This paper presents the results of the first extensive archaeobotanical research into a Bronze Age site in Croatia. The aim of the study was to reveal what plants were consumed (grown) at Kalnik-Igrišče (NW Croatia) in the Bronze Age and to realize if the plant diet of the local population differed from that of the inhabitants in neighboring countries.The results show that all plant macrofossils found at Kalnik-Igrišče can be classified into one of four functional groups: cereals, cultivated legumes, useful trees and weeds. As much as 98% of the findings are of cereals and legumes. The most abundant species found are Panicum miliaceum (millet), Hordeum vulgare (barley), Vicia faba (faba bean), Triticum aestivum ssp. aestivum (bread wheat), Triticum turgidum ssp. dicoccon (emmer wheat) and Lens culinaris (lentils). The findings from Kalnik-Igrišče do not differ from the findings of neighboring countries, indicating that there were similar diets and agricultural/plant-collecting activities throughout the whole of the studied area

-In order to determine the infl uence of recovery techniques with water (fl otation and wet sieving) on carbonized plant remains, a certain amount of wheat, barley, millet, horsebean and lentil macrofossils from archaeological sites was taken and treated with water. Moist recovery was also applied to in-laboratory, artificially, charred barley, millet and lentil samples. After the treatments, the investigated remains were re-counted and the percentages of still recognizable remains for every plant species and for each method were recorded. Comparisons were made of the sensitivities of the investigated species and of the differences in the degree of macrofossil breakup depending on the method of recovery. Our investigation proved that fl otation is a less aggressive method than wet sieving and that barley, horsebean and wheat carbonized macrofossils are resistant to moist treatments, while the breakup percentage of lentil and millet (from archaeological sites) is higher than 30%, which should be taken into account when deciding on the (non)use of water recovery in the investigations.
