Studies on the Development of White Clover Seed

Arrowleaf clover (Trifolium vesiculosum L.) is a late maturing annual legume which has the potential to be used in a range of farming systems such as finishing lambs through to silage production and building soil fertility for future cropping. An experiment at Lincoln University, Canterbury, evaluated the performance of 'Arrotas' arrowleaf clover relative to white and subterranean clover from 23 May to 20 December 2007. By the 20/12/2007, 'Arrotas' produced 9800 kg DM/ha compared (P<0.001) with 3370 kg DM/ha from subterranean and 1790 kg DM/ha from white clover. Metabolisable energy in late December was similar for all clovers. Results in Australia at similar latitudes and rainfall regimes to parts of the North and South Island of New Zealand suggest that 'Arrotas' could be successfully incorporated into local dryland systems.

Maximum potential harvestable and actual seed yield of white clover (Trifolium repens L.) cv. Grasslands Pitau following a mid November closing at Palmerston North, New Zealand, was obtained at a harvest 25 days after peak flowering. Seed yield did not differ significantly when harvest was delayed from 25 to 35 days after peak flowering, but was significantly lower with harvests at 40 and 45 days after peak flowering. This response to time of harvest was not altered by applying the growth retardant paclobutrazol (applied at 1.0 kg a.i./ha on 27 November), as peak flowering and seed development (as recorded by seed weight and moisture content) did not differ between treatments. There was, therefore, no evidence to suggest that paclobutrazol-treated plots should be harvested at a different time to that of control plots. Paclobutrazol significantly increased Corresponding author A94006 inflorescence number at peak flowering and the first harvest, but the 56% difference in seed yield between the treatments failed to reach significance. Possible reasons for this result are briefly discussed.
