Abstract
In pot trials, (a) meadow fescue and (b) timothy were given 0-2 g N/pot immediately after the 1st cut taken on 23 June. Initial regrowth was faster in (a) than in (b) and with 0.5 g than with 1 or 2 g N/pot. In (a), DM yield increase/g applied N was greater with 0.5 g than with 1 g N/pot in 7- to 28-day-old regrowth and in 56- and 63-day-old regrowths, and than with 2 g N/pot in all except 49- and 84-day-old regrowths. In (b), DM yield increase/g applied N were greater with 0.5 g than with 1 g N/pot in all except 70- and 77-day-old regrowths and than with 2 g N/pot in all regrowths. N uptake increased with increase in N rate and in length of regrowth period.
