Sažetak
The yield responses of winter wheat and spring barley to different tillage variants and to dose reduction of triasulfuron & chlortoluron herbicide mixture were studied on lessive pseudogley in the north-eastern part of Croatia during 1997-2000. No significant yield differences (* P<0.05) were observed between conventional tillage with mouldboard plough and reduced tillage variants (chisel ploughing, disk harrowing, disk harrowing alternated with mouldboard ploughing every second year and mouldboard ploughing alternated with disk harrowing every second year), although the average wheat yield of 5.7 t ha-1 and barley yield of 4.9 t ha-1 were the highest after chisel ploughing. The herbicide dose reduction to one half and one quarter of the recommended rate provided still good control of the total weed dry weight in terms of both crop yields, in all tillage variants. The average yield from treated plots was 6% and 4% higher in wheat and barley, respectively compared to untreated plots.
