Effect of repeated hoeing on growth of Cirsium arvense Organic Eprints
Graglia, Enrico; Melander, Bo; Grøndal, Henrik; Jensen, Rikke K..
Infestation with Cirsium arvense in organic cropping is an increasing problem in many parts of Europe. In the present study, repeated hoeing during the first part of the growing season is suggested as a mechanical control strategy, aiming at diminishing the regenerative capacity of C. arvense. Results showed a linear relationship between the number of hoeing passes and the aboveground biomass of C. arvense in the subsequent year. However, the strong effect on the biomass of C. arvense was not followed by an increased crop yield. A low initial density of C. arvense, which did not cause any measurable yield loss, most likely explains this

Har Ager-Svinemælk og Ager-Tidsel skudhvile? Organic Eprints
Grøndal, Henrik; Graglia, Enrico; Jensen, Rikke K..
Rodukrudt er et stigende og udbredt problem i specielt økologisk jordbrug inden for de nordiske lande, hvor specielt arterne Ager-Tidsel og Ager-Svinemælk optræder som problemukrudt. For at kunne udføre en effektiv bekæmpelse, er det nødvendigt at kende de faktorer som bestemmer om planterne er i hvile.

Selectivity of weed harrowing in lupin Organic Eprints
Jensen, Rikke K.; Rasmussen, Jesper; Melander, Bo.
Three field experiments were conducted in lupin in 1997, 1998 and 1999 to study two aspects of selectivity of post-emergence weed harrowing; the ability of the crop to resist soil covering (the initial damage effect), and the ability of the crop to tolerate soil covering (the recovery effect). Each year soil covering curves and crop tolerance curves were established in three early growth stages of lupin. Soil covering curves connected weed control and crop soil cover in weedy plots, and crop tolerance curves connected crop yield and crop soil cover in weed-free plots. The experiments showed that both resistance and tolerance were unaffected by the growth stage of lupin within the range from the cotyledon to the 7 to 8 leaf growth stages. Tolerance to soil...
