In a field trial in 1966-8 at Nitra, winter wheat Bezosta 1, Diana 1, Fertodi 293 and Kosutska were sown after ploughing-in lucerne after the 2nd or 3rd cut of lucerne. After ploughing, the soil was not treated, was rolled, compacted with a heavy roller or was rolled and compacted, and after sowing the soil was not treated, was rolled immediately after sowing or in spring, or was rolled after sowing and again in spring.
