Tiivistelmä

Cloudberry (Rubus chamaemorus) production was studied in 1979 in four mire site types. The number of sample plots (4 m2) was 272. RaR and IR site types were studied both in the virgin and drained state. The crop values obtained (VNR 40.6 kg/ha, others 26.5—31.6 kg/ha) were rather high compared to those of earlier studies. This was probably due to the absence of night frost during the flowering period. In drained site types the mean crops were appr. 74 °/o of those in virgin bogs. In drained IR the cloudberry crop was appr. twofold compared to that of the drained RaR.
