“…Each year there was a tendency for lowest yields to be in the plots that were weed-harrowed twice, although cereal plants can recover from physical disturbance (Sobkowicz et al 2020). Our yield results slightly overemphasize crop damage because the crop was harvested from a 5 m wide mid-strip, which included stamped tractor tracks, rather than a 9 m wide weed-harrowed plot with a higher proportion of non-stamped area.…”

“…Detailed studies on weed harrowing in cereals include specifications for timing, machinery and its settings, number of passes, driving speed, harrowing direction, and mechanism of control, in general resulting in varying effects on weeds in different soil types and moisture conditions, crop damage and yield response (Wilson et al 1993, Rydberg 1994, Rasmussen and Svenningsen 1995, Cirujeda et al 2003, Sobkowicz et al 2020. Therefore, instructions and recommendations for efficient weed harrowing are readily available to adjust and apply according to prevailing conditions.…”

Spring-tine harrowing is a common physical weed control practice employed in organic cereal cropping. The effectsof harrowing treatments on weeds and crop yield were studied in a field experiment of organically grown springcereals during 2018–2020. The objective was to demonstrate the feasibility of weed harrowing to enhance overallweed management in organic cropping in Finland. Single post-emergence weed harrowing, with or without covercrop drilling, at the 2–4 crop leaf stage was compared with a combined pre- and post-emergence weed harrowing.Treatments were repeated in the same plots for three years and weed occurrence was assessed prior to harrowing,two weeks later and at harvest time. Chenopodium album was the predominant weed species in all years.Although harrowing effectively reduced the weed abundance, which was best with the double treatment, the yieldresponse in terms of quantity and quality was negligible. Even so, weed harrowing in cereal years is recommendedto suppress weed proliferation in crop rotation.

Cultivation of spring cereal mixtures (SCMs) is one of the ways to increase the yield of crops in mountainous areas of Poland. There are only a few current long-term studies on this topic. Our study aimed at analyzing yield and competitiveness as well as the economic indicators of spring cereals in pure or mixed sowings in integrated or organic crop rotations over nine years. A field experiment including pure sowings of oats, spring barley, or spring triticale and their two-component SCMs, each in two systems, organic and integrated crop rotation, was carried out in the Mountainous Experimental Station in Czyrna, Poland, in the years 2011–2019. On average, cereals in the pure sowings and mixtures yielded 18% lower in the organic rotations compared with the integrated ones. However, SCMs yielded higher than the pure sowings, and displayed a higher leaf area index and land equivalent ratio. The average gross margin without subsidies was almost two times higher in the organic crop rotations than in the integrated ones, which was influenced mainly by the cultivation of barley in pure sowing. Summing up, the cultivation of SCMs in the mountainous areas of southern Poland is advised because of both productive and economic factors.
