  • No 62 Late Season Manipulation Of Crop Bulk In White Clover Does It Pay

No. 62 Late season manipulation of crop bulk in white clover - does it pay?

Feature placeholder

Key Points

  • Only one of 10 experiments gave a significant seed yield response to mechanical topping of white clover seed crops.
  • There was a trend for topping to increase seed yield as the amount of dry matter removed increased above 2000kg DM/ha (when topping at 70mm height at first flower) with heavier soils tending to be associated with seed yield increases.
  • Soil characteristics (and possibly location, temperature) influenced the response to topping.
  • The application of 2,4-D Ester suppressed seed yields when applied at 2 and 3l/ha in July at four sites in the 2007/08 season. Late season herbicides (applied at first flower) showed variable results but did not enhance seed yield.
  • Moddus applied at first flower reduced seed yield.

H78 Managing white clover desiccation in challenging seasons

This update outlines the results of five years of trials exploring pre-desiccant options for managing bulky white clover crops, aiming to reduce rapid leaf regrowth following diquat desiccation under wet or high-fertility conditions. Achieving effective desiccation required balancing this process with post-harvest regrowth, as clover seed crops are often used for lamb grazing on New Zealand cropping farms.
