Field trials at two sites assessed the effects of different husbandry practices on seed yield and oil content of linseed (Linum usitatissimum L). A pot experiment investigated very early sowings. In the field trials maximum seed yields were achieved from sowings over a longer period at Elgin than at Aberdeen. Sowings in pots before mid‐March resulted in poor plant establishments. Yields responded to nitrogen fertiliser levels greater than 40 kg ha−1 only on the lighter Elgin soils. There appeared to be no yield advantage from establishing more than 400 plants m−2 at either site. Plant growth regulators reduced plant height and, where lodging was reduced, increased yield. Seed oil contents were influenced more by environment than by husbandry; high nitrogen applications on light soils gave significant reductions in oil content.
