in disk harrowing. These results suggested a possibility of mouldboard ploughing substitution with reduced tillage practices on lessive pseudogley soil and herbicide dose reduction of triasulfuron & chlortoluron mixture to 50% or more in spring barley.
