    Saabunud / Received 27.01.2023 ; Aktsepteeritud / Accepted 24.06.2023 ; Avaldatud veebis / Published online 15.08.2023 ; Vastutav autor / Corresponding author Helena Madsen ; helena.madsen@emu.ee The effects of long term (established in 2008) five-field crop rotation (barley (Hordeum vulgare L.) with undersown red clover (Trifoium pratense L.), red clover, winter wheat (Triticum aestivum L.), pea (Pisum sativum L.), potato (Solanum tuberosum L.)) on the biomass, abundance and diversity (Shannon-Wiener index) of weeds in three organic (Org) and two conventional (Conv) systems after the second rotation were investigated. The results include data from the second rotation in 2013 – 2017. The control system (Org 0) followed only the crop rotation. In the organic systems Org I and Org II winter cover crops were used. In Org II system composted cattle manure was also applied. The conventional cropping systems were treated with herbicides and fungicides and system Conv 0 acted as control (no fertilizer use). Mineral fertilizer was used in Conv II. In general, the significant differences were evident between conventional and organic cropping systems. There were also some differences depending on the crop. The weed biomass was the lowest in barley and potato plots, with significantly higher values in organic than in conventional systems. In clover plots the highest biomass of weeds occurred in Conv II whilst the lowest in Org I. In winter wheat plots the biomass of weeds was significantly lower in conventional systems than in any of the organic systems. Pea plots had the highest biomass, abundance and diversity of weeds in all systems within all rotational crops. Slight tendencies showed the decrease of weed abundance and diversity at the end of the rotation in systems with cover crops (Org I and Org II). This could be explained by better growing conditions due to higher microbial activity and organic carbon content in the soil of organic systems.
