The aim of the research was to study weed species occurrence and abundance in field bean (Vicia faba L.), maize (Zea mays L.), potato (Solanum tuberosum L.) fields and in perennial grasslands in Kurzeme region. Above mentioned crops and perennial grasslands were chosen for analysis as a part of seven-year-long weed survey performed in 14 conventional farms. Six constant fields per farm were monitored each year. The analysis of weed survey results showed that the main weeds in crop fields were annual dicotyledonous weeds, but perennial weeds were typical to perennial grasslands. Field horsetail (Equisetum arvense (L.)) had high occurrence and abundance in all studied crops in the 56 surveyed fields. The largest number of weed species was observed in field bean sowings, but the smallest – in maize sowings and perennial grasslands.
