No. 36 Irrigation of White Clover seed crops

Following a very wet winter, FAR has received a number of requests for information around managing yellow autumn sown crops. This Arable Extra outlines ways to distinguish between nitrogen and sulphur deficiencies and provides some information to support decision making around crop management.

This FAR Focus outlines the key practices required to grow cocksfoot seed crops, covering topics such as crop establishment, nutrient requirements, crop management and harvesting. Topics outside the scope of this booklet include emissions profiles and off-farm considerations such as seed cleaning etc.

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.

Pure Oil NZ and FAR are collaborating to monitor oilseed rape (OSR) paddocks to identify strategies to improve yields. Their work has identified that many growers could reduce the amount of nitrogen applied to OSR crops without impacting on yield or profit.

This handout covers herbicide resistance management, PGRs, nitrogen and disease management.

Moisture probes are a valuable tool for managing the timing and application rate of irrigation, particularly for determining when to start and finish the irrigation season or following rainfall and for when drought intensities increase at unexpected rates. Read more below.
