Summary
By increasing the row spacing from 12.5 cm to 25 cm in your spring cereal grains it will be possible to both carry out weed control and simultaneously establish a nitrogen-fixing catch crop between the grain rows. As long as the number of plants is maintained when increasing the row spacing and crop damage is avoided, a row spacing up to 30 cm will not result in yield loss.
Weed control between the rows results in more than 75% reduction in number of weeds, although aggressive species were reduced less.
Weed control between the catch crop rows after harvest reduces perennial weeds.
Summary translation
Ved at øge rækkeafstanden fra 12,5 cm til 25 cm i din vårsæd bliver det muligt både at radrense og samtidig etablere en kvælstofsamlende efterafgrøde mellem kornrækkerne. Så længe plantetallet fastholdes, ved en øgning af rækkeafstanden, og afgrødeskader undgås, vil en rækkeafstand helt op til 30 cm ikke medføre udbyttetab.
Ukrudtsbekæmpelse mellem rækkerne resulterer i mere end 75% reduktion i antallet af ukrudt, selvom aggressive arter blev reduceret mindre.
Ukrudtsbekæmpelse mellem rækkerne med efterafgrøder efter høst reducerer flerårigt ukrudt.
